Green chemical technologies have eliminated waste, improved safety, enhanced security, and saved industry money. This workshop will introduce the principles of green chemistry, provide industrial and academic examples of greener technologies, and highlight the economic benefits of adopting environmentally friendly processes. The chemical process industry aims particularly at energy, capital expenditure and variable feedstock cost savings due to fierce global competition and requirements for sustainable development. Increasingly novel processes are used in the industry to achieve these aims. They are used in: a) existing processes to renew parts; b) process re-designs based on existing feedstock's and catalysts; c) innovative processes (new feed stocks, new catalysts, new process routes, new multifunctional equipment).
