How Fats and Used Cooking Oils are Low Carbon Renewable Resources

DAR PRO Solutions transforms used cooking oil, fats and grease trap materials into valuable new resources that contribute to a more sustainable world. We process organic meat byproducts and used cooking oils to create biodiesel, renewable diesel, and nutritional ingredients for livestock feed and pet food. The processed oils, fats and fatty acids are also used for industrial and commercial purposes, and can be found in a variety of consumer products used in homes across the world.

Our company is answering the world's need for sustainable, low carbon fuels. 

Our Diamond Green Diesel plant, a joint venture between Darling Ingredients and Valero Energy Corp., will double its annual capacity to 275 million gallons of renewable diesel by the end of summer 2018.  We've also announced that we are investigating an additional expansion to again double production to 600 million gallons by 2021.  WATCH Randall Stuewe, Darling Ingredients' CEO, give an update at our DGD facility located outside New Orleans, Louisiana.

Domestic biofuel production provides US jobs and reduces fuel imports

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.

Kentucky biodiesel: Our Butler, Ky., biodiesel plant began operating in the 1990s, and it still produces clean, efficient fuel that 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 distilled oils. Renewable diesel, unlike biodiesel, is produced in a way that yields a biofuel chemically identical to petroleum diesel, yet emits up to 85 percent less greenhouse gases. This clean, efficient, low carbon renewable diesel can be dropped into the existing pipeline for distribution to diesel retailers or sold as a low carbon alternative to petroleum diesel. The DGD facility currently produces 160 million gallons of renewable diesel annually, and is on track to expand to 275 million gallons by the end of summer 2018.

Creating a Better Future with Sustainable Energy

The opportunity to use used cooking oils and animal fats as feedstock and renewable energy alleviates the demand on the world’s dwindling energy resources. Darling Ingredients has done more than any other company in the world to elevate the value and usefulness of used cooking oil and animal fats.

When we process the meat byproducts we collect from our customers, we contribute to maintaining a healthy environment in three important ways:   

  • We divert carbon and nitrogen away from the soil, surface waters, groundwater and the atmosphere through effective recycling.

  • We transform the carbon and nitrogen we capture into useful products, which reduces the production of greenhouse gases that result when new products are produced and later discarded.

  • We offer a safer and more efficient alternative to landfill, incineration or composting of inedible meat by-products or farm mortalities.
