Scope of Poultry Waste Utilization

Abstract

Poultry farming wastes containing excreta, bedding material, waste feed, dead birds, broken eggs, feathers and offal could emerge into major environmental pollutants. Proven technology and disposal methods are necessary to mitigate their threat on the environment. The major wastes like poultry feathers, offal and litter have different field applications. Poultry feathers being rich sources of keratin proteins and amino acids, can be converted into valuable products such as feather meal, bio diesel, biodegradable plastic and fertilizer. Poultry offal contains certain nutrients and can be used as a dried poultry manure and fertilizer or as an organic raw material for methane production. The remaining waste could be disposed off possibly by incineration or by burial and controlled landfills. Poultry manure is also useful as fertilizer, methane and to produce electricity. This review discusses in detail about the scope for utilization of various poultry wastes. Poultry waste generation is enormous. However, cost effective technologies are yet to be identified to recycle the waste to useful products.
