Borealis, Infinium, and Fullstride Ventures have introduced a new high-performance foam made from captured CO₂ emissions, marking a breakthrough in sustainable materials for the apparel sector. One of the first applications of this innovation is Fullstride’s carboncup bra cup, designed to bring circularity into intimate apparel.

The foam is created through a multi-step process that begins with capturing waste CO₂ that would otherwise enter the atmosphere. Infinium’s proprietary technology converts this CO₂ into eNaphtha, a low-carbon substitute for fossil-based naphtha. Borealis then polymerizes the eNaphtha into polyethylene, which is used to produce the foam. The resulting material works seamlessly with existing manufacturing and recycling systems while meeting the demanding requirements of apparel products.

Fullstride’s carboncup is the first commercial use of this foam. Made partly from CO₂-derived eNaphtha, it provides the same comfort, breathability, and durability as conventional foam bra pads but with a much smaller carbon footprint compared to traditional fossil-based polyurethane.

“This breakthrough innovation not only diverts carbon from the atmosphere but also reduces reliance on finite fossil resources,” said Yossi Nasser, CEO of Fullstride. “It significantly lowers our product’s carbon footprint and represents a meaningful step forward for sustainable fashion.”

“Together with Fullstride and Borealis, we’re reimagining what carbon can be,” said Robert Schuetzle, CEO of Infinium. “By creating eNaphtha that enables Borealis to produce next-generation plastics with far lower emissions, we’re helping industries move toward a cleaner future.”
