New markets for tallow through research

It is postulated that expanded markets and a more stable price structure for rendered animal fats can be attained through research to develop new products and new uses for these commodities. An industry-supported research program to accomplish this must be designed to develop high volume, low cost products with a reasonable chance to fulfill a market need. Thus the technical research must be accompanied by, and integrated with, market research and careful estimates of production costs. The Fats and Proteins Research Foundation has used these guidelines in the research that it has supported for the past eight years. The following new uses and new products from inedible animal fats have been developed: (1) an air-entraining agent for concrete; (2) a water repellent coating for concrete; (3) a fat-containing admixture for concrete; and (4) a fat-coated urea for ruminant feeds. The estimated market potential for tallow and other animal fats for these new products is 200–400 million pounds annually in the United States by 1980.
