WATCH: Randall Stuewe, Darling Ingredients' CEO, give an update at our DGD facility located outside New Orleans, Louisiana
Our Diamond Green Diesel (DGD) plant, a joint venture between Darling Ingredients and Valero Energy Corp., processes approximately 15% of the animal fats and distiller & used cooking oils generated in North America.
- Todays annual capacity is 275 million gallons of renewable diesel
- After Diamond II is complete in late 2021:
- It will process approx. 35% of North America's waste fats and oil
- It will produce over 675 million gallons of renewable diesel
- The annual GHG emission equivalency will remove 1.89 million cars from the road compared to a petro-based diet
DAR PRO Solutions transforms used cooking oil and animal meat by-products into valuable new resources that contribute to a more sustainable world.
The remaining oils, fatty acids, proteins, meals, and minerals are used as nutritional ingredients for livestock feed and pet food, or for a variety of industrial and commercial purposes. Products containing our sustainable ingredients can be found in homes across the world.
Read more about how we repurpose what others would consider waste in our blog article "A Second Life for Meat Scraps & Used Cooking Oil."
Anticipating a rising need for sustainable fuel solutions among the world’s growing population, Darling Ingredients, DAR PRO’s parent company, pioneered the commercial production of biodiesel from recycled animal fats and used cooking oils.
Our Biodiesel Production
Kentucky biodiesel: Our Butler, KY, biodiesel plant began operating in the 1990s. It was the first commercial operation in the U.S. to produce clean, efficient biodiesel from animal fats and used cooking oils. Our biodiesel meets all ASTM D6751 specifications and reduces emissions by up to 85% compared to petroleum diesel.
Quebec biodiesel: We were also the first company in Canada to operate a commercial animal fat and used cooking oil biodiesel facility. The Darling Ingredients Canadian brand, Rothsay, produces approximately 45 million liters of biodiesel per year, reducing greenhouse gas emissions by up to 85% as compared to petroleum diesel.
Louisiana renewable diesel: In 2013, we began production at our Diamond Green Diesel facility outside of New Orleans. This is the largest operation in North America to produce renewable diesel (or "green diesel") from recycled animal fats, used cooking oils and distiller oils. Renewable diesel, unlike biodiesel, is produced in a way that yields a biofuel chemically identical to petroleum diesel, yet is low carbon and emits up to 85 percent less greenhouse gases. This clean, efficient renewable diesel can be dropped into the existing pipeline for distribution to diesel retailers or sold as a low carbon alternative to petroleum diesel.
Renewable diesel, unlike biodiesel, is produced in a way that yields a biofuel chemically identical to petroleum diesel, but...
- Is a low carbon biofuel that emits up to 85% less greenhouse gases than petroleum diesel
- Has no cold flow issues or transportation restraints
- Renewable diesel can be dropped into the existing pipeline for distribution to diesel retailers or sold as a low carbon alternative to petroleum diesel
- Biodiesel's cetane varies depending if it's sourced from cooking oils or animal fats, scoring between 46 to 60
- Renewable diesel benefits from its higher cetane rating between 75 and 90, versus 48 and 55 for petroleum diesel
- Burns in a cleaner more complete way compared to petroleim diesel
