Difficult ethical and political issues confront the application of
scientific and technological solutions for preventing pollution from
occurring. Often the questions embodying proposed solutions to known
problems are ambiguous; and no singular solution can exist for all
locations. Yet the common organizing principle for all solutions to
environmental problems must be scientific, because only sound science
can provide a rational understanding that decision-makers can use
universally. The NATO Advanced Research Workshop (ARW) on Tools and
Methods for Pollution Prevention (October 12-14, 1998, Prague, Czech
Republic) was designed to assemble experts from NATO and former
socialist countries of Eastern Europe to discuss science-based tools and
methods, either available or in development, that can be used to analyze
environmental impacts of manufacturing processes and manufactured
products. The presentations at the workshop were written up specifically
for the purpose of this book, albeit after peer reviews and thorough
revisions. Most of the chapters focus on specific method development for
designing environmentally benign processes or products. Several chapters
take a broader view and focus on such designs from an implementation
perspective, and dwell on ethical conflicts, resistance to change
because of inertia or inadequate infrastructure, and on the lack of
resources. We placed these chapters at the beginning of the book. The
volume starts with the overview by Sikdar et aI., who describe the scope
and difficulties of pollution prevention in the manufacturing sectors.
