  • RECOVERY OF METHANE FROM SOLID DIGESTATES
    Publication number: 20210363550
    Abstract: Process for producing biogas from a digestate obtained from a digester, said process comprising a step of recovering the digestate at the outlet of a digester, a post-digester or a storage tank; a step of separating the digestate into a solid digestate and a liquid digestate; a step of introducing the solid digestate into at least one dosed tank; a step of anaerobic digestion in the tank with neither heating nor mixing; and a step of recovering the biogas at the tank outlet.
