The shifting of dependence from conventional fuels to renewable fuels and its increased production to combat the energy, environmental, and geopolitical crises is a global concern. One of the viable and promising alternatives is liquid biofuel production using lignocellulosic biomass. Lignocellulosic biomass being the most abundant encompass cellulose, hemicellulose, and lignin.The intricate complex of hemicellulose and lignin around cellulose is the bottleneck in commercializing the biofuel process. To make the cellulose and hemicellulose more accessible for hydrolysis and valorise the underutilized lignin for platform chemical production, pretreatment becomes imperative. Various pretreatment methods such as physical, mechanical, chemical, biological, and enzymatic and their combinations are employed for the production of bioethanol. It should be stressed that each pretreatment is unique in its condition and in most cases are biomass specific. With the above view, this chapter aims at bringing out the understanding of lignocellulosic pretreatment with updated information in the field.

Potential Of Lignocellulosic Feedstock For Biofuel Production

Agricultural residues and woody biomass, dedicated energy crops are the major source of biomasses which has the potential to meet the renewable energy demand in a more feasible and sustainable manner. The International Renewable Energy Agency (INRE) stipulates that, use of LCB for production of renewable energy will be doubled in 2030 when comparing 2010. The major share of 40% of renewable energy generation would come from agricultural residues and the remaining would be covered by energy crops and forest residues. Therefore, a huge demand of biomass supply is anticipated with Asia and Europe, including Russia, has been identified has potential suppliers.
