Some novel aspects of green process engineering

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.
