Green chemistry is the utilization of a set of principles that will help to reduce the use and generation of hazardous substances during the manufacture and application of chemical products. It aims to protect the environment not by cleaning up, but by inventing new chemical processes that do not pollute the environment. There are twelve principles of Green Chemistry which includes pollution prevention, atom economy, less hazardous chemical synthesis, designing safer chemicals, safer solvents and auxiliaries, design for energy efficiency, use of renewable feedstock, reduce derivatives, catalysis, design for degradation, real-time analysis for pollution prevention, inherently safer chemistry for accident prevention. It is a rapidly developing and an important area in the chemical sciences. As a chemical philosophy, green chemistry applies to organic chemistry, inorganic chemistry, biochemistry, analytical chemistry and even physical chemistry. Due to increasing local and global concern for environmental pollution green materials can be characterized in three parts: Green reagents (Dimethyl carbonate, Polymer supported reagents), Green catalysts (Acid Catalyst, Oxidation Catalyst, Basic Catalyst, Photo catalyst, Phase transfer Catalyst, Polymer supported catalyst, Biocatalyst) and Green solvents (Supercritical CO2, Water, Ionic liquids). Emerging techniques, in the overall development of “Green Chemistry”, can be categorized in following parts like Photochemistry, Microwave Chemistry, Sonochemistry and Electrochemistry. So Green chemistry is about waste minimisation of resources, use of catalysts in place of reagents, using non-toxic reagents, use of renewable resources, improved atom efficiency and use of solvent free or recyclable environmentally benign solvent systems.
