Guillaume Majeau-Bettez is a Researcher within the two research chairs associated with the CIRAIG, the International Life Cycle Chair (ILCC) and the Research Chair for Advanced Waste Recovery (RCAWR). He is also Adjunct Associate Professor at the Norwegian University of Science and Technology (NTNU).

His research aims to better capture the complex causal chains that link consumption activities and technology choices to environmental emissions and resource extraction. To this end, he focusses on the coherent integration of multiple databases, analysis methods and tools; notably combining system descriptions from life cycle assessments (LCA), material flow analyses (MFA), economic and environmentally-extended input-output (EEIO) models, along with detailed parametrized engineering process models and optimization algorithms. He aims to go beyond mere “hybrid LCA”, and bring about a convergence of industrial ecology analysis perspectives, to address complex material-economic issues of downcycling, rebound effects, and circular economy.

After completing an Honours in Chemistry and Environmental chemistry at McGill University (Canada), Guillaume has obtained his Masters of Science and his Ph.D. in Industrial Ecology, at the Norwegian University of Science and Technology. During these studies, and his subsequent postdoctoral fellowship, he has specialized in the treatment of multifunctionality, coproduction and recycling in LCA and EEIO, and its implications for the hybrid analysis of circular economy scenarios.

Guillaume also pursues research on the sustainability of Li-ion batteries, electric vehicles, and transition scenarios toward electro-mobility. This line of research has lead him to develop methods to screen novel materials and technology candidates to anticipate early on potential environmental pitfalls. He is continuing this research to help orient material developments within the Green Surface Engineering for Advanced Manufacturing (Green-SEAM) NSERC Strategic Network. Guillaume is also associate editor at the Journal of Industrial Ecology, where he oversees steps for achieving greater data openness and transparency within our research field.
