Rendering

Rendering refers to the processing of grease, fat, meat, or bone into usable products. Rendering companies process animal by-products into saleable commodities. Collection service areas, costs, and types of materials accepted vary. Grease from restaurants is a common by-product collected and processed by rendering or tallow companies, but many companies will also collect or accept meat, fat, bone, and dead animal carcasses.

If you have excess oil, grease, uncooked meat, bone, or animal blood, contact a local renderer for collection. These companies collect and process the materials into feedstock for a variety of products. Please contact rendering companies directly to arrange for service. Rendering companies are listed in the Yellow Pages under "rendering" or "grease collection."
