Materials for the energy transition: Importance of recycling

The energy transition aims, among other things, to reduce the impacts on climate change, and in particular CO 2 emissions linked very high consumption of fossil fuels (coal, oil, gas). solution lies firstly sobriety, secondly improving efficiency finally, development carbon-free energies with, particular, renewable (EnR). On this last point, deployment processes requires mobilization materials relatively large quantities due low concentration resource (Vidal, 2018). We highlight here necessary for implementation various production systems by focusing main which are concrete, steel, copper, aluminum, glass polymers. will only discuss these here. However, we must not forget so-called critical also used, albeit smaller quantities, but can pose a problem terms resources their scarcity (IEA 2021). Attention is paid recycling significantly changes point view. It shown interest of, course, maximizing recycling.
