Integrated System for Sustainable Process Design Selection
Dr Tan , Jully Senior Lecturer PhD , CEng , MIChemE |
Increased environmental awareness has led to greater interest in the adoption of sustainable technologies . Optimization of sustainable process plant configurations requires the use of systematic assessment methods based on the usage of natural resources , release of pollutants and generation of environmental impact . Identification and selection of appropriate measures should also take into account factors such as cost-effectiveness , scalability , |
and investment techno-economic risk . Life cycle assessment as input for strategic decisionmaking enables the comparison of different technologies , which will then facilitate the selection of the most promising ones . Through an integrated analytic hierarchy process-life cycle assessment , the most sustainable process design or technology can be determined systematically . |

Photocatalysis has seen growing research interest in the past few years , not only in reactions involving small molecules such as CO2 ( reduction to solar fuels ), H2O ( water splitting ) and N2 ( fixation to ammonia ), but also in the synthesis of valuable fine chemicals . Though developing rapidly , the state-ofthe-art process remains , for now , a visionary technology . Its largescale application still requires intensified research in the areas of photocatalyst materials discovery and innovative photoreactor designs . With the end goal of industrializing photocatalytic systems , our research project therefore focuses on the smart engineering and rational design of various advanced nanomaterials
Example of process simulation diagram to assess the input-output of material and energy , and to evaluate environmental impacts of the process design
( e . g ., graphene , carbon nanotubes , g-C3N4 , quantum dots ) with tunable structural , electronic and optical properties . Apart from materials design , our research also targets at elucidating the fundamental mechanisms underlying high efficiency for the utilisation of solar energy . In summary , our research will provide new horizons to materials science , and could serve as a powerful means of addressing climate change and the high global energy demand .
