Darling Ingredients Inc. operates through three primary business segments: Feed Ingredients, Food Ingredients, and Fuel Ingredients. The Feed Ingredients segment, which generates the majority of the company's revenue, processes animal by-products and used cooking oils into fats, protein meals, and other ingredients for animal nutrition and pet food. The Food Ingredients segment produces collagen, gelatin, and natural casings for the food and pharmaceutical industries. The Fuel Ingredients segment converts organic waste and animal fats into renewable energy, notably through its Diamond Green Diesel joint venture, which is a major producer of renewable diesel. Headquartered in Texas, the company operates over 260 facilities globally, positioning itself as a critical link between agricultural waste streams and the production of sustainable ingredients and biofuels.
