Green chemistry and environmental technology applications in everyday life

T.Srikumar, M.C.Rao

The principles of green chemistry guide firms in designing new products and processes in such a way that their impact on the environment is reduced. Green chemistry is the new and rapid emerging branch of chemistry for the environment. It is really a philosophy and way of thinking that can help chemistry in research and production to develop more eco-friendly solutions. Green chemistry is a science based non-regulatory and economically driven approach to achieve the goals of environmental protection and sustainable development. All chemical wastes should be disposed of in the best possible manner without causing any damage to the environment and living beings. Another way to save the environment through sustainable chemistry is to make use of renewable food stocks. Chemical derivatives must be avoided as far as possible in any type of application as they often prove to be harmful. Large amounts of adipic acid are used each year for the production of nylon, polyurethanes. The glucose can be converted into adipic acid by an enzyme discovered in genetically modified bacteria. The use of supercritical fluids (SCFs) in chemical processes is becoming more and more prevalent. Carbon dioxide as a supercritical fluid is most frequently used as medium for reactions. It is inflammable, easily available and cheap. The discovery of supercritical carbon dioxide opened a way to new processes in textile and metal industries and for dry cleaning of cloth. This article presents selected examples of implementation of green chemistry principles in everyday life in industry and in domestic purpose.
