Poultry Byproducts

The poultry industry creates animal waste from excreta/manure together with waste from poultry and egg processing. These represent a series of environmental problems together with a loss from no producing potential co-products instead of waste products. The topics covered attempt to reveal some of the possibilities available for non-food uses of poultry waste, while at the same time reducing the acute environmental problems. This chapter presents methods for treating and storing poultry waste: stacking method (depot), drying of manure, and ensiling chicken manure. There is scope to use poultry waste to produce value-added products such as fertilizer, biodiesel, animal feed, electricity, biogas, bone powder, and biodegradable plastics. Poultry bones, skin and, feet can be processed to poultry and/or bone meal or can considered as poultry waste. Poultry feet (duck and chicken) are another potential source of gelatin production from poultry waste.
