Röhrig granit informs citizens about expansion plans

By | Uncategorized

Around 250 citizens accepted the invitation to the RÖHRIG granit information event on November 20, 2018. The topic was the planned extension of the quarry toward the south. The concrete plans were presented in the village community center in Sonderbach. Local residents, neighbors, suppliers, and customers from the region also had the opportunity to discuss their questions directly with company representatives and other experts.

And this is how the planning looks like: after the necessary preparatory work had been carried out in recent years, the application for the expansion is expected to be submitted in spring 2019. Before submitting the application, it was essential to inform the interested public about the project, and to answer their most pressing questions and concerns. At the beginning of the event, Managing Director Marco Röhrig welcomed the guests and underlined the importance of the expansion project for the company. In order to be able to continue production at today’s level, an expansion would be necessary. With the protection of the site also the 90 jobs, the raw material supply of the region, and the supply of the customers with the high-quality products from the refinement plant could be guaranteed for years.

Afterwards, project manager Martin Buschmann from the Aachen engineering company SST presented the concrete plans for the expansion. The plan is for an additional area of 6.2 hectares in a southerly direction.

In the second part of the event, the citizens had the opportunity to obtain information about the company, the expansion project, and its activities in the fields of blasting technology, dust, noise, and protection of species at various information stands. In addition, the company explained all measures to reduce dust and noise emissions, as well as further steps to keep the vibrations at the same or similar level as today. Company representatives and external experts, including from the Nature Conservation Association (Nabu), answered questions at various information boards. Many interested parties used the opportunity for an intensive personal exchange – before, during, and after the event. Topics included the measurement of vibrations and dust emissions, long-term corporate planning, and nature conservation issues.

If you were unable to attend the event, you will find the most important information about the project here. At the end of the event, Marco Röhrig offered again to continue the dialogue with the citizens if there are further questions regarding the enlargement.

Röhrig Granit wants to expand quarry

By | Uncategorized

The Röhrig Granit company in Sonderbach plans to expand its quarry toward the south. This was announced by managing director Marco Röhrig at a press conference on Tuesday. The reason for the expansion? “Otherwise, we will have exhausted the capacity of the quarry in a few years’ time”, Röhrig said.

He represents the fifth generation to run the family business with its current 90 employees. About 6.2 hectares of protection forest have to be cleared for the project, and some hiking trails have to be relocated. “We are reforesting the forest in another place, and are taking care of the relocation of the hiking trails”, promises Marco Röhrig.

A maximum of two blastings per week

The distance to the Juhöhe settlement south of the quarry should also remain at least 400 meters. “It is not a question of increasing production – mining should continue at the same level as before”, Röhrig stressed. The number of blastings and the number of trucks transporting the material should also remain the same, as should the noise level. “As before, there will be a maximum of two explosions per week”, said Röhrig. “By using new blasting technology, we will only reach ten to fifteen percent of the permitted noise limits, and that should remain so”, he added.


At an information evening in the village community center in Sonderbach on Tuesday, November 20, at 6.30 p.m., residents can get an idea of the planned expansion for themselves. Among other things, posters on the status of the plans will be shown, and questions will be answered. (rori)

The new site is to supply granite for the Lampertheim mineral materials plant for around 30 years. However, the expansion of the quarry also involves an enormous amount of work: In addition to the forest and the hiking trails, the viewpoint “Gerhard-Röhrig-Rast”, which is currently on the edge of the quarry, will also have to be relocated. There is also a sea of rocks in the area that has been designated a natural landmark. “We will also relocate the sea of rocks, i.e. move the stones to another location and create an artificial sea of rocks there”, explained engineer Martin Buschmann, a specialist from the consulting firm SST. He accompanies the application to the responsible regional council in Darmstadt. The project has been planned since 2014. “The application is to be officially submitted in spring 2019”, he said. However, it will probably take another two years before the final decision is made. In addition, a second sea of rocks in the surrounding area is to be declared a natural landmark as a substitute.

Also the protection forest is not to suffer from the development: As compensation for the deforestation of the 6.2 hectares of protection forest, further areas to the south that have not been under special protection so far will be declared protection forests. “Fortunately, the forest is not a breeding area, but only a hunting area for bats”, he explained. The company has also been cooperating closely with Nabu Heppenheim for years – also to protect the special fauna of the quarry.

According to Buschmann, the quarry in Sonderbach is so important for the company because a unique granite quality can be extracted here. And Röhrig added: “It doesn’t matter for road construction, but niche products are becoming increasingly important for us – for example, for use in rubber, laminate, composite materials, children’s modelling clay, or as a base material for aquariums.

“We regularly publish information on our website, will name a contact person for the citizens, and also want to set up a box where the residents and neighbors can submit suggestions and questions”, said Florian Weisker, managing director of the “Vom Hoff” communications agency, which is responsible for public relations for the project. “We take our responsibility as a family business in the region seriously – in contrast to the quarries in the surrounding area, which are all in the hands of large corporations, we promote cultural and social institutions in the vicinity”, said Röhrig.
