Abstract: The present work focused on the energy coversion efficacy of leaves of bamboo sp. Viz., Bambusa balcooa, Dendrocalamus hamiltonii, Dendrocalamus asper. After Pyrolysis of biomass 1. Bambusa balcooa bio-oil was further analysed for fuel property and bio-physical characterization, 2. biochars from Bambusa balcooa, Dendrocalamus Hamiltonii were tested for heavy metal remedation and other soil amendment experimentation and 3. biochar and bio-tar from Dendrocalamus asper were used for energy efficient pallet formation. The chemical composition of pyrolytic oil consisted of phenolic compounds contributed towards acidity of bio –oil and its relative density was found 0.912, Kinematic viscosity of 4.72, Cloud and pour points were -9 and -18 0C respectively, Flash and fire points were 59.2 and 68.5 0C respectively, ash content was 0.11, Conradson Carbon residue was 9.6 and acid value was 13.5. Thermal kinetics modeling of Bambusa balcooa biomass drying using TGA showd that Henderson model was suitably fitted (Highest R2 values) and actiovation energy for initial drying was calculated around 64.45 kJ/mol.For the devolatization stage, activation energy was found 40.36 kJ/mol.Physical study (FTIR, SEM, BET) study showed that biochar from bamboo could be used for adsorption of heavy metals. Dendrocalamus hamiiltonii biochar had equilibrium time at 60 min for Co (II) ions and 30 min for Pb (II) ions, dosage of 0.6 g/100 m.l for Co and 0.5 g/100m.l for Pb, pH 7 for max-imum uptake of Co(II) ions and pH 5 for maximum uptake of Pb (II) found optimum. Second order kinetic model, Freundlich isotherm model was found suitable to adsorption process. Response Surface Methodology applied for the adsorption from zinc electrode wastewater by Bambusa balcooa biochar showed that the optimum adsorption conditions pH (A) = 7, Time (B) = 73.05 , Biochar Dose (C) = 0.98) with predicted adsorption 18.32% (Pb), 78.39% (Zn), 44.5% (Cd), 95.71%(Cr). Calorific value of pellet produced from biochar and biotar was in range of 20-30 MJ/Kg. Ammonia adsorption was higher (123.08%) in case of 1: 1 soil : biochar ratio. Bambusa balcooa biochar applied soil has 34% increment in water holding capacity than the untreated soil.Ethanol production from pretreated biomass of Bambusa balcooa leaves (Cellulose rich fractions) was done through biomass saccharification through Cellulases and Saccharomyces cerevisiae inoculation with an overall raw biomass to ethanol conversion efficiency was 36.72%.
