Synonymous with forestry activities and agriculture, waste generation has become a major issue of concern. Biomass has become an important sustainable and viable source of chemical energy capable of being converted into diverse energy manifestations whether through indirect or direct means. Globally, the integration of renewable options (biomass) into the energy stream continues to witness steady growth, catapulted by a range of factors which include minimal emissions, the quest for cleaner alternatives, heightened governmental provisions for renewable energy innovation, and the vast pool of unexplored prospects in biomass. In the context of Indian agriculture, which boast with a cropping intensity of over 140% and a cultivated area extending to 180 million hectares, a considerable volume of biomass is generated, with residues constituting a prominent share. In the Punjab region, biomass is readily available as agricultural waste throughout the year, which has been a persistent source of environmental pollution. This study aims to investigate the proximate and elemental composition of certain residues to evaluate their energy potential and blending suitability for heat and power generation. Poplar wood (Populus ciliata), eucalyptus wood (Eucalyptus globulus), sugarcane bagasse (Graminae Saccharum officinarum), coconut shell (Cocos nucifera), switchgrass (Panicum virgatum), and congress grass (Parthenium hysterophorus) were studied using thermochemical analysis; the ash content is 1.07 ± 0%, 1.38 ± 0.28%, 6.49 ± 0.51%, 9.75 ± 1.48%, 6.2 ± 0.28%, and 9.7 ± 0.42% respectively. Volatile matter for poplar was 73.65 ± 0.92%, eucalyptus was 74.3 ± 1.84%, and their respective conceptual heating values (HHV) were 18.23 MJ/kg and 16.80 MJ/kg.
