WASTE SAVING BY IMPROVEMENTS IN MILK PLANT EQUIPMENT .' ;-fF-i?-';^' ' Dr. H. A. Trebler '¦'¦¦'; J, Chemical Engineer, Sealtest, Inc. Baltimore, Md. ; :.->r.V; The wastes in the dairy industry may be classified as follows: 1. Wastes of spoiled products. These occur especially in the summer time and are mostly due to insufficient cooling facilities on the farms or insufficient plant capacity to handle the incom¬ ing milk before it sours. 2. Wastes of by-products such as whey, buttermilk or excess skim milk. These are due mostly to the fact that many plants are not yet fully equipped to utilize these valuable materials and the farmers are not always in a position to take them back to the farm for stock feed. Anyway during the period of maximum milk production the farmers may have a minimum of young stock to feed. 3. Wastes due to poorly designed or poorly maintained equipment and due to negligence or poorly trained i>ersonnel. 4. Unavoidable wastes in rinsings and wash waters from equipment.
