GREEN CHEMISTRY DEFINITION Green Chemistry is the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in , – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow - id: 3b74c3-YTQ1M
The past twenty or so years have seen the rise of the so-called ‘green’ chemistry, a movement whose adherents want the discipline to adopt a set of twelve principles (Anastas and Warner 1998) in the belief that, through their application, clean chemical technology will resultThe original principles (reproduced in Table 1) encapsulate several worthy—if broadly stated—objectives .
The Need for Green Chemistry There is increasing pressure from both society and governments for chemistry-based industries to become more sustainable through development of eco-friendly products and processes that both reduce waste and prevent toxic substances from entering the environment
