Covestro to Deliver Bio-Attributed MDI to Carlisle Construction Materials

Covestro will supply Carlisle Construction Materials with Methylene Diphenyl Diisocyanate (MDI) produced from ISCC PLUS certified mass-balanced bio-circular raw materials, offering a product carbon footprint reduction of up to 99% compared to traditional fossil-based MDI. With a CO2 reduction potential of 2.4 kilograms per kilogram of MDI produced, this collaboration will enable Carlisle to manufacture its high-performance polyiso-insulation boards with substantially lower embodied carbon. This partnership underscores a shared commitment to advancing sustainable practices in building materials.

The partnership between Covestro and Carlisle builds on a long history of joint innovation in the construction industry. As sustainability goals for the built environment continue to evolve, both companies are poised to advance and unveil the next generation of insulation materials, reflecting their commitment to addressing emerging environmental standards and enhancing energy efficiency in construction.

Covestro will provide Carlisle with its Mondur® CQ 489 MS isocyanate. The "CQ," standing for "Circular Intelligence," signifies Covestro’s range of circular products that incorporate at least 25% alternative raw materials sourced from biomass or recycled plastics. This highlights Covestro’s commitment to integrating sustainable materials into its products, supporting both companies' efforts toward more environmentally responsible construction solutions.

Hermann-Josef Doerholt, Covestro's global head of Performance Materials, emphasized that Covestro’s commitment to becoming fully circular involves advancing research and development to help meet the scope 3 sustainability goals of its customers, such as Carlisle. He highlighted that Covestro has set some of the most ambitious sustainability and climate targets in the chemical industry. As the company makes progress toward these targets, the positive impacts extend throughout the supply chain, benefiting all stakeholders involved.

Steve Schwar, President of Carlisle Construction Materials, stated that the company has consistently led the development of high-performance construction products with a strong focus on sustainability. He highlighted that the introduction of their new bio-based rigid foam insulation underscores Carlisle's dedication to environmental responsibility and provides customers with cutting-edge building materials. Schwar also emphasized the crucial role of their partners in achieving this bio-based insulation, noting that their collaboration not only advances material science but also supports the construction industry's shift towards a more sustainable future.

Covestro operates ISCC PLUS certified facilities across all major global markets, including its Baytown, Texas manufacturing site. Aligned with its goal of becoming fully circular, Covestro is targeting operational climate neutrality for scope 1 and scope 2 emissions by 2035, and for scope 3 emissions by 2050. The company currently offers hundreds of circular CQ products and is actively broadening its product portfolio to support its sustainability vision.

Carlisle Construction Materials, a global leader in building envelope solutions, has set an ambitious target to achieve net zero emissions by 2050. The company will manufacture bio-based rigid foam insulation with 5% bio-circular content for its SynTec, Versico, Hunter Panels, and WeatherBond brands. This advanced bio-based insulation represents the latest addition to Carlisle’s expanding portfolio of sustainable building products, reinforcing its commitment to innovative and environmentally friendly construction solutions.
