Cellulosic ethanol is a renewable liquid fuel produced from readily available biomass feedstock sources. Cellulose is the most abundant organic compound on earth and is found in virtually all forms of biomass. Vercipia's cellulosic ethanol production process uses technology based on advanced, proprietary enzyme science that reduces the cost of production and enables the use of a wide variety of biomass feedstocks relative to first generation ethanol production.
