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 (35–50%),
hemicellulose (20–35%) and lignin (5–30%). In this work, hydrolysis of cellulosic bamboo biomass (CBB) was investigate
for sugar production using the most commonly known hydrophilic ionic liquid, 1-butyl-3-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 dilute sulphuric acid. The effect of pretreatment
steps on the crystallinity index, morphology, chemical, thermal properties, ultimate and proximate properties was investigated
using XRD, SEM, FTIR, TGA and Elemental analysis characterization techniques. The amount of total reducing sugar (TRS)
produced was determined by 3, 5-dinitrisalcylic acid (DNS) method using UV-Visible spectroscopy. It was observed that CBB
prior dissolution in [BMIM] Cl, effectively enhanced the yield of TRS (80%).
