The directive principles of state policy guarantee that the state should guard and improve the environment and safeguard the forests and wildlife of the country. For protection more than hundred laws have been passed which deal with pollution after it is formed. Pollution prevention act 1990 is the first and only act that concentrated on pollution prevention rather than typical treatment and remediation. This act seeks to prevent pollution by encouraging companies to reduce the generation of pollutants through cost effective changes in manufacture, procedure and raw material use.
Green chemistry has come to the forefront of chemical community particularly under the current pressure to avoid environmental pollution. Green chemistry also known as sustainable or environmentally benign chemistry has already demonstrated how chemistry can protect human health and the environment in an economically beneficial manner. Instead of limiting risk by controlling our exposure to perilous chemicals, green chemistry attempts to reduce and preferentially eliminate the menace, thus negating the necessity to control exposure. Thus green chemistry includes modified engineering practices, bioremediation, eco-friendly reaction media and concept of atom economy leading to almost zero waste.
The major barrier is that proven green chemistry technologies are not as readily available as are more traditional alternatives. A concerted research drive by industry, government and academia is needed to develop a wide range of trustworthy nonthreatening methodologies that will be available when needed.
