Green chemistry reduces pollution at its source by minimizing or eliminating the hazards of chemical feedstocks, reagents, solvents, and products. This is not the same as cleaning up pollution (also called remediation), which involves treating waste streams (end-of-the-pipe treatment) or cleanup of environmental spills and other releases. Remediati...
1. Prevent waste: Design chemical syntheses to prevent waste. Leave no waste to treat or clean up. 2. Maximize atom economy: Design syntheses so that the final product contains the maximum proportion of the starting materials. Waste few or no atoms. 3. Design less hazardous chemical syntheses: Design syntheses to use and generate substances with li...

In the federal Pollution Prevention Act of 1990, Congress declared that it is "the national policy of the United States that pollution should be prevented or reduced at the source whenever feasible; pollution that cannot be prevented should be recycled in an environmentally safe manner, whenever feasible; pollution that cannot be prevented or recyc...
Learn what green chemistry is and how it applies to chemical products and processes across their life cycle. Find out the 12 principles of green chemistry and how they prevent pollution at the molecular level.
Green chemistry, similar to sustainable chemistry or circular chemistry, is an area of chemistry and chemical engineering focused on the design of products and processes that minimize or eliminate the use and generation of hazardous substances.
- Prevention. It is better to prevent waste than to treat or clean up waste after it has been created.
- Atom Economy. Synthetic methods should be designed to maximize the incorporation of all materials used in the process into the final product.
- Less Hazardous Chemical Syntheses. Wherever practicable, 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 effect their desired function while minimizing their toxicity.
Mar 21, 2017 · 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. Green chemistry is also known as sustainable chemistry. Green chemistry:
Green chemistry is an approach to chemistry that aims to prevent or reduce pollution by modifying how chemicals are designed, manufactured, and used. Learn about the 12 principles of green chemistry, the concept of atom economy, and the Nobel Prize-winning work of Richard R. Schrock on metathesis.
