Green Chemistry

Green chemistry is set of principals whose purpose is to guide and regulate the production and use of new chemical undertakings in all facets of human life.  These principals are as follows.  Prevention: it is better to prevent waste than to treat or clean up waste after it has been created.  Atom Economy, where synthetic methods should be designed to maximize the incorporation of all materials used in the process into the final product with as little waste as possible.  Less Hazardous Chemical Syntheses: where ever practical, synthetic methods should be designed to use and generate substances that possess little or no toxicity to human health and the environment.  Designing Safer Chemicals: chemical products should be designed to affect their desired function while minimizing their toxicity.  Safer Solvents and Auxiliaries: the use of auxiliary substances (solvents, separation agents, etc.) should be made unnecessary wherever possible and innocuous when used.  Design for Energy Efficiency: energy requirements of chemical processes should be recognized for their environmental and economic impacts and should be minimized.  If possible synthetic methods should be conducted at ambient temperature and pressure.  These principals set the guidelines used by chemical companies all over the world to allow for safe and environmentally friendly use and production of chemical products
