Energy
Recovery
During anaerobic digestion, digester gas is produced which is approximately 60-70
percent methane, a valuable fuel. This digester gas is used to co-generate
electrical power
using two 150 KW biogas engine generators housed in the Energy Recovery Building. Waste heat, a
by-product of power generation, is recovered from the engines and exhaust
to heat the digester.The electricity and heat which are produced by the cogeneration
system are utilized in the plant to reduce purchased electricity and natural gas.
Electricity produced by the generators is fed into the plant electrical distribution
system for use where needed. Heat from the gas engines is recovered and used for heating
the Digester and the Energy Recovery Building.
Approximately 35% of the plants electrical need is met by the onsite
generation of electricity.
