Process Variations
The rendering process varies from plant to plant in many ways.
- Whether the end products are to be used as human food is based on the type of raw material and the processing methods.
- Whether the end products are to be used as animal or pet food.
- The material may be processed wet or dry. In wet processing, either boiling water or steam is added to the material, causing fat to rise to the surface; in dry processing, fat is released by dehydrating the raw material.
- The temperature range used, whether high or low.
- Processing may be either in discrete batches or in a continuous process.
- The processing plant may be operated by an independent company that collects the material on the open market, or by the packing plant that produced the material.

Famous quotes containing the words process and/or variations:
“Thinking is seeing.... Every human science is based on deduction, which is a slow process of seeing by which we work up from the effect to the cause; or, in a wider sense, all poetry like every work of art proceeds from a swift vision of things.”
—Honoré De Balzac (1799–1850)
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
