A new lignin source for high-value products

NARA is optimizing a conversion process that converts the carbohydrates in woody biomass into bio-jet fuel and other chemical products. Depending on the tree species, up to 60% of the dry weight of wood is carbohydrates. That leaves the remaining 40% of the woody biomass as a byproduct. In order to maximize the economic sustainability of a wood-to-biofuel industry, converting the …more

Transporting Biomass



An initial techno-economic analysis for the NARA biojet scenario has been completed. With the premise of constructing totally new facilities and current feedstock availability and costs, we estimate the manufacturing cost to produce biojet fuel derived from woody residuals at 2-3 times above the current market price for petrochemical-based jet fuel. Our current efforts are now aimed at reducing this initial cost estimate on many fronts. In the …more
