Technology Brief	The VERBIO Nevada Biorefinery, located in Nevada, Iowa (USA), is the first industrial scale renewable natural gas (RNG) facility in North America using agricultural residues as its feedstock. The plant is 100% owned by VERBIO North America Holdings Corporation. RNG production from corn stover began in December 2021 with the completion of Phase I, at a capacity of 7 million ethanol gallons equivalent (EGE) per year. Upon completion of Phase II in the 4th quarter of 2022, the site will begin operating as a biorefinery, producing 60 million gallons of corn-based ethanol and an additional 19 million (EGE) of RNG from stillage. The integration of RNG and ethanol production, unique to VERBIO, incorporates advanced operational technology currently practiced at the company’s facilities in Germany. The process also yields humus, a soil amendment, and organic fertilizers.
Additional Information	Following the merger with DOW and the decision to leave the biofuels business, DuPont put the 30 MMgy (90,000 tonnes/yr) cellulosic ethanol plant in Nevada, Iowa, up for sale in the autumn of 2017. In November 2018 it was sold to Verbio North America Corp., the U.S. subsidiary of German bioenergy producer Verbio Vereinigte BioEnergie AG. Verbio is planning to convert the facility to produce renewable natural gas (RNG) from straw.
