Municipal solid waste entombed in landfills will produce pollution in the form of landfill gas and leachate when the barriers fail in the long term. Bioreactor landfills are an alternative solution to avoid such negative impacts and to achieve a more stable residue, the so-called final storage quality (fsq) of residues. However, until now the main technical problem faced by landfill operators in bioreactor landfill operation is homogenous liquid distribution within the waste mass.The main objective of this thesis was to achieve a fsq status of waste, through laboratory and pilot-scale experiments, that complies with the waste acceptance criteria (wac) of the european landfill directive for inert waste. This thesis focused on the interaction and modification of the factors controlling the waste stabilisation process in a bioreactor landfill. The results revealed that within a year of operation biological stabilisation can be achieved, but not fsq status. However, residues were close to comply with such stringent criteria.
