The consolidation of two leading rendering companies is completed, as Darling International has taken over ownership of Rothsay. Darling International purchased the rendering and biodiesel business from Maple Leaf Foods for a price of about $645 million.

Rothsay is the leading rendering company in Canada and a leading producer of biodiesel. The business operates six rendering plants located in Manitoba, Ontario, Quebec and Nova Scotia, and a biodiesel facility in Quebec. It employs approximately 550 people.

Darling International Inc. is the largest and only publicly traded provider of rendering and bakery residuals recycling solutions to the U.S. food industry. It is based in Irving, Texas.

Maple Leaf Foods Inc. is a leading food company headquartered in Toronto, Canada. Proceeds from the transaction will initially be used to pay down Maple Leaf Foods' debt.
