  1. Green Chemistry- Preventing Pollution. Sustaining the earth. Sheri J. Tonn June 2008

  2. Green Chemistry Award Winners • http://www.epa.gov/greenchemistry/pubs/pgcc/past.html

  3. Benefits of the Chemical Industry From: James Clark, 2004

  4. Danger! Pollution Disease Depletion of natural resources Waste Disposal CHEMISTRY- A Dirty Word! Toxic Emissions Cancer Land Fill Accidents From: James Clark, 2004

  5. What is Green Chemistry? • Green chemistry is the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances • Discovery and application of new chemistry/technology leading to prevention/reduction of environmental, health and safety impacts at source • It can be considered as a set of reductions: Cost Materials Risk & Reducing Energy Hazard From: James Clark, 2004 Non- Waste renewables

  6. Research areas relevant to consumer products Packaging & Plastics Lubricants Dyes & Pigments Solvents Fragrances & Perfumes Pesticides Adhesives Food additives Electronics Textiles & Fabric Treatments Preservatives Flame Retardants Surfactants From: James Clark, 2004

  7. The Twelve Principles of Green Chemistry • Synthetic methods should incorporate all materials possible into the final product • Prevent rather than treat or clean up waste • Use and generate substances with little or • No toxicity • Preserve efficacy while reducing toxicity

  8. Reduce auxiliary substances • Recognize energy use for environmental and economic impacts and reduce • Raw materials should be renewable • Avoid unnecessary derivatives during synthesis • Use catalysts • Make non-persistent chemicals • Use real-time monitoring and process control • Minimize potential for accidents, releases, explosions, fires

  9. Green chemistry is: • Scientifically sound • Cost effective • Leads toward a sustainable earth
