About us: The company

C-biotech, a subsidiary of the Belgian family-owned construction group Cordeel Group, is acquiring the German production site for hemp insulation materials in Nördlingen together with the Dutch HempFlax Group. The activities will be continued retroactively as of 1 November 2025 in a new jointly owned company under the name C-HempFlax Building Solutions GmbH. With this acquisition, both partners are taking an important step in further expanding bio-based and circular building solutions in Europe.

The acquired production site—the oldest of its kind in Europe—will continue to focus on manufacturing high-quality hemp insulation materials for the construction sector. By combining technological expertise, raw-material know-how, and market access, C-biotech and HempFlax aim to scale production and significantly expand the range of sustainable, bio-based insulation materials. In doing so, C-biotech once again underscores its ambition—and that of its parent company Cordeel—to play a pioneering role in sustainable innovation and in the transition toward a circular economy.

“With C-biotech, we provide holistic solutions for carbon sequestration, soil remediation, and circular raw-material use—particularly through bio-based materials. Hemp is an exceptionally valuable raw material in this context because it is enormously versatile and can be used for all of these applications: as a circular feedstock for building materials, to bind carbon and other pollutants for remediating contaminated soils, or to regenerate soils after intensive agricultural use.”

“This investment also underscores the Cordeel Group’s clear ambition to play a pioneering role in greening the construction industry—an industry that is still highly burdensome today and accounts for a large share of our water, energy, and raw-material consumption. Bio-based, circular materials play a decisive role in this.”

“We are happy to have signed with Kingspan. With its outstanding insulation expertise and access to important markets in Europe, Kingspan will be able to drive the growth of hemp insulation, and in doing so, provide a solution that offers a low-embodied carbon insulation when compared with traditional alternatives.”
