“Mr. Sewer” is a multi-stage waste-to-biofuel production system under development by ISTC. This system can remove both organics and nutrients in municipal wastewaters and turn them into renewable energy resources. Processing of the wastewaters is combined with algae farming in a way that amplifies the energy production while cleaning the water for potential reuse applications. The nutrients support algal growth and the algae are then harvested for use in biofuel. Amplified by the sun's energy and continuous nutrient reuse, an optimized system can harvest three to ten times the energy contained in the waste water. Calculations based on a commercial-scale demonstration plant on the University of Illinois campus indicate the technology is well-suited to generate fuel/revenue from wastes at the scale of a small city or a self-contained military installation.
