Biography
Guillaume Majeau-Bettez strives to better quantify the environmental consequences of our technology choices. His research pushes further the level of integration of complex-system analysis tools, in order to better inform environmental strategic decisions, especially those of the industrial and governmental partners of the International Life Cycle Chair (ILCC) and the Advanced Recycling and Material Recovery Chair (CRVMR).
Guillaume Majeau-Bettez is particularly interested in the environmental optimization of material recycling loops, in order to anticipate the challenges (accumulation of impurities, etc.) and the viable transition pathways toward a Circular Economy. His research also contributes significantly to the open life cycle assessment of Li-ion batteries and electric vehicles, as well as the optimization of their deployment as a climate change mitigation measure.
