Summary: | Landfills are complex systems which could potentially contaminate the
environment. It should be prevented by providing impermeability during the
landfill design. In that aim related regulations should be followed and
adequate materials that provide impermeability should be used. The first part
of the paper presents review of the current regulations, interpretations, and
recommendations from U.S., EU and Republic of Serbia. Knowing that the
Serbian regulation should fully follow related European Directive, in
analyses some inadequate formulations and terms were observed related to the
Directive Annex I, 3.2. Request of the Regulation that deals with the bottom
of the landfill leakage is formulated differently than in Directive as well.
Mentioned problems enable some design solutions which are not among the best
available techniques. In the second part the paper presents comparative
analysis of possible alternatives in impermeable layer design, both for the
bottom and landfill cover. Some materials like clay, CCL, GCL might not be
able to satisfy prescribed requirements. The longest lifetime and the lowest
coefficient of permeability, as well as excellent mechanical, chemical and
thermal stability, show the mixture of sand, bentonite and polymers (PEBSM).
