University of Washington Seattle Campus Composting Program

A brief description of the innovative policy, practice, program, or outcome:

In lieu of paying to dispose of leaves and post-consumer coffee grounds to a corporate composting facility, as well as to reduce the hydrocarbon emissions to transport the material off-site, University of Washington Grounds Management developed a way to capture part of that leaf and coffee waste stream and turn it into nutritious soil amendments for landscaping beds throughout campus and for use by the UW farm. This in-house composting program is a collaboration between UW Housing & Food Services, UW Recycling & Solid Waste, and Grounds Management. Half of the cost of implementation was funded in part through the Campus Sustainability Fund, an internal student directed funding program that supports sustainability projects all over campus. About 2000 lbs. of post-consumer coffee are diverted every week and 55 tons of leaves are diverted each season towards this program which started in 2012. Arbor chips from hazardous campus tree removal is also utilized in this mixture, increasing air circulation in the pile. These three components produce a nutrient rich product that is utilized as both an organic soil amendment and planting bed mulch. The perfect complement to the picturesque landscape of the University of Washington Seattle.
