Poultry Litter Biochar: An Approach towards Poultry Litter Management – A Review

Abstract

Poultry litter is an abundantly available waste biomass, which is used for direct land applications since a long time. Direct use of poultry litter on agricultural lands causes many environmental concerns like, nutrient runoff, eutrop hication, flaw odor, greenhouse gas emission due to decaying and microbial contamination. To reduce the environmental concerns, thermochemical conversion of poultry litter into biochar can be an economically sustainable approach. Poultry litter converted i nto biochar with pyrolysis process also produces additional value products, syngas and bio - oil. Use of poultry litter biochar can improve the soil fertility, water holding capacity and nutrient retention power. Poultry litter biochar also has capacity for remediation of organic and inorganic contaminants from soil and water.
