The Process
CarbonYarn™ converts industrial CO₂ into a premium textile fiber that stores carbon for the life of the textile through a closed, three-stage process, replacing trees and oil as feedstock without compromising on quality.
Industrial CO₂ from a host site is captured and concentrated, running on low-grade waste heat to keep the energy footprint minimal.
Captured CO₂ is converted directly into cellulose through a proprietary, closed process operating at near-ambient temperature and pressure.
The cellulose is spun into continuous, textile-grade fiber and wound onto spools, a yarn that stores carbon for the life of the textile, engineered to drop into existing textile supply chains.
Three stages, one continuous system. See it run.

FAQ
The process is computationally validated only and has not yet been run at bench or pilot scale. CarbonYarn is now in Phase 2, customer discovery and lab validation. The next milestone is a bench-scale proof of concept, with pilot production targeted for 2028 to 2029.
No. CarbonYarn does not yet produce, sell, sample or price fiber. This page will say so plainly when that changes.
That is the target, and for now it is a modelled result, not a measured one. In silico modelling puts the net carbon balance at approximately -1.5 kg CO₂e per kg of fiber, which means more carbon is stored in the fiber than the process emits. The figure will be tested and refined at bench scale, and it should be read as an estimate until then.
No. CarbonYarn describes this as carbon storage: the carbon is physically built into the fiber and held for the functional life of the textile. It is not presented as permanent removal, and it is not an offset.
Viscose and Lyocell are cellulose fibers made from wood pulp. CarbonYarn aims to make cellulose from captured CO₂ instead, and to spin it into a Lyocell-grade fiber. The target is a premium material comparable to TENCEL in performance. That comparison is a design target based on modelling, not a tested result.
No. Carbon fiber is a rigid industrial composite material. CarbonYarn is developing a soft cellulose textile fiber for apparel and fabrics, and the name refers to its carbon source.
