The innovative, more sustainable raw material Desmodur CQ MS from Covestro, is being used in PU insulation boards by Recticel throughout the Circular House, demonstrating that high-performance polyurethane solutions can support more sustainable construction.

Brightlands Circular Space: Platform for circular collaboration

Located on Brightlands Chemelot Campus in Sittard-Geleen, the Netherlands, the 7,500 m² Circular House will serve as a living lab for demonstrating, co-creating and piloting zero-waste plastic technologies. It integrates sustainable design at every level, using innovative materials to reduce both operational and embodied carbon.

As part of its mission, Circular House aims to share best practices in circular solutions in its Experience Space and host events in which Covestro and Recticel could share knowledge about circular building materials with students and peers as well.

Covestro x Recticel: Jointly furthering sustainability

Covestro’s Desmodur CQ MS is used in Recticel’s “Eurothane Silver Impact” insulation boards, which are now used to insulate the roof of the Circular House at Brightlands.

Desmodur CQ MS is based on climate-neutral methylene diphenyl diisocyanate (MDI), produced using bio-circular feedstocks, certified via the mass balance approach.

As a result, the “Eurothane Silver Impact” boards used in the Circular House contain 43% less embodied carbon compared to standard versions, while maintaining the trusted technical and thermal performance.
