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.

VIDEO 10: Mark Ryan After leading the assembly in “Happy Birthday” to ISTC, Ryan shared a brief survey of the history of “sustainability in the modern context.” In 1980, sustainable development was called a global priority in “World Conservation Strategy” published by the International Union for of Conservation of Nature.

 

The United Nation’s Bruntland Commission defined it in 1987: “Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

 

But sustainability in the sense of natural resources goes back thousands of years to so many cultures across the globe that Ryan said he was comfortable labeling it a “universal truth.”

 

For examples in ancient times he cited, “Deuteronomy’s” caution not to kill female birds with young, forest management practiced in the Han Dynasty, and the Roman latifundium which managed the production of wood and other crops. Ryan noted that when Rome fell, and latifundia disappeared, so did many of the forests in Italy and France.

 

Ryan continued to offer examples of preserving resources for future use through the centuries, right up to the establishment of the Illinois Sustainable Technology Center in 1985.

VIDEO 9: State Senator Scott Bennett’s presentation gave insights on how policies work their way through the state legislature. For 10 years politics, policy and science questions surrounded a proposal to store PCBs and manufactured gas plant waste in a DeWitt County landfill positioned over the Mohamet Aquifer.

 

He has been active in promoting legislation to protect the aquifer, which is a critical source of drinking water for a large region of central Illinois. Another pending bill to protect the state’s natural infrastructure is a comprehensive program to monitor the quality of air, water, and land resources. Also, a proposed law would allow cities to collect fees from power plants to prepare for the costs of environmental cleanup when the plant eventually closes down.

VIDEO 8: Jerri-Anne Garl represented the federal Environmental Protection Agency during the ISTC Anniversary Celebration. Since EPA’s pollution prevention program started in the early 1990s, ISTC “has been one of our most effective and innovative partners,” Garl said. “ISTC itself has served as a model for other state programs.” She outlined successes of ISTC programs in assisting local communities and small companies, as well as major manufacturers, save money, water, energy, and make their operations more environmentally friendly.

 

Garl reviewed federal priorities for the EPA: 1) making a visible difference in communities; addressing climate change and improving air quality; launching a new era of state, tribal and local partnerships; and embracing EPA as a high performing organization. She added that the agency has set three emphasis areas for its work: climate change, food manufacturing, and hazardous materials mitigation.

 

“We believe that the ISTC is really well-positioned with the tools, experience, connections and the innovative spirit, to be a central partner in this effort.

VIDEO 7: Kevin Greene’s career in the environmental arena spans almost 30 years, including nearly 20 years at the Illinois Environmental Protection Agency. During the early days of the pollution prevention movement, he viewed the reaction against environmental contamination from several perspectives — as an environmental issues consultant, lobbyist, and regulator.

 

He noted that during the 1970s there was a wave of federal environmental laws which represented a change in the environmental community from public activists for change working from outside institutions to working inside them. Early regulations were also aimed at dealing with managing pollution after it was created.

 

A second wave of community activism developed in the 1980s over concern about how effectively industrial by-products were being handled, and their potential health impacts, he said. “Specialists or technocrats” continued to be “at the table” in seeking waste management solutions, but public activists were growing less trusting, he recalled.

 

Activists’ focus shifted away from calls for regulations that manage pollutants to local level activism to halt proposed storage/disposal facilities.  Increasingly the questions became “why is waste being generated in the first place” and the response shifted to getting critical information about pending waste projects to affected communities.

VIDEO 6: Timothy Lindsey As long-time head of technical assistance at the Center, Timothy Lindsey, helped pioneer more effective technical assistance efforts by applying the principals of innovation diffusion. He recalled he and his colleagues at the Center were frustrated when they made recommendations that would clearly save money and trim waste, yet often they were not adopted.

 

As part of his doctoral studies, Lindsey began to apply the ideas of Everett M. Rogers in his book “Diffusion of Innovation.” Innovations are initially perceived as uncertain and even risky, Lindsey said. They must be demonstrated in the context of the scale and type of the existing process. Innovations are most likely to be shared among trusted peers and the process can be slow.

 

Lindsey explained that sustainability in an innovative way of doing business, similar to innovations like the assembly line or electronic commerce. Following innovations in sustainable business, he said,  financial performance, environmental performance and social performance must be considered over the long term.

 

Now Global Director of Sustainable Development at Caterpillar Inc., Lindsey has applied principles of innovation diffusion to the multi-national manufacturer. Sustainability has long been important at Caterpillar, he said. But 2104 was a formative year at the company when sustainability became more than just an important thing they do. “Sustainability became an important part of who we are,” as one of the corporation’s core value, he said.

VIDEO 5: Jeff Levengood, spoke about the strong collaboration between ISTC and the other four state surveys during its history. The diverse expertise of the scientists at the Prairie Research Institute’s four other surveys — spanning water, geology, natural history, and archaeology — enabled them to examining complex, place-based, legacy environmental contamination and degradation issues.

 

The work resulted in research reports published by the center, but also in refereed journal articles. He said this work helped communities around Illinois in managing their contamination problems but the collaborations also made significant contributions to the knowledge base in the field.

 

At Lake Calumet, Waukegan Harbor, Lake DePue and other post-industrial natural habitats, the surveys studied exposure and uptake of pollution by wildlife. They tracked changes in habits including nesting, foraging, reproduction in the birds, fish and the greater ecosystem. The information helped lead to innovative restoration projects at compromised sites in the state.

 

“I think we have to be proud,” Levengood said, “anybody that was involved in those early studies, because we really kind of kicked this off and helped to show what could be, what was possible.”

 

He quoted Nicole Kamins Barker, who worked on the Lake Calumet restoration as part of the Chicago Department of Environment, who said “The Surveys’ involvement took our work in the Calumet region to a new level of effectiveness by merging the latest scientific research with natural resource planning and management.”

VIDEO 4: Craig Colten While working at the Center, Craig Colten, conducted pioneering longitudinal analyses of manufacturing techniques in urban manufacturing sites throughout the state.  The work accounted for changing hazardous materials produced and changing waste handling practices over more than 100 years.

 

The research was valuable for understanding not just current threats but residues from long forgotten industrial sites. Building on this data, Colten was able to construct a general historical geographic model in urban areas, as well as a series of tools and applications including a Historical Hazardous Substance Data Base and a Historical Hazards Geographic Information System. These tools helped establish the ground work for Superfund litigation and the ability to support real estate transactions.

 

Colten and others at the Center became national leaders in sustainability by addressing emerging concerns about brownfields, as well as abandoned, derelict sites, especially sites where the industrial land use changed several times. He established the long-term relationship of industry and environment — adding a time component to our the state of knowledge about what was toxic, how wastes were managed, what was the technology for managing wastes, and what was the regulatory framework then.

 

Later Colten co-authored “The Road to Love Canal: Managing Industrial Waste before EPA.” Today he is Carl O. Sauer Professor of Geography, Louisiana State University.

VIDEO 3: Gary Miller, the center’s first assistant director, spoke about the center’s research program. Up to this day, the mandate of ISTC is to provide 1) research, 2) technical assistance, and 3) public information about hazardous materials and other contamination threats. Miller said over 30 years the center has funded well over 200 studies, all available online.

 

Large contaminated sites in Illinois, such as Waukegan Harbor, Lake Calumet and industrial sites near Rockford got a lot of attention in those first years.  At that time a lot of work was necessary to establish the toxicity of contaminants present at those sites,  including some of the earliest studies of PCBs in the environment.

 

Other important research focused on waste issues such as improved landfill design and modeling of groundwater contamination from landfills. The early years also produced a comprehensive inventory of Illinois landfills that is still in use today. He added that the center also helped pioneer remediation, stabilization, and clean-up techniques through demonstrations and analysis.

VIDEO 2: David Thomas, the founding ISTC director, joined in May, 1985. During his presentation he looked back to the early days of Illinois’ hazardous waste center. When President Jimmy Carter declaired a federal health emergency at Love Canal, the problem of hazardous waste management had become a front burner concern nationwide. Previously working at an engineering firm, Thomas could see the concern grow as he saw more and more of the firm’s work had to do with hazardous waste.

 

As an U of I alumnus, Thomas was delighted Illinois had proposed the new hazardous waste center for Champaign. He also relished the job as a way to delve full-time into the interesting and important challenges of the hazardous waste. During his talk, Thomas discusses the legislative mandate of the center and its early efforts to organize a scientific response to the problems.

 

Thomas and original Assistant Director Gary Miller studied design of modern research labs around the nation to guide the development of the center’s research laboratory capabilities. Thomas noted with satisfaction that ISTC’s focus has effectively evolved to remain relevant in the rapidly changing field.
