Prof. dr. ir. Steven De Meester is assistant professor within the Department of Industrial Biological Sciences of the Faculty of Bioscience Engineering of Ghent University. His educational tasks involve courses such as waste treatment, environmental management and chemical engineering. With a background on chemical engineering and sustainability assessment his research topic is the sustainable design of chemical production chains with a focus on purification of components out of complex streams such as waste biomass and waste plastics. More concretely, the complex resource stream is analysed and then linked to an application after which a purification chain ‘fit-for-purpose’ is developed and optimized towards economic and environmental performance. For this purpose, unit operations such as (different types of) distillation, adsorption, extraction, selective flotation, etc. are used. Based on lab experiments and models (e.g. in ASPEN), the process chains are designed up to pilot scale. Prof. De Meester has extensive experience in working in different types of multidisciplinary projects, preferably in combination with industry.
