Page 6: A Greener Approach

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?

Page 8: A Greener Approach

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

Page 12: A Greener Approach

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

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

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

• 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

• Pollution has severe ecological and climatological impacts on the entire world

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

• Pollution has severe ecological and climatological impacts on the entire world

• Energy usage is the primary driver of climate change

• Energy usage is the primary driver of climate change

• Soil contamination, water pollution, acid rain, rapid deforestation

The Energy Crisis – A global problem

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

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!
