How Fats and Used Cooking Oils are Low Carbon Renewable Resources

DAR PRO Solutions transforms used cooking oil and animal meat by-products into valuable new resources that contribute to a more sustainable world.  Virtually 100% of the used cooking oil we collect is processed into low carbon renewable diesel or biodiesel at one of our three biofuel production facilities. About 50% of the meat by-products are processed into fats that are also used to create biodiesel or renewable diesel. What is left are oils, fatty acids, proteins, meals, and minerals that 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.

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

Our Diamond Green Diesel (DGD) plant, a joint venture between Darling Ingredients and Valero Energy Corp., processes approximately 1 out of every 6 pounds (or ~15%) of the animal fats and distiller & used cooking oils generated in North America.  In August 2018, DGD doubled its annual capacity to 275 million gallons of renewable diesel.  We are investigating a possible additional expansion that would more than double production to over 600 million gallons, targeted for completion in 2021.

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. 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. The DGD facility doubled expansion in August 2018 from 160 to 275 million gallons of renewable diesel annually, and is considering a proposed additional expansion that would more than double capacity to over 600 million gallons with an anticipated operational date in 2021.

Creating a Better Future with Sustainable Energy

The capability for used cooking oils and animal fats to be used as feedstock and renewable energy helps alleviate 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.
