To Study the Current Status, and Future Challenges of Green Chemistry

Abstract

Green chemistry emerged from 1990s, in the increasing attention to problems of chemical pollution and resource depletion. The development of green chemistry was linked to a shift in environmental problem-solving strategies i.e. a movement from command and control regulation and mandated reduction of industrial emissions by the active prevention of pollution through the innovative design of production technologies themselves. The concepts now recognized as green chemistry and "sustainable" chemistry. Attempts are being made not only to quantify the greenness of a chemical process but also to factor in other variables such as chemical yield, the price of reaction components, safety in handling chemicals, hardware demands, energy profile and ease of product workup and purification. Green chemistry is increasingly seen as a powerful tool that researchers must use to evaluate the environmental impact of nanotechnology. As nanomaterials are developed, the environmental and human health impacts of both the products themselves and the processes to make them to ensure their long-term economic viability. Green solvents are generally derived from renewable resources and biodegrade often a naturally occurring product. Green technology (greentech) is the application of one or more of environmental science, green chemistry, environmental monitoring and electronic devices to monitor, model and conserve the natural environment and resources, and to curb the negative impacts of human involvement. 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. Over the course of the past decade, green chemistry has demonstrated how fundamental scientific methodologies can protect human health and the environment in an economically beneficial manner.
