Some novel aspects of green process engineering


London South Bank University, Department of Applied Sciences, Faculty of Engineering Science and the Built Environment, London, United Kingdom


Green process engineering (GPE) is an approach to make a hazardous and wasteful process more sustainable. The implementation of a wide range of innovative and effective green process technologies over the years has led to more environmentally friendly approaches that have resulted in greater pollution prevention via waste reduction and efficiency maximisation. This paper highlights some novel applications of green process engineering, particularly in the areas of supercritical carbon dioxide and catalytic processes, including the guidelines utilised in designing a green process, following twelve principles of green engineering.


One of the missions of modern green engineering community is to design and develop sustainable and economically proficient processes whilst giving adequate protection to the environment. Green process engineering (GPE) is defined as, “the design, commercialization, and use of processes and products, which are feasible and economical while minimizing (a) generation of pollution at the source and (b) risk to human health and the environment. Green engineering embraces the concept that decisions to protect human health and the environment can have the greatest impact and cost effectiveness when applied early to the design and development phase of a process or product” (1). In the UK, the first systematic attempts to control the polluting effects of
