Green chemistry is promoting a healthy environment for human society. Being responsible citizens we all should follow this. A world free from pollution will improve living conditions and increase the age of life on this planet. We have seen the importance of green chemistry and its application in daily life. It has many applications in our day-to-day life. The following points will show its uses:

Dry cleaning of clothes:  In earlier days tetrachloroethylene was used as a solvent for dry cleaning. This compound is carcinogenic and also pollutes the groundwater. Nowadays, liquefied carbon dioxide with suitable detergent is used for this purpose. It generates liquid carbon dioxide as a by-product and hence causes less pollution.

 Bleaching of paper: Initially chlorine gas was used for this purpose but now it has been replaced by hydrogen peroxide (H2O2). Hydrogen peroxide along with a suitable catalyst which promotes its bleaching action is used.

In 2005 Ryoj Nojori identified three key development in green chemistry: use of supercritical carbon dioxide as green solvent, aqueous hydrogen peroxide for clean oxidations and use of hydrogen in asymmetric synthesis. Examples of applied green chemistry are supercritical water oxidation, on water reactions, and dry media reactions. Bioengineering is also seen as a promising technique for achieving green chemistry goals. A number of important process chemicals can be synthesized in engineered organisms such as shikimate, a Tamiflu precursor which is fermented by Roche in bacteria.

A chemist discovered that dried and ground banana peels are cheaper, 20 times more effective, and safer than alternatives for cleaning up water that’s been contaminated with heavy metals.

Scientists at the Los Alamos National Laboratory have developed a process that supercritical carbon dioxide in one of the chip preparations, and it significantly reduces the quantities of chemicals, energy, and water needed to produce chips.
