Diminishing of fossil fuels cause the price of it becomes highly expensive and due to
that it becomes less attractive to be the source of fuels especially in transportation
sector. Thus most study is focus on searching the alternatives as the demands of it is
also increasing day by day. The second generation of fuels production is biomass.
However, the cost of raw biomass is also expensive that make the products also
expensive. Now most researcher moving to third generation of fuels production that
is lignocellulosic biomass. It is non value materials which is the residue of forestry
has possibility to be one of the alternatives to the diminishing of fossil fuels. In this
study,it will be discussed the lignocellulosic biomass, the conversion process of
lignocellulosic biomass, pre treatment process and the modification on the pre
treatment in order to produce low cost pre treatment and less time consuming
