FOG powers treatment plant in Indiana

Recycled grease fed to a digester provides 20 percent of the power at wastewater treatment plant in West Lafayette, Indiana.

Collected fats, oils and grease (FOG) that feeds an anaerobic digester is providing 20 percent of the necessary power at a wastewater treatment plant in West Lafayette, Indiana.

According to a report by WLFI TV in Lafayette, Indiana, the city of West Lafayette, Indiana, has been collecting used grease and cooking oil for recycling since 2010.

West Lafayette Utility Director David Henderson says the collected FOG is fed to anaerobic digestion tanks at West Lafayette’s Water Resource Recovery Facility. Those digesters create methane in what Henderson calls a combined heat-and-power (CHP) process that helps power a generator used to produce electricity at the plant.

The city has FOG collection containers available to accept dropped off oil and grease at any time.
