Animal Wastes—A National Problem

A state of the art summary is given of the control and management of animal wastes. Items considered include the magnitude of the problem, pollution that has been caused by animal wastes, feasible treatment processes, major problem areas, and areas for future activity. The problems currently associated with the handling, treatment, and disposal of animal wastes will be magnified in the future. Ultimate disposal techniques for untreated animal solids and liquids as well as the residues from waste treatment processes should be integrated with feasible handling and treatment processes to develop suitable waste control and abatement systems. Large-scale animal production facilities should be considered as individual industries responsible for pollution abatement.
