Coskata's semi-commercial facility represents the successful scale-up of Coskata's feedstock flexible biofuel technology, preparing the way for rapid commercialization of the world's first commercially viable cellulosic ethanol facility.

The facility produces ethanol from numerous non-food based feedstocks, including wood biomass, agricultural waste, sustainable energy crops and construction waste. It is a "minimum scale engineering" facility, meaning it is of sufficient size to allow scaling to 50 million and 100 million gallon Coskata facilities.

The semi-commercial facility is located in Madison, Pennsylvania, approximately 30 miles outside of Pittsburgh. It is co-located at Westinghouse Plasma Corporation (WPC). It was officially unveiled in October of 2009.
