This study was conducted to evaluate the efficacy of biomass and biomass-derived biochar from three different plant source such as Prosopis juliflora, Cocos nucifera (coconut fronds), Acacia moniliformis, and sugarcane bagasse. The calorific value, carbon content, sulfur content, and ash content were analyzed for all the biomass and synthesized biochar specimens. Physicochemical properties of the resulting biochar variants were thoroughly examined and the most suitable biochar was further characterized through high through put techniques FTIR, XRD, and SEM analyses. The findings indicated that biochar produced from Acacia moniliformis displayed superior characteristics in comparison to the other types of biomass investigated. These outcomes indicate the promise of Acacia moniliformis biochar as a viable sustainable energy source and emphasize its relevance in multiple aspects of sustainable energy production and environmental management.
