The Delphi Township wastewater treatment plant, is among just three in the nation that produce electricity from methane gas generated during the sewage treatment process, WILX reports.
As sludge is broken down by bacteria it produces methane gas which powers a turbine to generate electricity.
Sandra Diorka, director of public services for Delhi Charter Township told WILX that this process is expected to save the township $70,000 per year in energy costs.
The Ingham County township is actively exploring other ways to save, or generate, energy in the waste treatment process.
The township is working on a study with the Lansing Board of Water and Light to see if they will be able to use some of the class A solids produced during this process for energy. Diorka says once the product is dried, it may be useful as a substitute for coal in their coal burning generators.
