First sports shoe featuring EVA midsole made using captured carbon emissions
Borouge International, Infinium, Sacramento, California, have enabled the commercial launch of the breakthrough CleanCloud technology for Swiss sportswear brand On.
This technology is used in On’s new Cloud X5, the first sports shoe featuring an EVA (Ethyl Vinyl Acetate) midsole made using captured carbon emissions on a commercial scale.
Borouge International enables the production of high-performance, easy-to-process EVA foam used in premium sport shoe midsoles.
On’s new Cloud X5.
The collaboration marks a significant milestone in demonstrating how captured carbon emissions can be transformed into everyday consumer products through existing industrial infrastructure.
Infinium’s e-Naphtha as a drop-in solution
Through this new collaboration, captured carbon emissions are converted into e-Naphtha, creating an alternative carbon source while maintaining the same performance, quality and specifications required for premium athletic footwear.
As Infinium's e-Naphtha is chemically identical to conventional naphtha, it can be processed through existing steam crackers and downstream manufacturing assets without modification. This enables rapid commercialization and scalability across the chemicals value chain.
From carbon emissions to performance footwear
Through the partnership, Infinium supplies Borouge International with renewable e-Naphtha produced from captured CO₂ and renewable hydrogen. Borouge International converts the feedstock into e-ethylene which is transformed into e-EVA, the material that enables On's breakthrough CleanCloud midsole technology used in the new Cloud X5.
The resulting EVA is molecularly identical to conventional EVA, ensuring the same high performance.
Furthermore, every stage of the supply chain, from Infinium's renewable e-Naphtha production through Borouge International's conversion processes and On's manufacturing partners, is ISCC PLUS certified, providing verified chain-of-custody tracking and ensuring the traceability of low environmental impact feedstocks throughout production.
