Two companies said Wednesday that they have developed a method for turning sewage sludge into ethanol.
Israel-based Applied CleanTech and Marlborough, Mass.-based Qteros created a joint development project that combines sewage treatment technology and a microbial process for converting biomass into ethanol.

Many researchers have been studying ways to extract usable energy from sewage sludge but there are not any commercial operations that make liquid fuel.
Applied CleanTech's core technology, which is already used in treatment plants, extracts the biosolids from raw sewage, which is a way to reduce the overall amount of wastewater that needs to be treated.
In its partnership with Qteros, the biosolids are used as a feedstock to produce ethanol. Qteros, founded
