Anaerobic digestion is a biological process during which microorganisms break down organic material in the absence of oxygen to produce biogas containing a high percentage of methane. The methane can then be used to generate electricity and/or heat. Depending on the type of digester and feedstock, additional useful outputs may be produced, such as a soil amendment and compost.
To better understand the technical and economic issues associated with such a project, the City engaged with Tighe & Bond to conduct a comprehensive Feasibility Study of Anaerobic Digestion for biogas at the Wastewater Treatment Plant on Gosselin Drive. The Feasibility Study has been funded with a grant from the MassCEC, through its Organics to Energy (OtE) program.
