What does Darling Ingredients do?

Darling Ingredients Inc. is the international leader in converting edible and inedible bio-nutrients from animal origin into nutritional, safe and sustainable food, feed and fuel ingredients for a growing, global population. Darling has over 200 processing plants on five continents with sales and distribution offices throughout the world, and is the only publicly traded company in our industry (NYSE/DAR). They are headquartered in Irving, Texas with approximately 10,000 worldwide, dedicated employees providing services and products to an international market.

What demand do our rendering operations have on water resources?

Water is the most critical limiting resource throughout the world. The food processing byproducts we convert into value added ingredients contains a significant amount of water. The majority of our conversion processes recover this water for reuse and/or a return to the environment following varied levels of treatment. The net result is Darling produces more water than it uses.

If Darling is international, does Rothsay operate all around the world?

Rothsay offers used cooking oil, grease trap, and fat and bone services to the Canadian foodservice industry. Their sister brand, DAR PRO Solutions, offers the same services in the U.S. Restaurant services are not, at this time, available from Darling Ingredients in the rest of the world, though there are some fat and bone pickup services from retailers in some European countries under our Rendac brand. Some of the products Rothsay produces, from biodiesel to premium fat and protein feed ingredients, are marketed outside of Canada.
