FenX AG

FenX AG is a Swiss materials company that converts mineral waste into high-performance insulation materials for the building industry. Its work sits at the intersection of materials science, waste valorisation and construction, applying technical development to two sectors simultaneously: building and construction, and waste management.

The company's core product is a range of insulation materials produced from mineral waste streams rather than from virgin raw materials. By reprocessing waste mineral feedstocks into functional building products, FenX addresses demand for insulation in construction while providing an outlet for material that would otherwise be discarded.

Technical work at FenX spans materials science, recycling and waste valorisation, and insulation materials development. The company positions itself around sustainability, with its business model built on turning waste into building materials. Further details on founding year, team size and funding are not published.
