Our Plant

North America’s Largest Renewable Diesel Production Facility

At our 275 million-gallon-per-year renewable diesel plant, we process recycled animal fats, used cooking oil and inedible corn oil into renewable diesel fuel.

Our renewable diesel meets the most stringent low-carbon fuel standards.

With an integrated supply chain combining Darling's feedstock with Valero's production and marketing logistics, this dynamic partnership produced its first barrel of renewable diesel in 2013.

From an initial production capacity of 160 million gallons a year, we have expanded to our current 275 million gallons per year, and are in the construction phase to expand to 675 million gallons per year in 2021.

Valero and Darling continue to pursue growth in the low-carbon renewable diesel business, initiating an advanced engineering and development cost review for a potential new 400 million gallons per year renewable diesel plant near Valero's Port Arthur, Texas refinery. If the project is approved, operations are expected to begin in 2024, increasing Diamond Green Diesel's production capacity to more than 1.1 billion gallons per year.
