Washington University in St. Louis has composed 160,000 lbs. of waste since August 2010, 97,000 lbs. last year alone, using an outside company that takes its organic waste and sell it back as compost that is used in campus landscaping. Materials composted at the facility operated by St. Louis Composting include food waste, paper napkins, cardboard pizza boxes, tea bags, sugar packets, compostable plastic items, wood stir sticks and chopsticks.
WUSTL Dining Services disposes of pre-consumer food waste into compost buckets in its production facility. Post-consumer waste collection depends on location. At the Bear's Den, students can scrape compostable waste off their plates and into bins before placing them on the dish return. At the Danforth University Center, dining services staff also scrapes food waste from trays that are placed on the dish return. Ibby’s Bistro also collects all food left on customers’ plates into compost buckets.
