Abstract
The rapid industrialization, urbanization, and population explosion have resulted in increased energy consumption, resulting in growing credence on conventional fossil fuels (like coal and petroleum). The literature suggested that the fossil fuel reserve is diminishing rapidly and are also associated with the spectrum of entanglement like degradation of overall environmental quality, pressure on global treasury etc. On the contrary, clean and carbon neutral energy sources are an excellent alternative in this critical scenarioof energy crisis due to their greater abundance and carbon neutrality. Accordingly, a biomass-based energy recovery system has substantiated potential in this cognizance. Waste biomass is a particular biomass class that has gained significant research engrossment in the utilization of feedstock in energy recovery applications. However, a biomass-based energy recovery system is often reported to be uneconomical. Hence a sustainable approach of custom-made technologies should be taken towards this end by harnessing the colossal biomass reserve to generate power from then in a cost-beneficial and eco-friendly manner. The present study focuses on the impact of chemical pre-treatment (chosen in the form of sulphuric acid) on various energetic properties of waste biomass (chosen in the form of sugarcane bagasse). The waste biomass's compositional analysis, bulk density, ultimate & proximate analysis, and calorific value (in terms of higher heating value or HHV) were carried out after dilute acid pre-treatments by following standard procedures as cited in literature. The obtained results indicated that dilute acid pre-treatment has significant potential for better energy recovery potential. Maximum rise in the various properties was for acid pre-treatment with 5% acid. This study can greatly favour the upcoming headway and further scaling-up of the biomass-based energy harvesting technology promoting sustainable societal advancement.
