In India poultry industry is growing rapidly and contributes towards improving the standard of living of people through poverty alleviation and creating employment opportunities. The problem coming along with the growth in poultry production is the poultry waste that needs to be taken care of, as a non-appropriate treatment or disposal can become risky for environment and humans. For instance, different kind of poultry wastes can contribute in the spread of diseases and may pollute soil and groundwater resources if not properly handled. Poultry Waste can be defined as anything that is no longer useful and needs to be disposed off properly. The solid poultry waste consists of feathers, hatchery waste (empty shells, infertile eggs, dead embryos etc), shells, sludge, abattoir waste like offal, blood, feathers and condemned carcasses and mortality.
The disposal of poultry waste presents significant environmental, biological, and financial problems for the poultry industry. There are several ways of disposing of poultry waste including burial, rendering, incineration, compositing, feed for livestock, fertilizer or source of energy. Each disposal option has its own advantages and disadvantages. Direct disposal of poultry waste, mortality and abattoir condemnations at the landfills, application on farm lands as a fertilizer, burning and compositing are the most commonly practiced methods of poultry waste disposal used in India. These methods are challenged by environmental pollution Boards in India and it will not be easy to use these traditional method of disposing off of poultry waste and poultry producers will have to adopt scientific method of disposing off of poultry waste to convert poultry waste in to wealth.
Rendering is one of the scientific option which can convert poultry waste in to wealth. Here we will discuss Rendering:
Rendering is a process of using high temperature and pressure to convert whole animal and poultry carcasses or their by-products with little or no value to a safe, nutritionally and economically valuable feed ingredient. It combines blending, cooking, pressurizing, fat melting, water evaporation, and microbial inactivation. Rendering process cooks the product while killing pathogenic agents and converting the product into a value-added product which can be used as pet feed ingredients or livestock feed ingredients. Although rendering is an effective method, only few poultry operations use it probably due to misconceived reason of its high operational costs.
In present conditions where environmental and pollution issues are addressed strictly by government authorities, Poultry Waste Rendering Plants are an indispensable part of poultry operations. Poultry Waste Rendering plants also perform one of the most complementing functions for modern slaughter houses.
Rendering facility also produces a variety of by- products by further processing and development. Rendering is also the process to convert dead chicken, chicken waste, feathers, tissues, market waste in to valuable material like feather meal,chicken meal and animal fat which are very rich in protein.
