##12 #Principles of Green Chemistry👇👇
1.🙅Prevention – It is better to prevent waste than to treat or clean it up. 
2. 🛣️Atom Economy – Maximize the incorporation of all materials into the final product. 
3.🥢Less Hazardous Chemical Syntheses – Use and generate substances with little or no toxicity. 
4. 🍯Designing Safer Chemicals – Create products that are effective but minimize harm. 
5.🥛Safer Solvents & Auxiliaries – Use safer solvents, separation agents, and other auxiliary substances. 
6.🔥Design for Energy Efficiency – Minimize energy use by optimizing reaction conditions. 
7.🌲Use of Renewable Feedstocks– Use raw materials that are renewable rather than depleting. 
8. 🌝Reduce Derivatives – Avoid unnecessary derivatization (blocking groups, protection/deprotection). 
9.🍟Catalysis – Use catalytic reagents (which can be reused) over stoichiometric reagents. 
10.🖌️Design for Degradation – Ensure chemical products break down into harmless substances. 
11. ✅Real-time Analysis for Pollution Prevention – Monitor reactions to prevent hazardous by-products. 
12. ✅Inherently Safer Chemistry for Accident Prevention – Choose chemicals and processes that minimize risks like explosions or fires.
