Company Profile

Germany’s leading supplier of activated carbons

CarboTech is one of the world’s leading suppliers of active carbons. Whether it’s in powder form, granulated or extruded – we supply it. Our production facilities are located right at the heart of Germany’s industrial Ruhr conurbation. This is where it all happens: everything from production and finishing treatment to the packaging of our made-to-measure products. As well as activated carbon, we also supply activated cokes and carbon molecular sieves made from hard coal, coconut coke and charcoal.

 

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.
