Explain in detail the strategies adopted in Green Chemistry to avoid environmental pollution.

Explanation

The over exploitation of the soil using fertilisers and pesticides polluted the soil, water and air. But farming, irrigation etc. cannot be stopped. Then methods to reduce the environmental pollution must be developed.
Generally in a reaction some by-products are formed. In many processes these by-products become the pollutants. Green chemistry work for not producing wasteful by product in these processes.
Normal Process :
`underset("Reactant")(A) + underset("Reactant")(B) rarr underset("Product")(C) + underset("Waste by product")(D)" "...(1)`
According to green chemistry the process shall be
`underset("Reactant")(A) + underset("Reactant")(B) rarr underset("Product")(C)" "...(C)`
As the reaction (2) gives no by-product it is called an environmental friendly reaction. Even if a by-product is formed, it must be made a useful product instead of polluting the environment. Green chemistry suggests that instead of using conventional fuels and energy systems, non-conventional fuels and non-conventional systems must be put into practice. Because of this, pollution would be reduced.
