Sustainability in Biofuel & Biodiesel Production

Your fats and used cooking oils can be tomorrow’s resources

At DAR PRO Solutions, we don’t just manage your used oil, fats and trap materials – we repurpose them, creating valuable new resources that contribute to a more sustainable world. We process the organic meat by-products we collect from supermarkets and retailers, and the used cooking oil we collect from restaurants, into biodiesel and renewable diesel, as well as nutritional ingredients for livestock feed and pet food.  Our processed oils, fats and fatty acids can also be used in a variety of consumer products found in homes across the world, as well as for industrial and commercial use.

Our innovative portfolio of products, and their varied applications used across a diverse range of industries, has helped us lead our industry's growth and development, as well as assisted our customers around the world work towards their own sustainability goals. 

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 was the first company in our industry to pioneer the commercial production of biodiesel utilizing recycled animal fats and used cooking oils in the 1990s. Our U.S. biodiesel plant, still in operation in Butler, Kentucky, produces clean, efficient fuel that a meets all ASTM 6751 specifications, and reduced emissions by 80% as compared to petroleum diesel.  We were also the first in Canada to operate a commercial animal fat/used cooking oil biodiesel facility, located outside Montreal. Started in 2005, our Canadian Rothsay brand produces approximately 45 liters of biodiesel per year.

In 2013, with our partner Valero Energy Corp., we began operations at the newly constructed Diamond Green Diesel facility outside of New Orleans. This facility is the largest 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 emits up to 85% less greenhouse gases.  This clean, efficient renewable diesel can be dropped into the existing pipeline for distribution to diesel retailers. DGD currently produces 160 million gallons of renewable diesel annually, and has announced plans to expand to 275 million gallons by second quarter of 2018.

As energy resources decline and demand rises, the opportunity to use our used cooking oils and animal fats as feedstock for renewable energy has become more urgent – and more desirable – than ever. No other company in the world has done as much to elevate the value of our customers’ used cooking oil and animal fats.

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

  • We divert carbon- and nitrogen-rich materials away from the soil, surface waters, ground water 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 mortalities.
