It now reinjects part of it into the public network and to supply its collection trucks. So-called “ultimate” non-hazardous waste, ie that cannot be recycled or recovered elsewhere, is brought to the Ecosite disposal center in Vert-le-Grand / Echarcon. Confined and following a natural process, the waste decomposes and produces gas. After purification, a gas rich in methane is obtained, this is biogas. To recover it, a network of wells and pipes crisscrosses the entire locker. At Semardel, the lockers are managed in “bio-reactor” mode, a process that accelerates the waste degradation process and therefore optimizes biogas production. Lockers are closed after 18 months, containment is increased for greater soil protection. The captured gases are used as heat, electricity: The heat is used to heat the Semardel facilities and to treat the leachate . Liquid composed of the wet part of the stored waste and the runoff of rainwater. Electricity is injected into the electricity network for residents and businesses . Thus, 20,500 MegaWattHours are produced per year, which represents the annual consumption of 4,360 households. Innovation 2018, Semardel injecte désormais le biogaz dans le réseau de GRDF. Pour garantir aux fournisseurs d’énergie et aux consommateurs la provenance du gaz, Semardel émet des garanties d’origine. Le biogaz est épuré puis injecté dans le réseau de GRDF qui en contrôle la qualité et la quantité. Le biogaz devient alors du biométhane, disponible à la consommation du grand public au travers des offres des fournisseurs d’énergie. Semardel produit ainsi 5 500 MW/h par an de biométhane issu de la valorisation des déchets. Découvrez la valorisation du biogaz par SEMARDEL en vidéo : Semardel est elle-même consommatrice de son biogaz comme carburant pour ses camions roulant au Gaz Naturel pour Véhicules et dispose de sa propre station-service.
