Detailed explanation-1: -Green chemistry is the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. Green chemistry applies across the life cycle of a chemical product, including its design, manufacture, use, and ultimate disposal.
Detailed explanation-2: -Definition of Green Chemistry Green chemistry involves a reduction in, or elimination of, the use of hazardous substances in a chemical process or the generation of hazardous or toxic intermediates or products. This includes feedstock, reagents, solvents, products, and byproducts.
Detailed explanation-3: -Green chemistry is an approach that aims to eliminate the usage and generation of hazardous substances by designing better manufacturing processes for chemical products. Specifically, the goal of making the finished product and by-products less toxic directs the decisions made during chemical production.
Detailed explanation-4: -Prevention. It is better to prevent waste than to treat or clean up waste after it has been created. Atom Economy. Less Hazardous Chemical Syntheses. Designing Safer Chemicals. Safer Solvents and Auxiliaries. Design for Energy Efficiency. Use of Renewable Feedstocks. Reduce Derivatives. More items
