Green chemistry is the development of chemical products and processes that reduce or eliminate the use of hazardous compounds. Green chemistry applies to a chemical product's entire life cycle, including its design, manufacture, usage, and disposal. Sustainable chemistry is another name for green chemistry. The International Union of Pure and Applied Chemistry (IUPAC) defines green chemistry as "the design, development, and use of chemical products and processes to limit or eliminate the use and manufacture of harmful substances."Green chemistry is an interdisciplinary research field that combines knowledge from chemistry, chemical technology, biotechnology, molecular biology, ecology, and toxicity. The contributions from diverse disciplines can aid in the development of new and innovative technologies as well as environmentally friendly synthetic methods for chemical manufacturing.
