Sustainable Green Chemical Technology for Developments in Process Industries

The environmental and climate issues facing across the world are widely recognized as serious problems. Therefore, green technologies and ecological sustainable development is need of the hour as the quality of life is worsening. We have had major progress in technology causing depletion of natural life sustaining resources, especially clean air and water. These problems are causing considerable environmental, economic and social impairment on a worldwide scale. Sustainable development implies that renewable resources should be used wherever possible and that non-renewable resources should be husbanded (e.g., reduced and recycled) to extend their viability for generations to come. The paper will present the trend towards sustainability and green technologies in the chemical process industry (CPI). A broad review of state-of-the-art green technologies in the understanding and application of sustainability with few case studies highlighting the economic benefits of adopting green processes from a chemical engineering viewpoint is addressed. Green technologies increasingly uses renewable resources; reduce wastes, pollutants, emissions; recover, reuse and recycle; reduce the pressure on natural resources and restore the balance of the eco-system and biosphere and ultimately help in providing "ecologically sustainable development". These technologies are, therefore, viable, cost-effective, environmentally advanced and most appropriate to the climatic, economical, geographical, ecological and social conditions of the country. This aim can only be achieved by developing new environmentally friendly, safe and non-toxic materials and their based innovative technologies. Therefore CPI must promote sustainable development by investing in green technologies and ensure increased adherence to safety, health and environmental standards.
