Proximate, ultimate and calorific value analyses were performed to know the energy perspective, whereas thermogravimetric analysis was used to study the decomposition behavior of biomass samples under pyrolysis conditions. The moisture content, volatile matter, fixed carbon and ash content in the biomass samples were found within the range of 4.38-5.69%, 63.25-80.53%, 7.97-23.13%, and 7.12-14.35%, respectively. The range of carbon, hydrogen, and oxygen content was reported as 35.83-47.23%, 5.2-6.56%, and 45.6-58.55%, respectively. Lower values of sulfur and nitrogen content amongst the samples indicated that the biomass was environmentally friendly in terms of energy production. The heating value of the biomass was reported in the range of 15.20-18.44 MJ/kg. Fourier transform infrared spectroscopy showed the existence of hydroxyl, aldehydes, ketones, aromatic compounds, carbonyl compounds, ether, and halogen groups. Orange leaf biomass indicated a greater potential in producing bio-oil, whereas the horticulture biomass and mango leaves may have greater potential for biochar.

more, it contains a negligible amount of sulfur and nitrogen, hence decreases certain environmental issues such as acid rains [12]. Due to being a cost effective alternative and with lower environmental emissions, biomass is an important fuel source. For the abovementioned attributes, the global scientific community is focusing research on the efficient utilization of biomass energy as an alternative renewable energy source [13,14]. Amongst biomass, lignocellulosic biomass is considered as a paramount source of energy production [15]. Different forms of energy such as biofuels, biochar and biogas can be produced from biomass, which can be further converted to other usef
