In a previous post, we noted that September 16-20, 2024 is Pollution Prevention (P2) Week, and highlighted some relevant projects of the ISTC Technical Assistance Program (TAP). To conclude the week, we’ve compiled some video resources that may be of interest, whether you’re unfamiliar with “pollution prevention” or a seasoned practitioner.
“Pollution prevention,” also known as “source reduction,” is any action that reduces, eliminates, or prevents pollution at its source before recycling, treatment, or disposal. While the term may at first evoke images of smokestacks spewing dirty clouds into the sky or pipes discharging visibly dirty liquids into waterways, P2 is not just for industrial facilities. We all use natural resources, and we all encounter materials at work, regardless of the sector we work within, or in our schools or homes that may cause harm to human or environmental health. So we all have opportunities to use raw materials, water, energy, and other resources more efficiently, or to substitute less harmful substances for hazardous ones. The old proverb, “An ounce of prevention is worth a pound of cure” rings true in terms of protecting human and environmental health, as well as strengthening our economic well-being.
Pollution Prevention Playlist (8 videos) from the Arizona Department of Environmental Quality (ADEQ). This includes an explanation of the circular economy; tips for individuals such as donating goods, using reclaimed building materials, composting, and xeriscaping; and housekeeping tips for auto shops.
Pollution Prevention (P2) Mini-Webinar Series(5 brief videos per year). Each year the Minnesota Technical Assistance Program (MnTAP) produces a short video for each day of P2 Week. For 2024, videos include “Waste Hierarchies” presenting different strategies for managing waste, “Coffee Machines,” focused on an easy way to save energy, “Conductivity Probes,” focused on saving water in industrial settings, “Anesthetic Gases” on a surprising source of greenhouse gas emissions in healthcare settings, and “About MnTAP” introducing the organization and its services. Be sure to check out archives from past years, going back to 2021.
If you’d like to learn more about perfluoroalkyl and polyfluoroalkyl substances (PFAS):
Reducing PFAS in Products: Progress and Challenges (1 hr., 2 min., 33 sec.). This recorded webinar examined U.S. EPA’s PFAS Strategic Roadmap and a new online tool for EPA’s Recommendations of Specifications, Standards, and Ecolabels for Federal Purchasing that highlights how standards and ecolabels address PFAS. Speakers from EPA, EPA grantees, and a nonprofit organization discussed the progress they have made to increase the availability and use of products without PFAS, and the challenges that remain.
To learn more about choosing safer products in a variety of settings including your home, check out the U.S. EPA Safer Choice Videos collection, also available in Spanish.
Instructors interested in integrating P2 into curricula should explore videos from last year’s “P2 Works” student storytelling challenge. High school and college students used the Toxic Release Inventory (TRI) P2 Search Tool to identify facilities reporting source reduction practices. The students created videos telling a compelling story about how these case studies benefitted relevant businesses, communities, and the environment. Visit this website for descriptions and links to the winning videos.
A webinar recorded earlier this week by the Pollution Prevention Resource Center (PPRC) entitled “Pollution Prevention in EJ Communities” (1 hr., 8 min., 28 sec.) summarizes the results of a recent two-year project funded by the U.S. EPA, including adjustments made throughout the project for better reach, engagement, and service to participating businesses.
Finally, the ISTC Sustainability Seminar Series frequently features P2 topics. Visit the series webpage to learn more and explore archived recordings going back to 2007.
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
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.”
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.

US EPA is hosting virtual feedback sessions to solicit input on new Bipartisan Infrastructure Law initiatives on end-of-life battery collection and labeling. A recent session was held on 6/15/22; in case you missed that, register for a similar session June 30, 2022 from 11:30 AM to 12:30 PM Central Time at https://www.zoomgov.com/webinar/register/WN_izu6yTpXTYG2Pjr6mystag. If you require accommodations, please send an email to: meetings@erg.com.
This session will cover two EPA initiatives under development:
Battery collection best practices that are feasible for tribal, state, and local governments, environmentally sound for waste management workers, and increase the recovery of critical minerals.
Battery labeling guidelines to improve battery collection including by:
identifying collection locations,
promoting consumer education about battery collection and recycling, and
reducing the improper disposal of batteries and associated fires.
EPA is seeking feedback on:
What types of batteries should EPA include in the best practices for collection (e.g., small consumer batteries, electric vehicle and grid storage batteries, industrial batteries, etc.)?
What are the current barriers to safe and effective battery collection and recycling?
What practices exist to improve battery collection and recycling, especially to increase the safe recovery of critical minerals?
What types of communication and outreach activities are most useful to reach key battery stakeholders?
What existing labeling programs should EPA use to inform a new labeling program?
Who should attend?
The session is open to all stakeholders involved in the battery lifecycle, including:
battery manufacturers,
battery retailers,
battery recyclers,
consumers and businesses that purchase batteries,
companies in the electric vehicle management chain, and

Members of the ISTC Technical Assistance Program team recently presented a webinar in association with Sustain Rockford to describe an opportunity for Illinois manufacturers, their direct suppliers, and supporting industries to obtain free sustainability assessments. The webinar recording is now available on ISTC’s YouTube channel.
TAP has received federal grant funding to provide these assessments for the following sectors:
Assessments can help facilities reduce business costs, energy and water consumption, wastewater generation, emissions, and hazardous material usage, which can result in increased profitability, productivity, and competitiveness as well as recycling or diversion of by-products.
The recorded presentation describes: how interested facilities can sign up for the opportunity; the process of preparing for an assessment; what to expect from the report on findings provided by TAP (including some example elements and common opportunities identified); and how TAP can assist with implementation of recommendations, if desired.
According to GRF, more than 28 million glass bottles and jars end up in landfills each year, despite the fact that glass is endlessly recyclable. Recycling glass can protect the environment, economy, and sustainable manufacturing by capturing materials for reuse and keeping them out of landfills, as well as preventing litter from polluting the ocean and beaches.
To improve glass diversion from landfills and educate the public about the importance of glass recycling, Constellation Brands and its popular beer brand, Corona, have teamed up with GRF for a glass recycling initiative as part of the Corona Protect Our Beaches campaign.
This pilot program involves glass bottle recycling at Chicago-based bars and restaurants. Participating locations will separate their glass bottles into a separate bulk bin for pick up, starting in late June 2021. The GRF pays a hauler for the pick-ups; there is no cost to the participating locations. Any glass bottle, not just Corona-branded bottles, can be recycled, and no color sorting of bottles is required (as noted during the webinar Q&A). Additionally, a small amount of incidental contamination (e.g. napkins or straws) is acceptable. This creates a simple system for the participating pilot locations.
The glass recycling pilot will be paired with special events including an interactive experience that sheds light on the need for glass recycling and helps “crush the problem.” At these events, empty bottles will be turned into a sand-like powder using a grinding machine that allows members of the public to watch the process, thus capturing their attention and imagination. Event attendees learn about the program and the call to action, “#DontTrashGlass.” Select consumers will be able to feed empty bottles into the grinding machine. Events will also feature a sand art station for attendees to enjoy as they learn about the benefits of recycling glass. According to Defife and Lang, the grinding machine is actually relatively quiet; the generators used to power the machine at these events is louder than the machine itself. The sand-like substance fits well with the theme of Corona’s Protect Our Beaches campaign and brand identity. GRF recognizes that there are many ways to use recycled glass and beach restoration is one of them; in addition, bottles can become new bottles, fiberglass, construction aggregate, sandblasting, and more.
Over the course of nine weeks this summer, the grinding machine will tour ten different wholesalers and corresponding accounts. The complete list of grinding events is available at https://protectbeaches.com/events/. Events kick off on June 25 at two locations in St. Charles, IL, and one in West Chicago.
During the webinar, it was noted that additional restaurants and bars can be added to the pilot in the Chicagoland area by contacting Defife or Lang (their email addresses are provided at the end of the webinar recording). Also, the collaborative team is trying to figure out what it would cost to continue the recycling program beyond the pilot period. A similar pilot is taking place in Phoenix, AZ, in partnership with Glass King. At the end of the pilot the total tonnage of glass recycled will be measured to illustrate diversion impacts. Participating locations will also learn valuable information about the nature of their waste streams from those measurements.
