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.
