Welcome to Diamond Green Diesel

In a joint venture called Diamond Green Diesel, Diamond Alternative Energy LLC, a subsidiary of Valero Energy Corporation, partnered with Darling Ingredients Inc. to build an 18,000-barrel-per-day renewable diesel refinery near the Valero St. Charles Refinery in Norco, Louisiana, to process animal fats, used cooking oil and inedible corn oil 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, a leading global developer and producer of sustainable natural ingredients from edible and inedible bio-nutrients, it is the first move 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 renewable diesel facility near St. Charles is located next to Valero's existing refinery infrastructure.
  • The plant is capable of annually converting approximately 2.3 billion pounds of ​​rendered and recycled material​​ into more than 275 million gallons of renewable diesel, with a planned expansion to 675 million gallons per year by late 2021.

  • The product is compatible with petroleum-based diesel fuel and can be shipped by pipeline, and used by exisiting engines and infrastructure. 

  • Importantly, the fuel has a carbon lifecycle low enough to meet the most stringent low-carbon fuel standards.
