The use of biodigesters at some dining services locations allows us to divert food waste from the landfill and reduce our carbon footprint.

Benefits of having biodigesters on campus can be summed up with the five C's.

Convenience of quickly digesting food waste on site with no odor or noise. Significant cost savings in reducing cost to dispose of and manage waste food. Compliance with safely disposing of our waste without sending it to the landfill. Increased cleanliness by eliminating smells, mess, and pests from our trash bins. And control by seeing statistics on usage, diagnostics, and service schedules.
