World's Second Largest Renewable Diesel Producer

Diamond Green Diesel LLC (DGD) is a joint venture between subsidiaries of Valero Energy Corporation and Darling Ingredients Inc. DGD is the largest renewable producer in North America and the second-largest in the world.

The fuel produced at our facility reduces greenhouse gas emissions by up to 80% compared with traditional diesel fuel.

The new 470 million gallons per year renewable diesel plant near Valero's Port Arthur, Texas refinery began operations in late 2022, increasing Diamond Green Diesel's total production to approximately 1.2 billion gallons of renewable diesel. 

Our renewable diesel is produced from sustainable low-carbon feedstocks, such as used cooking oil, inedible animal fats derived from processing meat fats and fuel-grade corn oil. Darling processes 10% of the world’s inedible meat by-products and is the largest collector and processor of used cooking oil in North America. 

In addition to this integrated supply chain, both Darling and Valero bring expertise to the operation of Diamond Green Diesel. Darling has extensive experience in pretreating the feedstocks for further processing, and Valero has extensive experience in converting the pretreated feedstock to renewable diesel and marketing transportation fuels to the marketplace.

This combination of an integrated feedstock supply, and rendering and refining expertise, is unique in the renewable diesel industry and enables us to efficiently produce and market superior low-carbon fuels.
