Waste Management in Poultry

Pashu Sandesh, 13 Feb 2020

ICAR-Central Avian Research Institute (CARI), Izatnagar, Bareilly has developed two pilot-scale technologies for waste management and adoption of new renewable energy:

  • Dilution, Acidification and Carbonization (DAC) technology used for all-weather biogas generation exclusively from poultry excreta and further utilization of it is used as manure in agriculture. The signifying point of this technology is that only poultry excreta are required for biogas production. Used slurry has good manure value and germination potential (>90%), hence can be easily applied in agricultural fields without burning effect on plants which is a common problem with crude poultry excreta. The overall impact of this technology is to alleviate environmental pollution, economize poultry production and generate additional income at poultry establishments.
  • Aerobic composting of poultry wastes (litter, excreta, hatchery waste, slaughter waste, mortalities etc.) has been standardized using various poultry wastes and carbonaceous material (tree leaves, grasses and other plant wastes) for conversion into manure for utilization in organic crop farming as an alternative to chemical fertilizers.
  • These two technologies reduce pollutants, bad odour and flies from poultry establishments. ln addition, preparation of vermicompost from poultry litter waste (cage litter) is also being practised at ICAR institutes.
