Yes

A brief description of the pre-consumer food waste composting program:

Residential Dining and the Purdue Memorial Union (PMU) do not directly compost pre-consumer food waste. All Residential Dining facilities and PMU divert waste from the landfill through a cooperative agreement with the West Lafayette Waste Water Treatment Plant (WWTP). All pre-consumer waste collected is transported to the WWTP. At the WWTP the pre-consumer food waste is placed in an anaerobic digester which produces methane gas used to run turbines to produce electricity. Approximately 25% of the electrical needs of the WWTP are provided through this process.
