07. Nov 2022 In total more than 70 million euros for in Marl

A VISION PUT INTO PRACTICE is a unique opportunity: for companies with commitment, the economy and the people in the region.

Investors receive access to a modern industrial and business estate that has been planned with foresight. Located in the heart of Europe, opens the gateway to the Ruhr region and to important European economic areas. With its connection to the closely meshed motorway, rail and canal network, offers the best prospects, especially for internationally active companies.

The transformation of the more than 90-hectare former mining site into a promising business location secures work and employment for the people in the city and the region – just as mining did for more than a hundred years before…

With the revitalisation of the former mining site, the city of Marl and RAG Aktiengesellschaft are providing a sustainable impulse for the regional economy and supporting structural change in the region with their commitment to the development of the mine site. Together, the city and the company are creating new life at an old colliery.

In developing, we also keep a careful eye on the aspects relevant to local residents.  We see broad acceptance for in the neighbourhood and the public as an important building stone for the success of our project.

On this website we will keep you up to date on and invite you to accompany us on our way into the future. You too can be part of our vision!

In total more than 70 million euros for in Marl

7. November 2022 | Rubriken: Uncategorized

The district government of Münster has now approved a total of more than 17 million euros in funding for GmbH in an amendment notice. The exact amount is 17,123,643.92 euros, which will be used to support the development of the industrial and commercial area on the site of the Auguste Victoria 3/7 mine in Marl, which was closed down in 2015.

District President Andreas Bothe handed over the funding notification to Michael Dinklage and Volker Duddek, both managing directors of GmbH, on Friday, 4 November. Marl’s mayor Werner Arndt, Michael Kalthoff, chairman of the management board of RAG Montan Immobilien GmbH, as well as Andreas Täuber and Dr. Andreas Schützendübel, chairman and vice-chairman of the town planning committee, were also present at the handing over of the notice in Marl.

“This project is an investment in the future of the region, as it focuses on the economic development potential of the area. Not only Marl, but the entire Emscher-Lippe region will be able to benefit from Therefore, I am very pleased to be able to personally hand over this notification of the increase in funding today,” said Andreas Bothe.

“ is the future project for Marl and the Emscher-Lippe region,” says Werner Arndt. “Up to 1,000 additional and urgently needed jobs and apprenticeships are to be created at the former Auguste Victoria 3/7 mine over the next few years.” The renewed high level of federal and state funding is enormously important “to open up new prospects for the future, especially for future generations.”

In 2019, GmbH was already approved for a grant of 14,585,099.30 euros. Now an increase of a further 2,538,544.62 euros has been approved for the same project purpose, resulting in a total of the above-mentioned funding amount of more than 17 million euros.

The goal of the project is the development, preparation and marketing of commercially used areas with a size of about 12.5 hectares. It is intended to strengthen the adaptability, competitiveness and self-reliance of the region around the city of Marl, which is affected by structural change. This is intended to compensate for the loss of many jobs as one of the effects of the end of coal mining.

The site is also an attractive location for international companies, as it is closely connected to the motorway, rail and canal networks. The development measure is expected to attract new companies and thus create up to 1,000 new jobs and apprenticeships.

The total eligible expenditure amounts to 20,256,287.69 euros. The funding rate is 90 percent. The funds come from the Federal-Land Joint Task “Improvement of the Regional Economic Structure” (GRW) and are borne half by the Federal Government and half by the Land.

A look into the future of

3. November 2022 | Rubriken: Uncategorized

The gateway to the future has already opened wide – this is the impression many of the 90 or so citizens took away from a tour of the construction site.

First-hand information

They were guided by the project managers of GmbH, RAG Montan Immobilien GmbH and the city administration, who answered a wealth of questions at three stations. In the presence of Mayor Werner Arndt, the afternoon ended in late summer temperatures with a snack on the construction site. The response was positive: the guests welcomed the opportunity to talk to those responsible directly on the site at eye level and expressed their gratitude for the offer.

Focus on the entire site developement

The guided tour of the construction site focused on the entire development of the former Auguste Victoria 3/7 mine. It became clear that many citizens are not yet familiar with the two-stage development of the site: In the first project phase, the former power plant area and the northern mine area on Nordstraße are being developed by GmbH for marketing from 2024. The areas to the south of the existing buildings, which are currently used by the city administration, are only planned for development after the RAG Group has completed the dismantling.

Preparation of the power site is in full swing

The interested citizens had met at the construction container on Nordstraße, where the preparation of the former power plant area is already in full swing. Since the start of construction in May, about 10 hectares have been prepared, so that the sheer size of the area is immediately apparent. Managing Director Volker Duddek reported that the area is now being filled by about 2.5 metres – partly with soils obtained during the excavation of the new rainwater retention basins, so that additional lorry journeys can be saved. At the same time, GmbH is examining together with the construction company Heitkamp whether further soil deliveries can be transported via the canal in the future. “That would be the best solution for the residents,” said one participant. Currently, an average of 40 trucks per day access the areas.

Developement measures for the entire site anticipated

Another point of contact was the rainwater retention basin, where Georg Wiebringhaus, project coordinator and authorised signatory of GmbH, presented the infrastructure measures – including the extension of Carl-Duisberg-Strasse into an avenue with cycle paths on both sides and two roundabouts. Important: All current infrastructure measures such as road construction, civil engineering and drainage are designed to anticipate the development of the entire area (development phases 1 and 2). Thus, all the necessary pipes, cables and fibre optics are already being laid in utility ducts along the road. “We are deliberately tackling this in one step so that construction work on Carl-Duisberg-Strasse is not required again in the second phase of the project,” said Mayor Werner Arndt.

Several questions were aimed at noise protection. For example, residents of the Zollvereinssiedlung reported that noise pollution from the nearby motorway and the chemical park was already high. Those responsible for the demolition promised to preserve the existing noise barrier as far as possible and to examine a later extension in the south of the mining area.

Interest in the energy concept

Many participants were also interested in the energy concept: “A big advantage is that we can offer future users district heating, gas and even hydrogen – everything is available,” explained Volker Duddek. Mayor Werner Arndt added: “We are planning a very clean, very innovative industrial area here. Today, that also means that the companies will base their energy supply to a large extent on renewable sources – from solar energy on the roof to heat pumps and rainwater utilisation.”

View of the second developement phase

On a hill overlooking the southern areas still under mining law, Robert Bures and Thomas Middelmann from RAG Montan Immobilien GmbH explained the status of the deconstruction work: Within the framework of the final operating plan procedure (ABP), mining here has the obligation to restore all areas to their original condition and make them suitable for use. Only then will the areas be released from mining supervision and can be put to a new use through a separate urban land use planning procedure. Then the citizens will again be able to contribute their ideas within the framework of the early public participation for the preparation of the development plan. The basic principle is that the southern areas are intended for small-scale commercial settlements such as crafts and manufacturing with low emissions.

1,000 additional jobs and apprenticeships

On the site of the former Auguste Victoria 3/7 mine, the city of Marl and RAG Montan Immobilien GmbH, the developer of mining sites, want to attract innovative companies. Up to 1,000 additional jobs and apprenticeships are to be created there in the next few years, opening up new prospects for the future, especially for future generations. “Thousands of industrial jobs have been lost due to the end of mining in Marl,” says Marl’s economic development manager Dr Manfred Gehrke. “If young families are to live, work and shop in Marl, then we urgently need new jobs.” Marl’s mayor invites to a citizens’dialogue
