Rendering is Recycling

Recycling in its truest form, the rendering process transforms inedible animal by-products, such as meat scraps, fat and bone into valuable, nutrient rich finished goods. Rendering is a necessary service for the agriculture and food industries and plays an important role in ensuring that animal by-products are disposed of safely.

Rothsay recycles more than 99% of its inputs into value-added products

  • Inedible animal by-products received from abattoirs, food processing plants, supermarkets, and restaurants are processed at our facility into valuable commodities.
  • Recycling animal by-products contributes to the preservation of our environment by providing a safe disposal alternative to landfills and incineration for these materials.
  • Not only does the recycling process not consume water, it produces water which is then sent through a sophisticated and rigorous wastewater treatment and purification system prior to discharge into the natural local watershed.
  • Odour causing compounds in the air are destroyed by scrubbers and sophisticated biofilters.

Our company's goal is to be a leader in environmental management.
