Suann Guthrie, Senior Vice President of Investor Relations, Sustainability & Global Communications at Darling Ingredients, has appeared on NYSE television programs in 2024 and 2025 to discuss the company’s business activities and strategy. In June 2025, she announced Darling Ingredients’ dual listing on the NYSE Texas exchange, stating the company would continue to trade under the ticker symbol DR on both exchanges. She described the move as providing greater exposure and flexibility, and noted that Darling Ingredients, which moved its headquarters to Dallas in 1986, wanted to be part of the NYSE’s relocation of its Chicago trading floor to Texas. Guthrie also discussed a joint venture with a company called Toenderloo to combine their collagen and gelatin businesses, which she said would create a $1.5 billion revenue company focused on the collagen-based health, wellness, and nutrition sector. In earlier appearances, Guthrie described Darling Ingredients as a company that recycles discards from the animal agriculture and food waste industries into ingredients for pet food, livestock feed, and human consumption, as well as feedstock for renewable diesel and sustainable aviation fuel. She stated that the company is a vertically integrated producer of renewable diesel through a 50-50 joint venture and that it shipped its first load of sustainable aviation fuel in the United States. Guthrie also outlined sustainability initiatives, including joining the Science Based Targets initiative (SBTi) to set emissions reduction goals, conducting a biodiversity risk assessment for U.S. facilities, and working to calculate a carbon avoidance number. She mentioned research and development on a proprietary enzymatic process to separate amino acid chains from collagen for health benefits, including a product intended to slow glucose absorption.
“We are redefining the waste mindset. What we do is we take discards from the animal agriculture and food waste industries and we turn those into hundreds of valuable ingredients.”
“Today we're also using those ingredients as feedstock to decarbonize the world in the form of renewable diesel and sustainable aviation fuel.”
“We just announced a joint venture with another company called Toenderloo. We're combining our collagen and gelatin companies and we're creating a $1.5 billion revenue company to help accelerate and grow the collagen-based health, wellness, and nutrition sector.”
“We're so excited to be dual listed on NYSE Texas as well as the regular listing on NYSE New York. It gives us a lot more exposure, puts us on the map in more locations, and gives us greater flexibility.”
“Texas is one of the most booming economies in the world right now and we're so excited to have NYSE as part of that.”
“We look at how can we get the highest and greatest value for the end products of what we take from the animal waste industries.

“We are one of the largest renewable diesel and sustainable aviation fuels producers, making that from animal fats and used cooking oil.”
“Our CEO at the time was looking for a way to decouple us from corn prices because all animal fat had a use for in the world was basically added calories to fatten up an animal for slaughter. He found an opportunity, a piece of technology that was able to take waste fat, animal fat, and used cooking oil and create a tru...”
“Sustainable aviation fuel is number one. We just shipped our first load of sustainable aviation fuel that'll be going to a market here in the United States, an amazing opportunity to help decarbonize the aviation sector because today there is no other decarbonization option.”
“Through a proprietary enzymatic process, we separate amino acid chains from gelatin collagen, and those amino acid chains have known health benefits. The first product we launched is a natural collagen product that helps slow the absorption of glucose into your bloodstream.”
“Sustainable aviation fuel is going to continue to grow within our space, and we are already working on research and development on that activated peptide to be able to attack other health concerns like skin health, gut health, and memory retention.”
“At Darling Ingredients we believe that every end has a new beginning. We take and recycle discards from the animal agriculture and food industries and create hundreds of valuable products that go back into society in the form of pet food ingredients, animal agriculture food ingredients, and people food ingredients like...”
“We are one of the world's largest providers of renewable diesel made out of animal fat and used cooking oil through a 50-50 joint venture.”
