En 2019, 86% de la demande a \u00e9t\u00e9 satisfaite par les cimenteries suisses. Les mati\u00e8res premi\u00e8res chaux et marnes, utilis\u00e9es dans l&rsquo;industrie du ciment, sont disponibles en Suisse.<\/p>\n<p class=\"bodytext\"> Cependant, un <a href=\"https:\/\/www.admin.ch\/gov\/de\/start\/dokumentation\/medienmitteilungen.msg-id-81701.html\" target=\"_blank\" rel=\"noopener\">rapport<\/a> dont le Conseil f\u00e9d\u00e9ral a pris note suppose que la production de ciment en Suisse devrait baisser dans les ann\u00e9es \u00e0 venir. La raison en est la r\u00e9sistance \u00e0 l&rsquo;expansion ou \u00e0 la r\u00e9ouverture des carri\u00e8res. Si les projets d&rsquo;expansion mini\u00e8re demand\u00e9s pour les mati\u00e8res premi\u00e8res, chaux et marnes, d\u00e9finis dans les plans de structure cantonaux ne sont pas approuv\u00e9s, l&rsquo;offre de la Suisse en ciment domestique tombera \u00e0 64% d&rsquo;ici 2024, selon le rapport.<\/p>\n<p class=\"bodytext\"> Le rapport propose donc que les gisements de mati\u00e8res premi\u00e8res qui sont importants pour la production de ciment soient \u00e9galement envisag\u00e9s du point de vue de l&rsquo;approvisionnement national. Actuellement, le pouvoir d&rsquo;approbation des projets de d\u00e9mant\u00e8lement appartient aux communes et aux cantons. L&rsquo;objectif est de cr\u00e9er une vue d&rsquo;ensemble nationale des gisements de mati\u00e8res premi\u00e8res et de les \u00e9valuer d&rsquo;un \u00abpoint de vue g\u00e9ologique des mati\u00e8res premi\u00e8res\u00bb. Cela donnerait aux autorit\u00e9s et aux producteurs de mati\u00e8res premi\u00e8res une base pour la planification des projets miniers.<\/p>\n<p class=\"bodytext\"> Dans sa communication, le Conseil f\u00e9d\u00e9ral souligne \u00e9galement que l&rsquo;Office f\u00e9d\u00e9ral de l&rsquo;environnement ( <a href=\"https:\/\/www.bafu.admin.ch\/bafu\/de\/home.html\" target=\"_blank\" rel=\"noopener\">OFEV<\/a> ) travaille actuellement avec la recherche et l&rsquo;industrie pour trouver de nouvelles solutions pour remplacer les mati\u00e8res premi\u00e8res primaires chaux et marnes par des mati\u00e8res premi\u00e8res secondaires. Jusqu&rsquo;\u00e0 pr\u00e9sent, cependant, cela n&rsquo;a \u00e9t\u00e9 possible que dans une mesure tr\u00e8s limit\u00e9e. Cependant, des technologies sont \u00e9galement en phase de d\u00e9veloppement qui remplaceront le ciment dans le b\u00e9ton ou m\u00eame conduiront \u00e0 un b\u00e9ton sans ciment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Die Produktion von Zement in der Schweiz k\u00f6nnte ab 2024 abnehmen, wie ein Bericht des Bundes zeigt.
