ISTC Technical Assistance Program assists U. of I. campus with waste characterization study

ISTC and F&S staff sorting waste samples.

The University of Illinois Urbana-Champaign (U. of I.) Facilities & Services (F&S) Waste Management department recently released the results of a campus building waste characterization and opportunity assessment conducted with assistance from the ISTC Technical Assistance Program (TAP). This project was the latest example of collaboration between the two units on reducing waste and improving sustainable materials management on campus since the development of the original Illinois Climate Action Plan (iCAP).

Beginning in 2014, shortly after the inception of its Zero Waste Illinois program, TAP conducted its first university campus waste audit in the form of a two-phase project for U. of I., examining the types and amounts of waste generated in eight campus buildings, as well as the availability and location of waste and recycling collection bins. That study also included a survey of building occupants to gauge knowledge of current programs, gaps in service, and overall satisfaction with the campus recycling program. With this data, TAP made recommendations for waste reduction and diversion at the campus and individual building levels. The TAP zero waste team went on to conduct similar waste characterization studies for other institutes of higher learning, industrial clients, local governments, small businesses, and school districts in Illinois and beyond, as well as contributing to statewide systemic change through efforts like the Farm to Food Bank feasibility study and pilot projects. In 2019, TAP assessed indoor solid waste and recycling collection infrastructure for U. of I., leading to the initial deployment of branded three-bin collection stations for waste and recyclables in high-traffic campus locations. F&S continues to deploy those newer three-bin stations as funding permits, as part of ongoing progress toward iCAP zero waste goals.

In the fall of 2021, TAP, F&S, and other campus stakeholders began discussion of a new round of campus building waste audits. Plans were paused until after the hiring of Daphne Hulse, the first full-time U. of I. Zero Waste Coordinator, in fall 2022, to ensure the availability of dedicated staff to address waste audit results and recommendations. A spring 2023 grant from the U. of I. Student Sustainability Committee (SSC) supplemented available F&S funds to secure TAP services for waste audits of eight high-usage facilities in October 2023.  

Due to the size and volume of waste and recycling generated on campus, sorting all material was not feasible. Thus, TAP and F&S used an “activity zone” approach, developed by the TAP zero waste team after their work on the previous U. of I. campus audits. This involved selecting a representative set of buildings classified according to their main functions and services. Waste audit data from those representative buildings was used to formulate recommendations for waste reduction and improving the quantity and quality of collected recyclables. Those recommendations for improvement can then be applied to other buildings that fall within the same activity zone categorization. For this waste audit, activity zones and their respective buildings included:  

  • Academic: Business Instructional Facility (BIF) & Campus Instructional Facility (CIF)
  • Academic + Laboratory: Roger Adams Laboratory (RAL) & Noyes Laboratory
  • Multi-Activity: Illini Union & Activities & Recreation Center (ARC)
  • Student Living: Lincoln Avenue Residence Halls & Allen Residence Hall

TAP conducted walkthroughs of study buildings to assess current conditions and infrastructure, discuss waste and recycling challenges and successes with facility managers and other key personnel, and determine the best method for sample collection during the waste audits. The audits involved the collection of samples from trash (landfill-bound) and recycling streams from each of the selected buildings, which were then hand-sorted by TAP staff and volunteers into pre-determined categories defined in conjunction with F&S waste management staff. Following the waste audits, TAP held four focus group sessions (one per activity zone) to obtain input from campus community members (including students, faculty, and staff). Stakeholder engagement helped to gauge expectations, barriers, and sources of confusion, as well as garner suggestions for ways to reduce waste and improve collection of recyclables for the buildings included in the study. An online form was made available for submission of written feedback from those unable to attend focus group sessions and to allow session participants to submit any additional comments and suggestions. 

In addition to presenting methodologies and findings, the audit report outlines current waste and recycling management practices across campus and within the examined activity zones. This includes detailed descriptions of bin liner color-coding standards and the rationale behind them, procedures at the campus Waste Transfer Station (WTS), process flow diagrams, and a list of processors and destinations for the major categories of collected recyclables. The goal was to create a document that could support F&S’s efforts to educate and engage the campus community in improved waste management and the creation of a zero-waste culture. 

There are long-standing misconceptions about campus waste management practices according to Joy Scrogum, an Assistant Research Scientist with ISTC’s TAP and a member of the campus Zero Waste iCAP team. “When I was an Illinois undergraduate, I would hear people say it didn’t matter if you accidentally put recyclables in campus trash bins because everything would be sorted at the campus Waste Transfer Station. That was frankly decades ago, and I still hear people make that incorrect assertion. Although the U. of I. is an innovative research institution, our Waste Transfer Station is low-tech, with a small crew that hand sorts only a fraction of the materials collected. There’s no cutting-edge equipment using lasers or air currents to extract recyclables, just humans pulling items from certain colored bags that are emptied onto a conveyor belt. It would be physically impossible to hand sort all the waste generated on campus, and most people aren’t even aware of the fact that different colored bin liners are meant to signify different actions at the transfer station. The contents of black bags, for example, aren’t emptied for a hand sort, because that color is supposed to signify waste collected from restrooms or laboratories.”

The study uncovered a lack of awareness, confusion, and/or inconsistent compliance regarding the bin liner color-coding standard, suggesting that improved communication and efforts to ease supply chain barriers could result in increased capture of recyclable materials. Observations during building walkthroughs and feedback compiled from stakeholder engagement indicated that greater consistency in collection bin style and signage, along with improvements in communication of proper waste management and recycling procedures to students, faculty, and staff could result in improved collection and reduced contamination of recyclable materials. 

Key findings from the analysis include: 

  • 34 percent of campus waste reviewed was avoidable 
  • 23 percent of all landfill materials were some form of paper towels
  • Recyclable materials made up 13 percent of the total waste stream
  • 17 percent of waste was compostable
  • 18 percent of recyclables were contaminated and therefore unsalvageable
  • Liquids contributed to contaminating 5 percent of all the recycling items sorted
Disposable single-use items, such as these beverage cups, are examples of potentially avoidable waste.

TAP made 39 recommendations for waste reduction and improved management grouped into seven themes (education & outreach, infrastructure, policy, programming, purchasing, research, and retail). Many of the suggestions encourage colleges and departments to look upstream at the source of waste generation to proactively reduce the amount of waste that ends up in landfills.

F&S Zero Waste Coordinator Daphne Hulse said, “ISTC’s important and updated insight gives us the ability to turn their work into meaningful results that have an impact across campus. To accomplish our goals, we need to keep looking at how we can all continue to make progress by taking all available actions to properly reduce, reuse, and recycle where we study, work, recreate, and live.” 

A more detailed summary of study findings, along with the full report and executive summary for download, are available on the F&S website at https://fs.illinois.edu/campus-building-waste-characterization-opportunity-assessment/.

Daphne Hulse will also discuss the audit results, the details of campus waste and recycling management, and ongoing zero waste initiatives in an ISTC Sustainability Seminar presentation entitled, “Landfills Are Organized Littering: How the University of Illinois Is Moving Toward Zero Waste.” This hybrid presentation (with in-person and online attendance options), is scheduled for September 11 from 2-3 PM.

ISTC Sustainability Seminars are recorded with archives available online within a few weeks of the seminar’s completion. 

August 1, 2024, marks “Earth Overshoot Day”

Earth Overshoot Day Logog

Since 1971, the Global Footprint Network has calculated “Earth Overshoot Day” to highlight the impacts and implications of human resource consumption. As stated on the event website, “Earth Overshoot Day marks the date when humanity’s demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year. We maintain this deficit by liquidating stocks of ecological resources and accumulating waste, primarily carbon dioxide in the atmosphere.”

“To determine the date of Earth Overshoot Day for each year, Global Footprint Network calculates the number of days of that year that Earth’s biocapacity suffices to provide for humanity’s Ecological Footprint. The remainder of the year corresponds to global overshoot. Earth Overshoot Day is computed by dividing the planet’s biocapacity (the amount of ecological resources Earth is able to generate that year), by humanity’s Ecological Footprint (humanity’s demand for that year), and multiplying by the number of days in a year. This year, as we are in a leap year, it is 366 days:

(Earth’s Biocapacity / Humanity’s Ecological Footprint) x 366 = Earth Overshoot Day”

In 2024, Earth Overshoot Day falls on August 1st.  Collectively, humanity would need 1.75 Earths to meet its resource demands.

The numbers get worse if you look at consumption at the country level. If everyone globally lived like the residents of the United States of America, Earth Overshoot Day would have occurred on March 14th this year, and humanity would need the equivalent of five Earths to match resource demands.

See https://overshoot.footprintnetwork.org/2024-calculation/ to learn more about how this year’s Earth Overshoot Day was calculated.

Clearly, none of this is sustainable. So what can we do to #MoveTheDate later in the year, so our demands better match the ability of Earth to regenerate ecological resources? The Global Footprint Network presents potential solutions to pursue individually and collectively as “The Power of Possibility” in five main categories:

  • Cities: How we design and manage cities
  • Energy: How we power ourselves
  • Food: How we feed ourselves
  • Population: How many of us are there
  • Planet: How we help nature thrive

See https://overshoot.footprintnetwork.org/power-of-possibility/ to learn more about potential strategies in each of these categories in detail. For each strategy, the Earth Overshoot Day website explains how much implementation would shift the overshoot date and how the strategy is scalable. The website also provides classroom activities and a link to a personal environmental footprint calculator to help individuals understand their lifestyle impacts.

Dr. Mathis Wackernagel, who created the concept of the environmental footprint with Professor William E. Rees in the early 1990s, provides an online primer to understanding the implications of overshoot and how to respond. He states “Because the accumulated stock of nature is finite, overshoot will inevitably end as stock get depleted. The question, therefore, is not whether it will end, only how. It can end by design or by disaster – most likely it will be a combination of both.” Let’s work together to do our best to end overshoot by design.

Back-to-School tips for more sustainable supplies

office supplies

It hardly seems possible, but August is just around the corner, and for many K-12 schools and institutions of higher education in Illinois, that means it’s back-to-school season. Whether you’re a parent with a school supply list in hand, a college student preparing for a new semester, or just someone in the market for office supplies, the following suggestions can help you make more sustainable choices as a consumer.

Please note that ISTC does not endorse, either explicitly or implicitly, any manufacturer, brand, vendor, product, or service. Information about specific products, brands, manufacturers, or vendors is provided for reference only and should not be construed as an endorsement. Also, please be aware that this list of suggestions and alternatives to consider is by no means exhaustive and is meant simply to inspire you to be more intentional in your consumption and to consider the impacts of everyday items.

First, shop your own supplies & reuse/use up what you already have.

Parents of elementary-aged children will likely relate to the experience of kids cleaning out their lockers or desks at the end of a school year and bringing home partially used notebooks, used folders, pens, pencils, etc. While it’s possible that some items from the previous academic year are nearly worn out, or that these items might be used up over the summer for non-school activities, it’s also likely that at least some tools and supplies will still have useful life left when it’s time to begin a new school year. Designate a closet, shelf, or storage bin in your home or office to store school or office supplies that aren’t currently in use, so that when you need such supplies, you can quickly check your existing inventory and draw from it before you go shopping. Establishing this habit will save both money and the resources used to manufacture the supplies in question.

Shop for gently or never used supplies at a creative reuse center.

If the items you need aren’t part of your existing inventory, check to see if there is a creative reuse center in or near your community. These centers accept donations of supplies for art and education, as well as non-traditional materials that might be used for arts, crafts, school projects, lessons, and home décor, which would otherwise be sent to the landfill. These “non-traditional materials” might be hard-to-recycle items, or simply objects of visual or textural interest that might be transformed in a creative way. Examples of creative reuse include painting an old tin and using it as a planter, turning fabric scraps into a quilt, or making a collage from colorful buttons, bottle caps, or photos. Donations to creative reuse centers typically come from businesses, manufacturers, local institutions, and members of the general public. Such centers then resell the donated items for profit or to support charitable organizations or initiatives while reducing waste and encouraging reuse. Think of them as thrift stores focused on art and office supplies. Some donated items have never been used. Like checking your own inventory before buying new, shopping at creative reuse centers will not only conserve resources by ensuring products remain in use and out of landfills for as long as possible, but they also typically save consumers money as compared to shopping for brand new items. So, once you’ve checked your own inventory of supplies, check your community’s pool of supplies. Multiple creative reuse centers exist in Illinois. Champaign-Urbana is served by the Idea Store, while the WasteShed operates creative reuse centers in Chicago and Evanston. Chicago is also served by Creative Chicago Reuse Exchange (CCRx). SCARCE serves DuPage County and is in Addison, IL. Springfield residents can shop at the Creative Reuse Marketplace. Keep in mind that other resale shops and thrift stores might also have office supplies, so if your community doesn’t have a creative reuse center, you might still be able to find “new to you” supplies that would otherwise have been wasted. Creative reuse centers can be found throughout the U.S., so if you’re reading this from outside Illinois, do an Internet search for “creative reuse center + [name of your state].”

Choose refurbished devices and remanufactured ink and toner cartridges.

Continuing the theme of reusing existing products before buying new ones, if you’re in the market for a new laptop or other electronic device, consider searching for a certified refurbished device first. While you would be wise to think twice before purchasing “used” items from a complete stranger on a platform like eBay or Craigslist, certified refurbished items have been restored to “like new” condition and verified by technicians to be fully functional. Quality is thus not an issue. But because these items can’t be sold as new, they’re typically available at a discount when compared to genuinely new items. Another win-win for the conservation of resources and money! Many companies such as Best Buy, Dell, or Amazon make it easy for consumers to find refurbished devices in their online stores. The downside of shopping for refurbished tech is that you can’t guarantee you’ll find the exact model or item you’re looking for at the precise time you search; it depends on what is available.

There are also non-profit and for-profit organizations throughout the U.S. which refurbish electronics (typically donated) and resell them at a discounted price to individuals who might otherwise not be able to afford such equipment. These organizations address both social and environmental aspects of sustainability, helping to bridge the digital divide while extending the useful life of products and stemming the ever-growing tide of e-waste. Keeping these entities in mind is great if you or someone you know needs help obtaining a device, or, on the other hand, if you’d like to donate an older device so someone else can benefit from it. You’ll find that reputable businesses in this sector can provide certification of data destruction, so security need not be a concern. Some of these organizations include a job training program, enhancing their positive impacts on communities. Some may also provide electronics recycling services to businesses, responsibly recycling devices that can’t be reused, and refurbishing and redistributing those that can. REcompute began in Champaign-Urbana, IL, and has expanded to Danville, IL, Los Angeles, CA, and is coming soon to Atlanta, GA. PCs for People has ten locations in the U.S., including two in IL (Oak Forest and Belleville). Free Geek began in Portland, OR, and multiple communities in the U.S. and abroad have started their own independent Free Geek organizations. Repowered in St. Paul, MN, is another example.

Remanufactured ink and toner cartridges have been professionally cleaned, refilled, and tested, decreasing demand for the plastics and other materials used to create the cartridges themselves. Life-cycle assessments (LCAs) have even shown that remanufactured cartridges have lower environmental impacts than brand-new cartridges. And again, you’ll save money as well as resources by practicing reuse.

Choose items that are refillable.

If you must buy a brand-new item, look for options that will foster future reuse through refilling. The classic example (and the one most likely to be compatible with K-12 supply lists) is choosing a refillable fountain, gel, or ballpoint pen instead of a disposable one. There are plenty of examples of such pens, but one that also incorporates recycled content is Pilot’s B2P or Bottle 2 Pen. B2P is made from recycled beverage bottles, is available as a ball-point or gel roller, and uses the same ink refill cartridges (available in several colors) that work in several other Pilot pens. For more info, see https://pilotpen.us/FindBrand and select “Bottle 2 Pen B2P” from the drop-down menu. The pens are 86-89% recycled content depending on pen type; product descriptions for the ball points say they are 83% post-consumer recycled material.

Mechanical pencils are a similar refillable option that immediately comes to mind. Bic produces an example of a mechanical pencil with recycled plastic content.

Refillable notebooks give you the compact feel of a spiral-bound notebook, as compared to a bulky three-ring binder, but like binders, allow you to insert new pages as needed or rearrange the order of notes. Some examples include Kokuyo Binder Notebooks, Lihit Lab, Filofax, and Minbok.

Dry erase markers are even available in refillable versions, such as the Pilot V Board Master or those from Auspen. The Stabilo Boss is an example of a refillable highlighter. Permanent markers such as those from Pilot can be refilled. Refillable acrylic markers are also available from brands like Montana. Crayola also has a DIY Marker Maker set, but they unfortunately don’t sell a refill pack. However, these could conceivably be refilled with inks available from other companies.

Choose new items made from recycled materials and look for high PCR content.

If refillable options aren’t available or applicable to some supplies on your list, try to find options made from recycled materials. When comparing options, examine product labels and descriptions for the percentage of “post-consumer recycled” content or “PCR.” These are materials that have been used by consumers and collected via recycling programs, so when you buy a product with the highest amount of PCR you can, you are genuinely “closing the loop” and making recycling effective and economically feasible by helping to create market demand for recycled materials. You’ve probably read articles about materials collected for recycling that ultimately don’t get recycled because there’s a lack of market for the commodities. That sort of thing has led some community recycling collection programs to stop altogether or to stop accepting certain materials. But most of the time, if a recycling collection program accepts a material it’s because they have an outlet for it; it wouldn’t make sense to collect materials that couldn’t be sold. The best things you can do as a consumer is to keep recycling the proper materials accepted by your local program, keep items NOT accepted by your collection program out of your recycling bins (contaminants can indeed ruin batches of materials collected or harm equipment at waste sorting and processing facilities), AND whenever possible, buy items with PCR content. Note that if a product is described as having a certain percentage of recycled content but there’s no mention of PCR, it’s likely that the recycled content is post-industrial (aka pre-consumer) rather than post-consumer. That entails excess materials or trimmings from a manufacturing process used as feedstock for the creation of the same or different products without ever being used by a consumer first (e.g., cardboard trimmings repulped and put back into the process of making boxes). Odds are, if a company has successfully incorporated PCR into their products, they will want to point it out on the label or in the product description/details in online stores. This blog post from EcoEnclose provides a good overview of PCR vs. post-industrial content.

That said, here are just a few examples of common supplies made from PCR (besides those already mentioned above). You can find more by searching the Internet for “PCR content + [product].”

  • Standard (non-mechanical) pencils can be made from recycled newspaper, like these from Amber and Rose.
  • Decomposition notebooks, sketchbooks, and filler paper are made from 100% PCR paper. They also offer refillable ball-point pens made from 90% PCR plastic and three-ring binders made from 85% PCR plastic.
  • Everyday Recycler provides this list of backpacks containing recycled plastic.
  • 100% PCR printer paper is available, such as that from Printworks, AbilityOne, or Target.
  • ACCO paper clips contain 90% recycled materials, 50% of which is PCR.

Hopefully, this has given you some ideas for considerations and criteria to keep in mind when looking for school and office supplies. There are certainly other product categories and other factors that can be considered (e.g. more renewable materials, plastic-free items, items manufactured with renewable energy, etc.), but the suggestions above are a great start. Students, good luck in your classes, and may everyone else be productive while also conserving resources!

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.

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.

“Green” your Halloween with these seasonal waste diversion programs

What do the members of the ISTC Technical Assistance Program’s zero waste team fear the most? Unnecessary waste! Think about all the products and packaging sent off to be prematurely buried in landfills before their useful “lives” are truly over–it makes our blood run cold. To avoid being haunted by the ghosts of poorly managed materials, check out the following Halloween waste diversion programs to keep waste out of landfills.

Please note that links and/or mentions of organizations or businesses are provided for informational purposes only and should not be construed as endorsements by the Technical Assistance Program, ISTC, the Prairie Research Institute, or the University of Illinois.

Pumpkin Smash Events

Did you know that IL leads the nation in production of pumpkins? Did you further know that pumpkins are mostly water? A great deal of labor, land, water, and other resources are invested in growing, harvesting, and distributing pumpkins in our state, and many of them end up being used for brief decorations that may wind up in landfills after Halloween has passed.

Pumpkin “Smash” events are events to collect jack-o-lanterns and other pumpkins for composting. They’re held on the Saturday after Halloween (November 5th this year), and may involve fun activities in which people can “smash” their pumpkins by throwing them into a designated dumpster or compost heap. Some events even involve pumpkin “chucking” with catapults! SCARCE has helped Pumpkin Smashes grow to over 59 sites across IL since 2014, and their efforts have even inspired communities outside of IL to host their own pumpkin collections. According to the SCARCE website, the 2021 Pumpkin Smash events collectively composted over 242 tons of pumpkins! See https://www.scarce.org/pumpkins/ for more information, including a map of registered events in the state, a guide for hosting a Pumpkin Smash to help with planning for next year, a form to register your local event so it will be included on the aforementioned map, and example flyers and other resources to help spread the word. See this recent Illinois Food Scrap Coalition blog post and flyer developed by Go Green Winnetka for further information.

Candy Wrapper Recycling Programs

When you’re hosting a Halloween party or having kids trick-or-treat at the homes of people you know and trust, there are opportunities to pass out/receive homemade or minimally-packaged bulk treats and reduce the amount of plastic packaging associated with Halloween festivities. However, the reality is that many people pass out candy to or collect candy from strangers; plus, many of us like to purchase Halloween candy to share with coworkers or our family during the month of October as part of celebrating. The result is lots of plastic packaging ending up in landfills because such material is not collected in typical recycling programs because the form or components of the packaging make them difficult to recycle. There are however, a couple of options that can help divert the seasonal increase in candy wrappers from the landfill.

Trick or trash box
Trick or Trash collection box available from Rubicon.

Rubicon, in collaboration with the National Wildlife Foundation, annually offers a Trick or Trash program, in which schools, independent small businesses, and community organizations can order FREE candy wrapper collection boxes. Organizations receive their collection boxes through the UPS Carbon Neutral Shipment program, set them up and collect wrappers until their box is full. Then, boxes are sealed and mailed back using a pre-affixed label. Each participating organization gets a certificate of recycling confirming how many wrappers they diverted from landfill. The recycled plastic can be used to make “doggie bags” used at animal shelters for animal waste collection. See https://www.rubicon.com/trick-or-trash/how-it-works/ for more information, and https://www.rubicon.com/trick-or-trash/#block_5aee8cc625f6cfa2532fd2b387a4e675 to order a free box. Educational materials, including lesson plans, are available at https://www.rubicon.com/trick-or-trash/education/. Note that teachers and organizations are limited to one free box to ensure that more people across the country can participate, and you should allow at least a week for shipping. So if you order a free box now, you might plan to collect wrappers right after Halloween, rather than at Halloween events. Individuals or larger business might choose to purchase a box for participation.

TerraCycle also sells “zero waste boxes” for various hard-to-recycle waste streams, including candy and snack wrapper zero waste boxes. That company also collaborates with various Subaru locations nationwide that host collection boxes for items including disposable cups, lids, straws, candy and snack wrappers, and coffee and creamer capsules. Learn more on the TerraCycle Subaru Loves the Earth web page and search for a participating location near you.
