Sour’s partnership with Herone solves a concrete manufacturing problem: recycled carbon fiber has historically been too unpredictable for structural components, forcing brands to blend it with virgin material or relegate it to cosmetic parts. By developing a repeatable process to transform post-consumer carbon scraps into consistent braided tubes, they’re moving recycled composites from a sustainability narrative into actual supply-chain viability—which means other frame builders can now source without accepting quality trade-offs. This removes one of the last technical excuses preventing carbon-intensive industries from adopting closed-loop manufacturing at scale.
