The full-service activated carbon provider with roots in the Ruhr region
To understand what makes us special as the CarboTech Group, it is important to know our roots. After all, they are what made our development possible in the first place. Our production facilities are located right in the center of the Ruhr area. Everything from production and finishing to the packaging of our customized products takes place here.
In addition to the continuous expansion of our product portfolio and our production and processing capabilities, CarboTech customers also benefit from our comprehensive full-service offering with our own service fleet. The CarboTech service fleet, which includes silo vehicles, multi-compartment vehicles and trucks, is also managed directly from our headquarters, so that our customers receive everything from a single source.
Through constant transformation and further development, we can proudly and confidently say today:
We're: GERMANY'S LEADING FULL-SERVICE PROVIDER IN THE FIELD OF ACTIVATED CARBONOur heart beats in the Ruhr regionThe roots of our group of companies lie in the Ruhr region. After all, nothing is more symbolic of coal mining than the “coal pot”. But even though the coal mining era is now a thing of the past, the values of the Ruhr region have survived in our company. The partnership-based exchange with our customers in our honest, direct manner, our reliability and our active commitment to solving problems for our customers are important cornerstones that our customers can always count on.Tradtition and experience – a bridge to the future
Rooted in a heritage of German mining research and the local coal industry, CarboTech combines experience in production, application and process engineering. We see ourselves in the tradition of all those who are forever drawing knowledge from science and technology in order to apply it in ways that are economically viable for the benefit of people and their environment. That’s why we research and develop solutions to reduce environmental pollution and health hazards.
Strategically, we are guided by conventional requirements as much as by innovative applications and services. Our experts are conversant with the challenges of real-life settings, and it is precisely this engagement that our customers really appreciate.
Quality and economy
As the successor to CarboTech Aktivkohlen GmbH, CarboTech today presents itself as a modern, medium-sized company that also offers training apprenticeships. With our unswerving focus on the customer, we’re constantly working on improving what we do. High demands of product quality and service quality are something we absolutely expect.
Use of our activated carbons opens the door to new solutions that are as reliable as they are economical. Our experienced specialists rise to the challenge of this complex, demanding task each day – and do so with great success.
History
In Business since 1956
After world war 2, the Bergwerksverband GmbH (mining association) began setting up experimental facilities for the production of purest carbon and activated carbon. Thanks to many years of experimenting, it proved possible to produce very high quality activated carbon from hard coal. In 1955, a large-scale pilot plant was erected on the site of the former Queen Elisabeth coalmine in Essen and on February 29th, 1956, it was put into operation. This was the beginning of the company history of CarboTech AC GmbH.Foundation
