In a joint venture called Diamond Green Diesel, Diamond Alternative Energy LLC, a subsidiary of Valero Energy Corporation, partnered with Darling International Inc. to build a 10,000-barrel-per-day renewable diesel refinery near the Valero St. Charles Refinery in Norco, La., to process recycled animal fat, used cooking oil, and other feedstocks into renewable diesel fuel.

  • Through Diamond Alternative Energy, the effort marks Valero’s first advanced biofuels production, complementing its other alternative-energy efforts in ethanol and wind energy.
  • For Darling, the nation’s leading rendering and recycling company serving the food industry, it is the first move into into the mass scale production of renewable diesel.
  • Fuels produced in the U.S. from biomass feedstocks can reduce greenhouse-gas emissions, improve energy security and bring jobs and investment.
  • The facility at St. Charles is located near the existing refinery infrastructure.
  • The plant is capable of annually converting 1.1 billion pounds of fat into more than 136 million gallons of renewable “green” diesel.
  • The product is compatible with petroleum-based diesel fuel and can be shipped by pipeline.
  • Importantly, the fuel has a carbon lifecycle low enough to meet the most stringent low-carbon fuel standards.
