Purpose This research aimed to study the adsorption of ammonium and nitrate by simply modifying the surface of the rice husk using slow pyrolysis and surfactants modifcation. Methods Rice husk biochar was prepared by slowly pyrolyzing at 500 °C, 2 h. The rice husk and its biochar were modifed by cetyltrimethylammonium bromide or sodium dodecylbenzenesulfonate. FTIR, BET […]
Purpose Crop wastes are underused organic resources due to low heating value and slow decomposition rates. However, conversion to biochar through pyrolysis could offer agronomic and environmental benefits. The study compared the pyrolysis of biochar from crop wastes, assessed their physicochemical properties for the purposeful use to improve soil fertility, crop productivity and their carbon […]
Purpose The role of cocoa pod husk waste in soil cadmium contamination has been largely overlooked. Hence, this study aims to provide a strategy for the management of cocoa pod husk waste when representing a pollution menace for cocoa plantations. Method Cocoa pod husks waste was subjected to composting and pyrolysis for decreasing the heavy […]
Purpose: Poor management of chicken litter by the poultry industry has caused many environmental issues. Biochar’s unique characteristics make poultry litter-to-biochar conversion an intriguing management option thus, could be utilized as an organic fertilizer for plant nutrients. In this research, poultry litter was converted into biochar, which offers a range of possible applications, including analyzing […]
