To find out more about these feedstocks and others--and about how feedstocks are used to make advanced biofuels, how the research is progressing, and what challenges face us, click on the Feedstock or R&D Feedstock categories along the right margin of each page.
OR, search by the name of the feedstock that interests you.
OR, take a look at the Handbook of Energy Crops on Purdue University's newCROPS web site:
"During the last decade, biomass advocates have suggested numerous plant species as sources of firewood, vegetable seed oil, fermentation substrates, and whole-plant hydrocarbons. However, the rationale for selecting one species over another is, with few exceptions, sketchy, ambiguous, or unavailable. James A. Duke in the "Handbook of Energy Crops" has brought together in one source information common to about 200 species most frequently proposed for energy production. The Handbook provides discussion and presentation of available information such as: nomenclature, uses, folk medicine, chemical composition, botanical description, germplasm, distribution, ecology, cultivation, harvesting, yields and economics, energy, biotic factors, and key references. The technologist, attempting to identify plant species that merit further attention or show promise for satisfying specific fuels, chemicals, and materials needs, should find this an invaluable reference source."
