To mitigate climate change impacts, highly efficient multi-faceted multi-product biorefinery systems must be developed to replace and dominate over fossil-based systems. In this context waste/biomass based integrated biorefinery systems are promising but currently at a nascent stage. There is an unmet need to bring together the critical areas of process integration and life cycle sustainability assessment with techno-economic, social, and environmental aspects, for estimating the overall sustainability of these biorefineries.

This project will focus on developing a multi-objective sustainability led optimization-based decision support tool towards exploring the potential of waste/biomass based biorefinery systems.

There will be opportunities to collaborate with world-class researchers at other leading academic institutions.

We are seeking enthusiastic and motivated applicants with an interest in sustainability and circular economy. Background knowledge of LCA/TEA is desirable.

The successful candidate will be supervised by Dr. Siddharth Gadkari and will be based at the Department of Chemical and Process Engineering. The department has a long history of excellence in sustainability research.
