Key ideas in Green ChemistryAdapted from "the Twelve Principles of Green Chemistry" by Paul T. Anastas, an organic chemist working in the Office of Pollution Prevention and Toxins at the EPA, and John C. Warner (1991).
•It is better to prevent waste than to treat or clean up waste
•It is better to minimize the amount of materials used and to recycle
•it is better to use renewable materials when it makes sense
•It is better to use or make non-toxic chemicals and ‘eco-friendly’ products
•It is better to use less energy
•It is better to use catalysts or any efficient means possible
•It is better to prevent accidents than it is to clean up accidents
Why use Green Chemistry?

The demand for Energy is the Problem
The demand for Energy is the Problem
• Since the industrial revolution, people have been polluting the world at an ever increasing rate
The demand for Energy is the Problem
• Since the industrial revolution, people have been polluting the world at an ever increasing rate
• Global CO2 levels have been increasing ever since – Now just over 401.57 ppm

Sustainable and Renewable Energy
• The Future holds new revolutions in energy generation, from solar power windows to clean nuclear fusion, just to name a few!
First solar panel windows (EPFL)
École polytechnique fédérale de Lausanne, CH (Switzerland)
Future homes and offices will control natural sunlight via optofluidics for saving energy
What you can do:
• Save energy whenever possible at home or at work – be efficient!!
• Reduce, Reuse, Recycle
• Learn, get involved, support research and discovery, educate others
• Invent new cleaner technology
Thank you!
