Wisconsin ethanol plant wins approval for biofuel credits
A Wisconsin ethanol plant won approval to generate biofuel credits, adding compliance value beyond fuel sales. EPA’s pathway list sets the federal framework for RIN-eligible gallons.

The U.S. Environmental Protection Agency approved a Wisconsin ethanol plant to generate biofuel credits.
The U.S. Environmental Protection Agency’s Approved Pathways for Renewable Fuel, published Dec. 2, 2022, is the federal gatekeeper for renewable fuel pathways under the Renewable Fuel Standard. The pathway list determines which fuels and production processes can generate Renewable Identification Numbers, and approval can turn a gallon of ethanol into a compliance asset as well as a transportation fuel.
Legislative records from 2008 reference a Special Committee on Domestic Biofuels and ethanol and biodiesel tax credits. State Rep. David Steffen testified on Sept. 16, 2025, for Assembly Bill 222, which would create a $1.50-per-gallon SAF production tax credit, and State Sen. Romaine Robert Quinn testified on Oct. 7, 2025, for Senate Bill 284 on SAF production credits.

ClonBio Group Ltd. acquired Wisconsin’s largest ethanol plant in Jefferson in 2022 and planned to transform it into an advanced biorefinery. The Wisconsin BioFuels Association puts ethanol’s greenhouse gas reductions at up to 57% compared with gasoline. About 20 Wisconsin stations now offer higher blends such as E15, E20, E25, E30 and E85.
