Green Chemistry

Green Chemistry -Green Chemistry is the design of chemical products and processes that reduce or eliminate the use and/or generation of hazardous substances. The 12 Principles of Green Chemistry - 1. Prevention of waste 2. Atom Economy 3. Less Hazardous Chemical Synthesis 4. Designing Safer Chemicals 5. Safer solvents and auxiliaries 6. Energy efficient 7. Renewable feedstocks 8. Reduce derivatives 9. Catalysis 10. Design for degradation 11. Real time analysis for pollution prevention 12. Safety Pathways to Green Chemistry- Chemical Manufacturers • Create new ways to make desired materialsdifferent feedstocks, different pathways • Identify desired performance characteristics and create new materials Benefits of Using Biomass- • Renewable Feedstock • Contributes no net CO2 to the atmosphere • Conserves fossil fuel leading to a secure domestic supply • Platform for making an array of chemical products from what is otherwise considered waste.
