January was a record month for processing food waste at West Lafayette's waste water treatment plant.
Utility director Dave Henderson says 36-tons was collected from the Purdue Memorial Union and dining courts on campus.
He says along with the 26,000 pounds of fats, oils, and grease that were processed in January, the plant was able to generate 20% of the electricity needed for its operation.
Henderson says that saved the city more than $5,000.
He says the utility will continue to look for ways to increase the amount of power the plant produces in-house.
