In the Ruhr region, a former mining be treated areas and as a residential or commercial space markets. With success, the people take on the newly created districts. The brownfields are slowly disappearing.

The winding tower of the former mine Lohberg-Osterfeld surmounted, a district of Dinslaken, the buildings old industry. Some of them are renovated, others have damage to masonry walls or the Windows. The buildings date from the period before the First world war, and are under monument protection.

The architecture and the Patina of this place attracts the people. As Claudia Neumann. It has made a Kibono manufactory in the old gatekeeper’s house independently. Kibono miniature plants, which are rooted in the moss balls. “The absolute Flair. The old mine buildings, such as the wage hall or the adjacent building – this is great.” Claudia Neumann is one of a group of people who have settled here with their studios and shops. Painters, photographers, and designers, the industrial area and bring a new lease of life.

The Area of the mine is developed. Other buildings to be demolished, before they are re-scheduled. The colliery is situated in the Dinslaken district of Lohberg. A place that used to be considered as structural weak.

The wounds in the city to heal”

40 hectares, includes the pure mine site, to prepare the RAG Montan Immobilien GmbH for the commercial and residential market. The company is part of the RAG, the organization of the German coal-mining industry. Main focus is in the areas of reclamation of former mining. The “wounds in the city to heal,” says the Chairman of the Executive Board, Hans-Peter Noll. “We want to leave no scorched earth,” he says. Noll is not a lawyer, Economist or engineer, but a geographer, and that is a good thing. He has a different approach than others.

Influenced by the International building exhibition Emscher Park, he puts the needs of the people in the foreground. Of course he wants to be with the company profitably. But always with the involvement of the citizens. “We always put the residents’ participation. You need to have the acceptance of the people, therefore, we need to define the citizens ‘ will, then the political level in the city councils, and there you need to find someone to do the heart thing. Since it often takes a long time of Persuasion,” explains Noll the process.

Around 9500 hectares of mining area in the mining property, with approximately 2200 buildings. 2, 8 million tonnes of soil is used per year. About 1,200 hectares are currently developed, distributed to city and neighborhood development, the creative quarter for artists, and logistics parks. Often, existing resources are used or developed.

Own Power Supply

As in Lohberg. They want to be independent from energy companies. The methane from the former mine is used. Wind energy comes from wind wheels on a dump, plus the energy from a solar Park that has been installed on the former coal washing plant. All of this is enough to provide power to the district and the accessible end of the site, and to direct Surpluses into the grid. So it is not surprising that in Lohberg, about 70 percent of the residential units are already sold. Also in the case of commercial real estate, it looks good.

In other locations in Neukirchen-Vluyn or Kamp-Lintfort on the surfaces of the former mines in the low-mountain and West will be renovated. Down the mountain is characterised by strong residential development. Kamp-Lintfort is the location of the land garden show in 2020. Until then, a city Park in the urban area. The newly established Rhine-Waal University, a cross-border University in the Netherlands, has been related to the building of the former colliery. This residential property is yet to come.

Soil quality a Central theme

A focus of the work, however, is the nature of the soil. What has seeped in over the decades in the soil, how the soil is contaminated? These are the questions the employees. “We begin with historical Reviews of soil. Then chemical analyses and samples is expected to follow. A Grid of the area is created, so that we have covered the area completely. Only then can we see what we can do where. Later, the area is checked again and again,” says RAG Montan-press spokesman Stephan Conrad.

The floor is in today’s era of environmental awareness, so to speak, one of the business cards of the company. “There used to be a different understanding of Contaminated land. If we are sloppy here once we are done,” says managing Director Hans-Peter Noll objectively. In the 40 years of existence of the company and its predecessor companies, it has come so far, but never to an incident, that an area had to be demolished because the ground was contaminated.

Interest from abroad

So far, RAG Montan has invested around 60 million euros in measures for the revitalization of the areas. This includes 75 million euros in grants just by the Land of NRW. The square meter prices are in comparison with cities such as Düsseldorf or Cologne low. Building land costs between 200 and 240 euros per square meter. For the industrial land, the price is depending on the location, between 30 and 140 euros.

The contaminated soil is not removed from the fields. It is processed in plants in the so-called Landscaping. There is ground dug. Thick plastic, the 200 years will hold, and will be designed plan and the affected soil piled up. Up to six meters of pure earth, which is then planted, and depending on the case. Is accompanied the Whole of a permanent ground water supply.

The projects were abroad on the interest, says press spokesman Conrad. “We constantly have delegations from China or Eastern Europe to visit. In China, there are almost 70,000 mines. Constantly which are closed. The Chinese need the space and are very interested to see how we are doing.”
