Matthew Stone Teysha Technologies a company’s technology builds on the principles of anaerobic digestion and the fischer-tropsch (F-T) process to convert biodegradable waste into liquid fuel. Traditionally, this has been an energy-intensive process that has yielded fuels unsuitable for use without further blending. With Renovare’s technology, the process is designed to be self-sustaining from an energy conservation perspective, with the water and gas produced during the F-T process used to power the system.
