The oleaginous and lignocellulosic biorefinery stages present today different levels of developments going from laboratory research, to pilot and demonstration level, and to commercialization (Figure 5.8). 

Lignocellulose biorefinery (see Figure 17.6) processes include lignocellulosic biomass from different sources agricultural residues and wood. A lignocellulose biorefinery can be run either as a thermochemical or as a biochemical unit.

The concept of a lignocellulosic biorefinery is significantly attractive since it is associated with the major advantage of the low cost of the feedstock. The different types of low-cost feedstocks such as straw, wood, grass (including bamboo), paper waste, etc. may be utilized. It is well known in the literature that lignocellulosic feedstock has a potential for several applications, and it is shown schematically in the following Fig. 21.1.
