The fashion industry is a significant contributor to global climate emissions—accounting for up to 4% of the total. Driven by ever-increasing demand for new clothes (production doubled between 2000 and 2015), the industry faces mounting pressure to reduce its environmental impact. Now, companies like Rubi Laboratories are exploring radical solutions: extracting carbon dioxide from the atmosphere and converting it into usable textile fibers.
The Carbon Transformation Process
Rubi’s approach mimics photosynthesis, but in a bioreactor, using enzymes to rapidly transform captured CO₂ into cellulose—the primary component of plant fibers. This resulting fiber is nearly identical to traditional cellulose-based textiles (like viscose, rayon, or Tencel) but avoids deforestation. The process is comparable to lab-grown meat, but for plant-based materials.
Major brands are already piloting the technology: Walmart and H&M are among at least 15 companies testing Rubi’s carbon capture methods. Scaling production remains a challenge, but the potential is clear—carbon-neutral clothing is now within reach.
Enzymes as the Key Catalyst
Rubi uses a “cascade” of enzymes to accelerate the chemical conversion of CO₂ into cellulose. Trees naturally perform this process, but Rubi’s bioreactors dramatically speed it up. As Rubi Laboratories Senior Scientist Trevor Boram explains, these enzymes act as “biological catalysts” that rapidly convert atmospheric carbon into usable fibers.
Partnerships and Scale-Up Challenges
In 2023, Walmart entered a pilot agreement with Rubi to explore large-scale implementation in its supply chain. Since then, H&M and 14 other companies have joined the initiative. This could be a win-win scenario: Rubi captures carbon while brands meet sustainability goals. However, replicating this reliably at scale is proving difficult.
The Risks of Tech-Driven Sustainability
Several companies have previously failed to deliver sustainable textile solutions due to scaling issues. Renewcell, a Swedish recycling firm, filed for bankruptcy in 2024 despite early funding and partnerships. The key question, as Bolt Threads CEO Dan Widmaier points out, is whether these technologies can “work reproducibly at scale, meeting quality specs… and timelines.”
Beyond Technology: The Role of Consumption
Ultimately, reducing textile waste requires a multifaceted approach. While innovations like carbon capture are promising, curbing excessive consumption remains critical. The fast-fashion model incentivizes quantity over quality, perpetuating waste. A combination of mindful purchasing habits and technological advancements will be necessary to meaningfully address the industry’s environmental footprint.
The future of fashion may well include garments derived from captured carbon dioxide—a symbolic statement that underscores the urgent need for sustainable practices.
