A method of treating waste comprises forcing oxygen through the waste in a site at a first location at a first depth below the surface of the waste and extracting gas from a second location as a second depth. Oxygen is also forced through the waste at the first location at a third depth and is extracted from the second location at a fourth depth. An apparatus 50 for treating waste within a well is also disclosed, which comprises a hollow body 51 having a perforated or fluid permeable wall 54 and a conduit system 55 to supply or withdraw fluid to or from the interior of the body. A sealed region (550, Fig. 7B) is also included into which or from which fluid can be supplied or withdrawn. The sealed region is preferably defined by inflatable seals 57 which provide a tight seal between the body and the well wall. |
