An Indiana town is looking at a plan that would turn sewer sludge into biodiesel. This article from the Princeton (IN) Daily Clarion says that city is negotiating a contract with Terre Haute, just up the road, to haul away the sludge and make it into the green fuel.
Sewer plant superintendant Charlie Woodruff said Terre Haute works with a company that makes biodiesel out of the sludge.
He estimated that Princeton generates about 10,000 to 14,000 gallons of sludge per day.
Hurst said a report will be presented Jan. 20 to the board, comparing the cost of contracting for the sludge disposal with Terre Haute to the cost of the chemicals the city needs to use to try to mitigate the stink that wafts away from the plant on Richland Creek Drive, toward homes and local businesses.
According to the Terre Haute Tribune Star, that city is expected to produce 12 million gallons of biodiesel from its sludge-to-biodiesel program.
