Biomass available in abundance from the agricultural crop residues such as rice straw, sugarcane bagasse, rice husk etc. are considered to be one of the main renewable energy resources that has great potential to complement the various non-renewable energy resources and can contribute to bioenergy supplies in the world. Although, these residues looks different but all of lignocellulosic nature i.e they are composed of cellulose, hemicellulose and lignin and being of lignocellulosic nature their physiochemical structure and other composition factors provides hindrance in the hydrolysis process to convert the cellulose into the fermentable sugars and other organic compounds and slows down the digestibility through the anaerobic digestion process.So, pretreatment of biomass is the first step for conversion of these residues into biofuels. As pretreatment disrupts the crystalline structure of macro and microfibrils and makes hydrolysis process effective. A number of pretreatment techniques are available at present and are under investigation in laboratory and pilot-plant scales. This paper overviews the various pretreatment methods of Lignocellulosic biomass.
