What is Compost?

Compost is nature’s way of recycling biodegradable material such as: leftover food scraps, paper and cardboard products, and plant waste. The process of composting helps to reduce the amount of waste that goes into our landfills by reusing and recycling food waste to create nutrient-rich soil/humus used for our gardens and agriculture.


Items accepted

Food waste & solid paper products

Items not accepted

Glass, plastic, metal, aluminum foil & styrofoam

Where does the USU's compost go?

Compost waste from the USU is picked up daily by custodial staff and taken to the compost compactor at the USU loading dock, and picked up by the waste hauler, Athens. The collected material is then brought to the compost facility, American Organics, where it is processed into nutrient rich compost for agricultural end users.

What materials can be composted?

The composting program in the USU is extremely user friendly thanks to our partnership with American Organics. All food waste; soiled paper products, and other biodegradable materials, are accepted into the compost bins. See the ‘What is compost?’ section of this FAQ page for graphic representations.
