Nicht nur in den westlichen Industrieländern ist Umweltschutz heute ein selbstverständlicher Bestandteil der gesellschaftlichen Existenz. Über die Entwicklung der Grünen Chemie und Technik informiert das 9-bändige "Handbook of Green Chemistry" (herausgegeben von Paul Anastas, dem Vater der Grünen Chemie), zu dem dieser vorliegende Band über superkritische Lösungsmittel gehört. Ausführlich wie nie zuvor behandelt er alle Aspekte dieses aufregenden Forschungsgebiet.

About the author
Paul T. Anastas joined Yale University as Professor and iserves as the Director of the Center for Green Chemistry and Green Engineering at Yale. From 2004-2006, Paul Anastas has been the Director of the Green Chemistry Institute in Washington, D.C. Until June of 2004 he served as Assistant Director for Environment at e White House Office of Science and Technology Policy where his responsibilities included a wide range of environmental science issues including furthering international public-private cooperation in areas of Science for Sustainability such as Green Chemistry. In 1991, he established the industry-government-university partnership Green Chemistry Program, which was expanded to include basic research, and the Presidential Green Chemistry Challenge Awards. He has published and edited several books in the field of Green Chemistry and developed the 12 principles of Green Chemistry.
