Comme dans toute chose de la vie il suffit parfois de s’inspirer de ce que la nature fait de mieux, toutes les solutions \u00e0 nos probl\u00e8mes sont \u00e0 port\u00e9es de main … et il suffit parfois d’observer pour avoir la bonne id\u00e9e !<\/p>\n

C’est ainsi que les chercheurs de l’Institut de Technologie des Proc\u00e9d\u00e9s Chimiques de l’Environnement du Conseil National de Recherches Canada (ITPCE-CNRC) pensent avoir trouv\u00e9 la solution en s’inspirant du processus de digestion ana\u00e9robie des vaches.<\/p>\n

Ce ruminant poss\u00e8de dans son estomac des micro organismes qui peuvent purifier le m\u00e9thane et amener ainsi \u00e0 la production d’un m\u00e9thane quasi pur.<\/p>\n

En fin de cycle il ne reste alors que quelques traces de CO2 qui pourrait \u00eatre \u00e9limin\u00e9 gr\u00e2ce \u00e0 une membrane sp\u00e9cifique perm\u00e9able au CO2.<\/p>\n

Bien entendu on continuerait \u00e0 produire du CO2 mais le ratio lui est favorable sur sa contribution \u00e0 l’effet de serre.<\/p>\n
