Guillaume Majeau-Bettez

Guillaume Majeau-Bettez is an Associate Professor at Polytechnique Montréal, affiliated with the Department of Chemical Engineering. A leading expert in Industrial Ecology and Life Cycle Assessment, he contributes to the Research Chair on the Recovery of Residual Materials (CRVMR) and the NSERC Strategic Network on Green Surface Engineering (GreenSEAM).

• Education: B.Sc. in Environmental Chemistry (McGill), M.Sc. and Ph.D. in Industrial Ecology (NTNU).

His research focuses on environmental optimization of recycling loops, prospective analysis of technological transitions, and development of open-source LCA tools. Recent work includes modeling aluminum decarbonization pathways and assessing the environmental impacts of electric vehicles and surface engineering technologies.

Key publication trends show expertise in hybrid LCA methods, material flow analysis, and policy-informing frameworks for circular economies. His supervised students have produced theses on topics like thermal spray efficiency and tire recycling systems.

• Projects: $3.4M initiative to reduce greenhouse emissions (2024), $1M carbon neutrality funding (2023).
