Brique, b\u00e9ton, ciment et acier sont les principaux mat\u00e9riaux de construction en Suisse. Leur production est toutefois tr\u00e8s \u00e9nergivore. Le choix des bons mat\u00e9riaux est donc essentiel pour une construction durable. Les ressources locales, comme le bois et la pierre, poss\u00e8dent des propri\u00e9t\u00e9s diff\u00e9rentes mais compl\u00e9mentaires, offrant ainsi de nombreux avantages lorsqu\u2019elles sont combin\u00e9es.<\/h5>\n

Le b\u00e9ton se distingue par sa haute r\u00e9sistance \u00e0 la compression, sa durabilit\u00e9 et sa capacit\u00e9 \u00e0 \u00eatre recycl\u00e9, tandis que le bois s\u00e9duit par sa l\u00e9g\u00e8ret\u00e9, sa grande r\u00e9sistance \u00e0 la traction et sa capacit\u00e9 de stockage du CO2. En combinant ces mat\u00e9riaux de mani\u00e8re cibl\u00e9e, il est possible d\u2019optimiser la structure et de r\u00e9duire la consommation de mat\u00e9riaux \u2013 une avanc\u00e9e essentielle vers une construction plus respectueuse des ressources.<\/p>\n

Un exemple de combinaison de ces deux ressources en tant que mat\u00e9riaux de construction est
\n\u00ab KLARK \u00bb<\/span><\/a>. Ce b\u00e9ton bas carbone innovant int\u00e8gre du carbone biog\u00e9nique dans sa composition. Ce carbone est obtenu par pyrolyse, un proc\u00e9d\u00e9 qui transforme les r\u00e9sidus de bois non trait\u00e9 issus de la foresterie locale en biochar. Ce processus permet de fixer jusqu’\u00e0 60 % du dioxyde de carbone contenu, emp\u00eachant ainsi son rejet dans l\u2019atmosph\u00e8re par d\u00e9composition ou combustion.
\nTandis que le b\u00e9ton assure une grande stabilit\u00e9, le carbone contenu dans KLARK stocke durablement le CO2. Gr\u00e2ce \u00e0 la capacit\u00e9 de captation du biochar, le b\u00e9ton bas carbone KLARK est neutre en CO2 \u2013 voire n\u00e9gatif en CO2 selon sa composition.<\/p>\n

La Tour Blanche de Mulegns est la plus haute tour imprim\u00e9e en 3D au monde. Avec ce projet, la fondation Origen, l\u2019ETH Zurich, le groupe Uffer et Zindel United explorent de nouvelles approches de la construction et apportent ainsi des impulsions novatrices qui orientent le secteur du b\u00e2timent vers une modernit\u00e9 plus durable. \u00a9 ETH \u2013 DBT | Prof. Benjamin Dillenburger<\/p>\n
