Everdye’s Revolutionary Dyeing Process Could Slash Textile Industry’s Environmental Impact by Up to 99%

In the colorful world of fashion, there’s a dirty secret lurking behind every vibrant garment: the dyeing process is an environmental catastrophe. Traditional textile dyeing guzzles energy, contaminates water supplies, and pumps greenhouse gases into our atmosphere at alarming rates. But what if there was a way to create those same brilliant colors without the devastating environmental cost?

French startup Everdye has developed a groundbreaking dyeing technology that promises to revolutionize the textile industry by cutting energy consumption by up to 8 times while eliminating toxic wastewater and dramatically reducing carbon emissions.

The Hidden Cost of Color

The textile dyeing industry operates largely out of public view, yet its environmental footprint is staggering. Conventional dyeing processes can account for up to 60% of the total energy used in textile production. The industry is responsible for nearly 20% of global water contamination and approximately 5% of greenhouse gas emissions worldwide.

This environmental burden stems from the fundamental chemistry of traditional dyeing. Manufacturers must force chemical bonds between dye molecules and fibers using extreme heat—often reaching 130°C—along with petrochemical-based chemicals. Deep colors like black can require six to seven hours of processing, consuming enormous amounts of energy and creating toxic byproducts that often end up in rivers and oceans.

From Laboratory Discovery to Industrial Revolution

Everdye’s story begins with scientific serendipity. During her doctoral research across universities in Tunisia, Portugal, and France, co-founder Dr. Amira Erokh was working on a NATO-backed project to develop fabrics resistant to biological attack. While that wasn’t the intended outcome, her research led to a chemical discovery that would become the foundation of Everdye.

“After completing her PhD, she worked in the paint industry in Tunisia before relocating to France,” explains CEO Philippe Berlan. “Through an entrepreneurship program, she realized her chemistry could be adapted for dyeing and began experimenting—literally in her laundry room—building the first working prototype there.”

The company was formally founded in 2021, secured early funding in 2022, and has been scaling its industrial development ever since.

The Physics of Color: A Magnet-Like Mechanism

Everdye’s revolutionary approach harnesses the natural chemistry of fibers rather than fighting against it. During the standard bleaching step required before dyeing, fibers naturally develop negatively charged sites. Instead of counteracting this chemistry, Everdye’s process leverages it.

The company’s pigment functions almost like a magnet. A pretreatment creates negatively charged anchoring points on the fiber surfaces, while the pigment—carrying a positive charge—instantly locks onto these points through electrostatic attraction. The pigment naturally attaches to the fiber at room temperature, and during the drying stage—already part of any dyeing process—polymerization permanently locks the pigment into the fiber.

The result? The same strong color attachment as conventional dyeing, but without the need for prolonged high heat or toxic chemical additives.

Not Your Grandmother’s Natural Dye

When petrochemical dyes first appeared, they solved critical performance problems that natural dyes couldn’t address. They delivered strong, stable colors at industrial scale. However, the environmental consequences were unknown at the time.

“Today, the entire textile industry is built around that petrochemical model,” Berlan emphasizes. “Our goal is not to go backwards to historical dyeing. We are creating new chemistry that combines industrial-quality performance with a radically lower environmental footprint. The industry needs disruption, not nostalgia.”

Environmental and Economic Transformation

Everdye’s technology delivers multiple simultaneous benefits that could transform the economics of sustainable fashion:

• 80-90% reduction in energy consumption compared to conventional dyeing
• Production cycles three to four times faster
• Elimination of toxic wastewater treatment
• 60% to nearly 99% reduction in greenhouse gas emissions
• Bio-sourced pigments produced exclusively from plant-based or mineral raw materials

“All pigments developed by the company are bio-sourced, produced exclusively from plant-based or mineral raw materials,” Berlan notes. “The result is almost clean water at the end of the dyeing cycle.”

The economic case is equally compelling. While green solutions often carry premiums today, Everdye’s strategy focuses on achieving cost parity as production scales. “Our objective is cost parity,” Berlan explains. “Today green solutions often carry a premium. As we scale production, pigment prices will fall, while operational savings—energy, labor, and water treatment—rebalance the economics.”

Seamless Integration for Maximum Adoption

Perhaps most importantly for widespread adoption, Everdye’s technology requires no new capital equipment. Dye houses can integrate the process by simply adjusting their existing parameters with minimal training.

“The market is highly fragmented globally, so we’re focusing first on Europe to strengthen the technology and gain operational experience before expanding,” Berlan explains. “Dye houses don’t need capital investment. They simply adjust process parameters. With minimal training, they can integrate the technology into their existing production lines.”

The company also works directly with apparel brands facing increasing pressure to decarbonize their supply chains, creating a powerful value proposition that combines environmental benefits with business advantages.

The Technical Challenge of Transformation

Textile dyeing is among the most technically complex manufacturing processes in the world. Different fibers, colors, and machine types each represent separate technical variables that must be validated independently.

“Textile dyeing is extremely complex. You have different fibers, colors, and machinery types—each combination is a separate technical challenge,” says Berlan. “The priority is quality and reliability. We want smooth adoption and industrial confidence. Entering this market requires delivering consistent performance.”

Currently, Everdye offers primary colors enabling a wide range of shades, with deep black—one of the most technically demanding pigments—still under development. The pigments are already ready for cellulosic fibers such as cotton, hemp, and linen, with polyester development in advanced stages.

The Cultural Barrier to Change

According to Berlan, the biggest barrier facing the sector is cultural and financial rather than technical. “This is a traditional industry, and change takes time. Factories operate on long-established processes and spreadsheets that favor legacy systems.”

But the environmental and social cost of current dyeing practices is becoming impossible to ignore. Many communities are directly harmed by toxic discharge. The pressure to transform is increasing from regulators, brands, and consumers, and Everdye offers a viable path forward.

As the fashion industry faces mounting pressure to address its environmental impact, Everdye’s technology represents more than just an incremental improvement—it’s a fundamental reimagining of how we create color in our clothes. By combining cutting-edge chemistry with practical business considerations, the company is positioned to help transform one of the world’s most polluting industries from the inside out.

The question isn’t whether the textile industry needs to change, but whether solutions like Everdye’s can scale quickly enough to address the urgent environmental challenges we face. With technology this promising and practical, the future of fashion might finally be looking a whole lot greener.
