The organic residue taken from the methanisation stage is sepd., e.g. in a centrifuge in which the residue is conc. and the liq. contained is reduced by 50-85%. The sepn. stage is followed by a second reactor, comprising a second methanisation stage, into which the conc. organic residue from the sepn. is fed. ADVANTAGE - Highly conc. residues and waste are broken down to a very small residue for disposal, which forms no gaseous or liq. emissions. Up to 90% of the organic dry matter is broken down. The energy in the substrate is utilised to an optimum degree.de608610620660patent1995-19507258
