<p>The present invention relates to a process and plant for the anaerobic fermentation of organic material originating from municipal waste. This plant comprises: a mixer (5), in which the organic material is diluted with a diluant originating from a pipe (6), and two fermenters (9, 10) connected to the mixer (5), the exit (14) of the first fermenter (9) being connected to the second fermenter (10) via a pump (12) and the exit (16) of the second fermenter (10) being connected to the upstream side of the first fermenter (9) via a pump (11), whereas part of the material exiting from the second fermenter (10) passes into a dehydrating means (18) which produces liquor which is recycled, via the pipe (6), to the mixer (5) in order to dilute therein the fresh organic material which enters therein; and a loop (22, 23) for controlling the viscosity as well as a loop (24, 25, 26) for controlling the temperature of the material passing into the fermenters. This process and this plant apply in particular to the fermentation of household (domestic) waste. <IMAGE></p> |
