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
Risk &
Hazard
Materials
Reducing
Energy
From: James Clark, 2004
Waste
Nonrenewables
Packaging &
Plastics
Lubricants
Dyes & Pigments
Solvents
Fragrances &
Perfumes
Food additives
Pesticides
Research areas
relevant to consumer
products
Adhesives
Electronics
Flame
Retardants
Preservatives
Textiles & Fabric
Treatments
Surfactants
From: James Clark, 2004
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
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
Green chemistry is:
Scientifically sound
Cost effective
Leads toward a sustainable earth
