  • the invention relates to a method and system for treating a mixture of substances according to the preamble of claims 1 and 23.
  • Wash-out liquid can be washed out of the mixed substance.
  • a constant agitation and homogenization takes place by means of an agitator so that the organic substances can be broken down evenly.
  • This wash-out process results in a "hydrolysis", that is, the organic substances are liquefied by a biological digestion in the presence of air. In an aerobic process, the cells of the organic substances are therefore biologically disrupted, the washing liquid simultaneously serving as a means of transport and inoculant.
  • composting water is also added to a small extent.
