Une technique in\u00e9dite de d\u00e9pollution des sols vient d\u2019\u00eatre lanc\u00e9e au c\u0153ur d\u2019une commune de l\u2019Oise.<\/h2>\n

On connaissait d\u00e9j\u00e0 toute l\u2019importance des plantes pour conserver un air de bonne qualit\u00e9, mais elles sont \u00e9galement tr\u00e8s dou\u00e9es pour assainir les sols. Les recherches en phytotechnologie ont montr\u00e9 que certaines esp\u00e8ces v\u00e9g\u00e9tales pouvaient aider \u00e0 d\u00e9barrasser les terrains de polluants tels que les m\u00e9taux utilis\u00e9s dans la plupart des industries.\u00a0<btn_noimpr>
\nC\u2019est tout l\u2019enjeu de l\u2019exp\u00e9rimentation qui a d\u00e9but\u00e9 \u00e0 Montataire, dans l\u2019Oise, au rond-point des Forges. Profitant de la r\u00e9novation de ce\u00a0carrefour<\/a>\u00a0situ\u00e9 au c\u0153ur d\u2019un quartier qui accueillait autrefois de nombreuses industries, la communaut\u00e9 de l\u2019agglom\u00e9ration creilloise et l\u2019Ineris (Institut national de l\u2019environnement industriel et des risques) ont lanc\u00e9 ensemble une exp\u00e9rience in\u00e9dite en\u00a0France<\/a>.
\n\u00ab Pendant quatre ans, nous allons tester deux techniques sur deux parcelles distinctes, explique Rodolphe Gaucher, responsable de l\u2019unit\u00e9 technologies et proc\u00e9d\u00e9s propres et durables de l\u2019Ineris. Sur 300 m2, sur une voie nouvelle, de la phytostabilisation, \u00e0 savoir des plantes capables de contenir et fixer les polluants dans le sol. Et sur 500 m2 au niveau du rond-point, de la phytoextraction, des esp\u00e8ces pouvant absorber les polluants dans leur feuillage. \u00bb
\nUne solution peu co\u00fbteuse<\/strong>
\nLa phytostabilisation a d\u00e9j\u00e0 \u00e9t\u00e9 test\u00e9e avec succ\u00e8s par l\u2019Ineris. C\u2019est surtout le volet extraction, test\u00e9 en conditions r\u00e9elles en pleine ville, qui int\u00e9resse les chercheurs. Pour l\u2019instant, seuls des saules des vanniers ont \u00e9t\u00e9 plant\u00e9s sur la parcelle. Ils seront bient\u00f4t rejoints par l\u2019arabette de Haller, petite plante sauvage hyperaccumulatrice de m\u00e9taux, sur laquelle l\u2019Ineris travaille depuis plusieurs ann\u00e9es et fonde de grands espoirs.
\n\u00ab Le probl\u00e8me de la phytoextraction, c\u2019est qu\u2019il faut compter en dizaine d\u2019ann\u00e9es avant de pouvoir parler de d\u00e9pollution, conc\u00e8de Rodolphe Gaucher. Mais c\u2019est une solution qui para\u00eet tr\u00e8s int\u00e9ressante en milieu urbain, o\u00f9 il n\u2019est pas toujours \u00e9vident de lancer de vastes travaux de d\u00e9pollution des terres. \u00bb
\nLe proc\u00e9d\u00e9 est bien s\u00fbr enti\u00e8rement naturel et la question du devenir des plantes remplies de m\u00e9taux tels que le zinc ou le cadmium, pr\u00e9sents dans le sol de Montataire, a \u00e9galement \u00e9t\u00e9 envisag\u00e9e. Compostage, m\u00e9thanisation ou combustion de la biomasse pour produire de l\u2019\u00e9nergie sont quelques-unes des possibilit\u00e9s de transformation de ces plantes, une fois accomplie leur mission d\u2019absorption des polluants.
\nPeu co\u00fbteuse, simple \u00e0 mettre en place, la\u00a0gestion<\/a>\u00a0des sols pollu\u00e9s par les plantes devrait avoir un bel avenir dans un pays comme la France o\u00f9 le minist\u00e8re de l\u2019Ecologie recensait 4100 sites pollu\u00e9s en 2012, auxquels s\u2019ajoutent plus de 250000 lieux ayant accueilli une activit\u00e9 industrielle, avec donc de possibles restes de polluants dans le sous-sol.
\nLes m\u00e9thodes classiques de d\u00e9pollution des terres co\u00fbtent cher : pas moins de 470 M\u20ac ont \u00e9t\u00e9 d\u00e9pens\u00e9s, en 2010 en France pour des op\u00e9rations de r\u00e9habilitation des sols. Plus douce avec les sols et l\u2019environnement, la phytotechnologie devrait \u00e9galement l\u2019\u00eatre avec le porte-monnaie des collectivit\u00e9s locales \u00e0 la recherche de solutions pour assainir leurs sous-sols.
