\"Klybeck-Areal<\/a>
Le site de Klybeck, marqu\u00e9 par l'industrie chimique, doit devenir un nouveau quartier de B\u00e2le (source : Rhystadt)<\/figcaption><\/figure>\n

Rhystadt et Swiss Life, les deux propri\u00e9taires du site industriel de Klybeck \u00e0 B\u00e2le, ont lanc\u00e9 une offensive d'information concernant les sites contamin\u00e9s sur l'ancien site chimique. Dans le cadre de la pr\u00e9paration du projet indicatif, les r\u00e9sultats des analyses effectu\u00e9es dans les diff\u00e9rentes parties du site seront publi\u00e9s, ont annonc\u00e9 les investisseurs lors d'une conf\u00e9rence de presse. Ils souhaitent ainsi \"cr\u00e9er la base d'un dialogue objectif\". Par le pass\u00e9, la gestion des nuisances de l'ancien site chimique, qui doit devenir un nouveau quartier d'habitation et de travail, avait r\u00e9guli\u00e8rement suscit\u00e9 des critiques publiques.<\/p>\n

Selon Rhystadt et Swiss Life, on dispose d\u00e9sormais d'une image compl\u00e8te de la situation de pollution dans leurs parties du site, aussi bien dans le sous-sol que dans les b\u00e2timents. Dans le sol, il n'y a actuellement qu'un seul site pollu\u00e9 \u00e0 assainir. Il s'agit d'une pollution au chlorobenz\u00e8ne dans l'aire 3 de Swiss Life. Son assainissement est actuellement pr\u00e9par\u00e9 par l'ancien propri\u00e9taire BASF. La situation de pollution des b\u00e2timents est tr\u00e8s variable. Certains immeubles pourraient d\u00e9j\u00e0 \u00eatre r\u00e9utilis\u00e9s aujourd'hui. D'autres b\u00e2timents sont contamin\u00e9s par l'amiante. Mais dans l'ensemble, une grande partie du site est class\u00e9e par l'autorit\u00e9 d'ex\u00e9cution comme \"pollu\u00e9e et n\u00e9cessitant une surveillance\".<\/p>\n

200 rapports avant publication<\/h3>\n

Les propri\u00e9taires qualifient l'\u00e9limination des sites contamin\u00e9s de \"t\u00e2che importante, mais r\u00e9alisable\". Elles pr\u00e9parent actuellement le projet indicatif qui devrait \u00eatre achev\u00e9 \u00e0 l'\u00e9t\u00e9 2025. Dans ce cadre, la publication de r\u00e9sultats d'\u00e9tudes et de documentation est annonc\u00e9e, qu'il s'agisse de ceux dont disposaient les investisseurs lors de l'achat de leurs parts de terrain ou de rapports suppl\u00e9mentaires sur des proc\u00e9dures achev\u00e9es, que Rhystadt et Swiss Life ont command\u00e9s dans le cadre du projet de d\u00e9veloppement. Dans un premier temps, pr\u00e8s de 200 rapports seront accessibles sur les sites Internet des deux soci\u00e9t\u00e9s. En outre, les r\u00e9sultats du monitoring des eaux souterraines, pour lequel l'autorit\u00e9 a approuv\u00e9 un nouveau concept en 2024, seront probablement publi\u00e9s cette ann\u00e9e encore.<\/p>\n

Le site est pr\u00e9vu pour accueillir environ 10 000 habitants et de nombreux emplois, ce qui en fait l'un des plus grands projets de quartier de Suisse. Les deux propri\u00e9taires visent une certification de durabilit\u00e9 (SNBS, Standard pour la construction durable en Suisse) pour le nouveau quartier.
