Residuals to resources

Transforming edible and inedible residual bionutrients into valued resources is what we do. From Darling Ingredients’ beginnings, decades before sustainability became a household term or corporate directive, our pioneering spirit imagined and developed innovative ways to transform inedible co-products into sustainable ingredients. Both economic and ecological sustainability are part of our core business. We believe sustainability is more than what we produce – it’s the foundation of how we conduct our business and serve as stewards of our environment.

Eco-friendly solutions for a growing world

Our company believes the solutions we deliver are part of a broader shift occurring around the world. A shift that involves a change of perspective regarding our attitude towards the earth’s resources. Whether we’re developing nourishing ingredients to keep our pets healthy or producing renewable fuel from industrial residuals, our constant aim is to generate new resources, rather than depleting existing ones. 

Compliance as a matter of conviction

As part of Darling Ingredients, we at Rothsay take responsibility in everything we do – for our business, our people, our planet. We comply with all applicable environmental, health and safety laws and regulations – not as a matter of duty, but because of what we believe. We strive to continually improve our compliance, services, products and business practices; prevent pollution at the source; and integrate environmental, health and safety protocols throughout our operations.

We live our core values of entrepreneurship, integrity and transparency by committing ourselves to ethical and honest conduct in all matters.
