Environmental Pollution and Waste Management
 
Description Poultry litter is being generated in huge amounts from small-scale as well as medium poultry industries all around the world. It is a potential soil fertilizer however its unscientific and improper management practices lead to a lot of environmental problems. The mass generation of poultry litter with excess moisture became a burden to farm holder for its sustainable disposal. This study deals with, biochar preparation and characterization of broiler’s poultry litter to identify its potentialities. The litter was pyrolyzed at five different temperatures 200oC, 300oC, 400oC, 500oC, and 600oC with 60 minutes residence time. Both the proximate and ultimate analysis of poultry litter biochar (PLB) was performed. Certain proximate parameters were correlated (Pearson correlation coefficient) positively (ash content and fixed C) or negatively (yield and volatile matter %) with the pyrolysis temperature. The pH and EC values were increased in PLB samples, whereas the elemental compositions such as H%, N%, and S% were decreased. In comparison with raw poultry litter, the percentage carbon (C %) was found to be high in all biochar samples. The SEM analysis has shown that, macropores were abundant in poultry litter biochar prepared at temperature ranges between 200 oC to 600 oC, whereas the micropores and mesopores were absent in feedstock and biochar particles. From the EDAX spectrum, it was found that the atomic (%) compositions were high in PLB compared to raw poultry litter. It was observed that, 200oC with 60 minutes residence time was the optimum temperature for poultry litter biochar preparation in terms of yield. From this study it was declare that, conversion of raw poultry litter to biochar could be a best waste management practice and poultry litter biochar might be a potential organic supplement for sustainable agriculture and a favorable adsorbent in soil remediation applications. Keywords: Poultry litter, waste management, biochar, pyrolysis, characterization, soil remediation.
