ABSTRACT:
A process is described for producing an animal feed, comparable to feathermeal in properties and appearance, from two waste products: float sludge and activated sludge. The process uses a bulking agent for extracting excess fat from the sludges, particularly the float sludge, while a mixture of the sludges and the bulking agent is being stirred, heated, and dried. Blood, chicken litter, meat scrap, and the like can be substituted for activated sludge to provide protein. The bulking agent can be any material that can expose the sludges to air, that is capable of absorbing fat, and that can be separated from the dried and partially de-fatted sludges. Wood chips are the preferred bulking agent. Wood shavings, shredded cardboard, shredded newspaper, paunch manure, and the like can be substituted for wood chips as the bulking agent. More specifically, the process comprises: (a) admixing wood chips, float sludge, and activated sludge to form a mixture; (b) heating and tumbling the mixture until it is substantially dry; and (c) screening the dried mixture to produce a meal as the product and fat-impregnated wood chips as a bay-product. The meal is of high quality, having a fat content of less than 15% and a protein content of at least 40%.
