Another US firm, AirDye, insists its technology uses a sliver of the water and energy compared to traditional dyeing processes, and has several niche designers and manufacturers as customers.

Other than nebulous talk about partnering with NGOs to reduce water consumption, few large companies currently consider new waterless or near-waterless technologies. One that does is Adidas. The CO2, which takes on liquid-like properties, is contained in stainless steel chambers. After the dyeing cycle the CO2 becomes gasified, and dye within the cotton fibres condenses as it separates from the gas.

The CO2 is then recycled and pumped back into the dyeing vessel. Adidas claims using CO2 is a safe and environmentally-friendly option because the gas is contained and can be used repeatedly without the risk of any emissions.

Although dyeing using compressed CO2 has existed for over 25 years, Adidas claims a supplier in Thailand operates the only factory with the ability to scale this technology. So can this process transform the textile industry?
