Dyckerhoffbruch

from Wikipedia, the free encyclopedia

The Dyckerhoffbruch is a former limestone quarry and today's landfill in the district of Biebrich of the Hessian state capital Wiesbaden .

location

The Dyckerhoffbruch is located south of downtown Wiesbaden . To the northeast of the site is Erbenheim and to the east is the Fort Biehler settlement with the Erbenheimer Warte . To the southeast lies the Hesslerhof and to the south of Mainz-Amöneburg . To the south-west are the Wuth'sche brewery , the federal motorway 671 , the Wiesbaden Ost train station and the Kalle-Albert industrial park . The valley of the Salzbach with the hammer mill runs to the west . The south cemetery is located north of the quarry . The tracks of the Ländchesbahn and the Breckenheim – Wiesbaden line , the valley of the Waschbach and the federal highway 66 run north of the landfill, but south of the disused “Kalkofen” quarry.

Quarry

Consisting of the tertiary native limestone was in 1870 through the company's Portland Cement Factory Dyckerhoff & Sons in Mainz-Amöneburg reduced and increases the space in the following decades, again and again. Over a period of 138 years, over 110 million tons of limestone were extracted to make cement .

Landfill

From 1950 to 1968 the “Landfill Mainzer Straße” southeast of today's motorway junction Wiesbaden-Mainzer Straße was filled, and from 1964 to 1983 landfill section I of the Dyckerhoff quarry immediately next to it was filled. These two areas, which have already been recultivated, together have a volume of around 17.7 million m³ and a total area of ​​around 28.6 hectares. First of all, the soil and rubble were used to backfill the areas, and from the 1970s on, garbage from the waste shredding plant on Mainzer Strasse was also used . By the end of May 2005, around 20 million cubic meters and 29 million tons of domestic and commercial municipal waste, respectively, had been deposited in Sections I and II. Since June 2005, the disposal of untreated waste has been prohibited in Germany due to the TA Siedlungsabfall (TASi). Since then, inert waste such as ash from waste incineration plants , foundry sand, soil or asbestos has been stored in Section III. In particular, almost all asbestos waste from Hessen and from other European countries was dumped. Between 1992 and 2016, around 8 million tons of waste were deposited in Section III, of which around 30% slag and ash, 24% used foundry sands, 20% soil, 11% construction waste and 10% asbestos. In 2016, 56% of the deliveries came from Wiesbaden , 29% from the rest of Hesse, 13% from the rest of Germany and 2% from abroad.

In order to ensure disposal for at least two decades beyond 2020, a plan approval procedure has been initiated for a further section with around 2.5 million cubic meters of deposit volume; further sections are being planned.

The leachate from the landfill is cleaned with an industrial sewage treatment plant and the landfill gas is used in a combined heat and power plant. In December 2008, a photovoltaic system with an area of ​​around 1  hectare and a peak power of 900  kW was put into operation on the landfill . In a research project, it was investigated whether the Dyckerhoffbruch is suitable for landfill mining , but only a low raw material potential was identified.

The landfill site is around 1.5 km² in size, almost two thirds of which are used as landfill  areas. Two educational trails provide information about the history, structure and operation of the landfill, the combined heat and power plant and the landfill pond.

Geology and conservation

About a third of the landfill area was recultivated after backfilling and protected as a biotope as a compensation area and retreat for animals and plants . There were, among others, white stork , gray heron , black kite , goshawk , buzzard , Golden Oriole , owls and nightingales sighted. The white storks living around the Schierstein waterworks use the landfill to provide food. The northernmost quarry "Kalkofen" will not be backfilled, but will be preserved as a 39 hectare biotope with pools, meadows and steep walls.

In the Dyckerhoffbruch rock strata can be reached that are up to 500 million years old and come from the Cambrian . From the Pleistocene can Mosbacher sands are developed. In the archaeological site were fossils and archaeological finds , such as pottery shards and bones discovered.
