Summary

Cellulosic biofuels offer potentially greater environmental benefits relative to biofuels made from annual crops, including lower net greenhouse gas emissions, improved water use efficiency and water quality, reduced soil erosion, enhanced soil fertility, and more positive biodiversity attributes. There are two primary barriers to realizing the potential of cellulosic biofuels on a large scale: (1) the recalcitrance of cellulosic biomass and (2) land-use concerns, especially those regarding competition with food production. Overcoming this recalcitrance is the central challenge to large-scale commercial production of cellulosic biofuels. This chapter describes two broad categories of conversion technologies exist for producing cellulosic biofuels: thermochemical and biological. Then, it talks about the pretreatment of cellulosic biomass.
