Diamond Green Diesel, the renewable diesel production joint venture between Valero subsidiary Diamond Alternative Energy and Darling International, has reached mechanical completion in US.
The new plant, with a capacity of around 9,300 barrel-per-day, will convert recycled animal fat, used cooking oil and corn oil into renewable diesel fuel, which meets low-carbon fuel standards.
Commenting on the development, Darling International chairman and chief executive officer Randall Stuewe said the joint venture will generate renewable diesel, which will have a potential to meet RFS2 biomass-based diesel mandate.
"Our partnership with Valero will benefit Diamond Green Diesel through multiple operational synergies," added Stuewe.
Darling International recovers and converts used cooking oil and commercial bakery residuals into valuable feed and fuel ingredients. These products are primarily sold to agricultural, pet food, leather, oleo-chemical and biodiesel manufacturers around the world.
Diamond Alternative Energy, which operates as a subsidiary of Valero Energy, develops biorefinery and specializes in biofuels.
