POET-DSM plans on-site enzyme manufacturing facility at Project Liberty
Plant has achieved 70 gallon per ton conversion rate
POET-DSM Advanced Biofuels will build an on-site enzyme manufacturing (OSM) facility in Emmetsburg, Iowa, pending state and local approvals.
The facility will be integrated into the Project Liberty technology package, replicable in future facilities. For Project Liberty, the OSM will directly pipe enzymes into the Liberty production process without requiring downstream processing, stabilizers and other chemicals required for enzyme transportation.
New enzymes developed by DSM are also expected to improve effectiveness of the enzyme mix, further reducing costs for the process. CRB has been awarded the contract for the design, engineering and construction management. Basic engineering is complete, and construction is expected to begin in late spring or early summer.
Project Liberty is a cellulosic ethanol plant that uses corn cobs, leaves, husk and some stalk to produce renewable biofuel. Over the last 18 months significant design improvements have been made to the plant and further investments to improve yields and make the process more consistent and reliable. The facility is producing at a rate of 70 gallons per bone-dry ton of biomass, near the target conversion rate, and is currently in a ramp-up phase.
“Enzymes for cellulosic ethanol have been improving dramatically in recent years, and this is another leap delivered by our partner DSM in both cost and performance,” POET President and COO Jeff Lautt said. “It will be a valuable addition to POET-DSM’s integrated licensing package.”
“We have reached some important production thresholds in recent months. This gives us the confidence to move to this next level of technology development,” Atul Thakrar, President DSM Bio-based Products & Services said. “The startup and ramp-up of Project Liberty have provided valuable experience for developing a cost-effective process that can be replicated across the U.S. and world.”
About POET-DSM Advanced Biofuels, LLC
POET-DSM Advanced Biofuels, LLC, is a 50/50 joint venture between Royal DSM and POET, LLC. Based in Sioux Falls, South Dakota, the company is a cooperative effort of two innovators that provides a key to unlocking the opportunity of converting corn crop residue into cellulosic bio-ethanol. Built on the strengths of both companies, the joint venture has a critical mission: to make cellulosic bio-ethanol competitive with corn bio-ethanol, the most competitive renewable liquid transportation fuel on the US market today. Drawing on the deep expertise and experience of POET and DSM in different areas of converting cellulosic biomass into bio-ethanol, POET-DSM Advanced Biofuels has built its first commercial-scale plant co-located with POET Biorefining – Emmetsburg in Emmetsburg, Iowa. Based on this plant, the JV plans to globally license an integrated technology package for the conversion of corn crop residue to cellulosic bio-ethanol. More information: www.poetdsm.com.
POET, one of the world’s largest ethanol producers, is a leader in biorefining through its efficient, vertically integrated approach to production. The 29-year-old company has a production capacity in excess of 1.75 billion gallons of ethanol and 9 billion pounds of high-protein animal feed annually from its network of 28 production facilities. POET, through its joint venture with DSM, operates a commercial-scale cellulosic ethanol plant in Emmetsburg, Iowa. For more information, visit www.poet.com.
