Waste Valorization Technologies for Egg and Broiler Industries

The poultry industry is one of the fastest-growing markets at the global level. As the industry expands, the solid waste generated from the poultry sector increases. However, a large amount of waste are generated in poultry farms which needs proper management and disposal to avoid many serious issues like environmental pollution, the spread of diseases due to pathogens residing in the waste as well as breeding of flies and rodents near the waste. Several methods are implemented for the proper utilization and disposal of residues produced in the farms. The methodology used for management varies widely based on many factors like the type of waste generated, nutritional value, and potential hazards to humans and the environment. The techniques adapted for utilization or disposal of the waste generated have evolved from simple conventional methods to highly advanced and more reliable methods (Pyrolysis, anaerobic digestion and catalytic pyrolysis), which are practiced increasingly nowadays, especially in large-scale poultry farms. Many projects and research are being held to improvise waste management techniques in the coming years. The appropriate processing, utilization and disposal of waste and its by-products are important to prevent unwanted side effects and increase the pecuniary output.
