DescriptionDeposits of waste were already in existence at the location of the Einöd landfill site when regulated landfill site operation started in 1982. These waste deposits had to be taken into consideration when the landfill site was upgraded. Before the base seal for fill section II was made an area of tar deposits (liquid to soft waste from the waste oil treatment plant with very high PCB and PAC contents) was decontaminated by removal, stabilisation and immobilisation of the pollutants.
In order to segregate the different waste substances a combined intermediate and basic seal was constructed with a separate system for leachate collection and drainage. For this a structure had to be built consisting of an entrance building with a plant room and a unit for the separation of polluted and non-polluted materials, a connecting gallery (created using pipe driving DN 2400) and the shaft structure for the purification and inspection of the leachate drainage. Here, the leachate from the old deposits was collected and drained off separately from the leachate from the areas where the site was expanded.
