Devenus objets de notre quotidien au m\u00eame titre que nos cl\u00e9s de voiture ou notre smartphone, les masques chirurgicaux sont des alli\u00e9s cruciaux dans la lutte contre le COVID-19. Pourtant, ils pr\u00e9sentent probl\u00e8me de taille\u00a0: pour \u00eatre efficace, ils doivent n\u00e9cessairement \u00eatre facilement rempla\u00e7ables. Or, dans notre soci\u00e9t\u00e9, cela veut n\u00e9cessairement dire qu\u2019ils sont la source d\u2019\u00e9norm\u00e9ment de gaspillage. On estime ainsi que 129\u00a0milliards de masques ont \u00e9t\u00e9 jet\u00e9s<\/strong> durant les premiers mois de la pand\u00e9mie. Beaucoup d\u2019entre eux finissent par polluer les oc\u00e9ans et m\u00eame l\u2019air lorsqu\u2019ils sont br\u00fbl\u00e9s.<\/p>\n

Aussi, des scientifiques de l\u2019universit\u00e9 MISIS ont souhait\u00e9 trouver une solution. Plut\u00f4t que de jeter les masques \u00e0 la poubelle, ils ont d\u00e9cid\u00e9 de les transformer en batterie.<\/strong> Ces derni\u00e8res font en effet l\u2019objet de nombreuses exp\u00e9rimentations, cherchant tour \u00e0 tour \u00e0 s\u2019adapter aux besoins actuels des appareils<\/a> et \u00e0 r\u00e9duire leur impact environnemental<\/a>. C\u2019est donc ce dernier domaine qui a int\u00e9ress\u00e9 l\u2019\u00e9quipe de MISIS, en mettant au point un proc\u00e9d\u00e9 capable de donner une nouvelle vie aux masques.<\/p>\n
