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.

Provides an easy-to-use method of disposing food waste in an environmentally efficient manner.

Cost savings
Eliminates the need to transfer food waste.

Results in procedures to safely dispose food waste without sending it to the landfill.

Eliminates smells, mess, and pests from the trash bins and waste areas.

Provides statistics on usage, diagnostics, and service schedules.

The biodigesters that Dining Services use can break down fruit, vegetables, nuts, meat, bread, fish, and cheese, allowing the university to significantly reduce the total food waste it produces.
