Akron starts making electricity from sludge

by WKSU's KAREN SCHAEFER


Reporter
Karen Schaefer
 
The city of Akron has begun making electricity from sewer sludge. A new German technology " the first of its kind to be used in the U.S. " captures the biogas given off by decomposition of the sludge to produce electricity, enough to power the plant and several hundred homes.

This diagram shows the process in which Akron will turn sludge into biogas
This round chamber - called the Euco - is where primary sludge treatment takes place
The second rectangular chamber furthers breaks down the sludge, which gives off biogas that can be burned to produce electricity
These rows of compost bins will continue to be used for at least the next 18-months, while Akron evaluates the biogas plant's performance
Brian Gresser is the plant administrator.  He says the new biogas plant will save the city money
Annette Berger, vice president of operations for KB Compost, helped build the plant, using German designs
