Over a Century of Corporate Expertise
Rothsay Biodiesel is proud to be part of the Darling Ingredients family, the world’s largest publicly-traded (NYSE/DAR) producer of sustainable natural ingredients from edible and inedible bio-nutrients, headquartered in Dallas, Texas with operations spanning five continents. Darling Ingredients is committed to continued growth and developing sustainable solutions through all its premium brands.
Rothsay Biodiesel has a dependable supply of raw materials, using the tallow and yellow grease that is produced at our rendering facilities. Rothsay is Canada's largest rendering operation, and having access to this secured source of material enables consistent, ratable production that in turn ensures on-time fulfillment of customer orders.
Our control over raw materials ensures consistent inputs which allow us to reliably and consistently produce the highest quality product.
Before biodiesel orders are shipped, the product is tested both internally and externally to ensure the product meets or surpasses all industry standards.
The Ste-Catherine, Quebec facility is equipped to ship product by totes, tanker trucks and railcars. Railcars can be arranged for customers without their own fleet.
Rothsay Biodiesel is committed to having the best possible team to meet the needs and expectations of our customers. We are committed to building long-term business relationships through a focus on customer service from the point of first contact to the delivery and use of our product.
