Bathing lake instead of rubble at the old quarry in Löppenheim

WBecause “structural conditions have changed”, the city of Mainz does not want to build its own rubble dump at the former Oppenheim quarry. Plans dating back to 2010, which were vigorously opposed by the citizens’ initiative “Mainz 21/No Mainz Landfill Site”, envisage the creation of a waste mineral deposit area for the first and second landfill in the area that was to be backfilled anyway to hold. According to the city council decision, however, the expressly planned site should not be allowed to use more hazardous materials such as asbestos and slag from waste incineration.

The surprising announcement of the head of the environmental department Janina Steinkrueger (Die Grünen), who announced the end of the controversial project shortly before Easter, was rated well and correctly in the initial reactions of representatives of almost all the council parties. Finally, the new full-time deputy managed to name three reasons for the role in reverse.

Ancestor Eder was against disposal tourism

Her predecessor and party friend Catherine Eder has long defended the plan to dispose of construction waste that accumulates in Mainz in the city itself, against strong resistance from the local population. Not least that Eder did not want waste tourism with the prospect of long transport trips. In the meantime, Steinkrüger says, a decision on expanding the Dyckerhoff landfill in neighboring Wiesbaden has been made and approved. This means that “new regional capabilities” are available. The city said the waste disposal company, which was told until 2015 that there was no space on the other side of the Rhine for non-combustible and non-recyclable construction waste from Mainz, had already started negotiations on inter-municipal cooperation with Wiesbaden. .

In addition, Mainz will probably have to deposit the idea of ​​being able to accommodate larger quantities of Mombacher Hochstraße, which is already on the verge of demolition, in the old Laubenheim quarry. As experts currently assume the building, which can no longer be preserved and resembles the Ludwigshafener Hochstrasse, is probably so contaminated with asbestos that demolition materials should not be brought to the planned Mainz landfill anyway. The nearly 1.4 kilometer long prestressed concrete structure, which was closed to traffic a good year ago, was constructed in 1969 as the first segment of a city ring road that was eventually unfinished.

Stability is in question

Additionally, thirdly, the stability of the Loppenheim slope assigned to storage has been questioned in hydrologic reports. Even if there are “technical solutions” for such cases, the project will likely be significantly delayed, so that the landfill project will eventually become a financial risk. This is exactly why the head of the department wanted to abandon the project this summer and then backfill the former quarry and replant it. It may take anywhere from ten to 15 years.

The CDU has already revitalized the old bathing lake proposal. The SPD and the Greens want to ask the people of Mainz first. The citizens’ initiative is still skeptical at the present time, despite all the joy in the cancellation.
