The landfill is located about one kilometer south of Hoheneggelsen on the Hildesheim – Braunschweig railway line . There used to be a brickworks on the site, which extracted the clay required for brick production on site. What remained was open clay pits that were used to deposit waste.
The landfill consists of 21 up to 30 meter deep polders located within 300 meter thick claystone layers of the Lower Cretaceous . The polders were filled up to three meters below the surface level.
From 1971 onwards, a private company dumped mainly particularly hazardous waste that had arisen from production processes, environmental protection measures or the remediation of contaminated sites . From 1974 the landfill was owned by companies that operated waste oil and mineral oil refineries in Dollbergen . After the negative experience with the Münchehagen hazardous waste dump, the "Lower Saxony hazardous waste dump Hoheneggelsen GmbH" took over the dump in 1987 as a state company . In 1993 plans were announced to significantly expand the landfill to a capacity of 1.6 million tons of waste. In contrast, there were almost 1,800 objections from affected citizens. The emplacements ended with the backfilling of the Polder West at the end of 2005. A total of 1.4 million tons of hazardous waste were emplaced.
Redevelopment
Since the last emplacement in 2005, the landfill had been in the so-called decommissioning phase until 2008. During that time, a surface sealing system was applied as a layer of clay several meters thick. A recultivation layer with vegetation was laid over it. The existing operating facilities on the site were demolished, such as a sewage treatment plant, administration building as well as pipelines and manhole structures. The measures cost 3.8 million euros up to the final shutdown at the end of 2008. Since then, the landfill has been in the long-term aftercare phase lasting at least 30 years, during which monitoring of the escape of toxic substances is carried out.
