“ Chemistry has an important role to play in achieving a sustainable civilization on earth.”

— Dr. Terry Collins, Professor of ChemistryCarnegie Mellon University

GREEN CHEMISTRY WORKS TOWARD SUSTAINABILITY BY:• Making chemical products that do

not harm health or the environment

• Using industrial processes that reduce or eliminate hazardous chemicals

• Designing more efficient processes that minimize the production of waste materials.

Examples of Green ChemistryRemoving Arsenic and Chromate from

pressure treated wood.Many new pesticides.New oxidants for bleaching paper and

disinfecting water.Getting the lead out of automobile paints.Recyclable carpeting.Replacing VOC’s (volatile organic

compounds) and chlorinated solvents.Biodegradable polymers from renewable
