TI - Biomass as Feedstock for a Bioenergy and Bioproducts Industry: The Technical Feasibility of a Billion-ton Annual Supply

AB - This report assesses whether U.S. land resources could sustainably supply enough biomass to significantly reduce petroleum consumption through biofuels and biobased products. Motivated by a federal vision to replace roughly 30 percent of U.S. petroleum use by 2030, the analysis evaluates whether approximately one billion dry tons of biomass feedstock could be produced annually under plausible economic, technological, and land-use conditions. The study finds that the United States has sufficient biomass potential to meet this goal. Focusing on forest and agricultural lands, it identifies more than 1.3 billion dry tons per year of sustainable biomass potential—enough to supply over one-third of current transportation fuel demand. Forestlands could contribute roughly 368 million dry tons annually from fuelwood, processing residues, urban wood waste, logging and site-clearing residues, and fuel treatment operations. Agricultural lands could supply nearly one billion dry tons per year through crop residues, perennial energy crops, grains used for biofuels, animal manures, and other processing residues, while continuing to meet food, feed, and export requirements. These estimates rely on a set of explicit assumptions regarding yield improvements, residue recovery, no-till farming practices, dedicated acreage for perennial energy crops, and sustainable forest management. The results suggest that achieving a billion-ton annual biomass supply would require substantial but feasible changes in agricultural and forestry practices, rather than radical land-use transformation. The report emphasizes that this scenario is not an upper bound, but a conservative estimate intended to inform long-term planning for bioenergy, biorefineries, and national energy security.

Abstract
This report assesses whether U.S. land resources could sustainably supply enough biomass to significantly reduce petroleum consumption through biofuels and biobased products. Motivated by a federal vision to replace roughly 30 percent of U.S. petroleum use by 2030, the analysis evaluates whether approximately one billion dry tons of biomass feedstock could be produced annually under plausible economic, technological, and land-use conditions. The study finds that the United States has sufficient biomass potential to meet this goal. Focusing on forest and agricultural lands, it identifies more than 1.3 billion dry tons per year of sustainable biomass potential—enough to supply over one-third of current transportation fuel demand. Forestlands could contribute roughly 368 million dry tons annually from fuelwood, processing residues, urban wood waste, logging and site-clearing residues, and fuel treatment operations. Agricultural lands could supply nearly one billion dry tons per year through crop residues, perennial energy crops, grains used for biofuels, animal manures, and other processing residues, while continuing to meet food, feed, and export requirements. These estimates rely on a set of explicit assumptions regarding yield improvements, residue recovery, no-till farming practices, dedicated acreage for perennial energy crops, and sustainable forest management. The results suggest that achieving a billion-ton annual biomass supply would require substantial but feasible changes in agricultural and forestry practices, rather than radical land-use transformation. The report emphasizes that this scenario is not an upper bound, but a conservative estimate intended to inform long-term planning for bioenergy, biorefineries, and national energy security.
