NOVELTY - The device has a household refuse reception part with a tub (1), a loading funnel (3) and a cone (4), where the part is fixed in a tube (6) at the tip of the cone. The tube constituting a household refuse methanation and transport part has a valve (5) placed at one end of the tube. Another end of the tube is closed by a valve (7), and a pump (11) creates a depression in the tube. A drain (10) has a valve (9) to evacuate liquids. The latter end is fixed in a case (8) forming the methanized refuse expulsion part and having a pump (12) to create a depression and a tube (14) with a valve (13).    USE - The device is useful in an urban community for composting household refuse or putrescible organic material (claimed). It can also be used for composting animal manure, residual sludge and fermentable organic material.    ADVANTAGE - The device permits the composting of household refuse to be repeated daily at the rate of the garbage collection, where the refuse piles up progressively inside the tube of the reception part. The refuse is maintained permanently isolated from air and the process of proliferation of the anaerobic bacteria starts, which causes the fermentation of the organic compounds contained in the refuse. The tube acts as a hermetically sealed enclosure in which the refuse finds a favorable medium for methanation. The tubular structure of the medium allows to convey the refuse from the collecting place to the methanized refuse expulsion part which must be located far from the urban zones. The device enables to connect several refuse reception parts to the tube so that several disseminated urban communities can be connected to the same device, thus having an increased capacity by the increase in the number of users of the device.
