Green chemistry

Abstract

This chapter on green chemistry emphasises the role of inorganic chemistry in advancing environmentally sustainable industrial processes. It is framed by the 12 principles of green chemistry, proposed by Anastas and Warner, which focus on reducing waste, increasing energy efficiency, and minimising the use of hazardous substances. The chapter outlines how industries, particularly the chemical sector, have historically been viewed as polluting but are now transitioning towards greener technologies. These changes are often driven by legislation and economic incentives rather than purely altruistic motives. The principles guide the design of safer chemicals and processes, with catalysts playing a crucial role in improving efficiency and reducing by-products. The development of biodegradable materials and the use of renewable feedstocks are also central to green chemistry. Lastly, real-time monitoring of chemical processes is encouraged to prevent pollution, while accident prevention is emphasised as critical for safer chemical practices.
