It is often said that we live in the plastics age. Plastics are consumed across all sectors (clothing, medicine, construction, food packaging, etc.) as plastics are versatile, low cost, and easy to manufacture (Singh et al., 2017). However, the final disposal of plastics is a global concern. If plastics leak into the environment, some microplastic could break away from larger plastic products, and move through air and water systems, finding their way into the food chain and posing risks to biodiversity, food availability, and human health (Li et al., 2016). One of the main priorities of governments and cities across the globe is to address these issues by reducing the production of virgin plastics and limiting the generation of waste plastics through recycling. The current plastic recycling industry is primarily based on mechanical recycling of rigid and clean materials that are easier to process such as beverage bottles (made from polyethylene terephthalate, PET), and milk jugs (made from high density polyethylene, HDPE). Most plastic materials, however, are contaminated with other plastics, dyes/inks, fillers, and other materials. Mechanical recycling often does not produce high quality plastics from these contaminated materials, which is the case for most flexible packaging containers (Al-Salem et al., 2009). Flexible plastics, like plastic bags, account for over 35 % of the plastics produced in 2015 (UNEP, 2018) and are the most used material for packaging globally (Figure 1). Unfortunately, flexible plastic materials usually end up in open dumps, landfills, or are incinerated after use since they cannot be easily mechanically recycled, resulting in a series of cascading environmental impacts. Figure 1 shows the breakdown of packaging by material type detailing the demand of rigid and flexible plastic packaging.
Figure 1. Global demand of packaging materials in 2019 (adjusted from Statista, (2022)) detailing the demand of rigid plastic packaging (for 2017 based on Ceresana, (2019)) and flexible plastic packaging (for 2017 based on Grand View Research, (2018)).
Plastic packaging materials, in the form of multilayer films, are mixtures of several and different plastic layers which are combined to achieve specific properties that cannot be provided by single plastic layers. Combining different layers of plastics results in stronger and impermeable materials with unique properties that help preserve food quality and lifetime (Figure 2). The multilayer packaging materials allow less material to be used which reduces greenhouse gas emissions. These multilayer plastics can also help reduce food waste through smaller portion packaging that can be consumed more efficiently. The properties of these multilayer films cannot be achieved with one single plastic material. The advantages of multilayer films are numerous, but multilayer plastics cannot be mechanically recycled easily because the different layers are chemically incompatible. One promising technology to effectively recover these layers is known as solvent-targeted recovery and precipitation (STRAP), which breaks down multilayer films into their original plastic building blocks (Walker et al., 2020).

Recycling Plastic Films through STRAP Technology Basics
Multilayer films are among the most challenging plastic wastes to recycle, but the STRAP technology can recover the individual plastic components in multilayer plastic materials. In general terms, STRAP “washes” multilayered films several times with solvents to separate the multiple components mixed in plastic films into single components, known as resins (Figure 3). These resins can then be reused to make more of the product from which they originated, or they can be used to manufacture products with higher value or quality (known as upcycling). There are different multilayer materials that can be processed with STRAP including clear rigid multilayer films used in food containers, printed multilayer films used for food packaging, mixed multilayer plastic waste, disposable face masks, and other plastic waste collected along with municipal solid waste (MSW). For more information on the technical details of the STRAP process, the reader can refer to (Walker et al., 2020).
Figure 3. Production of single layer films from multilayer films through STRAP.
Showing the Scalability of STRAP
The current limitation of STRAP is that our process only produces small quantities of final material, less than 0.11 kilograms (0.25 pounds) per week. To make this technology commercially viable, larger quantities of materials that plastics converters require in production need to be manufactured. To demonstrate the STRAP technology at a larger scale, a process development unit (PDU) was designed and tested to produce 25 kilograms (55 pounds) per hour of recycled resins from waste flexible and rigid plastics. Figure 4 shows a simplified STRAP diagram featuring the recovery of high purity plastic resins from mixed plastic waste or flexible plastics.
Figure 4. Simplified STRAP process flow diagram.
The first step in the STRAP process is to shred the as-received mixed plastic waste into smaller size particles that are uniform and small/light enough to move continuously and steadily (or flow) in the reactor tanks. After shredding, the smaller plastic particles are fed into a specially designed-dissolution tank. A solvent selectively dissolves a targeted plastic from the mixture. The dissolved plastic (liquid/slurry form) and non-dissolved plastic (solid form) are separated using filtration. The non-dissolved plastic is transferred to a solvent recovery system while the dissolved plastic is pumped into a precipitator. In the precipitator, the solvent is cooled, and the plastic precipitates; that is, it turns into a solid. The plastic is then sent to a solvent recovery system for a second time. The solvent is completely recovered and re-used in the process. The recovered plastic is then extruded into pellets and sold to plastic convertors. The amount of solvent in the pellet is controlled during the drying and extrusion processes.
Economics and Environmental Benefits of STRAP
The STRAP process can produce high quality resins at costs comparable to the virgin resins, according to detailed process models based on our experimental data. The STRAP process has 60 to 70 percent lower greenhouse gas (GHG) emissions than producing the virgin polymer. Figure 4 shows the emissions to recover polyethylene via STRAP from a multilayer food packaging film vs emissions of virgin packaging made from petroleum. All energy (electricity, steam, natural gas, etc.) and material (e.g., water, solvents, other chemicals) inputs were evaluated from extraction of raw materials to production of polyethylene at the plant for both polyethylene products (STRAP vs petroleum). Figure 4 shows that the total GHGs of extracting polyethylene via the STRAP process (0.7 kilograms of carbon dioxide equivalents per kilogram of polyethylene) are 68% lower than the impacts of producing polyethylene from fossil sources (2.2 kilograms of carbon dioxide equivalents per kilogram of polyethylene).
Figure 5. Climate change impacts from the STRAP process and the production of polyethylene (PE) from fossil fuels.
There are several other environmental benefits from STRAP. These include eliminating undesirable end-of-life scenarios like disposal of mixed plastic waste in landfills, incineration, creation of micro and nano plastic contaminants, and pollution of oceans.
Initiatives to Install the First STRAP Commercial Plant
The Green Bay and Northeastern Wisconsin area is a major hub for flexible packaging, label production, printing, and associated plastics industries and constitutes a natural location to develop the first STRAP commercial plant . Wisconsin ranks 8th in the nation in terms of plastics industry employment with over 43,000 people working in this sector and a direct plastic’s payroll of US$2.3 billion. This leadership is even higher (3rd in the nation) for flexible packaging products with over 25,000 people currently employed with projected 9% growth in the next 10 years (Plastics Industry Association, 2023). For example, Amcor, one of the largest packaging companies in the world, has 17 facilities in Wisconsin. Many companies in the food industry use plastic products, which generate billions of dollars annually. In addition, there are numerous local, national, and international manufacturing companies in Northeastern Wisconsin that make equipment to support the plastic and flexible packaging industries. As a leader in both production and consumption of flexible packaging products, Wisconsin has an enormous potential to host the first STRAP commercial plant, maximizing the efficiency in terms of material availability and transport of waste plastic multilayer films and recovered resins. Moreover, the University of Wisconsin-Madison and the University of Wisconsin-Stout have well-established programs in plastics and packaging and are currently doing outstanding research in plastics and STRAP.
Summary
Plastic waste generation has been increasing over the years, as the recycling rate for plastics is low compared to other materials. Moreover, conventional mechanical recycling methods are not technically or economically feasible for many multilayered plastic films, which are the main materials used for food packaging. The solvent-targeted recovery and precipitation (STRAP) technology breaks down the mixed plastic waste and recovers high-quality pure plastic resins. STRAP can process various types of plastic wastes including printed multilayer films used for food packaging, mixed multilayer plastic waste, disposable face masks, and other plastic waste collected along with municipal solid waste. A process development unit is being built to demonstrate this technology at a larger scale.
The STRAP process can economically recover polyethylene from multi-layer film waste at scale.
The environmental analysis shows that the recovery of polyethylene via the STRAP process generates fewer greenhouse gas emissions than the production of virgin polyethylene from petroleum.

The Center for Chemical Upcycling of Waste Plastics (www.cuwp.org) is developing a technology that allows the recycling of flexible and rigid multilayer and mixed plastic wastes.
This technology is called solvent-targeted recovery and precipitation or STRAP. STRAP uses non-toxic solvents to produce food-grade resins from previously unrecyclable materials. STRAP has been demonstrated in the laboratory and is now being scaled up. A larger 25 kg/hr pilot system is being built at Michigan Tech University and will be complete at the end of 2023. We are working with several Wisconsin plastic converters (Amcor, CNG, ePac, Placon and others) to convert their plastic wastes into high quality resins. The pilot system will provide enough material to plastic converters to qualify them in several applications. After we successfully operate the pilot system we hope to design the first commercial facility in Green Bay, WI. This facility will produce high-quality PE and PP resins from plastic wastes and sell them back to plastic converters.

Inefficient actions throughout the papermaking process can result in a shorter life for your equipment, increase changeover times, and decrease speed, capacity, and productivity.
Addressing these inefficiencies by optimizing your line can help lower operating costs, reduce waste, shorten lead times, and improve your operation’s safety and working conditions.
Common Challenges in Pulp & Paper
Web handling and paper defects can lead to emergency stops and off-spec product rolls. Web tension and speed differentials in the winder and the paper machine can help identify flaws, while live measurements ensure moisture, basis weight, and thickness are within range.
Bottlenecks can limit the paper machine’s and winder’s overall production capacity. Slowdowns and limitations must be identified through analyzing machine data and managed with automation technology, innovative design, and replacement of legacy equipment where necessary.
Mitigating hazards by implementing changes that meet industry standards, automating hazardous functions, and adding safety features like guarding, fencing, and safety controls can minimize personnel risks and reduce exposure to liability issues while improving production capacity.
Paper Mill – Pulping department
Automated Controls for Better Efficiency
A paper manufacturer wanted to upgrade its process to include automation technology. Their machine required maintenance personnel to adjust the valves manually, and the customer wanted to reduce worker interaction and improve the consistency of their production lines.
The first step was to audit the existing controls. Then, we designed an automated control system and acquired the instrumentation and control devices. Lastly, we developed the control software and provided a SCADA system. The customer can now have a single operator control the paper machine through the visualization system and reduce their raw material consumption by ensuring a more consistent paper grade.
75-Year-Old Equipment Gets an Upgrade
A paper mill in the midwest specializes in limited runs that require frequent grade changes. The original paper machine is more than 75 years old, and market demands meant searching for more viable methods for controlling the speed of the machine and its various sections.
Quad Plus engineers started by thoroughly analyzing existing equipment and carefully considering the paper mill’s customers. Our solution included sectionalizing the drives and installing an AC-coordinated drive lineup. We then provided a system to regulate the speed of the entire machine and its various sections. For additional safety, we added safety-rated VFDs, safety processors, and an additional I/O.
Automating the line allows the current crew to focus on value-added areas rather than operations. The younger, less experienced workforce can come on board as automation helps with the overall burden of training. Lastly, the new line shaft and DC motor will need less maintenance so the mill can enjoy less downtime.
Meeting Market Demands
For most manufacturers, the market determines how to manage operations. When the customer demands outpace the capabilities of your equipment, it’s time for a change. Automation technology is the answer to a more efficient production process, no matter your industry.

Thanks to dazzling artwork and the latest in science and technology – from the extruder to the printer to the laminator, today’s packaging film is eye-catching and durable.
It’s stunningly beautiful. And expensive.
In fact, by the time the parent roll gets to the converting machine to be made into pre-made pouches, it is at the most expensive point in the ‘film-making’ process.
As much of that valuable film as possible needs to end up as a successful package -and as little as possible in the scrap bin.
“Pouch converting technology has come a long way to preserve the investment that brand owners make in the materials which ultimately must protect and promote their products,” says Scott Fuller, Pouch Equipment Product Line Manager for CMD.
Here are 5 suggestions to utilize that technology to get the best overall efficiency and least amount of waste in your pre-made pouch converting process.
1.) Choose machines that utilize a shorter footprint and reduced web path – this results in less material needed at thread-up, better web control and less waste. “Pouch machines have historically been very long,” says Fuller “Threading up the entire length of a 50 or 60 foot machine uses a lot of film, and when adjustments are made at the back of the machine, a lot of material can be wasted waiting for the adjustment to work its way to the front”. Reducing the machine length and shortening the web path, allows for better web control and more efficient adjustments. “This makes so much sense that CMD reduced the overall length of our 760-SUP machine by 11 feet, and the web-path by over 20 feet” adds Fuller.
2.) Insist that the pouch system your pouches are converted on is easy to use so operators can competently dial in recipes for fewer mistakes, waste and downtime.
“After years of consulting with customers, partnering in SMED events and collecting data, it became very clear that the amount of waste associated with difficult-to dial-in-systems was much higher than originally estimated,” says Fuller.
Today’s machines offer sophisticated controls systems that are capable of automating much of the process. “The unresolved step was not the capability of the machinery; rather, it was a matter of refining why, and how the operator needed to interact with the machine.” notes Fuller, adding that simplifying the process and incorporating ease-of-use concepts were critical to closing this gap.
“The updated design of our stand-up pouch system focused on simple, fool-proof adjustments throughout the machine, and intuitive touch screen controls with data-rich reports to predict and prevent downtime,” says Fuller. He notes that the system includes an on-board standard operating condition (SOC) worksheet that can be used to pre-set the machine so very little film is wasted at changeover.
3.) Your system should have robust sealing technology with a wide operating window and a methodology to confirm that the pouches you produce are not only beautiful, but strong, with no leakers. “With today’s technology, there is no reason you can’t have verifiable data on your pouch quality, and with the price of the film being converted, it makes good sense to expect it,” says Fuller. Data acquisition and IoT has evolved to produce real-time reporting, and powerful KPI dashboards that can be accessed on the machine or remotely.
4.) A reliable system will consistently produce the same quality on each pouch in your production run – resulting in less waste and fewer complaints on final package quality. “The reliability factor is huge,” says Fuller. “Your pouch machine should consistently produce the same results, without the need for constant minding or excessive readjustment.” Relying on the system to produce the same quality, pouch after pouch, means you can also rely on fewer adjustments and less waste.
5.) A system designed with flexibility in mind is helpful to add the finishes and function that today’s convenience-conscious consumers demand – easy open/close, sturdy stand up properties for shelf appeal, etc… The pouch converting system should be designed to easily add the tooling needed for these extras.
“While most pouch systems are designed to add these capabilities, finding one with a design that flexibly moves tooling in and out while retaining robust process stability, is the best choice for consistent quality and less waste.
Much is invested in producing the perfect aesthetics for your packaging. Utilizing ever-improving converting technologies to ensure the most efficient use of that investment is a wise strategy for growth and success.
