Bioethanol—Lignocellulosic Sugar Platform
Renewable transportation fuel produced from the hydrolysis and fermentation of glucose, xylose and other fermentable carbohydrates found in the cellulose- and hemicellulose-rich fractions of "biomass."

Bioethanol—Thermo-Chemical Platform
Renewable transportation fuel produced from the fermentation of a mixed carbon monoxide, carbon dioxide and hydrogen stream generated from the gasification of biomass, MSW and other carbon-rich substrates.

Biodiesel
A renewable transportation fuel produced from the esterification of lipid-rich (oil or fat) agricultural commodities and food processing residues.

Biogas
A renewable methane-rich fuel produced from the bacterial anaerobic digestion of agricultural and food processing wastes, manure, and bioethanol and biodiesel processing residues.

Bioethanol Derivative Chemistries
Products derived from existing and potential bio-based chemicals—made from or during the production of sugar- and starch-based bioethanol and its co-products.

Biodiesel Derivative Chemistries
Products derived from existing and potential bio-based chemicals—made from or during the production of oil seed-based biodiesel and its co-products.
