Question: 

What process has CenUSA Bioenergy selected to produce biofuels from perennial grasses?

Answer: 

We have selected advanced pyrolytic conversion to produce biofuels from perennial grasses. Pyrolysis is the thermal decomposition of biomass in the absence of oxygen to produce an energy-rich liquid called bio-oil, a flammable gas mixture, and a carbon-rich and nutrient-rich solid called biochar.
