DBR Dortmund Building Material Recycling Gmbh

DBR - started as a consortium, today established as a company on the market

In the second half of the 1980s, demand for road construction picked up after a previous recession. At that time, it was clear from the cities' waste management concepts that the available landfill volumes were becoming scarcer and correspondingly more expensive. The Dortmund companies Höhler , Stricker and the then branch of Teerbau (today Eurovia ) developed the plan for the most comprehensive recycling of minerals possible from these boundary conditions. From a consortium they founded a company in 1988, DBR Dortmunder Baustoffrecycling GmbH.

The reprocessing of rock materials that usually occur in construction was already solved by technology at that time. The companies had set up a plant on Weidenstrasse in the Dortmund harbor area for this task, in which they produced substructure materials for road construction and civil engineering with a crushing and classifying system.

However, the reuse of cohesive excavation soil mixed with stones was not yet possible. In coordination with the 'Planning Group for the Construction of the Dortmund-Nordost Landfill', which later became part of the Disposal Dortmund GmbH (EDG) and provided with a development contract from the Ministry of Economics, the companies worked out a concept for the Reuse of these previously unused substances. DBR built a plant at its own risk to sort out the coarser additions from the soil and send it to the rock recycling process. The fine-grained, cohesive substances were processed in a mixer with aggregates and water to a clay-like homogeneous substance that was suitable for sealing landfills. In 1992, EDG allowed the construction of a test field on the old Dortmund-Grevel landfill. Extensive measurements and investigations were made on this. The goal of using mixed soils, previously treated as waste, instead of natural clay in landfill construction was achieved. DBR then received the order for the surface sealing of the old Grevel landfill.

EDG's operational plans and the technical possibilities now revealed by DBR met in the establishment of a joint company, the Dortmunder Mineralstoffverwertungsgesellschaft (DOMIG). A former Hoesch site with an area of ​​around 150,000 m² on Huckarder Strasse in Dortmund was acquired by EDG. Among other things, the targeted recycling of old mineral building materials has been pursued there since 1994. In 2001, the soil treatment plant was also moved from the Dortmund-Grevel landfill to this location. To this day, DOMIG has worked with DBR to produce clay-like replacement building materials for more than 850,000 m² of surface sealing on landfills in and around Dortmund.
