Pyrolysis temperature induced changes in characteristics and chemical composition of biochar produced from conocarpus wastes

► Conocarpus wastes were pyrolyzed at different temperatures of 200, 400, 600 and 800 °C. ► Biochar produced at high pyrolysis temperature enjoys higher carbon stability compared to that obtained at low temperature. ► Biochar produced at high pyrolysis temperature may possess a higher carbon sequestration potential when applied to the soil.
