Poultry Waste Valorization and its Applications in Various Fields
Chapter 7
Keywords:
Poultry waste, Bio manure, Pesticides, Biofuels and BiomaterialsAbstract
Poultry farming has witnessed substantial growth in recent decades due to the global demand for poultry products. This growth, however, has led to a pressing concern – the management of poultry waste. The intensive nature of modern poultry production systems has resulted in the generation of significant amounts of waste, posing environmental and public health challenges. Poultry waste consists of a diverse range of materials, including manure, feathers, bedding materials, and mortalities. Understanding its complex composition is crucial for effective waste management strategies. One promising avenue for valorising poultry waste is through circular economy approaches. Chicken bones, for instance, can be processed to recover valuable nutrients like phosphorus and calcium. Hydrothermal treatment has been identified as an efficient process to extract valuable byproducts from chicken bones, such as hydro-char and process water, which can be utilized for various purposes. This review focuses on poultry waste valorisation and their applications in various fields including agriculture, textile industry, aquaculture, food processing.
