H&M's Shocking Move: Could CO2 Clothing Change Fashion Forever? You Won't Believe the Details!

The fashion industry faces a significant challenge: it generates a staggering amount of waste, with an estimated one garbage truck of textiles discarded every second. This issue is compounded by the industry's environmental impact, producing more carbon pollution than international flights and maritime shipping combined. As consumers and environmental advocates increasingly call for sustainability, some companies are experimenting with innovative ways to recycle textile waste and develop new materials that forgo fossil fuels.

One such startup, Rubi, is at the forefront of this movement. Co-founder and CEO Neeka Mashouf described the company's approach as "basically taking the machinery of biology outside of the cell" to create building blocks for lyocell and viscose. This technology, which captures carbon dioxide to produce cellulose, has the potential to revolutionize the textile industry.

Recently, Rubi secured $7.5 million in funding to construct a demonstration-scale production system capable of generating tens of tons of material primarily from CO2. The investment round, led by AP Ventures and FH One Investments, also attracted participation from notable firms such as CMPC Ventures, H&M Group, Talis Capital, and Understorey Ventures.

Rubi has already established over $60 million in non-binding off-take agreements with several partners, including major players like H&M, Patagonia, and Walmart. Their innovative approach utilizes enzymes to create cellulose, distinguishing them from other startups that might rely on engineered bacteria or chemical catalysts in their processes. Currently, most cellulose is sourced from trees, often leading to deforestation and environmental degradation.

“These textile and raw material supply chains are very long,” Mashouf explained. “Here in the U.S., we’ve gotten interest in being able to actually produce cellulose pulp that’s textile grade, where that doesn’t exist today.” The duo behind Rubi, Neeka and her twin sister Leila, who is studying medicine at Harvard Medical School, turned to enzyme technology after evaluating various options. “We looked at all the tech out there,” Neeka said, “but we kept coming back to enzymes.”

The enzyme industry is already massive, utilized in products like high fructose corn syrup and wastewater treatment. Rubi’s method employs a “cascade” of enzymes to process waste carbon dioxide, with AI and machine learning enhancing the enzymes’ efficacy and stability. In their reactors, carbon dioxide is added to an aqueous solution containing the enzymes, resulting in the formation of white cellulose within minutes. The system is designed to fit within shipping container-sized modules, with plans for future continuous production.

Initially targeting apparel companies, Rubi hopes to expand its cellulose production capabilities to serve any industry that utilizes cellulose. “This really is a platform,” Mashouf asserted. “We think of it as a platform to make all the important chemicals and materials across the economy in a low-cost way.”

As the fashion industry grapples with its waste crisis, the emergence of companies like Rubi presents a promising solution. By transforming carbon dioxide into valuable materials, they not only address sustainability concerns but also pave the way for a more circular economy in textile production. The implications of this technology extend beyond apparel, potentially impacting various sectors reliant on cellulose and driving broader environmental change.
