The anaerobic digestion plant will now begin taking in loose food and packaged food that will be de-packaged and slurried, with some material being recycled.

An anaerobic digestion (AD) plant at Crapo Hill landfill in New Bedford, Mass., the state’s first disposal site to house such a facility, is expanding.

The plant was built by Commonwealth Resource Management Corporation to digest food waste, biosolids, fats, oils and grease and to make biogas. The biogas is mixed with landfill gas, some of which is used to power the waste-to-energy (WTE) plant adjacent to the landfill while the majority is sold into the regional grid.
