Rendering is a process that converts waste animal tissue into
stable, value-added materials. Rendering can refer to any
processing of animal products into more useful materials, or, more
narrowly, to the rendering of whole animal fatty tissue into
purified fats like lard or tallow. Rendering can be carried out on
an industrial, farm, or kitchen scale.
The majority of tissue processed comes from slaughterhouses, but
also includes restaurant grease and butcher shop trimmings and
expired meat from grocery stores. This material can include the
fatty tissue, bones, and offal, as well as entire carcasses of
animals condemned at slaughterhouses, and those that have died on
farms, in transit, etc. The most common animal sources are beef,
pork, sheep, and poultry.
The rendering process simultaneously dries the material and
separates the fat from the bone and protein. A rendering process
yields a fat commodity (yellow grease, choice white grease,
bleachable fancy tallow, etc.) and a protein meal (meat and bone
meal, poultry byproduct meal, etc.).
Rendering plants often also handle other materials, such as
slaughterhouse blood, feathers and hair, but do so using processes
distinct from true rendering.
