U.S. biofuel company Qteros says it has created the first commercially-viable technology for creating ethanol from the materials found in municipal waste (what we would call sewage).
The company has teamed up with an Israeli bio-tech company, Applied CleanTech, to use one of Applied's technologies to complete the process of making ethanol. The technologies have the potential to save municipal waste water plants a lot of money by giving them a way to create revenue by selling energy.
