Analysis of modern approaches to the processing of poultry waste and by-products: prospects for use in industrial sectors

Abstract

Poultry processing is characterized by the accumulation of significant volumes of industrial waste (manure, waste from the incubation and slaughter of poultry, feathers, and carcasses). The overall purpose of this review is to analyze the current global practice of recycling poultry waste and by-products and to study the technological prospects for modifying their properties in terms of obtaining value-added products and preventing environmental pollution. Processing agricultural raw materials in a waste-free production cycle is based on certain economic and ecological aspects. The variety of morphological structures and chemical compositions of by-products and waste allows to obtain valuable components using a wide range of modern processing technologies. The use of recycled waste and by-products of poultry processing varies widely: from applications in food technologies to the production of biofuels. Many researchers strive to develop efficient technologies for converting secondary poultry products; a great deal of attention is paid to enzyme-based technologies, which have been improved significantly.
