Green Chemistry is one of the most exciting and innovative approaches to come along in the chemical enterprise and environmental protection areas in a generation. Basically Green Chemistry is the design of chemical processes and products that reduce or eliminate the use and generation of hazardous substances. It is a global trend that involves research on new feedstocks, environmentally benign solvents, catalysis, synthetic methodologies, and greener products. This volume is a collection of the cutting-edge research being conducted in this area from scientists around the world, brought together for the first time in Green Chemistry: Challenging Perspectives. It provides an overview of the major issues facing chemists engaged in creating more environmentally responsible technology and processes, and will be of interest to scientists and decision-makers in industry, academia, and government.
