Handbook of Green Chemistry and Technology
by James H. Clark, ‎Duncan J. Macquarrie
Sustainable development is now accepted as a necessary goal for achieving societal, economic and environmental objectives. Within this chemistry has a vital role to play.
The chemical industry is successful but traditionally success has come at a heavy cost to the environment. The challenge for chemists and others is to develop new products, processes and services that achieve societal, economic and environmental benefits.This requires an approach that reduces the materials and energy intensity of chemical processes and products; minimizes the dispersion of harmful chemicals in the environment; maximizes the use of renewable resources and extends the durability and recyclability of products in a way that increases industrial competitiveness as well as improve its tarnished image.The sustainable development of global society should not compromise the needs of future generations.It is complementary to green chemistry which seeks to make chemicals and chemical manufacturing environmentally benign and hence leaving the planet unharmed for our children. The concept of sustainability is discussed in Chapter 4 where the sustainable use of chemical feed stocks, water and energy are considered in turn. A sustainability scenario is also described.The chemical industry of the twenty-first century needs to fully embrace the principles of green chemistry through higher atom efficiency giving better utilization of raw materials, less waste, simpler and safer processes based on flexible smaller reactions, safer products and an increasing utilization of renewable feed stocks. These should be exciting rather than depressing times for chemistry and chemical technology; there are countless opportunities for innovation and the application of new cleaner technologies. The potential benefits of successfully ‘greening the chemical industry’ are enormous and of benefit to all society and future generations. |EBOOK DOWNLOAD| |Pages 540| |Size 7.2MB|
