Compost collection bins are available by the Chemistry Loading Dock. Composting diverts matter from landfills and turns it into a resource, such as nutrient-rich soil or biogas. Composting food waste also reduces methane production, a prominent greenhouse gas that contributes greatly to global climate change.
Items that go in the containers for composting on campus are items that can break down in nature relatively easily or under the right conditions. If you are interested in learning how to compost at home, get in touch with ASUCD Project Compost, located behind the Bike Barn!
