Non-renewability of fossil fuels and the challenges associated with its utilization such as price fluctuation due to political instability of oil rich regions, environmental concerns, imbalance between energy supply and population growth and uneven distribution of these resources in the globe are some of the compelling factors to research for sustainable and renewable energy resources. Biomass is one of the most promising candidate along with solar, wind and hydrothermal energies for sustainable and renewable energy demand. Being the most abundant and bio-renewable resource, lignocellulosic biomass has the potential to serve as feed stock for the production of second generation bioethanol and platform chemicals without computing with food supply. Lignocellulosic biomass is composed of three bio-polymeric components: cellulose (35â??50%), hemicellulose (20â??35%) and lignin (5â??30%). In this work, hydrolysis of cellulosic bamboo biomass (CBB) was investigate for sugar production using the most commonly known hydrophilic ionic liquid, 1-butyl3-methyl imidazolium chloride ([BMIM] Cl), in the presence of sulphuric acid. CBB was regenerated from the alkaline pre-treatment of bamboo biomass and subsequently dissoloution in [BMIM] Cl and was then hydrolyzed using sulphuric acid. The effect of [BMIM] Cl prior dissolution on the crystallinity index, morphology, chemical and thermal properties was investigated using XRD, SEM, FTIR and TGA characterization methods. The amount of total reducing sugar (TRS) produced was determined by 3, 5-dinitrisalcylic acid (DNS) method using UV-Visible spectroscopy. Glucose, cellobiose and 5-hydroxylmethylfurfural were analysed using high performance liquid chromatograph. It was observed that CBB prior dissolution in [BMIM] Cl, effectively enhanced the yield of TRS (90%).
