Method and device for the progressive development of waste dumps with a view to recovering the biogas

摘要

Method and associated device making it possible to make use of the biogas generated by the waste stored in a dump. In the case of an evolutive dump, the level of the surface varies periodically as a result of more waste being brought in and the present invention enables the wells to be progressively adapted to the various levels by means of a simple operation, the well casing 1 and the perforated collection probe 17 being held in place. Application to the recovery of methane derived from the biogas in waste dumps made up partly of organic elements 3. <IMAGE>
