Waste Management and MCE, formerly known as Marin Clean Energy, has opened a new landfill gas-to-energy plant at Novato’s Redwood Landfill. In other words, Marin’s trash is being turned into electricity — by using the methane gas generated by the landfill’s decomposing organic contents to power two massive reciprocating engines on site. Previously that gas just burned off into the atmosphere, raising greenhouse gas emissions. MCE now has a 20-year agreement with Waste Management to buy the electricity for customers. Above are some relevant numbers.
