Wastewater Treatment

Wastewater, traditionally a cost center for businesses and governments, is now becoming an asset, thanks to smart entrepreneurs who are turning waste into biofuel or renewable energy. Pasteurization Technology Group, a San Leandro-based start-up, uses biogas produced in water treatment to power a turbine that produces renewable energy. That energy can be used on-site or sold to utilities. The exhaust produced from the turbines then pasteurizes the wastewater, purifying it so it can be reused.
