In short
CarbonYarn is developing cellulose fiber made from captured industrial CO₂. It is computationally validated only: no fiber has been produced, sold, sampled or priced yet. Its modelled carbon balance is negative, roughly -1 to -2 kg CO₂e per kg of fiber, reported as carbon storage, not removal and not an offset.
What is CarbonYarn?
What is CarbonYarn?
CarbonYarn is developing a way to turn captured industrial carbon dioxide into textile-grade cellulose fiber, so the carbon is stored inside clothing and fabric instead of returning to the air. It is the first venture of the DRG Group of Companies.
How does the CarbonYarn process work?
At a high level, captured CO₂ is converted directly into cellulose, and the cellulose is spun into continuous yarn in a closed-loop process. The detailed method is proprietary and is not published. See the technology page.
What stage is CarbonYarn at?
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.
Does CarbonYarn sell fiber or offer samples today?
No. CarbonYarn does not yet produce, sell, sample or price fiber. This page will say so plainly when that changes.
Where is CarbonYarn based?
CarbonYarn currently operates from Pakistan, with an interest in the region's textile industry.
What does carbon negative mean here?
Is CarbonYarn fiber carbon negative?
That is the target, and for now it is a modelled result, not a measured one. Conservative modelling puts the net carbon balance somewhere between roughly -1 and -2 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.
Is this carbon removal or a carbon offset?
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.
How does CarbonYarn compare with other fibers?
How is CarbonYarn different from viscose and TENCEL (Lyocell)?
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.
How does CarbonYarn compare with polyester and cotton?
Polyester is made from fossil feedstock, and cotton needs farmland and water. CarbonYarn's target is a fiber that uses neither wood pulp nor arable land, with its carbon taken from an industrial off-gas stream. CarbonYarn makes no cost or performance comparison with them until it has measured data.
Is CarbonYarn the same as carbon fiber?
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.
Which regulations affect CarbonYarn?
Does the EU CBAM apply to textiles?
Not directly. The definitive period of the EU Carbon Border Adjustment Mechanism began in January 2026, and it currently covers cement, iron and steel, aluminium, fertilisers, electricity and hydrogen. Textiles are not covered today. For textile exporters the pressure is indirect, coming first from buyers who ask suppliers for emissions data.
What is the Digital Product Passport and why does it matter?
The Digital Product Passport is a requirement under the EU Ecodesign for Sustainable Products Regulation to provide product-level environmental data. It is expected to reach textiles from around 2028, once the detailed rules for textiles are adopted. A fiber with a documented carbon footprint would help brands and mills meet it.
How can I work with CarbonYarn?
Can mills, brands and researchers work with CarbonYarn?
Yes. CarbonYarn is in customer discovery and welcomes conversations with textile mills, brands and research partners. Email partnerships@carbonyarn.co.
