Abstract

L'invention concerne un système multichambre (1) conçu pour générer un biogaz à partir d'un substrat fermentable. Le système selon l'invention présente une structure spécifique comprenant au moins deux chambres, de préférence trois chambres (2, 3, 4) permettant la mise en œuvre d'un procédé de génération de biogaz garantissant une génération de gaz en continu en cas d'approvisionnement discontinu en biomasse digestible. Le procédé pour générer un biogaz dans le système multichambre (1) prévoit en particulier un contenant de fermentation (3) prenant en compte plusieurs aspects pour une génération de biogaz efficace, en particulier le stockage temporaire du substrat digestible en cas d'approvisionnement irrégulier en biomasse nécessaire. De plus, la structure de l'ensemble du système multichambre (1) est conçue de manière à pouvoir être construite de manière compacte selon une configuration modulaire.
