Campus Building Waste Characterization & Opportunity Assessment
The Illinois Sustainable Technology Center (ISTC) Technical Assistance Program’s Zero Waste team conducted a Campus Building Waste Characterization & Opportunity Assessment (full report and executive summary available in the related documents area) to help F&S identify and measure the types of landfill (trash) and recycling material generated on campus.
The audit involved hand-sorting materials from landfill-bound and recycling waste stream samples into predetermined material categories (e.g., cardboard, mixed paper, plastic bottles, other plastic containers, etc.) and weighing the amounts of each category present in the samples. Calculating the percentage of a sample waste stream represented by each material group, in turn, identified specific opportunities for waste prevention, reduction, and diversion.
Due to the size and volume of waste and recycling generated on campus, sorting all materials is not feasible. Thus, an “activity zone” approach was used for the audit. This involves selecting a representative set of buildings across campus based on the classification of a building according to its primary function and service. For this waste audit, four activity zones and eight respective buildings were 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
Summary of Findings
Landfill Analysis
Within all 1742.3 pounds of landfill-found trash sorted across activity zones in this audit, only 18.9 percent had no other fate than being sent to the landfill. The avoidable amount was estimated to be 34 percent. Nearly 23.1 percent of all landfill waste was paper towels, which could be composted, recycled through a special program, or replaced by electric hand dryers instead of being trashed. Currently recyclable materials represented 12.9 percent of the waste stream, or 224.76 pounds of material. Another 17.1 percent might be recycled with expanded recycling programs. Finally, 17.1 percent was compostable.
Recycling Analysis
Within all 1065.7 pounds of material from recycling streams across activity zones sorted in this audit, 81.4 percent was correctly recycled; 62.3 percent of material sorted was cardboard. 18.6 percent is not currently accepted and is considered contamination. Liquids were the largest (by weight) material category contributing to contamination at 2.6 percentage of materials sorted. Liquid contamination can ruin even correctly recycled items; paper and cardboard must be clean and dry to be eligible for baling and sale as commodities.
Improvement Strategies
Based on operations at those buildings, 39 recommendations grouped into seven themes were identified in the assessment. You can read the full report, as well as the executive summary, on this page under “Documents.” Numerous hyperlinks within the recommendations are available in the PDF file.

Education & Outreach
Number | Strategy | Activity Zone | Impact | Responsible Party |
1 | Expand tours of the Waste Transfer Station to help the campus community better understand the recycling process. Require all existing BSWs (F&S coordinated & auxiliary) to tour the WTS. Make this part of onboarding new BSWs. Continue to advertise and facilitate WTS tours for faculty, staff and students. | CW | High | F&S, Auxillaries |
2 | Communicate bag color standards to all facility managers and BSWs (including auxiliary) via BSW manuals, training, direct communications, etc. This effort should be ongoing, and efforts should be made to gather feedback from BSWs. | CW | High | F&S, Auxillaries |
3 | Meet with departments/units to determine whether bag color standard is being followed in their buildings. Where it is not, work to understand and address barriers to implementation with those units and other relevant stakeholders (e.g. Purchasing, Central Stores, etc.) to address those barriers. | CW | High | FMs, Stores |
4 | Explore use of the Illinois App for sharing information on waste management and recycling procedures, barriers, challenges, lessons learned, linkage to the Recyclopedia (when released), etc. Different “groups” within the app could be formed for different segments of the campus community for targeted messaging and peer-to-peer networking and information sharing (e.g. BSWs, staff, faculty, undergraduate students, and graduate students). | CW | Medium | F&S, iSEE |
5 | Create a separate social media presence for F&S zero waste efforts to increase visibility of recycling, reuse, and diversion information on campus. | CW | High | F&S |
6 | Use campus digital signage network, new and existing e-bulletins, and social media to: Share waste reduction and recycling best practices with campus community members and dispel misconceptions. Provide instructions on how to contact F&S with questions (e.g., via recycling@illinois.edu). Inform campus community members about the iCAP portal. Consider presentations, videos, or online tutorials to help people understand how to navigate and submit suggested additions and/or revisions. | CW | High | F&S |
7 | Explore strategies to address liquid contamination in the recycling stream. Modify labels and signage on all collection bins for plastic beverage bottles and cans to instruct individuals to empty liquids before disposing of containers. Consider inclusion of QR codes for building-specific maps of for restrooms, water fountains, or other locations where liquids could be poured out. Develop an outreach campaign to underscore the role of liquids as a major contaminant in recycling and the importance of keeping liquids out of recycling bins.
