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.

How green chemistry differs from cleaning up pollution?

Green chemistry reduces pollution at its source by minimizing or eliminating the hazards of chemical feedstocks, reagents, solvents and products.

1. Prevent waste

2. Maximize atom economy

3. Design less hazardous chemical synthesis

4. Design safer chemicals and products.

5. Use safer solvents and reaction conditions.

6. Increase energy efficiency

7. Use renewable feedstocks

8. Avoid chemical derivatives

9. Use catalysts, not stoichiometric reagents

10. Design chemicals and products to degrade after use

11. Analyze in real time to prevent pollution

12. Minimize the potential for accidents

For those who are creating and using green chemistry, the hierarchy looks like this:

Source Reduction and Prevention of Chemical Hazards

*Chemicals that are less hazardous to human health and the environment are:

Global warming isn't a prediction. It is happening.
