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?

Why use Green Chemistry?

Currently the world is facing serious problems such as pollution, limited resources, and an ever increasing global energy demand

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

• 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

• And not to mention ozone depletion, smog, soot, cloud reflective index changes

The Energy Crisis – A global problem

• Demands are only increasing while fossil fuel sources are near exhaustion

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!
