Carbon Dioxide-Based Foam Materials
Borealis, Infinium & Fullstride Ventures Debut the Carboncup™
Kalin Ned — September 25, 2025A collaborative effort between Borealis, Infinium, and Fullstride Ventures has resulted in the creation of a new polymer foam material that incorporates captured carbon dioxide as a primary feedstock.
The production process begins with Infinium's conversion of waste CO₂ into a chemical intermediate called eNaphtha, which Borealis then polymerizes to create the base plastic. Fullstride Ventures utilizes this plastic to manufacture a bra cup component, marketed as the carboncup™. The end product is presented as offering performance characteristics equivalent to conventional foam materials, with the added benefit of possessing a reduced carbon footprint.
This novel initiative is positioned as a practical application of circular economy principles within the fashion industry. The collaborators have successfully demonstrated a pathway to transform an atmospheric pollutant into a durable consumer product.
