Sustainable Waste Solutions

Serving the food industry with sustainable waste solutions since 1882

For over a century, our company has provided increasingly diverse and sustainable waste solutions to the U.S. food industry for the removal and repurposing of organic meat by-products and used cooking oils. The history of DAR PRO Solutions and its sister brands, DAR PRO Ingredients and DAR PRO Bioenergy, reaches as far back as 1882 with the founding of Ira C. Darling & Company, which later evolved into today’s Darling Ingredients. In 2012, Darling Ingredients acquired Griffin Industries LLC, another experienced and leading player in the American rendering industry. Shortly after, the DAR PRO Solutions brand was launched to bring together Darling and Griffin’s rendering and restaurant services and their feed and fuel products under a single brand, providing a uniform service provider for customers all over the US. In 2015, we recognized that we could more directly provide for the needs of our customers by splitting DAR PRO into three distinct brands that work closely together to create maximum synergy: DAR PRO Ingredients, which builds on over a century of expertise and innovation by providing quality proteins and fats to pet food, feed and aqua feed markets; DAR PRO Bioenergy, which brings together our pioneering efforts in renewable fuels; and the continuation of DAR PRO Solutions as North America’s leading provider of used cooking oil collection and grease trap services for restaurants and supermarkets.
