LANXESS has strengthened its portfolio of sustainable construction materials with CAB 30, a low-emission calcium sulfate (anhydrite) binder designed for environmentally responsible building applications. The product has been independently assessed and certified, underscoring its contribution to reduced carbon impact and healthy indoor environments.
Environmental Product Declarations (EPDs) issued by Institut Bauen und Umwelt e.V. (IBU) confirm the environmental performance of CAB 30 as well as conventional calcium sulfate screeds produced with the binder. These declarations provide transparent, science-based data across the product lifecycle—from raw material extraction through production and end-of-life—highlighting its comparatively low carbon footprint.
CAB 30 also complies with stringent requirements for volatile organic compounds (VOC). Emission testing verifies that the binder meets the criteria established by the Committee for Health Assessment of Building Products (AgBB). Additional approvals include compliance with Belgian VOC regulations. In France, the product has achieved the “Emissions dans l’air intérieur A+” classification, recognizing very low indoor air emissions, including in formulations that incorporate additives such as Mebonit pro or Mebofix pro. CAB 30 is standardized in accordance with DIN EN 13454.
When used in calcium sulfate screeds, CAB 30 offers practical and ecological advantages over traditional cement-based systems. The screeds can be installed across large areas without joints or reinforcement, supporting efficient construction processes.
The Mebofix pro drying accelerator further enhances performance by reducing the water requirement during mixing and significantly shortening drying times. Lower water content improves compressive, flexural, and surface strength while contributing to resource efficiency and reduced on-site emissions.
With CAB 30 and its verified environmental documentation, LANXESS provides architects, engineers, contractors, and developers with reliable data and high-performance materials to meet the growing demand for sustainable, low-emission construction solutions.
