The definition of green chemistry is constantly changing. When it first appeared, it more represented an idea and a wish. However, with the development of the discipline, it gradually tends to practical application in the constant development and change, and its development is closely related to chemistry.
Green chemistry advocates using chemical techniques and methods to reduce or stop using and producing raw materials, catalysts, solvents and reagents, products and by-products harmful to human health, community safety and ecological environment.

Green chemistry originated in America. 1984, the United States Environmental Protection Agency (EPA) proposed "waste minimization". Its basic idea is to minimize waste by reducing waste generation and recycling, which initially embodies the idea of green chemistry. However, waste minimization can't cover all the concepts of green chemistry, it is just a chemical industry term, and it doesn't pay attention to the production process of green chemistry.
1989 The U.S. Environmental Protection Agency put forward the concept of "pollution prevention", pointing out that the waste produced in production sites should be reduced as much as possible, including reducing the use of harmful substances, using resources more effectively and protecting natural resources, and initially forming the idea of green chemistry.
