BALTIMORE (AP) — Baltimore city officials are hoping to create even more power from sewage at a wastewater treatment plant.

The city’s Back River plant already burns methane produced by the sewage to create electricity. Now under an agreement approved Wednesday by the Board of Estimates, carbon dioxide from the plant’s exhaust will be used to grow algae that will be turned into fuel.

The one-year project is expected to cost $255,000 and is being paid for with federal stimulus funds.

Dayton-based Hytek Bio will grow the algae and turn it into a fuel that can replace heating oil used in city boilers and diesel used in city vehicles.
