abstract
It can be argued that the success, sustainability, and security of a U.S. biofuels industry will not be based on only one or two biomass feedstocks available across the U.S. Rather, biomass production logistics (availability, supply, timeliness) and economics will in all likelihood demand that a core of biomass materials particular to given U.S. geographical regions will be feedstocks into bioconversion facilities for a year-round operation. With estimated annual supplies of 120, 377, and 446 million dry tons, respectively, forestry residues, agricultural crop residues, and dedicated energy crops will comprise this core. The variability in the feedstock properties can be minimized, their thermochemical value enhanced, and the consistency of the biofuel produced be assured by mixing with biological waste streams such as food processing residuals. This processing mindset opens a great opportunity to integrate all biomass including forestry, agricultural, and food processing residuals for bioenergy/biofuels production.
