Green chemistry is a tool that deals with risk reduction and pollution prevention by addressing the intrinsic hazards of the substances. Concepts like inherently safe design of reactions and substitution of hazardous chemicals or those that pose a high risk are involved in it. More attention is required in the whole manufacturing process and life cycle of both products and waste. Green chemistry is applicable to all aspects of the life cycle of the product. To achieve the goal for a sustainable future, chemistry must be integrated with other disciplines. In particular, it is imperative that chemists, biologists and engineers work together to develop new sustainable processes. Although industry is substantially progressing, and technology and tools required making chemical manufacturing more sustainable are available, but much more can be accomplished for environmental remediation.
