IntroductionGreen chemistry is the design of chemical products and p
rocesses that reduce or eliminate the use or generation of h
azardous substances. The problem with modern chemist-ry i
s that traditional chemical processes often lead to air, wate
r and soil pollution. The generation of large volumes of toxic
waste, which requires costly and complex disposal. Relianc
e on fossil fuels (oil, gas, coal) as the primary raw materials
for chemical production.

IntroductionGreen chemistry offers innovative solutions to overcome t
he challenges associated with traditional chemistry by:
1) Preventing waste generation
2) Designing safer chemicals and processes
3) Using renewable resources
4) Reducing energy consumption
5) Increasing resource efficiency
