Abstract: An improved lubricant for use with a conveyor in a meat packing plant meeting the requirements of (1) adequate lubricity, (2) "drip-resistance," (3) safety, i.e., approval of the composition and its ingredients by the U.S.D.A., (4) rust resistance, (5) economy of manufacture and use and (6) the ability to be removed by cleaning methods is provided by preparing a mixture of mineral oil, a fatty acid and a polybutene, each being acceptable for incidental contact with food, in certain minimum amounts and increasing the amounts of one or more of said components such that the improved lubricant has a viscosity of 20-160 centipoise. A method of improving a lubricant for use on a conveyor in a meat packing plant and a method of lubricating the conveyor are also disclosed.

Abstract: Waste water from fat rendering and meat processing plants is treated in a conventional clarifier to produce better separation of suspended solids and fat from waste water by the addition of a first solution of pH controlling agent in combination with a surfactant and a second solution of a flocculating agent into the waste water streams entering the clarifier.

Abstract: A process for facilitating the separation of fat from a waste stream composition comprising water, fat, fatty acids and solids produced in food processing plants and animal rendering plants. In one embodiment, an alkaline pH control composition and an aluminum salt flocculant composition are added to the waste stream composition for subsequent separation in a clarifier of the waste stream composition into an essentially fatty layer, an essentially water layer, and an essentially solids layer. In a second embodiment, a conventional dissolved air flotation system is employed. An acidified aluminum salt flocculant composition is added to the waste stream composition prior to dissolved air introduction. The resulting waste stream composition subsequently separates in a clarifier into the three layers described above.
