biofuels (bioalcohols, biodiesel, biohydrogen) are included, in addition to conventional fuels
that have been enzymatically treated to reduce the generation of pollutants.
6. Economics and Commercialization
In a market economy, the financial aspects of a new technology inevitably have a major
impact on its adoption. Indeed, the majority of technological limitations and research needs
described below derive their importance from the need to make pollution prevention
technologies competitive with their conventional counterparts. Nevertheless, as a review of
the state of the science, thorough analyses of the process economics of each technology are
beyond the scope of this work. Many excellent reviews of this aspect exist however, and are
cited in the text.

URPOSE
The purposes of this document are four-fold: first, to explore the realm of current and
developing technologies in the fields of biomaterials and biofuels that benefit environmental
integrity through their production and use; second, to identify the most promising and most
essential areas of endeavor within each field, thus highlighting top priorities for further
research and development; third, to examine the technological challenges and/or barriers to
the progress of the given technologies; and fourth, to elucidate the contributions of the
NSF/EPA's Technology for a Sustainable Environment Program for each topic area.
