Rothsay, a division of Darling International Canada Inc. is the largest rendering operation in Canada, with six processing facilities. The rendering process recycles animal and poultry by-products, including bones, trim, fat, offal and feathers, into a broad range of commercial tallow and protein products.
At the same time that we are taking care of inedible co-products, we’re also busy taking care of the environment. Our stringent processing operations are the safest and most efficient method of handling these organic materials, leaving less of a footprint on the environment than disposal methods such as using landfills or composting. To us, sustainability is not a goal to strive to accomplish – it lies at the foundation of what we do each day.
