Koch unit invests in new biofuels plant

Flint Hills Resources Renewables, the ethanol and biofuels subsidiary of Koch Industries, has formed a joint venture, Dounix, with biofuels company Benefuel to develop biodiesel refineries in the United States, according to a news release from Benefuel.

Duonix is retrofitting a mothballed 50-million-gallon-per-year biodiesel plant in Beatrice, Neb, which Flint Hills Renewables bought out of bankruptcy in 2011. Flint Hills Resources will operate the plant.

The plant will use Benefuel’s patented Ensel refining technology, which, according to the release, can improve profitability and reduce waste.
