OP-19: Construction and Demolition Waste Diversion

Campus Recycling collects the following materials for diversion: • Single stream recycling: bottles, aluminum and metal cans, plastics #1-7, mixed paper, cardboard, milk cartons; • Source separated items include: Hardbound books, mixed rigid plastics, pallets/waste wood, and scrap metal; • Surplus office, lab and classroom furniture and equipment, Housing furniture, electronics, surplus mechanical and building materials and vehicles are stored at an off-campus warehouse. Approximately every two years, HSU holds a public agency give-away and public auction of these materials not reused on campus; • In addition to food waste and food soiled paper being collected at the main dining areas on campus, they are also collected at football games and other eventsin addition to strategic buildings on campus. Approximately 6 tons a year remains on campus for composting, while approximately 170 tons is currently shipped to a commercial composting facility. Although some recyclable and compostable material still finds its way into the trash bins, the University’s solid waste stream is comprised primarily of municipal solid waste, mixed residue, plastic and foam packaging, and non-recyclable campus consumables.
