Twelve Principles of Green Chemistry
Understanding the twelve principles of green chemistry is essential for recognizing their applications in various sectors. These principles guide scientists and engineers to create processes that are both efficient and environmentally friendly. The following are the key principles:
- Prevention: It is better to prevent waste than to treat or clean up waste after it is formed.
- 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: 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 preserve efficacy of function while reducing toxicity.
- Solvent-free Processes: Whenever practicable, auxiliary substances (solvents, separation agents, etc.) should be eliminated.
- Energy Efficiency: Energy requirements should be recognized for their environmental and economic impacts and should be minimized. If possible, synthetic methods should be conducted at ambient temperature and pressure.
- Renewable Feedstocks: A raw material should be renewable rather than depleting whenever technically and economically practicable.
- Reduce Derivatives: Unnecessary derivatization (blocking group, protection/deprotection, etc.) should be minimized or avoided if possible.
- Catalysis: Catalytic reagents (as selective as possible) are superior to stoichiometric reagents.
- Design for Degradation: Chemical products should be designed so that at the end of their function they break down into innocuous degradation products and do not persist in the environment.
- Real-time analysis for pollution prevention: Analytical methodologies need to be further developed to allow for real-time, in-process monitoring and control prior to the formation of hazardous substances.
- Inherently safer chemistry for accident prevention: Substances and the form of the substance used in a chemical process should be chosen to minimize the potential for chemical accidents, including releases, explosions, and fires.
Reducing Hazardous Substances in Chemical Processes
The implementation of green chemistry principles leads to a notable reduction of hazardous substances in chemical processes.
