  3. 3. <ul><li>Consider that there are some 85,000 synthetic chemicals approved for commercial use in the U.S., and in one industry alone — cosmetics and personal care — there are an estimated 12,000 chemicals in use. </li></ul>Source:,“The State of Green Business,”: (2009) Toxics in Manufacturing <ul><ul><li>Any attempt to gather a reasonable list of chemicals to track is challenging at best. </li></ul></ul>
  4. 4. Green Chemistry is…
  5. 5. <ul><li>It represents a major paradigm shift that focuses on environmental protection at the design stage of product and manufacturing processes. </li></ul><ul><ul><li>It is an innovative way to deal with chemicals before they become hazards, with the goal of making chemicals and products “benign by design.” </li></ul></ul><ul><ul><li>For example, if the chemical synthesis is not compromised, which of the two chemicals below should we use? </li></ul></ul>Source: California Green Chemistry Initiative: (2008) Why Green Chemistry? OR Carcinogenic non-Carcinogenic
  6. 6. <ul><li>Green chemistry is an opportunity to spur the next industrial revolution through human ingenuity and creativity. </li></ul><ul><li>Advancing green chemistry is an opportunity to make a safer and more efficient world with less waste. </li></ul>Green Chemistry Benefits Source: California Green Chemistry Initiative: (2008)
  7. 7. Green Chemistry Principles
  8. 8. <ul><li>Prevention </li></ul><ul><ul><li>It is better to prevent waste than to treat or clean up waste after it has been created. </li></ul></ul><ul><li>Atom Economy </li></ul><ul><ul><li>Synthetic methods should be designed to maximise the incorporation of all materials used in the process into the final product. </li></ul></ul><ul><li>Less Hazardous Chemical Synthesis </li></ul><ul><ul><li>Wherever practicable, synthetic methods should be designed to use and generate substances that possess little or no toxicity to people or the environment. </li></ul></ul>The 12 Principles of Green Chemistry
  9. 9. <ul><li>Designing Safer Chemicals </li></ul><ul><ul><li>Chemical products should be designed to effect their desired function while minimising their toxicity. </li></ul></ul><ul><li>Safer Solvents and Auxiliaries </li></ul><ul><ul><li>The use of auxiliary substances (e.g., solvents or separation agents) should be made unnecessary whenever possible and innocuous when used. </li></ul></ul><ul><li>Design for Energy Efficiency </li></ul><ul><ul><li>Energy requirements of chemical processes should be recognised for their environmental and economic impacts and should be minimised. If possible, synthetic methods should be conducted at ambient temperature and pressure. </li></ul></ul>The 12 Principles of Green Chemistry
  10. 10. The 12 Principles of Green Chemistry <ul><li>Design for Degradation </li></ul><ul><ul><li>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. </li></ul></ul><ul><li>Real-time Analysis for Pollution Prevention </li></ul><ul><ul><li>Analytical methodologies need to be further developed to allow for real-time, in-process monitoring and control prior to the formation of hazardous substances. </li></ul></ul><ul><li>Inherently Safer Chemistry for Accident Prevention </li></ul><ul><ul><li>Substances and the form of a substance used in a chemical process should be chosen to minimise the potential for chemical accidents, including releases, explosions, and fires. </li></ul></ul>
  11. 11. The 12 Principles of Green Chemistry <ul><li>Use of Renewable Feed stocks </li></ul><ul><ul><li>A raw material or feedstock should be renewable rather than depleting whenever technically and economically practicable. </li></ul></ul><ul><li>Reduce Derivatives </li></ul><ul><ul><li>Unnecessary derivatization (use of blocking groups, protection/de-protection, and temporary modification of physical/chemical processes) should be minimised or avoided if possible, because such steps require additional reagents and can generate waste. </li></ul></ul><ul><li>Catalysis </li></ul><ul><ul><li>Catalytic reagents (as selective as possible) are superior to stoichiometric reagents. </li></ul></ul>
  12. 12. How it Fits in the Sustainability Framework Green chemistry relies upon lifecycle thinking to bring their concepts to fruition; it serves to achieve the ultimate goal of a sustainable economy and society.
  13. 13. Life Cycle Thinking

  16. 16. Conclusion <ul><li>The use of toxic chemicals in society is significant </li></ul><ul><li>Green Chemistry aims to reduce or eliminate the generation of toxics in manufacturing processes </li></ul><ul><ul><li>It is a subset of Life Cycle Thinking </li></ul></ul><ul><ul><li>It is an innovative way to deal with chemicals before they become hazards, with the goal of making chemicals and products “benign by design.” </li></ul></ul>
