In my research I focus on developing approaches for prospective sustainability assessment of biobased chains, which are commonly at low maturity or so-called technological readiness level (TRL). The main challenges that my research focusses on are to deal with limited and uncertain data available for immature biobased technologies and to quantify the expected environmental, economic and social impacts and trade-offs between them. My research aims at developing a robust approach to quantify sustainability trade-offs based on uncertain and limited data. My team develops simulation models using approaches from Process Systems Engineering (PSE), Operations Research (OR) and sustainability assessment to quantify the expected performance and related system-wide sustainability impacts of low technological-readiness biobased systems. Close collaboration with experts within the disciplines primary production (‘feedstocks’) and conversion (‘biorefinery and processing’) is required to ensure validity of the developed mathematical models and resulting early sustainability assessment.
