Resources for Recycling Expanded Polystyrene

Expanded polystyrene, or EPS, is a lightweight, closed-cell plastic foam used in a variety of products, including coolers, insulated beverage cups, takeout containers, building insulation, etc. This differs from extruded polystyrene (XPS), which is typically formed into rigid panels used for building insulation, mainly in terms of how it is manufactured, but also in terms of thermal protection, moisture resistance, and strength. Styrofoam is a brand name of XPS insulation manufactured by DuPont. Despite these differences, the similar products have become synonymous in the minds of most people, and just as certain brand names for facial tissue and bandages eventually became the common terms for those products, most people refer to EPS products as “Styrofoam.” In this blog post, when you read “EPS” or “expanded polystyrene,” know that this refers to the materials you likely think of as “Styrofoam” packaging–though DuPont would be quick to point out they’re not the same thing!

For several years, departments at the University of Illinois at Urbana-Champaign have been encouraged to recycle EPS at a drop-off location just outside the Dart Container plant in Urbana, IL. Recycling EPS is often not economically feasible basically because foam packaging is mostly air, and the fuel needed to ship large amounts of the bulky, lightweight material for processing would often not be offset by money obtained by selling it. Dart manufactures EPS products however, and thus, accepting and recycling it is in line with a sense of extended producer responsibility for the management of those products at their end-of-life, especially since EPS pollution famously takes hundreds of years to break down in the environment. The Urbana Dart plant used equipment to heat, extrude, and compress foam packaging into blocks of material that could be used for products such as picture frames, surfboards, or park benches. This YouTube video shows a similar operation in a California plant.

Earlier this year, however, Dart unfortunately announced that the Urbana plant would be closing by the end of 2023. While this is tragic mainly due to the loss of jobs and the potential blow to the local economy, it also means the loss of an outlet many people relied upon to keep EPS packaging out of the landfill. In fact, the City of Champaign ‘Where Do I Recycle It?’ resource reports that Dart closed their Styrofoam drop-off center in Urbana on Friday, September 29, 2023.

Obviously, the best approach, even before the sad news about Dart’s Urbana plant was announced, has always been to avoid EPS products whenever possible precisely because of the difficulties in recycling the material. But avoidance isn’t always possible for consumers, especially since EPS is so widely used in food and beverage packaging, to protect breakable products, and to regulate the temperature of various items during shipping—including items intended for laboratories. So, while alternatives are important to explore (and might be the subject of a future post), this post focuses on options that might help people in Champaign County divert EPS in the near term. Although the inspiration for this post is the change in opportunities to recycle EPS locally, many of the options below are applicable in other parts of the state or U.S.

Other foam drop-off sites (for those not in Champaign County)

To be clear, Dart is not going out of business or closing all its facilities, and the company does still offer public drop-off EPS collection points at various places in the U.S., including elsewhere in IL—just not in the Champaign-Urbana area anymore. To find out whether there’s a Dart public drop-off near you, visit https://www.dartcontainer.com/why-dart/sustainability/foam-recycling and search their map.

The Food Service Packaging Institute’s website includes a map showing EPS foam recycling drop-off sites throughout the U.S. and includes some basic information about foam recycling. See https://www.recyclefoam.org/about-foam-recycling to learn more and to search for a drop-off near you.

Dart’s Next Life Program

Besides their public drop-off collections, in April 2023 Dart also announced a mail-in product take back program called Next Life. This program is restricted to Dart brand products, but it is not restricted to EPS—Dart packaging made from paper (specifically from the Bare by Solo brand), polyethylene terephthalate (PET, #1), polypropylene (PP, #5) and expanded polystyrene (#6 foam) are all acceptable products. This program is not free, or particularly easy, however. To participate, consumers can visit https://take-back.dartcontainer.com/ and indicate which of these three packaging categories they’re interested in recycling. Then “proof of purchase” images must be uploaded, which might be in the form of scanned store receipts, invoices, or product photos. Once the images are uploaded, the consumer must then purchase a “discounted shipping label” by paying for flat rate shipping for the material ($9 for a maximum box size of 20″ x 30″ x 11” when the process was tested during the writing of this post). The purchased label can be printed out and used to ship the items back to Dart.

While this is better than nothing, the process is convoluted and inconvenient for consumers and is restricted to Dart products. Only die-hard individual environmental advocates, or organizations and businesses committed to zero waste, are likely to jump through the necessary hoops and pay to participate. Coupled with efforts to reduce relevant types of waste or avoid them altogether, this program can help keep some remaining unavoidable packaging out of landfills, so it’s worth keeping in mind.

Terracycle Zero Waste Box

If your organization or business generates a fair amount of EPS waste, you may wish to consider Terracycle’s “Styrofoam – Zero Waste Box™” as an option for recycling all sorts of EPS food packaging and shipping waste, so long as there is no food or other organics contamination on the foam. You buy a collection box with a pre-paid shipping label, seal it when full and send it back to Terracycle. This is very convenient but expensive—the box comes in three size options, with the smallest (11”x 11” x 20”)  costing $107. There are discounts for purchasing collection boxes in bulk (15+).

Packing Peanuts (Loose Fill)

EPS foam packing peanuts (aka loose fill packaging) were never accepted as part of Dart’s public recycling drop-off in Urbana. Local shipping businesses may accept them for reuse, however, as long as they’re clean and dry. It’s always advisable to call these companies first to confirm they will accept these before taking any to their location. The City of Champaign “Where Do I Recycle” page suggests contacting the UPS Store on Marketview Drive in Champaign, or CU Pack N Ship (formerly Mail & Parcel Plus). Note that the foam recycling map at https://www.recyclefoam.org/about-foam-recycling, mentioned above, can be searched specifically for loose fill recycling options.

Polystyrene Coolers

Many local laboratories, including those on the University of Urbana-Champaign campus, receive materials in polystyrene coolers. Laboratories should keep in mind that Millipore Sigma has a polystyrene cooler return program for U.S. customers, which is relatively easy and free for the consumer. See https://www.sigmaaldrich.com/US/en/services/support/recycling/polystyrene-cooler-return-program for details.

Several sources related to laboratory waste recycling suggest that New England Biolabs (NEB) have a similar polystyrene cooler take-back program, but that information seems to be out of date because NEB no longer uses EPS coolers. NEB now ships its products in an alternative to EPS, called the ClimaCell® cooler, created in conjunction with TemperPack, which is 100% recyclable. See https://www.neb.com/en-us/tools-and-resources/video-library/introducing-the-neb-climacell-cooler to learn more. If your laboratory or other business ships items that require temperature control, you might consider contacting TemperPack for options that suit your needs. See https://www.temperpack.com/climacell/.

Corning Packaging Take Back

Laboratories should also be aware that Corning will take back all Corning®, Falcon®, or Axygen® product packaging—including EPS centrifuge tube racks. Other acceptable wastes include pipette tip boxes and plastic bags and peelable lidding film paper from cell culture dishes, plates, and flasks, #2 or #4 only. See https://corning.mailthisback.com/ for further details and to print a pre-paid shipping label.

Other Mail-Back Options

Finally, the EPS Industry Alliance has a list of mail-back options at https://static1.squarespace.com/static/62e5bccd5d8f2e718d48d121/t/643ff95d6ef7d36ad9920d25/1686167676074/EPS+Mail+Back+Locations.pdf. There are eight locations in the Midwest region, though none are in IL.

Hopefully, these resources will help you divert unavoidable EPS from landfills. Are you aware of other EPS recycling programs? Share your knowledge with our zero waste team at istc-zerowaste@illinois.edu.

Celebrate Plastic-Free July: Atypical tips to reduce your use of single-use plastics

Plastic Free July Badge

In a 2017 article in the journal Science Advances, researchers Roland Geyer, Jenna R. Jambeck, and Kara Lavender Law estimated that as of 2015 “approximately 6300 Mt of plastic waste had been generated, around 9% of which had been recycled, 12% was incinerated, and 79% was accumulated in landfills or the natural environment. If current production and waste management trends continue, roughly 12,000 Mt of plastic waste will be in landfills or in the natural environment by 2050.” With microplastics having been detected in virtually every habitat on Earth, including the ocean floor, and in a variety of organisms, including humans, it’s easy to understand why the U.S. Environmental Protection Agency (EPA) recently released a draft National Strategy to Prevent Plastic Pollution, as described in a previous post (Note: The deadline for the public comment period has been extended to July 31, 2023, so don’t miss out on the chance to read the strategy and provide feedback). It’s also easy to understand why delegates from nearly 180 countries came together in Paris recently, to discuss what would be the first legally binding global treaty to reduce plastic pollution. The first draft of that treaty is scheduled to be developed by November 2023, with a goal of having a final agreement in force by 2025.

For a dozen years now, people have taken time in July to consider ways they might help stem the tide of plastic pollution. Plastic Free July is an initiative of the Plastic Free Foundation which began in 2011 and has grown into a global movement to reduce single-use plastic consumption and pollution. You can sign up to take the Plastic Free July Challenge, and receive weekly emails in July to inspire and motivate your plastic reduction efforts. To help get you started the Plastic Free July website offers tips on ways to reduce single-use plastic. You can probably guess some of the tips which have become common mantras among those interested in waste reduction, such as using a refillable mug instead of accepting single-use coffee cups or bringing reusable bags when you go grocery shopping instead of packing your items home in plastic carrier bags. But the tips below might surprise you and inspire you to think about just how ubiquitous single-use plastic has become.

Note: ISTC does not endorse, either explicitly or implicitly, any particular manufacturer, vendor, product, or service. Information about specific products, manufacturers or vendors is provided for reference only.

  • Chew less gum and/or opt for plastic-free alternatives. It may surprise you to know that chewing gum, based on the indigenous tradition of chewing natural rubber called chicle, involves single-use plastic in its actual substance and not just in its packaging. According to the website Plastic Free Shopper, “Most modern chewing gums have what’s known as a gum base which makes up the majority of the chewing gum. This synthetic rubbery substance is commonly made from ingredients including: Butadiene-styrene rubber Isobutylene-isoprene copolymer (butyl rubber); Paraffin (via the Fischer-Tropsch process); Petroleum wax; Polyethylene; Polyisobutylene; Polyvinyl acetate. This synthetic plastic/rubber gum base is mixed with sweeteners and flavourings to make up regular chewing gum as we know it. Ingredients such as Polyethylene and Polyvinyl acetate are both common forms of plastic. Polyethylene is found in items such as plastic bottles and food containers, and Polyvinyl acetate is used in glues and adhesives.” So, when people spit their gum out on the sidewalk, they’re not just littering and setting the innocent up for sticky shoes–they’re also contributing to plastic pollution. If you enjoy chewing gum, a simple way to reduce your single-use plastic consumption is to opt for brands made with natural chicle, such as Simply Gum or Glee, among others.
  • Take plastic out of your water filtration equation. If you’re avoiding water in disposable plastic bottles, odds are you might be using a reusable bottle or pitcher with a filter. However, the more popular units for this purpose still incorporate plastic in the filters. In October 2022, editors of The Good Trade shared their top five plastic-free water filtration options. It should be noted that most of these are pretty pricey and the filter cartridges for the plastic-free vessels still tend to incorporate some small amount of plastic. But the Kishu charcoal stick option is quite affordable, completely plastic-free, and after its days as a water filter are over, the sticks can be composted, put out in your garden, or reused to absorb odors in your refrigerator.
  • Quit smoking—or encourage a friend or family member to do so if you’re a non-smoker. There are obvious health-related reasons to do this, but did you know that cigarette butts are the most common form of plastic pollution? A 2019 review article in Environmental Research explained that “Cigarette butts (CB) are the most frequent form of personal item found on beaches. Yearly, 6 trillion cigarettes are smoked worldwide, and 4.5 trillion cigarettes are littered in the environment.” Once they have become litter, cigarette butts degrade into microplastics. E-cigarettes and plastic vape cartridges also contribute to the plastic pollution problem, as well as contributing to the burgeoning tide of e-waste (that’s another post for another day). Learn more at “Plastics, the Environment, and the Tobacco Industry,” an online resource from the University of Bath.
  • Dispose of pet poo without plastics. If you have a dog, or a cat whose litter box needs to be scooped, disposable plastic bags are probably a commonly used tool. It’s definitely important to pick up your dog’s poo during a walk (see this article from The Guardian and this page from the Dooloop website for more on the environmental impacts of your best friend’s excrement), but there are ways to take care of this business with less petroleum-based plastic. The Dog People list their choices for plant-based pet waste bags that are “compostable under the right conditions.” If you have a yard with available space, you might also consider a separate compost pile or bin for pet waste (avoid using this compost on your fruit or vegetable garden to prevent the spread of parasites, but feel free to fertilize your flowers and other ornamental plants). Doogie Dooley offers in-ground digester systems for breaking down dog waste (they’re not compatible with cat waste, sadly), and though all incorporate plastic lids, there is a model with a steel tank. I Love a Clean San Diego also highlights some pooper scoopers and disposal tips that allow you to pick up waste without using a dedicated plastic bag.
  • Reduce your use of laser printers and copiers when possible. We all know that printer ink and toner cartridges contribute to the plastic waste stream, so many of us recycle our spent cartridges and purchase remanufactured ones to reduce consumption of virgin plastics. But did you ever stop to think about what laser printer and copier toner is made of? Spoiler alert—toner is mostly made of plastic. We’ve all seen reminders to print documents or emails only when necessary to save paper, but it turns out, this is a good tip to avoid plastic consumption too. If you’ve ever added shredded office paper or junk mail printed on non-slick paper to your compost bin, you might reconsider and put those in the paper recycling bin instead. Toner starts out as a collection of microplastics, so when that printed paper breaks down in a compost pile, you might be inadvertently releasing those into your environment. This Federal Electronics Challenge resource from the US EPA includes tips for reducing paper and ink usage. See this post from CDW on the differences between ink and toner, and you might also consider bio-based toner options available in your country. Some of these reduce the amount of petroleum-based plastic involved by using powder made from soybean oil. Some bio-based toners also use a percentage of bio-plastics for the cartridges themselves, such as https://pelikan-printing.com/biobased and https://www.union-tec.com/print-rite-bio-based-toner-cartridges/.

This post is already quite long, so we’ll stop at five tips, but there are many more ways to reduce single-use plastics. What are your favorites? Share your thoughts on social media.

Help #BeatPlasticPollution on World Environment Day June 5th

World Environment Day 2023 banner

World Environment Day (WED) is an annual event celebrated on June 5th which raises awareness of environmental issues and encourages people across the globe to take action to protect our shared environment. The United Nations (UN) General Assembly designated June 5th as World Environment Day in 1972, marking the first day of the Stockholm Conference on the Human Environment. That same day, they adopted another resolution creating the United Nations Environment Programme (UNEP). UNEP coordinated the first celebration of WED in 1973, and it has led celebrations ever since. This year’s theme is #BeatPlasticPollution, shining a light on this worldwide issue (see past themes at https://www.worldenvironmentday.global/about/history). This year’s host country is Côte d’Ivoire in partnership with the Netherlands. Since 2014, Côte d’Ivoire has banned the use of plastic bags, supporting a shift to reusable packaging, and the country’s largest city, Abidjan, has also become a hub for environmentally minded start-ups.

As described in a previous post, plastics, including micro- and nanoplastics, are ubiquitous in our environment, even leaking from plastic recycling facilities. Microplastics are found in a variety of organisms, including humans. Recognizing the need for action, the U.S. Environmental Protection Agency released a draft National Strategy to Prevent Plastic Pollution in April and is seeking public comment through June 16, 2023.

On its WED website, UNEP provides a Beat Plastic Pollution Practical Guide, with recommendations for individuals; non-governmental organizations, faith organizations, and community groups; science and education organizations; governments; cities, towns, and local authorities; investors; and businesses and industry. The guide outlines how plastic pollution affects us, the sources of plastic pollution, what progress is being made, and what more needs to be done to address the situation.

Cover page of UNEP "Turning off the Tap" reportThe WED website also links to an interactive lesson on the plastic pollution problem and the UNEP report, Turning off the Tap: How the world can end plastic pollution and create a circular economy, which was released on May 16, 2023. This report examines the economic and business models needed to address the impacts of the plastics economy. UNEP suggests “a systems change to address the causes of plastic pollution, combining reducing problematic and unnecessary plastic use with a market transformation towards circularity in plastics. This can be achieved by accelerating three key shifts – reuse, recycle, and reorient and diversify – and actions to deal with the legacy of plastic pollution.” They explain that “reorient and diversify” “refers to shifting the market towards sustainable plastic alternatives, which will require a shift in consumer demand, regulatory frameworks and costs.”

Finally, the WED site provides relevant news, updates related to this year’s celebration, an opportunity to register your organization’s relevant events or activities, and links to other UNEP reports related to the global plastic pollution problem.

What strategies do you use to reduce plastic consumption and pollution? Share your thoughts on social media this June 5th with the hashtag #BeatPlasticPollution. You can connect with UNEP on Facebook, Twitter, LinkedIn, or Instagram.

U.S. EPA seeks feedback on draft National Strategy to Prevent Plastic Pollution

Although plastics have led to many positive innovations that have benefitted human society (e.g. less expensive medical devices, more portable electronic devices, increased fuel efficiency of vehicles made with plastic incorporated in their bodies, etc.), it is clear that plastic pollution is an ever-growing problem that threatens human and environmental health. When considering the fate of all plastic ever produced, Geyer et al. estimated that as of 2015, “approximately 6300 Mt of plastic waste had been generated, around 9% of which had been recycled, 12% was incinerated, and 79% was accumulated in landfills or the natural environment. If current production and waste management trends continue, roughly 12,000 Mt of plastic waste will be in landfills or in the natural environment by 2050.” [Note: Mt=million metric tons] In its 2022 report, Global Plastics Outlook: Economic Drivers, Environmental Impacts and Policy Options, the Organisation for Economic Co-operation and Development (OECD) stated that “Widespread plastics use and inadequate prevention measures have led to persistent plastic leakage. In 2019 an estimated 22 Mt of plastics leaked into the environment. The largest leakage source (82%) is mismanaged waste, i.e. waste that is inadequately disposed of. Other sources are abrasion and losses of microplastics (12%), littering (5%) and marine activities (1%).” They define “mismanaged waste” as “Waste that is not captured by any state-of-the-art waste collection or treatment facilities. It includes waste that is burned in open pits, dumped into seas or open waters, or disposed of in unsanitary landfills and dumpsites.” Even when plastics are collected and processed at a recycling facility, there is still potential for pollution. A study published this month in the Journal of Hazardous Materials Advances describes the analysis of wastewater from a UK plastics recycling facility before and after filters were installed. While filters decreased the discharge of microplastics, even with the filters in place, the total discharge from the multiple washes used in processing could produce up to 75 billion particles per cubic meter of wastewater. If these findings are extrapolated across the whole of the plastics recycling industry, the potential pollution from plastic recycling facilities alone is mind-boggling.

Plastics in the environment break down into smaller and smaller pieces over time. The full extent of the impacts of micro- and nano-plastics on Earth’s ecosystems is unknown, but we do know that wildlife may ingest plastic accidentally when eating food waste contained in plastic, because of visual similarities of plastics to their food sources, and in some cases because the plastic smells like food. When prey animals consume plastic, their predators ingest the plastic along with the prey. Even humans can ingest plastic in this way, and microplastics can also be inhaled. Microplastics are found worldwide, even in protected areas. They have been found in sea ice in the Arctic and on the ocean floor. They’ve even been found in human breast milk.

Given the scale and ubiquity of plastic pollution, in April 2023 the U.S. Environmental Protection Agency (EPA) released a Draft National Strategy to Prevent Plastic Pollution This builds upon EPA’s National Recycling Strategy, focusing on means to reduce, reuse, collect, and capture plastic waste.

image of national strategy cover pageEPA has identified three key objectives for the strategy. The draft strategy document lists proposed actions associated with each objective.

  • Objective A: Reduce pollution during plastic production. This entails designing products for reuse and recycling, using less impactful materials, phasing out unnecessary products, and ensuring proper controls at plastic production facilities.
  • Objective B: Improve post-use materials management. This involves the pursuit of circularity through pathways susch as reuse, refilling, and composting.
  • Objective C: Prevent trash and micro/nanoplastics from entering waterways and remove escaped trash from the environment. The pursuit of this objective may involve policy, programs, technical assistance, compliance assurance efforts, improved water management, improved measurement, increased public awareness, and further research.

Read the full draft strategy at https://www.epa.gov/system/files/documents/2023-04/Draft_National_Strategy_to_Prevent_Plastic_Pollution.pdf. An executive summary is also available.

EPA has opened a public comment period on this draft national strategy. Comments are due on or before June 16, 2023. EPA is asking the public to consider several key questions when reviewing and commenting on the draft strategy. To see these questions and learn more about how to submit your comments, see https://www.epa.gov/circulareconomy/draft-national-strategy-prevent-plastic-pollution#feedback.

#BeatPlasticPollution on World Environment Day

Today is an important “holiday” of sorts for those of us who are sustainability professionals. On this day in 1972, the United Nations Conference on the Human Environment, held in Stockholm Sweden, began (June 5-16, 1972). The purpose of that conference was to discuss human interactions with the environment, as well as encouraging governments and international organizations to take action related to environmental issues and providing guidelines for such action. This was the UN’s first major conference on international environmental issues, and it culminated in what’s commonly called the “Stockholm Declaration”—the first document in international environmental law to recognize the right to a healthy environment. Two years later, in 1974, the first World Environment Day was held on June 5 with the theme of “Only One Earth.” Since then, World Environment Day has been celebrated annually on June 5th. Each year has a theme around which activities center, and beginning in the late 1980s, the main celebrations began to rotate to different cities around the globe. Learn more about the UN Conference on the Human Environment at https://sustainabledevelopment.un.org/milestones/humanenvironment and the history of World Environment Day at http://worldenvironmentday.global/en/about/world-environment-day-driving-five-decades-environmental-action.

This year’s World Environment Day theme, chosen by the host nation, India, (New Delhi is the host city) is “beating plastic pollution,” with the tagline “If you can’t reuse it, refuse it.” According to the World Environment Day web site: “While plastic has many valuable uses, we have become over reliant on single-use or disposable plastic – with severe environmental consequences. Around the world, 1 million plastic drinking bottles are purchased every minute. Every year we use up to 5 trillion disposable plastic bags. In total, 50 per cent of the plastic we use is single use. Nearly one third of the plastic packaging we use escapes collection systems, which means that it ends up clogging our city streets and polluting our natural environment. Every year, up to 13 million tons of plastic leak into our oceans, where it smothers coral reefs and threatens vulnerable marine wildlife. The plastic that ends up in the oceans can circle the Earth four times in a single year, and it can persist for up to 1,000 years before it fully disintegrates. Plastic also makes its way into our water supply – and thus into our bodies. What harm does that cause? Scientists still aren’t sure, but plastics contain a number of chemicals, many of which are toxic or disrupt hormones. Plastics can also serve as a magnet for other pollutants, including dioxins, metals and pesticides.”

To combat the environmental and human health issues associated with the global addiction to single use plastics, the UN Environment Programme is encouraging people to join the global game of #BeatPlasticPollution tag. Here’s how to play:

  1. Choose which type of single-use plastic you’re ready to give up.
  2. Take a selfie (photo or video) showing yourself with the reusable alternative that you’re ready to embrace.
  3. Share your selfie on social media and “tag” three friends, businesses or high-profile people to challenge them to do the same within 24 hours. Be sure to use the #BeatPlasticPollution hashtag and mention @UNEnvironment.

So what single use plastic item will you pledge to give up today—plastic straws, disposable plastic shopping bags, disposable coffee pods, plastic water bottles, or something else? For inspiration, see http://worldenvironmentday.global/en/get-involved/join-global-game-beatplasticpollution-tag.
