DSM offers the biofuels industry a broad range of yeast and enzyme solutions that enhance starch, fiber and biomass conversions. For starch conversion our yeast is tailored to provide a consistent increased ethanol yield while significantly reducing glycerol production. For fiber conversion our enzyme formulation maximizes hydrolysis with an enhanced liquefaction capability and our yeast can convert all available sugars at a high rate including glucose, xylose and arabinose. For biomass conversion we offer both high performing yeast and enzymes solutions for multiple feedstocks and our POET-DSM Advanced Biofuels joint venture operates a commercial-scale production facility for cellulosic bio-ethanol in Emmetsburg (Iowa, USA) known as Project Liberty.
Project Liberty processes corn-crop residues through a bioconversion process (using enzymatic hydrolysis, followed by fermentation). The facility is the first and to date, only, commercial-scale producer of so-called ‘2G’ (second generation) cellulosic ethanol in the USA. At full capacity the facility will process 770 tons of corn cobs, leaves and husks daily, producing 20 million gallons of cellulosic ethanol per year, later ramping up to 25 million gallons per year.
An on-site enzyme manufacturing facility is also under construction at Project Liberty to improve the environmental impact of the production process significantly; no more stabilizers or other chemicals will be required for enzyme transportation.
