METHOD FOR UPGRADING WASTE

The invention relates to a method for upgrading substrates, comprising: A. introducing (110) volumes of substrates (10) into strainers (20), B. humidifying (120) a volume in order to hydrolyse the organic constituents thereof, C. injecting (140) the leachate from the humidified volume into an anaero...

Beschreibung
Zusammenfassung:	The invention relates to a method for upgrading substrates, comprising: A. introducing (110) volumes of substrates (10) into strainers (20), B. humidifying (120) a volume in order to hydrolyse the organic constituents thereof, C. injecting (140) the leachate from the humidified volume into an anaerobic digester (30), D. sending a portion of the liquid from the digester back into a strainer for step B, and E. repeating steps B to D. The method is characterised in that all of the leachate is injected directly into the digester, and in that, beyond a threshold time value, the method further comprises: F. performing aerobic fermentation (181) of the volume of substrates in the strainer; and G. performing aerobic maturation (182) of the volume of substrates in another aerobic location (50) in order to obtain a stabilised compost, lower than a maximum threshold value and/or higher than a minimum threshold value.
