Quick Summary

Brown grease is a type of lubricant derived from inedible animal fats, specifically a mixture of beef, mutton, and hog fats. It is one of several types of animal-based greases, which also include yellow grease (from hog parts) and white grease (from hog fat unfit for consumption). These greases are produced by rendering waste animal parts, condemned animals, or refuse fat. In some industrial settings, food offal, butcher-shop scraps, and garbage are also used to recover fats for grease production. Greases can also be made from petroleum-derived or synthetic oils thickened with agents like soap or inorganic gels.123
