Akron, Ohio [RenewableEnergyAccess.com] The City of Akron, Ohio has opened a facility designed to produce electricity from biogas. Generated by the decomposition of sludge from the City’s wastewater treatment plant, biogas is now the fuel that powers a 335-kW engine-driven generator.
Akron and KB Compost constructed the $7 million plant to be similar to the 200 or so operations developed by the Schmack in Asia and Europe. The city’s sludge plant will be one of the first in the country to create electricity using high-solids anaerobic digestion.
The initial biogas operation is designed to handle 5,000 dry tons of solids annually, or about one-third of the 15,000 dry tons produced annually at the wastewater treatment plant. Akron’s system has been developed by Schmack Biogas AG.“We will save money by not having to purchase an equivalent amount of electricity, thus offsetting some of the $1.35 million we spend annually for electricity here,” said Akron Mayor Donald Plusquellic.
