Leverkusen, Germany – Covestro has introduced polyether polyols made using ‘bio-circular’ feedstock (with renewability calculated using the mass balance approach). This complements its introduction of renewable TDI and climate-neutral MDI (its climate neutrality based on an internal cradle-to-gate assessment reviewed by TÜV Rheinland).
As Covestro now has sustainable polyols to add to its renewable and climate-neutral isocyanates, its customers can make PU foams entirely from alternative raw materials. The polyols are produced with renewable precursors – from biowaste and residual materials – which are allocated to the products using a mass balance calculation.
Covestro produces the polyether polyols in Dormagen, Germany, using the mass-balanced precursor propylene oxide produced at a JV site it shares with LyondellBasell in Maasvlakte, Netherlands. Both the Dormagen and Maasvlakte sites are certified according to the internationally recognised ISCC PLUS standard.
‘With the introduction of both main components for polyurethanes based on alternative raw materials, we have reached another important milestone on the road to climate neutrality,’ said Sucheta Govil, chief commercial officer of Covestro.
Covestro says its sustainable polyether polyols and isocyanates can be used as a ‘drop-in’ solution, without the need for technical modifications, while offering the same quality and properties as their fossil-based counterparts. The bio-circular products can be distinguished from fossil counterparts through the ‘CQ’ suffix in the product name.
