Back in August, we told you about Darling International Inc.’s bid to buy Canada-based Rothsay, the rendering and biodiesel division of Maple Leaf Foods Inc. Darling is now expected to close that deal to give the company animal fats for biodiesel feedstock on October 28, 2013.

Rothsay is the leading recycler of animal by-products in Canada and provides an essential service for the efficient and environmentally responsible collecting, processing and recapturing of edible and inedible by-products. Rothsay processes raw materials into finished products of fats and proteins. Rothsay has a network of five rendering plants in Manitoba, Ontario and Nova Scotia and a biodiesel operation in Quebec, Canada. Rothsay employs approximately 550 people, who will transition to Darling once the transaction closes.

Darling International Inc. is the largest and only publicly traded provider of rendering and bakery residuals recycling solutions to the nation’s food industry. The Company recycles beef, poultry and pork by-product streams into useable ingredients such as tallow, feed-grade fats, meat and bone meal, poultry meal and hides. The Company also recovers and converts used cooking oil and commercial bakery residuals into valuable feed and fuel ingredients. These products are primarily sold to agricultural, pet food, leather, oleo-chemical and biodiesel manufacturers around the world. In addition, the Company provides grease trap collection services and sells used cooking oil collection equipment to restaurants.

Earlier this year, Texas-based Darling opened a joint venture renewable diesel plant with energy giant Valero in Louisiana. That plant also uses animal fat to make the renewable diesel, as well as using waste cooking oil and corn oil.
