Liners and drains
Every section of the Environmental Centre comprises an underlying liner that collects leachate. The liner system is comprised of a moraine clay layer, a polymer liner and a drainage and protective layer.
Pre-treatment of leachate
The collected leachate from the landfill is transferred to the Environmental Centre's pre-treatment plant. The leachate is pre-treated here so that it corresponds to ordinary urban sewage and is then led to the grid for further treatment at one of the waste water treatment plants.
