Les 46 % restants, qui correspondent aux produits organiques impropres \u00e0 la consommation, doivent obligatoirement \u00eatre d\u00e9truits. C\u2019est pourquoi, pour limiter l\u2019impact \u00e9cologique des d\u00e9chets alimentaires, la cuisine centrale a \u00e9tabli en 2021 un partenariat avec la Baie des Champs. Il s\u2019agit d\u2019une exploitation en agriculture raisonn\u00e9e aux activit\u00e9s vari\u00e9es&nbsp;: \u00e9levage de cochons, cultures, huilerie, maraichage bio. Cette entreprise, situ\u00e9e \u00e0 S\u00e8vres-Anxaumont, dispose \u00e9galement d\u2019une plateforme de compostage et d\u2019une unit\u00e9 de m\u00e9thanisation qui produit de l\u2019\u00e9lectricit\u00e9 renouvelable. Elle collecte et recycle ainsi les d\u00e9chets verts ainsi que les biod\u00e9chets des habitants des communes voisines et des grandes entreprises alentours. Jusqu\u2019\u00e0 tr\u00e8s r\u00e9cemment, la cuisine centrale, ainsi que la restauration du situ\u00e9 au 11<sup>e<\/sup> \u00e9tage de Jean-Bernard, y transf\u00e9raient ses biod\u00e9chets pour une transformation en m\u00e9thane. Ce processus, cr\u00e9ant du biogaz, permet la production d\u2019\u00e9lectricit\u00e9 et de chauffage qui rendent la Baie des champs partiellement autonome.<\/p>\n<p>&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-media-text alignwide is-stacked-on-mobile\" style=\"grid-template-columns:35% auto\"><figure class=\"wp-block-media-text__media\"><img decoding=\"async\" width=\"600\" height=\"900\" src=\"https:\/\/www.chu-poitiers.fr\/wp-content\/uploads\/2023\/01\/Methaniseurs.jpg\" alt=\"\" class=\"wp-image-1101017 size-full\"\/><\/figure><div class=\"wp-block-media-text__content\">\n<p class=\"wp-block-paragraph\">Pr\u00e8s de 4 tonnes de biod\u00e9chets sont \u00e9t\u00e9 envoy\u00e9es en m\u00e9thanisation tous les 6 mois pour \u00eatre transform\u00e9es en quelques 560m<sup>3<\/sup> de biogaz, de quoi fournir 1\u00a0280 KWh \u00e0 la structure. Depuis peu, la valorisation des biod\u00e9chets des cuisines du CHU passe dans une autre fili\u00e8re de traitement. En effet, trois d\u00e9shydrateurs ont \u00e9t\u00e9 acquis pour transformer les biod\u00e9chets en compost. Deux d\u2019entre eux ont \u00e9t\u00e9 install\u00e9s \u00e0 la cuisine centrale de Beaub\u00e2ton, l\u2019un au niveau de la cantine du personnel, l\u2019autre au niveau de la production. Le troisi\u00e8me se trouve au 11<sup>e<\/sup> \u00e9tage de Jean-Bernard. Ces \u00e9quipements, pas beaucoup plus grand qu\u2019un lave-linge, permettent de traiter directement sur place 30 kg de biod\u00e9chets \u00e0 la fois. Faciles \u00e0 utiliser, ils transforment les biod\u00e9chets en compost, r\u00e9duisant leur volume d\u2019environ 75% sans d\u00e9gager de mauvaises odeurs. Ce sont pr\u00e8s de 28 kg de biod\u00e9chets qui sont ainsi trait\u00e9s chaque jour \u00e0 la cuisine centrale et au 11<sup>e<\/sup> \u00e9tage. Le compost produit est ensuite transf\u00e9r\u00e9 \u00e0 la Baie des champs tout comme le sont les d\u00e9chets verts produits sur le site de la Mil\u00e9trie. La nouvelle gestion des biod\u00e9chets se r\u00e9v\u00e8le d\u2019ores et d\u00e9j\u00e0 plus facile pour les professionnels de la restauration puisqu\u2019elle ne n\u00e9cessite pas de grands espaces de stockage, n\u2019entraine pas de mauvaise odeur, et les circuits de transport sont ainsi simplifi\u00e9s.<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>La cuisine centrale du CHU de Poitiers poursuit son engagement dans une d\u00e9marche \u00e9co-responsable pour une cuisine saine, de qualit\u00e9 et respectueuse\u2026","protected":false},"author":12,"featured_media":1100931,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[96],"tags":[],"class_list":["post-1100851","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-non-classifiee"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Cuisine centrale : valoriser les biod\u00e9chets - Site du CHU de Poitiers<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.chu-poitiers.fr\/cuisine-centrale-valoriser-les-biodechets\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Cuisine centrale : valoriser les biod\u00e9chets - Site du CHU de Poitiers\" \/>\n<meta property=\"og:description\" content=\"La cuisine centrale du CHU de Poitiers poursuit son engagement dans une d\u00e9marche \u00e9co-responsable pour une cuisine saine, de qualit\u00e9 et respectueuse de l\u2019environnement.
