| Résumé : |
The uses of hazardous and toxic solvents in paint laboratories and in paint industries are considered a very crucial problem for health and safety of workers and environment. Majority of solvents are organic chemicals with harmful and toxic properties, large waste part of by-products of the chemical industry causing environmental and health problems, but its uses are important. So, it is better to prevent voc and minimize waste than to face problems and treat or clean up waste after it has been created, therefore, it is widely acknowledged that there is a growing need for more environmentally acceptable processes in the chemical industry.
The trend towards what has become known as Green Chemistry' or Sustainable Technology', necessitates a paradigm shift from traditional concepts of process efficiency, that focus largely on chemical yield, that assigns economic value to eliminating waste at source and avoiding the use of toxic and/or hazardous substances.
The review paper is mainly based on the Green chemistry, which places both company profitability and ecological health at the heart of innovative product design and manufacturing. It uses the creativity of nature's biological processes to create molecules, materials and processes that are safe and high-performing. |
