Two-stage anaerobic digestion of the organic fraction of solid urban wastes and wastes similar to urban wastes originating from differentiated collection

摘要

Process for the two-stage anaerobic degradation of the organic fraction of wastes. A process which is designed to produce methane based on a first countercurrent plug-flow stage which offers high control of the acid producing stage and the production of solid fermentation residue is provided as an example.
