USPTO issues patent to Syngenta Participations for 'systems and processes for producing biofuels from biomass'; patent filed on Feb. 3, 2009

ALEXANDRIA, Virginia , February 4, 2014 () – United States Patent no. 8,641,910, issued on Feb. 4, was assigned to Syngenta Participations AG (Basel, Switzerland).

"Systems and processes for producing biofuels from biomass" was invented by Gary Wietgrefe (Sioux Falls, S.D.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Systems and processes for converting bulky lignocellulosic biomass to high density biomass products, including biofuels, are described. The systems and processes relate to treating freshly harvested plant materials, generally at or in close proximity to sites where the plant materials are harvested, to effect saccharification, alcoholic fermentation, or simultaneous saccharification and fermentation, thereby providing a liquefied biomass. The liquefied biomass is extracted to provide liquid extracts comprising biomass-derived water and water soluble biomass saccharification and fermentation products, including fermentable sugars and alcohols. The liquid biomass extracts can be transported via pipeline to other locations for fermentation, further saccharification, and/or purification to provide biofuel. Alternatively, the liquefied biomass can be used to prepare a biomass slurry that can be transported via pipeline."

The patent was filed on Feb. 3, 2009, under Application No. 12/866,134.
