**UPDATED to add Bergen Record story and editorial** The folks who run the municipal water treatment plant in Ridgewood, NJ came up with a better way than just burning off the methane gas created in the process of treating waste. They added used restaurant grease to the mix and a privately financed system to turn much of the gas into electricity. It powers their operations at discount prices.

Mike Schneider of NJTV News visits the plant and reports on the innovation above.
