Green chemistry

Definition

Green chemistry is the design of chemical products and processes that minimize or eliminate the use and generation of hazardous substances. It aims to reduce the environmental and health impacts associated with chemical manufacturing and use, promoting sustainability through safer, more efficient methods. This approach not only addresses pollution prevention but also encourages innovation in developing materials and technologies that are less harmful to the environment.

5 Must Know Facts For Your Next Test

1. Green chemistry is built on 12 principles, including waste prevention, atom economy, and the use of renewable feedstocks.
2. One key goal is to develop processes that do not require toxic solvents or hazardous reagents, thereby reducing environmental contamination.
3. Green chemistry has led to the creation of safer alternatives for traditional chemicals used in products like cleaning supplies and personal care items.
4. It promotes energy efficiency by encouraging reactions that occur under milder conditions and utilizing renewable energy sources.
5. By implementing green chemistry principles, industries can often save money by reducing waste disposal costs and improving process efficiency.
