ABSTRACT
Cellulosic biomass such as wood, tall grasses, and forestry and crop residues are expected to significantly expand the quantities and types of biomass feedstock available for biofuel production in the future as new conversion technologies are developed that enable the production of biofuels from these feedstocks. Over the next 10 to 15 years, it is expected that lower-cost residue and waste sources of cellulosic biomass will provide the first influx of ‘next-generation’ feedstocks, with cellulosic energy crops expected to begin supplying feedstocks for biofuel production towards the end of this time-frame, then expanding substantially in the years beyond.
