At a beef slaughtering plant, the kill capacity can be 250 animals per hour. In a ten-hour day this represents a tremendous quantity of blood, paunch, and manure, which must be disposed of in such a way so as not to further tax the waste-carrying capacity of the nearby rivers or to increase the ever growing problem of pollution of air, land, and water. Thus it was decided to test facilities for the drying of the whole blood and the paunch contents of rumen generated in the slaughtering operation. The manure would be disposed of directly for agricultural fertilizer. The project demonstrates the economic and technical feasibility of completely separating the blood and rumen generated in the slaughter operation, and drying of these materials with a view toward the sale of the dehydrated products as animal feeds or for feed additives.

Agricultural Waste Management: Problems, Processes, and Approaches is a summary of the processes and approaches applicable to the solution of agricultural waste management problems. This book is organized into three part encompassing 13 chapters that is intended as a bridge between theory and practice as well as between the many disciplines that are involved in agricultural waste management. The primary focus of agricultural waste management is on the obvious problems of odor control and feedlot runoff. The first part looks into the status of agricultural waste problem and the application of engineering and scientific fundamentals to the management of these wastes. This part also deals with the role of the land in waste management, and then outlines the guidelines for the development of feasible waste management systems. The second part describes the fundamentals, principles, and benefits of various waste management processes, including biological processes, ponds and lagoons, aerobic, anaerobic, physical, and chemical treatments, and nitrogen control; as well as treatment systems, such as ponds, lagoons, and land disposal. The third part examines the integration of the most economical and equitable combination of alternative technologies into feasible waste management approaches. This work will be of great value to agricultural producers and manufacturers, scientists, and engineers.
