Development of methodologies for complete utilization of poultry abattoir waste

Abstract

The growing number of poultry abattoir is generating a large amount of waste daily. The improper method adopted by abattoir owners for their disposal is causing the danger of many environmental. This paper based on study conducted about various methods that are available for utilisation of waste from poultry abattoir and survey conducted among local abattoir owners suggests method for utilization of wastes that can be adopted by small scale industries. Wastes were classified as offal, feather and feet based on their properties and existing uses. Method for experiments conducted for finding effects of various co-composting materials and different enhancers and effect of use of mixer on softness of feather is presented in this paper. The inference from the result obtained from experiments was that, offal could be composted to make organic manure with the addition of coir pith, saw dust, paddy straw etc., out of which coir pith was most effective and the least degradable feather could be utilised for long life resilient filling material for cushion/bed/pillows etc. after processing, for which a simple mixer-grinder with suitable blade could be utilised.
