Mathias Janssen

Senior Researcher at Environmental Systems Analysis

Matty Janssen's research addresses life cycle assessment (LCA) during technology development, specifically its application to assess technology that is in its early stages of development. LCA can thus inform technology developers to achieve an environmentally benign design of a technology. His research focuses on method develpment for such prospective assessments. Application areas have been biorefinery processes and products (biofuels, bio-based chemicals and bio-based materials), and circular economy solutions (e.g. second use and material recycling of Li-ion batteries).

Furthermore, he is examiner of the Environmental Systems Analysis (VMI010) and Life Cycle Assessment (VTM081) courses at Chalmers.
