Sustainable Up-Gradation of Poultry Litter into A Valuable Product

Poultry industry is one of the fast growing in the developing countries like India and South East Asian countries. This industry is producing a huge amount of solid waste in the form poultry litter which is directly fed into the agricultural or barren lands located near the poultry farms. This could pose an environmental threat as the poultry litter contains massive amounts of ammonia and coli form bacteria. So the present investigation is designed to upgrade the poultry litter into a valuable product with the help of earthworm species. Here, we pre-treated the poultry litter in a tank as it contains more amount of ammonia and other toxic chemicals. For the present investigation we used three earthworm species Eudrillus eugineae, Eisenia fetida and Lampito mauritii for bioconversion. After treatment with earthworm species the physico-chemical parameters namely pH, Electrical conductivity, Total organic carbon ratio, Carbon: Nitrogen ratio, Total calcium, magnesium and nitrogen ratio of the poultry litters were measured. From the results it was inferred that the poultry litter treated with Eudrillus eugineae found to have significant composting activities.
