Darling Ingredients ‘Can Do’ Chief Strategist To Retire, Embraces New Chapter with Named Successor

As John Bullock, known for his transformational leadership, plans to retire from Darling Ingredients, the company welcomes Robert Day, a veteran with nearly three decades of agribusiness experience, to continue Bullock's legacy of innovation and strategic growth.

Irving-based Darling Ingredients Inc. announced that Chief Strategy Officer John Bullock will retire effective Feb. 15, 2024, and that Robert Day has been named to succeed him.

The company said that Bullock joined Darling Ingredients in 2012 and has been instrumental in transforming it into a world leader in upcycling animal byproducts to their highest value through the creation of new markets.

“John is the guy who — if someone said you can’t do that — went and did it and figured out how to make money at it,” Chairman and CEO Randall C. Stuewe said in a statement. “John helped me and the board of directors see the tremendous value we can unlock by focusing on the end ingredient we produce, not how we process the raw material. Throughout John’s tenure, Darling has entered new markets, created new products and grown tremendously. His leadership has laid a strong foundation for this company’s continued success through innovation and strategy.”

The company said that under Bullock’s leadership, Darling Ingredients entered the renewable diesel market in 2013 to maximize value for its waste fats.

Since then, through its 50/50 joint venture, Diamond Green Diesel, Darling has evolved into one of the largest renewable diesel providers in the world and soon will be one of the largest sustainable aviation fuel producers in the world.

Bullock began his career in 1978 at General Mills, focusing on ingredient purchasing and risk management. He then went to ConAgra Foods in 1991, where he led the mergers and acquisitions group for ConAgra’s Trading and Processing companies. After ConAngra, Bullock operated a boutique consulting firm focused on agricultural business expansions.

‘A wealth of agribusiness experience’

Day will join Darling Ingredients as chief strategy officer, effective Aug. 6. He brings nearly 30 years of experience in agriculture, soft, and energy commodities.

Darling Ingredients has named Robert Day Chief Strategy Officer.

Most recently, Day was a partner at Ascendant Partners, a boutique investment bank focusing on the food, agriculture, and renewable fuels industries. Before that, Day was CEO at Ceres Global Ag Corp., managing director Asia at ED&F Man, and he held a variety of senior management and commercial roles, including more than 19 years with Cargill in Asia, Latin America, and the U.S.

“We’re excited to have Bob join our executive team,” Stuewe said. “Bob brings a wealth of agribusiness experience and an impressive track record of developing transforming businesses.”

Darling Ingredients Inc. is the largest publicly traded company turning edible by-products and food waste into sustainable products and a leading producer of renewable energy.
