Update on Alternative Cylinder Surfaces. As the market pressure increases for shorter press runs, quicker project starts and continuing price increases of steel bases, gravure printers are being squeezed. Two of the leading alternative cylinder surface systems developers will provide the latest from beta sites as non-metal surfaces that do not need to be chrome plated are becoming a reality. The ultimate goal of the Kaspar Graphic Solutions “Helio-Pearl” and the Rossini “Eco-Grav System” is to provide a complete cylinder coating system that will allow the gravure packaging printers to be able to engrave cylinders in-house. Without the need that requires a surface coating like chrome, the new systems will not have the regulatory burden that comes with a chrome plating tank. The two back-to-back presentations are a must for those looking to bring cylinder engraving in-house. Go to: 2023 R2R USA Registration (rolltoroll.org)

Abstract

Inks for Li-ion battery anodes were formulated for printing with the rotogravure printing process. Graphite powders with different particle sizes were used as conductive materials along with nanoparticle carbon black fillers. As polymer binders, polyvinylidenefluoride PVDF (commercial names Kureha 9100 and Kureha 9300) and polyvinyl pyrrolidone (PVP) were tested. Inks were printed using proprietary gravure engraving. Ink solid content of 30-70% was examined. At 70% solids, ink layers were 25-27 µm thick with mass loading of 2.1-2.5 mg/cm². A solids content found of 50% was the highest that produced a smooth uniform film. Half cells were made using print with 1000 µm holes or they were bar coated. Half cells were charged and discharged in order to measure irreversible capacity loss (ICL). Inks with mixed binders Kureha/PVP were performing better than sole polymers. Half- cell testing revealed that PVP as a sole binder has not good electrical performance, thus it was mixed with PVDF. The ICL was lower when mixed PVDF/PVP binder was employed in anode ink.

Introduction and Background

Due to the increasing impact of oil pollution on the environment (CO₂ production and liquid spills), more automobile and many other industries have turned to electric item manufacturing. Therefore, the production of more energy-efficient and environmentally friendly batteries has become a hot topic at the moment. The traditional lead-acid battery is bulky and heavy, but the printing processes can produce much thinner and lighter batteries to provide power for wearable devices, flexible displays, and smart labels among others (Costa, et al., 2020; Khan et al., 2015). With the advent of printed electronics, flexible batteries have undergone rapid development in the past ten years. The use of printing processes in battery manufacturing can lead to mass production of flexible batteries (Arduini, 2016). Printing can produce flexible batteries with different design patterns, and their multilayer printing stack can shape the geometry and structure of the battery and improve its electrochemical performance. There are usually two types of the printed structures of printed batteries, such as stack or sandwich architecture and the coplanar or parallel architecture. Components used are anode, separator, electrolyte, cathode, and current collectors deposited on the flexible substrate (Lanceros, 2018). Most of the batteries are manufactured in a stacked structure (Willert et al., 2018), while some are made in a coplanar configuration (Kim et al., 2015). The advantage of coplanar configuration is that it, among other manufacturing processes, can be made using the screen-printing process and the total thickness of the battery can be reduced to 0.5 mm. Its disadvantage is that its discharge current and area ratio charge density is lower, and it has a higher internal resistance.

Currently, many researchers are focusing on screen printing of battery electrodes. This printing technology can use high viscosity inks for printing, which allows them to have good coverage on different materials, such as copper foil (Vicco, 2021), or plastic (Zhao and Wu, 2019), which are suitable for printing lithium -ion battery electrodes (Khan et al., 2015). Based on the size required to print battery electrodes, the amounts of active materials, the roughness of the electrode layer, and the thickness of each layer of the battery can be modified. There have been many studies using printing methods such as gravure printing, flexographic printing, screen printing, extrusion printing, and inkjet printing to explore battery electrode production (Søndergaard et al., 2013, Huebner, 2015) as well as attempts to print electrolyte (Huebner, 2022). Lithium metal powder-based inks, which contain lithium metal powder, polymer binders, and other conductive materials can be used in anode printing. In general, the advantages of printed batteries are based on mature printing technology, and the fact that they are light, flexible, low cost, can be mass-produced, customizable, and more environmentally friendly.

Research in the printed batteries based on gravure printing showed that the quality of the gravure printing layer mainly depends on several physical parameters such as ink, substrate, and process. To enable the mass production of batteries through gravure printing, the study was done using carbon coated Zn_0.9Fe_0.1O (encapsulated in a thin film of carbon) as a reference alloying material (Bresser et al., 2013). With the water based electrode inks, 2-propanol can be used as a cosolvent to reduce the excessive surface tension of water-based inks in combination with corona pretreatment of the substrate for increased surface energy and thus ink adhesion (Biscay et al., 2011). Using the gravure printing process, multiple layers can be deposited, and the multilayer method applied is able to obtain the required mass loading (about 1.7 mg cm^-2) to achieve high homogeneity of the gravure printing layer, and its highly reproducible electrochemical performance up to 400 life cycles (Montanino et al., 2021).

Printing inks for anode and cathode inks contain active materials, such as graphite, graphene, and active fillers such as nanocarbons, and resins or binders, which are selected based on ink chemistry whether ink is solvent, or water based. Graphene can be doped by ball milling technique, and can be combined with silicon, silicon oxide, iron oxide for improved performance (Yu et al., 2022). Resins can include litiated polyacrylic acid, or polyvinylidene fluoride of different degrees of polymerization. The advantage of printing batteries is that layers of variable thickness can be produced. Printed layers are flexible, and they can be integrated into various substrates and devices. Printing technologies make it possible to easily scale up the products (Costa et al, 2020). Printed layers should be thick, preferably up to 100 µm and therefore screen-printing is the process of choice (Rassek et al., 2019). There was not much information found specifically in gravure printing of anodes and cathodes, which calls for need to explore gravure process for printing these features for batteries. In this work, the aim was to formulate rotogravure printing inks for anodes and evaluate their printability in terms of print uniformity, thickness of the layers and ultimately, half-cell battery performance.

Materials and Methods

The substrate for anode Li ion battery printing was copper foil from MTI Co., with caliper of 9 µm. Its surface roughness was 0.32 µm as measured by Bruker white light interferometry. Sheet resistivity of Cu foil was measured using SRM-232 sheet resistance meter with four-point probe and it was 0.0018 Ω/sq. Surface energy of copper foil was measured via contact angle with water: 87.2 ± 1.3 ° and hexadecane: 3.3 ± 0.1 °, as well as surface tension of water via pendant drop measurement: 71.1 ± 0.6 mN/m; surface tension of hexadecane via pendant drop measurement: 24.5 ± 0.3 mN/m. These values were plugged into the Owens –Wendt equation and surface energy of copper was estimated to be 26.5 ± 0.7 mN/m.

A Thinky Mixer AR 100 (THINKY Co., Tokyo Japan) was employed for mixing the inks. As the conductive graphite powders, Philips 5 µm, 10 µm, 15 µm (Philips 66, Houston, Texas) and Mage 3 graphite (Hitachi Chemical, Sakuragawa, Japan), and conductive nanoparticle carbon black filler (CB 4400 or C45) with particle size of 20 nm were used. Polyvinylidenefluoride (PVDF) from Sigma Aldrich with different degrees of polymerization and commercial names Kureha 9100, Kureha 9300 (Kureha Co., Japan) with molecular weights of 2.8×10⁵ to 1×10⁶was dissolved in N-methyl-2-pyrrolidone (NMP) solvent and used as the vehicle. In some inks, a polyvinylpyrrolidone (PVP) with molecular weight of 10000 or polyvinylpyrrolidone/polyvinylidene fluoride mix of binders (PVP/PVDF) was employed. Rheology of finished inks was evaluated on an Anton Paar MRC302 rheometer.

Printing was done on Cu foil using a gravure RK gravure K-proofer (Figure 1), which uses a flat plate as an image carrier. The gravure plate for the RK gravure K-proofer was engraved by WRE /ColorTech (Greensboro, NC, USA) with proprietary engraving at 75 LPI. A plate was engraved with 1000, 500, 250 and 125 µm circular hole shaped nonimage areas. Detail of 500 µm nonimage area is shown in Figure 2 and white light interferometry detail is shown at Figure 3, showing depth of cells at 75 µm and the cell opening in one direction of the 1000 µm designed hole was measured at 1194 µm. Engraving was done by hybrid process of laser ablation and chemical etching. Such holes in the printed image improve the battery performance at high C rates and reduce Lithium dendrites that collect on the electrodes (Emani, et al., 2022, Palaniappan, et al., 2022).

The profile of the plate and ink films was prepared on a Bruker white light interferometry instrument. Image analysis of printed ink films was done using Pax it 2 software.

In order to test irreversible capacity loss of anodes, half coin cells were constructed (Figure 4) in a glove box to avoid moisture and oxygen damage. A half-cell contains a conductive electrode, conductive electrolyte and a current collector. Reversible/irreversible capacity and stability of the electrode can be obtained from the galvanostatic cycling technique (Figure 5). The galvanostatic cycling technique provides information about reversible/irreversible capacity and stability of the electrode.

Results and Discussion

Anodes for Li Ion battery electrodes were printed with long chain polyvinylidene fluoride polymer inks. As active materials graphite powders of different particle sizes were employed. Graphite powders are deemed to be efficient and economical conductive materials; thus, they were considered very suitable for this work. At this stage, particle size of the graphite powders 5-22 µm was assessed, thus only the graphite part of the ink formulation was changed, and the rest of the formulation was held the same (Table 1). Solid content of all four inks was kept at 50%, because higher solid content could not be printed uniformly on the designed structure of gravure plate. As a binder, Kureha 9300 polyvinylidene fluoride (PVDF) was used and as a solvent, N-methyl pyrrolidone (NMP) was employed. PVDF is a highly non-reactive thermoplastic fluoropolymer. It is a special polymer used in applications requiring the highest purity as well as resistance to solvents, acids, and hydrocarbons with excellent mechanical properties. It was selected because it is a known binder for carbon electrodes in supercapacitors and other electrochemical applications. NMP was selected as a solvent for this system because of his high chemical and thermal stability, and compatibility with many solvents such as alcohols, ketones, chlorinated and fluorinated hydrocarbons.

Table 1: Gravure Anode Ink Formulation

Formulated inks were tested for their rheological properties (Figure 6 and 7). Viscosity of polymer suspensions usually increases with increased degree of polymerization, and higher solids content. At certain composition, its viscosity is reduced by increasing the applied shear rate, because the bonds between the polymer chains are broken (Triantafillopoulos, 1988). Tendency of ink to lose viscosity when stirred is called pseudoplasticity. This property favors the ink in the moment of printing because it flows more easily. When the stress or shear rate is decreased, the viscosity of polymer suspensions or inks is regained, e. g. when ink is printed its viscosity increases again, which helps the ink to set on the substrate and create required print features. Not all inks set at the same speed. The speed at which the structure is restored is called thixotropy. Figure 7 shows that all the tested inks after increased shear drastically decreased in viscosity, but after returning to the original shear rate, the viscosity is regained, which shows that all of those inks display thixotropic behavior. The highest viscosity was found for ink with Philips 5 µm, while the inks with Mage 3 and Philips 15 µm had the lowest viscosity. Pseudoplastic behavior of the inks was confirmed in regime of shear rate of 0.1-200/s for the flow curve. All of inks were shear thinning (Figure 6).

All of these inks were printed on an RK gravure K-proofer (Figure 1), and these experiments showed that ink containing graphite powder with 5 µm particle size exhibited the best print quality. The reason may be that the 5 µm graphite particle size could deposit the ink film with lowest primary porosity and the best ink film integrity. Also, 5 µm particle size of graphite probably enables easiest ink release from gravure image carrier. Overall, all applied PVDF inks seem to have too high viscosity for rotogravure printing process. Therefore, we wanted to experiment with lower ink viscosity, for which a new resin polyvinylpyrrolidone (PVP) at 10,000 molecular weight was tested to disperse graphite and nanocarbon active materials. Inks with 30-72% solids were formulated with graphite from Philips (P5) with size of 5 microns, and conductive filler CB 4400 with the ratio of ingredients: Philips P5/CB 4400/PVP (80:5:15). As a solvent, ethanol or NMP were used. Ethanol was evaporating too fast, thus N-methylpyrrolidone (NMP) was chosen as a more suitable solvent. The average surface tension of NMP ink with 70% solids was 39.4 mN/m and average contact angle with copper surface was 40.8 ° (data not shown). At 70% solids, ink layers were 25-27 µm thick with mass loading of 2.1-2.5 mg/cm² (data not shown). PVP inks showed excellent dispersing characteristics and improved print quality when compared with PVDF ink prints. Printed inks with PVP resin are shown at the top part of the Figure 8. Gravure prints with N-methylpyrrolidone (NMP) as a solvent were easier to work with than using inks with water or ethanol as a solvent. Designed circular holes with diameter 1000 µm were resulting in printed circles 846± 20 µm in diameter, while 500 µm circular holes were printed with 219±11 µm diameter, smaller than those shown in Figure 3 (Figure 8 Top, Right and Left). Primary porosity of printed electrodes mostly depends on different particle size of active material, in our case graphite of different particle size 5-15 µm. Designed circular holes, or nonimage areas are responsible for secondary porosity. Precisely controlled porous architecture of electrodes is necessary for fast charging cells. Fast charging requires electrodes with high porosity and low tortuosity enabling fast electrolyte transport and at the same time prevent lithium plating (Mijailovic et al., 2021). Thus, circular holes, or non-image areas were designed on printed electrodes with the aim to create so called secondary porosity. Secondary porosity was found useful in suppressing Li dendrites formation in graphite electrodes at fast charging rates (see also Emani, et al., 2022, Palaniappan, et al., 2022).

Printed ink films on copper foil were used to construct half coin cells according to Figure 4. Half cells were used to assess reversible/irreversible capacity and stability of printed anodes. Irreversible capacity loss of half coin cells made with PVP inks was too high and half cells did not have sufficient electrical performance. Thus, in the next step PVP was mixed with PVDF – Kureha 9100 or Kureha 9300 and half cells were made again. The first attempts showed that mixing Kureha and PVP resins is possible, so far 2:1 ratio was tested, and inks exhibited uniform prints. Their performance in terms of irreversible capacity loss (ICL) was tested again (Figure 9). Inks were bar coated, not gravure printed to ensure higher thickness of layers than what was possible to achieve with gravure printing. Figure 9 should be compared with Figure 5.

From Figures 10 and 11, it can be seen that performance of mixed PVP/PVDF inks was greatly improved compared to PVP or PVDF alone, and mixed PVP/PVDF achieved actually better performance and suffered from less ICL than inks made with sole Kureha 9100 or 9300. PVP is known to have excellent dispersing properties. The macromolecule of PVP contains strong polar lactam hydrophilic groups and C-C long-chain lipophilic groups, which can be well compatible with a variety of solvents and can be coated on the surface of particles to form a good dispersion effect through steric hindrance. Introducing PVP, a polymer with an amphiphilic structure, onto the surface of graphite can significantly improve the dispersion properties of graphite in water, or organic solvents. Therefore, PVP can be used as dispersant for Li-Ion battery electrode inks and other conductive materials (Viaenne,2016; Annon, 2022). This is most likely the reason that PVP enhances the electrical performance of printed anodes in mixed PVP/PVDF inks. PVP with molecular weight around 10,000 creates low viscosity dispersions, which can be suitable for gravure printing, but as a sole binder it does not have sufficient mechanical properties needed for battery architecture. PVDF has large molecular weight (500,000-1,000,000) and its macromolecules create highly viscous dispersions, suited better for screen printing than for gravure printing.

Besides optimized viscosity, mechanical and dispersing properties, mixed PVP/PVDF suspensions exhibit intermolecular forces, beneficial for improved electrical performance. When the two binders PVP and PVDF (Figure 12) were mixed at the ratio 4:1 (PVP: PVDF) and allowed to stand for 0-24 hours, obvious darkening of color was observed in the mixtures. FTIR was performed on the mixtures to understand what may be contributing to color change and change in ink electrical performance. Binders were dried and ground, and FTIR was performed at 500 to 4000cm^-1(Figure 13). The FTIR spectrum showed broadening of O-H groups at 3434 cm^-1, and 3426 cm^-1which could occur due to stretching of O-H bonds. Stretching of C-H groups at 3000cm^-1 and C=O group at 1652 cm^-1was also observed, which strongly suggests the formation of hydrogen bonds between C=O groups of PVP and methylene groups of PVDF (Figure 12), which could lead to improved electrical performance of printed anodes. Similar behavior was found for PVDF Kureha 9100 and Kureha 9300 in the mixture with PVP.

Conclusions

Gravure inks for battery anodes were formulated and printed on a laboratory K-proofer with proprietary engraving. It was found that polyvinylpyrrolidone (PVP) inks showed good printability, but poor battery performance. Using mixed PVP/PVDF 9300 or PVP/PVDF 9100 binder combination could effectively improve battery performance without significantly sacrificing the printability. From several graphites having particle sizes between 5 to 15 µm, graphite with 5 µm particle size was the most suitable for gravure printing. Polyvinylidenefluoride (PVDF) inks under commercial name Kureha 9100 or 9300 with N-methylpyrrolidone (NMP) solvent showed best specific capacity during three charging/discharging cycles, and irreversible capacity loss was even lower when these PVDF polymers were mixed with polyvinylpyrrolidone. FTIR study showed that methylene group (-C-H₂) and carbonyl groups (C=O) demonstrated lower transmittance and O-H groups showed stretching. This clearly suggests the formation of hydrogen bonds. Hence, the hydrogen bonds formed between the methylene groups and carbonyl groups could be a contributing factor to the reduction of irreversible capacity loss (ICL) in mixed binder printed anodes.

Gravure AIMCAL Alliance Committee, Jim Garvey, the chair’s Corner!

Excitement is building for the R2R coming to Milwaukee!

As being new to the Association for Roll-to-Roll Converters (ARC) and the GAA (Printing) committee I am realizing how much ARC has to offer to its members. Looking over past members a large number who have dropped out are printer/converters. When I ask for reasons for not renewing, I hear budget reductions due to COVID, mergers, acquisitions, and retirements of those who participated. At the same time, I am told printer/converters are experiencing skill shortages from retirements.

I want to reach out to all who have not renewed letting you know, the GAA 2021 merger with ARC (AIMCAL) produced synergies with the GAA group bringing “Printers” and AIMCAL having “Converters” that were both suppliers/customers to each other. Now combined we are learning and growing with each other’s support.

The R2R USA venue is in Milwaukee, WI making it centrally located in the largest “Converting Corridor” in the U.S. to make it a driving destination. The R2R is a multi-track conference covering Flexible Packaging, Battery Manufacturing, Coating-Laminating, Adhesives, Web Handling, Gravure Printing/Coating and Sustainability. Go to: R2R USA Agenda (rolltoroll.org)

Again, I want to reach out to those Printer/Converters who need training and support to bring your new staff up to speed. The 2023 R2R is that opportunity where you can see how much more is available by being involved with ARC. Go to: 2023 R2R USA Conference (rolltoroll.org) and you will see the registration pricing is designed to give you the best “Value” to attend.

I encourage all GAA Committee members to reach out to all your industry friends and encourage them to attend the R2R. I am looking forward to meeting you all in Milwaukee.

Remember: The association exists only through the participation of its members and networking is the best way to stay current in the converting industry.

Automated Cylinder Cleaning: Here is the truth about cylinder cleaning.

Author: Patrick Potter, ppotter@flexowashus.com, President, Flexo Wash

Cleaning cylinders has traditionally been a dirty business and has long been a manual operation. Manual cleaning involves chiseling off dried ink and coatings from the ends and wiping down cylinders with solvents by hand. Whether this is a slow or a quick process, it is still a manual process performed by employees who are more and more valuable to your operation.

With all this effort, are your cylinders even clean enough? Not always.

Here is the truth about manually cleaning cylinders: It’s your time and money and with manual cleaning, both are increased.

While manual cleaning is relatively quick, it is inefficient and requires too much labor expense. There is also the matter of unnecessary cylinder damage, which will lead to poor print quality. Lastly, there are major safety concerns whenever manual cleaning and chemicals are involved.

If this sounds like your situation, the good news is that there is a way out. Let’s assess your situation and then we can focus on solutions.

Assess your pressroom:

What does your pressroom or work area look like?
Are your cylinders in good shape?
Does your cleaning keep up with your production?
Do you have dedicated employees responsible for cylinder maintenance?
Do you have a daily cleaning maintenance routine?

And most importantly:

Where is your process breaking down?

Downtime. Decreased production. Decreased labor force. Dirty cylinders. Inconsistent output. Low employee morale. Inability to keep up with production needs. There are solutions to all these pain points.

The Truth

Regarding your pressroom and your printing needs, let’s discuss the universal truth that all businesses either know already or need to know about the future:

Whatever CAN be automated WILL be automated.

Makes sense, right? Workers are harder to come by, but production needs to be maximized. Downtime is unacceptable and a huge liability. Businesses in the printing industry that formerly had full pressrooms of employees are a thing of the past. Automation is the future. Actually, automation is YOUR future.

Nobody can afford to waste the manpower, the valuable time or the poor output of manual cleaning anymore. The market is too competitive.

The advantage to automation is that it is constantly innovating. For converters, they can decide how much automation they want for their business, ranging from printing processes to cleaning processes. Depending on their points of pain and what level of production they need to achieve, the level of their automation is in their hands.

Another Truth:

Automation is easier than you think.

Did you know that you can clean your cylinders in just 5-20 minutes, depending on the solution?

Cleaning should not be the cause for your production to slow down. There are a variety of solutions from single to multiple cylinder cleaners that all can do the cleaning in 5-20 minutes.

Flexo Wash has two types of cylinder cleaners available:

Single/double cylinder cleaning:
Optimal for cleaning of less than 60 cylinders per day
Multiple cylinder cleaning:
Used for cleaning of more than 60 cylinders per day

The fully-automatic Cylinder Cleaners are designed to deep clean and restore gravure cylinders. Based on liquid and high-pressure water, this quick and gentle cleaning process leaves the cylinders totally clean and ready for immediate use. Total cleaning time ranges from 10 to 20 minutes and is gentle enough to allow for daily cleaning without causing any wear and tear to the roll.

These Cylinder Cleaners work with environmentally-friendly cleaning liquids, which are specially made for the deep cleaning of cylinders with all types of ink. There is also an option to use your own solvent blend. The water from the high-pressure rinse is automatically led directly to the drain, then to a tank for re-use or to one of our water treatment units. The water consumption is only ten liters for each roll meter.

The FACTS about Cylinder Cleaners

Proven technology
Offers AGILITY with a fast-cleaning process; approximately 10-20 minutes
Daily deep cleaning as often as you want
No wear and tear on roll
Works with Eco-friendly cleaning liquids
Effective on all ink types
Fully-automatic, closed-loop
Option for rotating brushes for deep cleaning system; no labor involved directly with cleaning

Either system works with sustainable cleaning solutions which will work with all ink types.

These machines can be equipped with rotating brushes, which make it possible to clean gravure cylinders in the machine. The brushes ensure in-depth cleaning of the engraved parts of the cylinder thus leaving it completely clean on all surfaces. The machines can be equipped with rotating brushes for cleaning of gravure cylinder ends, where there is often a heavy build-up of ink, which is difficult to remove.

The hard rotating and oscillating brushes will remove all ink from the shaft and end of the cylinder, making the cylinder clean on all surfaces. The cylinder can then be taken to production, storage or re-chroming without any manual treatment.

Proper cleaning is vital for your business. Eliminating your points of pain will increase production, decrease downtime and improve employee morale.

How about this for your new Truth:

Labor reallocation
Supplies expense down
Cells deep cleaned – process improvement
No longer using solvents to clean
Employee safety improved
Strong return on investment

The key to proper cleaning of your gravure cylinders is automation, and as we have described above, it is the most effective and simple way to get your cylinders completely clean and ready for the press again.

Visual Management for Print Manufacturing

By Greg Horney, Central Region Sales Manager, BST North America

To understand visual management, we need to define it. Visual management is simple signals that provide an immediate understanding of a situation or condition of a process. They are efficient, self-regulating, and worker-managed. This is a circular process as part of our daily process to quickly identify problems or cues to perform tasks, understand the signal, fix the problem, or perform the task and repeat as necessary.

Examples include:

• Color-coded dies, tools, or pallets
• Lines on the floor to delineate storage areas, walkways, work areas, etc.
• Improved lighting
• Inline production inspection

Visual management tools create a visual snapshot of how well our processes are being controlled or how well they are performing and reducing waste in less than a minute through posted 5S audit scores, 1-point lessons, light trees, and posted key performance indicators (KPIs) at each process.

As a process owner (working directly on the process), visual cues are key to reducing waste within the processes identifying issues early or as they occur by triggering a visible warning so we can react to it. Print-inspection cameras on presses can identify defects such as color variation, ink splatter, or missing print that trigger light trees and show the issues on monitors for the press operator to correct the issue quickly. This also allows for accurate press runs reducing the amount of overrun or the need for reruns because of underproduction due to waste. Proper visual management can improve makeready times by reducing the amount of time looking for tools (shadow boards), looking for dies or tooling (color coding), and having inputs to the process cued up and ready (job checklists), for example.

As a manager of multiple processes such as a department, production, or plant manager, visual management allows for quick understanding of how the production floor is performing. Running/stopped light trees on presses allow us to see what machines are running and which presses are down or going down frequently.

Live KPIs, such as overall equipment efficiency (OEE), yield, and waste, allow us to quickly see how a process is performing. These can be displayed on monitors at each process and fed directly to a central performance monitor showing all processes at a central location. Posted 5S audit scores show how well a process is being maintained and organized. The audit score also defines how effective the 5S efforts are on the overall efficiencies.

As an element of continuous improvement, visual management lends itself to the control phase of the DMAIC (define, measure, analyze, improve, control) Six Sigma process. Posted 1-point lessons ensure tasks are done properly while the different levels of signals, live statistical process control (SPC), flagging, or inspection is critical within the control phase of the process. In the control phase, using visual maintenance management boards helps keep machinery PMs on track to avoid unscheduled downtime.

If you look around, visual management tools are all around us. They come in many forms but must be implemented in a way that is unique to each process and need.

May 2023 Gravure Technical Article

The first in a series of Technical Overviews covering: Transitioning from Conventional Chrome to Laser-Engraved Cr²O³ in Gravure-Coating Station Cylinders

By John Rastetter, VP of Sales & Marketing, Pamarco

The gravure-coating process has become a critical component of industrial production spanning the medical, pharmaceutical, electronic, battery, and automotive fields, among others. Its unrivaled ability to apply a variety of materials such as adhesives, heat-resistant coatings, embellishments and texture-enhancing substances to a web surface has made it indispensable. Traditionally, this coating process has been accomplished using chrome rolls produced either by electromechanically or mechanically engraving, then hard-chrome electroplating. However, technological advancements have introduced the potential for using laser-engraved ceramic rolls, which may significantly improve service life and coatweight consistency over an extended period.

The transition from conventional chrome to laser-engraved Cr²O³ (Chromium Oxide) ceramic in gravure coating requires a thorough understanding of the implications for coatweight calculations based on volume. This article aims to provide a comprehensive guide on the considerations to be made during this transition and the methodology for calculating coatweight.

The shift to laser-engraved ceramic rolls is not a trivial one. These rolls are created using high-precision lasers that engrave a pattern into a ceramic-coated cylinder, thus allowing for a precise and consistent application of the coating. There are a variety of patterns to choose from that provide unique characteristics based on the rheology of the fluid being coated.

An example of a few cell designs would be Trihelical, 30-degree channel, 75-degree extended cell, and 60-degree. Choosing the ideal cell design will aid in applying the correct coatweight, ensuring consistency over time but just as important applying the coating uniformly. What I am referring to is the smoothness of the application, and the absence of pinholes and other visual defects. Selection is made based on the fluid being coated and the substrate it is being applied to.

One of the key advantages of laser-engraved ceramic rolls is their longevity. The hard ceramic surface resists wear much better than traditional chrome, leading to less downtime for roll changes and maintenance. Furthermore, the wide selection of cell designs combined with the volume consistency over time allows for a much higher degree of control over the volume of coating applied, leading to improved coatweight consistency.

However, transitioning to these advanced cylinders requires an accurate calculation of the volume required. The engraving volume, often referred to BCM (billions of cubic microns/in.²), plays a critical role in determining the coatweight, and hence, careful calculation is needed.

The coatweight is calculated by multiplying the cell volume by the number of cells per unit area. This is then adjusted by the efficiency factor, which accounts for the fact that not all the material in the cells is transferred to the web. The basic formula is as follows, but we also take into account the specific gravity and percent solids of the coating.

Coatweight = Cell Volume x Cells/Area x Efficiency Factor
In a traditional chrome cylinder, the cell volume is determined by the mechanical or electromechanical engraving process. However, in a laser-engraved ceramic cylinder, the cell volume is determined by the laser-engraving parameters.
Example of calculation for Volume (BCM)

Example of establishing Transfer Efficiency

In conclusion, the transition from conventional chrome to laser-engraved Cr²O³ in gravure coating brings significant benefits in terms of longevity and coatweight consistency over time. However, it also necessitates a detailed understanding of the differences in cell volume and geometry between the two types of cylinders. By carefully calculating these parameters, businesses can make informed decisions about whether to make the switch and how to optimize their coating processes with the new technology. Roller suppliers are your best resource when considering transitioning to the laser-engraved technology. Pamarco has a variety of tools and the knowledge to make this process painless.

“Strategies for Managing Episodic Hazardous-Waste Generation”

Presented by Julie LaRose, Waste Management Specialist –
Senior, State of Wisconsin, Department of Natural Resources.

Those who were able to attend learned the US EPA on November 28, 2016, EPA issued a rule that finalizes an update to the hazardous-waste generator regulations to make the rules easier for those classified as “very small quantity generators” or “small quantity generators” to maintain their generator category. The updated regulation allows for an “episodic” event that could allow disposal of an excessive amount of waste.

“Episodic events” refer to an activity or activities, either planned or unplanned, that do not normally occur during generator operations and result in an increase in the generation of hazardous wastes that exceed the calendar-month quantity limits for the generator. The map shows which states have adopted the Hazardous Waste Generator Improvements final rule and which states have been authorized by EPA to implement it. Remember, only very small quantity and small quantity generators are eligible for episodic events.

You can download the Webinar slides and other Wisconsin DNR supportive materials such as PDFs to help you understand “episodic-event” regulatory requirements: https://aimcal.sharefile.com/d-sb3c1e2bf18ee4f2fac12291421441ef7

Articles from May edition: Proposal to Strengthen Standards for Synthetic Organic Chemical Plants and Polymers and Resins Plants

On April 6, 2023, the US EPA announced a proposal to significantly reduce emissions of toxic and other harmful air pollution from chemical plants, including the highly toxic chemicals ethylene oxide (EtO) and chloroprene. The reductions would dramatically reduce the number of people with elevated air toxics-related cancer risks in communities surrounding the plants that use those two chemicals, especially communities historically overburdened by air toxics pollution, and would also cut more than 6,000 tons of toxic air pollution a year

EPA Takes Important Step to Advance PFAS Strategic Roadmap, Requests Public Input and Data to Inform Potential Future Regulations under CERCLA

On April 13, 2023, the US EPA issued an Advance Notice of Proposed Rulemaking (ANPRM) asking the public for input regarding potential future hazardous-substance designations of per- and polyfluoroalkyl substances (PFAS) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as “Superfund.”

This request for input and information follows EPA’s September 2022 proposed rule to designate two PFAS—perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), and their salts and structural isomers—as hazardous substances under CERCLA. EPA is currently reviewing comments received on this proposed rule.

Special Announcement!
The Association for Roll-To-Roll Converters (ARC) (formerly AIMCAL) has been added to the Wisconsin Printing Industry Green Tier Charter, joining the Wisconsin Dept. of Natural Resources, the FTA, PRINTING United Alliance, TLMI and the Great Lakes Graphics Association.

The GAA & GAA-Committee has participated in the WI Printing Industry Council for several years. After the merger of GAA into AIMCAL, ARC Executive Director Chris Kerscher saw it was advantageous for the association to become a member of the Green Tier Charter for Superior Environmental Performance within the WI Printing Industry Council.

Wisconsin is home to more than 30 ARC member companies, and the Wisconsin Printing Industry Council has been a leader in promoting open communication between the regulatory agencies and the printing/converting community. As society pushes for sustainability and a circular packaging economy, communication among the affected parties is more important than ever. The State of Wisconsin and all the signatories of the charter ratified the amendment to include the Association for Roll-To-Roll Converters. Chris stated that being included in the charter shows the association’s support to sustainability efforts for a better environment.

About the Wisconsin Printing Industries charter | | Wisconsin DNR

The charter provides a vehicle to improve sustainable business practices within the printing industry, while increasing regulatory efficiency in return. The charter contains commitments of value to both the department and the printing industry that provide environmental and economic benefits. This charter includes several overarching goals to:

Identify opportunities for improving compliance and regulatory efficiency. This includes streamlining current environmental regulations, creating new approaches to meet regulatory obligations, and developing and updating support and guidance documents.
Explore and promote alternative approaches to beyond-compliance environmental activities. This includes outreach to the industry about the Green Tier and SGP programs, sustainable green-printing practices and new technologies, new or revised regulations, and other resources.
Encourage printing companies to participate in Green Tier and SGP programs to take advantage of additional benefits [PDF]. This includes:
- Recognition at the state and national level
- Ability to apply efforts to both programs, including:
  - Working toward the same objectives and continuous improvement projects;
  - Providing progress updates in one annual report format; and
  - Conducting one audit to satisfy requirements of both programs.
A fact sheet [PDF] summarizes additional benefits for Wisconsin printers participating in both programs.

Cal Poly Graphic Communication provides update on its Gravure process training.

The K-Proofer was generously granted to Cal Poly Graphic Communication by the Gravure Education Endowment (GEF) and the Print Graphics Scholarship Foundation (PGSF) in Fall 2021. Since then, it has been used for teaching, research, and extra-curricular activities. The K-Proofer was integrated into hands-on learning activities for over 200 undergraduate students.

Students were taught the differences in gravure, flexography, lithography, and silkscreen printing processes. In particular, gravure was briefly introduced in GrC 101 Introduction to Graphic Communication. With the addition of the K-Proofer, we could incorporate more in-depth explanations of gravure in multiple classes, including GrC 211 Materials for Graphic Communication Applications, and GrC 328 Digital and Offset Printing Methods.

In GrC 211, with the help of the K-Proofer, students had hands-on experience with gravure ink by measuring ink viscosity and making proofs. In GrC 328, students get a deeper understanding of the differences between analog-printing processes. Students are introduced to the printing principles, press technologies, sustainability challenges, substrates, and inks considerations of the Gravure process. Consequently, students will thoroughly understand how gravure is different from flexography, as gravure controls both the area of ink coverage and ink-film thickness in the same print unit.

In the lab activities, students could observe the gravure plate from K-Proofer under the microscope. Then they are provided with real-world print samples to analyze the print features, quality, and volume. At the end of the class, students felt more comfortable analyzing different print samples and associating them with specific printing methods by identifying the end-use of the sample and analyzing the print features, such as halo edge from flexography and serrated edge from gravure.

Moreover, students also learn color-matching by using the spectrophotometer on the print samples from the K-Proofer.

Cal Poly’s Graphic Communication Department is very thankful that PGSF and GEF support schools like ours. With the K-Proofer in our labs, students are empowered with hands-on experiences that deepen their understanding of gravure technology.

We want to thank Ruoxi Rachel Ma, Ph.D., Assistant Professor, Graphic Communication, California Polytechnic State University, for providing the article and supporting the gravure process to her students.

GravurExchange asked BOBST to provide our readers with the latest R&D concerning increased pressure to make packaging more sustainable using paper-based substrates.

Sustainability through fiber-based substrate adaptability

These projects are identified by two umbrella terms – oneBARRIER and “One” complete solution – and address two key focal points for the flexible-packaging industry: the recyclability / circularity of packaging, and the transformation of the production workflow. Both are crucial and connected. As an end-to-end packaging solution provider, BOBST needs to consider the entire production process.

oneBARRIER – recycle-ready flexible packaging

oneBARRIER represents one of the most exciting milestones in the journey toward truly sustainable packaging – a family of new alternative and sustainable solutions. These include oneBARRIER PrimeCycle – polymer-based monomaterial substrates that are EVO and topcoat-free – and oneBARRIER FibreCycle – full fibre/paper-based monomaterial structures coated with functional layers that can be recycled in the existing paper wastestream. Both are viable replacements for metallized-polyester, non-recyclable substrates.

“The validity and viability of the oneBARRIER family of recycle-ready high-barrier substrates was firmly established in 2022, as they were converted and printed on real scale equipment,” explains Sara Alexander, marketing and communications mgr.-Flexible Packaging Industry at BOBST. “BOBST has worked closely with an ecosystem of leading industry partners to create recycle-ready monomaterial, high- and ultra-high-barrier, duplex and triplex substrates as an alternative to non-recyclable metallized packaging for packaging designers.”

The oneBARRIER PrimeCycle PE AlOx monomaterial has been certified by the German institute Cyclos-HTP (cyclos-HTP – Institut cyclos-HTP), with a recyclability level of 98%, which exceeds industry guidelines and is an extraordinary achievement for high-barrier films. The oneBARRIER FibreCycle AluBond structure has also recently been tested by the German PTS institute (Papiertechnische Stiftung: Fibre-based research & development | PTS Website (ptspaper.de) and has been assessed as recyclable.

“Making recycle-ready flexible packaging a reality for our converting customers has been a priority objective for BOBST,” says Sara. “It is a journey that reached a major milestone achievement last year. In 2023, we are continuing to work on other developments and structures in polymer- and fibre-based applications and will also intensify our collaborative R&D on the third type of sustainable packaging, namely compostable/biodegradable solutions. We will also continue to submit the oneBARRIER different structures for assessment and add certifications by independent certification institutes.”

One complete solution – dedicated workflows for seamless production

BOBST has announced the launch of One complete solution, portfolio of end-to-end workflows for seamless quality production, from application management guidance and production of functional substrates to prepress setup, printing, converting, quality control and services. As the needs of converters become more unique due to diverse market factors, One complete solution provides everything converters need, tailored to their specific needs.

“The One complete solution for the production of the oneBARRIER FibreCycle recycle-ready substrate is a good example,” explains Sara. “The solution comprises the Expert K5 vacuum metallizer for deposition of AlOx or AluBond and the oneBARRIER Expert Coater for the primer and topcoating processes. It is everything the converter needs.”

The advantages for converters of having integrated equipment for production through One complete solution are manifold. These include integrated package solutions delivering process-machine-output in one flow; in this case, guaranteed barrier properties of the full structures (pre-coat + metallization + post-coat + eventually lamination, printing); knowledge of all technologies – coating, vacuum metallizing, gravure printing, flexo printing from narrow- to ultra-wide web, lamination equipment and processes from a single supplier; and different kinds of raw material specifications, coatings, adhesive chemicals and inks.

“Through oneBARRIER and One complete solution, BOBST is adding to its comprehensive portfolio of end-to-end solutions to help converters achieve complete and seamless quality production for more sustainable and productive flexible packaging,” concludes Sara.

Education member Central Piedmont Community College (CPCC) Hosts the 2023 High School Phoenix Challenge

On March 22-24, the 2023 Phoenix Challenge High School Flexographic Skills Competition, organized by the Phoenix Challenge Foundation (PCF), was held at CPCC in Charlotte, NC, in the Harper Campus graphics and printing labs.

The competition includes skills and testing on press operation (2-color job), prepress, platemaking, FTA Level One Certification, and a printing-related math skills test. ARC members Harper Corporation, SGS (Southern Graphics) and Sun Chemical always step up to provide judges and presentation to teachers. In addition to the five-element competition, the students and teachers receive hands-on ink training including mixing and proofing to match a Pantone color. This year we had 11 (two-member) teams from five states. The winner was Career Technical Center of Lackawanna County PA. High School Program — Phoenix Challenge Foundation

We want to thank CCL-Label and Evelyn Cruz for hosting tours with the students and teachers from the Phoenix Challenge to view label production first-hand. Seeing the multi-process printing operation is a great plus while they are in Charlotte.

Education member Central Piedmont Community College (CPCC) Hosts Palisades High School Graphics Field Trip

The PHS students and teachers were able to tour the CPCC Harper Campus Graphic Arts and Image Technology (GAIT) labs while the Phoenix Challenge High School Flexo Competition was taking place. The field trip had two major purposes: First was to introduce the students to the Phoenix Challenge Foundation High School Flexo Challenge. This provides incentive to the class to put together a team to compete in the 2024 Phoenix Challenge. The second purpose was to introduce students to the graphic industry and its career opportunities. Printing industry association representatives Jeff Stoudt of PICA, Dale Coates of TLMI, Robb Firming of FTA, Caitlin Salaverria of ICPF, Tony Donato of ARC, and Bettylyn Krafft of PCF all addressed the students’ questions on career possibilities.

Aaron D. Freeman, Palisades High School, CTE HS Graphics & Digital Design, Web Development Instructor, commented that the 19 students found the field trip was eye-opening to an industry they were unaware of. They were also excited to learn of the GAIT-available training at Central Piedmont Community College and the numerous industry scholarships.

Following are pictures from the March 23 field trip.

On April 6, CCL-Label Charlotte NC hosts Advanced Manufacturing Engineering Class of Olympic High School

Eighteen students and faculty members were able to tour the CCL-Label facility. Matthew Wykoff, Academy of Engineering NBCT instructor, was very impressed and did not realize the technology and engineering disciplines needed to produce roll-to-roll labels. The students were able to see first-hand the career potential in the printing/converting industry.

Seeing the technology and cleanliness when touring CCL’s fleet of 18 R2R label presses left a lasting impression on the students. This tour is part of the effort of Evelyn Cruz, operations director, to have CCL-Label become involved in the local educational community to engage students with awareness of the careers available in printing/converting. Cruz gave a PPT presentation reviewing the printing processes the attendees saw during the tour and where they learned about CCL and its 204 worldwide facilities.

Jim Garvey, chair of the GAA Committee, commends CCL-Label and Evelyn Cruz for reaching out to the next generation that will be joining the workforce and promoting careers in printing and converting. Jim encourages all members to get engaged with your local community to help promote our industry.

Lou DeFlaviis GAA Chair 2019-2022: Gives his farewell words of wisdom.

Lou DeFlaviis GAA Chair 2019-2022:
Gives his farewell words of wisdom.

To my fellow colleagues:

I would like to thank everyone for the continued support of the AIMCAL organization. I also would like to thank Tony Donato for his unending support during the process, and as he continues to keep things moving forward… As we searched for a way to keep the Gravure association alive. It was important to choose the best fit, and merge with an organization that supports the process and supports the membership. It was a very difficult but rewarding experience, to combine the two organizations for continued support and growth of the Gravure process. AIMCAL was chosen as the most logical, as many of the current members at the time employed the gravure process.

I would like to also thank Chris Kerscher and the AIMCAL group, as he and the others were instrumental in the process of combining the two organizations. I also want to thank Phil Pimlott; without his help and knowledge we would not be where we are today and was extremely essential to putting the two organizations together.

The road has been long but rewarding. I have been involved with the PLGA and GAA for many years. It was in 2013 under the leadership of Phil Pimlott that both organizations joined forces and merged to strengthen and support the Gravure process. This led to the creation of the Gravure Association of the Americas. The consolidation of the two organizations was long overdue and necessary. In 2019 I took over the leadership role from Frank Passarelli, little did I know the COVID Pandemic was around the corner. The Pandemic put the GAA into survival mode and I appreciate all those who rallied to keep the Gravure Association alive for another day.

As we fast forward to today, it was recognized in 2020 that a strong partner was needed to keep the vision alive. When we spoke to AIMCAL it was evident that this organization utilizes the process and would be a great fit to keeping the Gravure vision and process alive and as of August 1st 2021 the GAA merged into AIMCAL and became the Gravure AIMCAL Alliance Committee.

Over the years I have had the pleasure of working together with many of the members. I would like to thank everyone for the past, present, and future support of the organization. As they say, time does fly. Wishing everyone the best!

I am planning to officially retire effective May 1, 2023 and start a new career.

Please be safe and be well.

Best wishes to all.

March Technology Featured Article

Guest Author:

Alan Rogers

Polymount USA

Alan Rogers introduced the “Film Cleaner” machine at the 2021 R2R in the Gravure Track and the following article from Alan Rogers explains the “Film Cleaner” has truly helped those concern with sustainability and reducing printed film wastes from water or solvent based ink as it has been adapted by more printer/converters.

In today’s post-pandemic world, plastic prices have skyrocketed and printers are looking for new ways to reduce waste to offset these higher prices. In addition, most converters are busier than they have ever been so the increase in production also increases their waste numbers. Sustainability has become a very important aspect of our global society and printers today are working to reduce their carbon footprint, reduce waste, and recycle more than ever. However, no matter how hard we work on our sustainability program, there always seems to be leftover waste in the form of plastics that prevent you from achieving your goals. One of the biggest areas of waste for flexible packaging printers is make-ready film. Setting up a job can be costly, especially when several thousand feet of the film is used to match color and registration and then sent to the corner to collect dust after set-up is complete.

Once color and registration are in check, the job is run and the start-up material goes to waste as it can no longer be used due to the ink and mis-prints on the film. But what if you could re-use that film?

What if there were a way to “erase” the ink so you could set-up another job with the same film? Even if you don’t want to re-use the “clean” film for additional start-ups, you can choose to recycle it instead. Clean film with no ink will obtain a higher resale value compared to printed film.

Some converters are choosing a third option, which enables them to save money and eliminate their waste 100%. After cleaning the ink off of the film, they are re-granulating it back into pellets and adding it to virgin pellets when extruding new film.

This allows them to be 100% sustainable when it comes to managing their plastics inside their plant. How is this possible? Polymount International, creators of reusable solutions, has developed the first machine that can remove ink from your printed film. Instead of ending up with thousands, even millions of pounds of waste, the Polymount “Film Cleaner” removes the ink from printed film at a rate of as much as 100mteres/ minute and enables you to reuse your make-ready film over and over again! This machine is a gamechanger for the flexible packaging industry and will become a staple inside every converter in the next several years.

How does it work? It’s simple. The roll of printed film is guided through the machine via multiple loops and tension bars through a tank filled with a specialty developed Polywash cleaning liquid. Special microfiber brushes scrub the film, gently removing the ink. The pigment is filtered through a crossflow filtration system, dumping the dried pigment in a tote (recommend to run TCLP, the Toxicity Characteristic Leaching Procedure (TCLP), which is used for determining whether a solid waste is a hazardous waste) and then the remaining Polywash liquid is pumped back into the machine for re-use. The last station is where the film is rinsed and dried with a patented technology, the end result is a roll of clean film which is ready for the next set-up, or re-granulated for re-extrusion.

As much as the film cleaner provides savings by re-using their film, many printers have taken the stand that the sustainability revolving around this machine is the more important message. Their message to their customers is we are a sustainable company and cleaning our make-ready film for re-use drives that message home, which is important to many CGC’s (Consumer Goods Companies) in today’s environment. Many sustainability programs cost money, whereas this one, saves money. With ROI’s less than a year in most cases, cleaning film for re-use reduces waste, saves money and allows printers to achieve their sustainability goals. A win-win-win situation!

CCL-Label Charlotte NC hosted a tour for the Southern Piedmont Chapter 182 of SME on March 8th

SME always seeks manufacturing facilities to show their members the variety of products manufactured in their communities. 18 members and quests were dazzled at the technology and cleanliness they saw when touring CCL’s fleet of 18 roll to roll label presses. Before the tour, Evelyn Cruz the Director of Operations, presented a PPT where the attendees learned about CCL and its 204 worldwide facilities.

The PPT presentation was an overview explaining all the printing technologies that can be used by CCL in producing labels. There were sample flexo plates, a gravure cylinder, an Off-set plate and an imaged screen to illustrate the different ways the artwork was delivered to the substrates. The SME members all agreed CCL is a true manufacturer like any company making components.

Chapter 182 wants to thank Evelyn Cruz and Bradley Williams for being hosts and guides.

Waste Management Specialist – Senior
State of Wisconsin
Department of Natural Resources

Waste Determinations: The Cornerstone of Hazardous Waste Compliance

“Accurate waste determinations are the cornerstone of proper waste management. If a hazardous waste is misclassified as non-hazardous, a host of regulatory issues ensues.” According to Mike Ellenbecker, Hazardous Waste Program Coordinator with the State of Wisconsin Department of Natural Resources, the foundation on which hazardous waste compliance is built consists of a thorough understanding of generated waste streams. Depending on the nature of the hazards, mischaracterizing a waste stream can result in superficial to catastrophic failures. The most devastating outcomes can result in the loss of life or irreparable damage to the environment.
The waste determination process is also compromised when non-hazardous waste is mistakenly identified as hazardous. Gary Jones, Director of Environmental Health and Safety (EHS) Affairs at Printing United Alliance, explains “Improperly classifying non-hazardous waste as hazardous can create regulatory burdens that are unnecessary and costly.”
If a company has never experienced an unannounced hazardous waste compliance inspection the prospect may seem daunting, but these inspections follow a predictable path that can provide the company with an opportunity to evaluate and improve their waste management efforts. During an inspection, department compliance specialists examine waste streams and the associated waste determinations to ensure that hazardous waste is properly characterized, handled, accumulated, transported, treated, and disposed of. When a company’s waste determination process is flawed, it can lead to areas of non-compliance and in some cases, enforcement actions. To strengthen your waste management program, it is valuable to have an awareness of both the common stumbling blocks that businesses experience and a knowledge of the available resources.
To protect both workers and the environment, the hazards of each generated waste must be well understood and communicated. Companies that rely solely on the expertise of third parties such as consultants, brokers, transporters or treatment, storage and disposal facilities (TSDFs) run the risk of waste mischaracterization and potential compliance issues as the regulatory responsibility for waste determinations resides solely with the generator. Companies should not assume that their waste hauler or TSDFs test every hazardous waste stream or that these third parties can identify unknown hazards. Often, TSDFs only test parts of incoming loads for limited parameters or characteristics. This disconnect can create hazardous conditions for the generator, the transporter and the TSDF.
For example, a facility may assume their Flexo Computer-to-Plate printing operations are ecofriendly and do not generate hazardous waste. This presumption fails to consider the plate development process that generates a waste stream with a pH above 12.5, making it a corrosive hazardous waste. Conversely, a printing operation that switches to a wash solvent with a flashpoint above 140°F may continue to refer to an outdated waste determination that characterizes the spent solvent as ignitable (i.e., flashpoint below 140°F). This mischaracterization of waste can affect a hazardous waste generator’s regulatory status. Over-classification of waste as hazardous could result in a facility operating under more regulatory requirements than necessary while under-classification could result in a facility not operating in compliance with the required regulation of their actual generator status, not to mention creating hazards for workers and others. A thorough understanding of the waste determination process is the first step in building a structurally sound waste management program.
There are five key steps in the waste determination process which include:
Identify all waste streams.
Determine whether each waste stream is a solid waste.
Determine if each solid waste is excluded from regulation as a hazardous waste.
Determine whether each solid waste is a hazardous waste.
Document the information and decisions made in steps 1-4.
The waste determination process falters when any of the steps are skipped or misinterpreted. Early in the determination process, confusion about what meets the definition of a solid waste can lead to an incorrect waste determination. This step is important because if the material in question is not solid waste, it cannot be hazardous waste. Note that the definition of solid waste does not refer to the physical form of the waste. A “solid” waste can be a solid, liquid or containerized gas.
Another challenge can arise when researching the hazards of a waste by relying on Safety Data Sheets (SDS). For example, while conducting a waste determination for a spent developer, the SDS for the developer is reviewed. The SDS indicates that the pH of the developer is 13. With this information, the printing operation assumes that the spent developer also has a pH above 12.5, and the spent developer is characterized as a corrosive hazardous waste. This determination process fails to consider that the pH of the spent developer may be lower than the pH identified on the SDS for the unused product. When using a calibrated pH meter to conduct representative sampling it is discovered that the pH of the spent developer is below 12.5. In fact, this waste stream is not a corrosive hazardous waste.
Keeping waste determinations up-to-date is challenging when process changes that can affect the waste streams are not evaluated or documented well. When contemplating a change, a best management practice would be to keep the person responsible for compliance in the loop to ensure that waste determinations continue to be accurate. For example, if the pressroom elects to switch to a solvent wash with a lower flashpoint, the possible health and safety implications need to be weighed prior to the change and a waste determination will need to occur that takes the change into account. It is difficult to implement a successful a waste management program when waste streams change or emerge without the knowledge of compliance personnel.
To strengthen the waste determination process, there are several resources available. For a detailed discussion of the waste determination and recordkeeping process, refer to the guidance document: Waste Determinations & Recordkeeping (wi.gov) A detailed resource for printing operations continues to be the Printers | | Wisconsin DNR , which outlines environmental compliance and sustainability resources specific to the printing industry. A recent addition to the portal includes a fillable waste determination checklist. While completion of the checklist is not a regulatory requirement, it provides a helpful tool to clearly document and communicate the determinations for each waste stream. Additionally, it is recommended that facilities retain the evaluation and associated documents for all waste determinations regardless of whether the waste is determined to be hazardous or non-hazardous.
An accurate and complete set of waste determinations provides a solid foundation for the proper management of hazardous waste, and the correct identification of the applicable requirements. Facilities enjoy the benefits of improved occupational safety and environmental health outcomes, and the resulting efficiencies provide cost savings.

Going forward from the February 2023 issue of EPA’s Asbestos and Small Business Ombudsman’s (ASBO) monthly bulletin, the SmallBiz@EPA will feature a new look and email delivery method that we’re very excited about. The new ASBO bulletin will make it easier for you to learn about EPA’s events, rulemakings, trainings, and other environmental information of interest to the small business community. These improvements are in response to the readership feedback shared with us.
The updated bulletin will be delivered to your email inbox via Mailchimp, an HTML-based email delivery service. You’ll see the full newsletter right in the body of the email, so no more clicking on a PDF to read each issue. Each issue should resize automatically based on the device you’re using to read it, making it easier to read articles on your phone. And using Mailchimp will allow you to manage your own subscription preferences.
To ensure that the bulletin reaches your inbox each month we are asking that you add the ASBO email address, asbo@epa.gov, to your email contacts. This should alert your email software that this is from a trusted email contact and not an unwanted spam message.
