MECHANICAL TREATMENT IN ENHANCED LANDFILL-MININ...

Enhanced Landfill Mining (ELFM) is considered a remediating strategy for old dumpsites and
landfills in an environmentally sound manner. However  due to differences in MSW definitions
and less strict regulations and controls in the past  hazardous impurities from household waste
and IW from different enterprises could have entered the MSW system  causing major research
challenges in landfill mining. Not only the uncertainty of whether hazardous materials are
present inside a landfill is a risk to ELFM  but also the material composition itself. Both
strongly influence the type of pretreatment needed  as well as the quality of the material to
recover. Even if there is a record of the type of materials buried inside a landfill  still
landfill technology has a direct impact on the composition of landfilled waste. This may imply
that some municipalities have a higher CDW rate in their MSW landfills than others. However 
the main reason why CDW ended in landfills is due to its large amounts  properties (bulky and
heavy)  and simply  because it was said to have no value.
