(JP9294969-A)      Production of resource from organic waste comprises recovering methane gas from organic slurry by anaerobic digestion, converting fermented slurry into carbon slurry by hydrothermal reaction and solid-liquid separating to recover condensed carbon slurry.    USE -   Organic waste is reused as a resource.    ADVANTAGE -   The organic waste can be treated without increasing moisture content and can prevent corruption during storage and the aqueous phase after hydrothermal reaction can be effectively treated.    (US6143176-A)      Organic waste (1 in Fig. 1) is converted into valuable resources by: (a) retaining a slurry of the waste in an anaerobic digester (4) to generate a methane-containing gas (6) and a fermentation slurry (7); (b) subjecting this slurry to hydrothermal reaction 11) to generate a carbon slurry (13); and (c) optionally separating an aqueous phase from the latter, to yield a concentrated carbon slurry (17) having high heating value.    USE -   The waste may be municipal or industrial waste, night soil or sewage sludge.    ADVANTAGE -   The method provides effective hydrothermal treatment of a slurry of low water content, which prevents the slurry purifying during the process; it and permits effective treatment of the aqueous phase after the hydrothermal treatment.
