On-Site Food Waste Composting Closes The Loop
Food residuals are collected in red barrels at the dining and residence halls (1). Yard trimmings and food residuals are blended in a mixer (2) and then loaded into a rotary drum (3). After a 3-day retention time, material is conveyed to a composting area (4), where windrows remain for 4 weeks prior to curing.

Pre and postconsumer food scraps from dining and residence halls are mixed with yard trimmings and processed in a rotary drum followed by windrow composting.
