4. Definition of green chemistry
“Generation of new products and its process that
reduce or eliminate the use or generation of
Hazardous material”
Chemical
Process

5. Why do we need
Green Chemistry
•New environmental problems
•Harmful unexpected side effects
•A famous example is the pesticide DDT.

6. Is there any
advantages…??????
Eco-friendly
Energy efficient
Less wastages
Fewer accidents
Safer products
Easier cleanup
Healthier work places
More efficiency
Lower cost of production and regulation

7. Principles of Green chemistry
•Waste Prevention
•Improve Atom economy
•Less hazardous chemical synthesis
•Designing safer chemicals

8. •Use Safer solvent & Auxiliaries
•Design for energy efficiency
•Design for Degradation
•Use of Renewable Feed stocks
•Avoid chemical derivatives
•Use Selective catalysts
•Real time analysis for pollution prevention
•Safer chemistry
