Abstract

In a method of continuously composting material capable of being composted by the action of aerobic microorganisms in a reactor, the material is caused to pass through the reactor as a single mass from the top thereof to the bottom thereof from an upper level in said reactor, and in which oxygen-containing gas required for the aerobic decomposition of the compostable material is passed through said single mass in contact therewith. The waste gas from the composting process is removed from the reactor by suction through pipes which extend down into the mass to be composted from the upper level thereof, with the openings of said pipes lying on a level located beneath said upper level in said reactor. A pressure is maintained in said pipes of such magnitude as to cause oxygen-containing gas to pass from said upper level of the reactor through the layer of compostable material extending down to the openings of said tubes, said addition of oxygen-containing gas to the compostable material being intended to start the decomposition process.
