A groundbreaking digital dyeing process aims to tackle the apparel industry's significant environmental impact.
In a small rural area of Taiwan, among various dye houses, Alchemie Technology is nearing the launch of a project that could revolutionize the apparel industry and significantly lower its environmental impact. The UK-based startup has focused on the notoriously polluting dyeing process, unveiling what it claims to be the world’s first digital dyeing technology.
“Traditional fabric dyeing involves steeping the material in water at around 135 degrees Celsius for up to four hours, using gallons of water,” explains Alchemie founder Dr. Alan Hudd. He notes that to dye one ton of polyester, approximately 30 tons of polluted wastewater are generated. This conventional method, rooted in techniques established over 175 years ago in England's textile mills, has been exported globally, impacting ecosystems worldwide.
The World Resources Institute estimates that the textile industry consumes around five trillion liters of water annually for fabric dyeing, contributing to about 20% of global industrial water pollution and depleting crucial water resources in several regions. Additionally, this sector generates a considerable carbon footprint, accounting for nearly 10% of worldwide greenhouse gas emissions, as highlighted by the United Nations Environment Programme.
Alchemie’s technology, called Endeavour, introduces an efficient and eco-friendly dyeing process that compresses dyeing, drying, and fixing into a significantly shorter timeframe, all while conserving water. Using principles akin to inkjet printing, Endeavour utilizes 2,800 dispensers to release about 1.2 billion dye droplets per linear meter of fabric.
"We ensure precise placement of tiny dye droplets, allowing us to switch them on and off like a light switch," Dr. Hudd remarks. The process is projected to reduce water usage by 95%, energy consumption by up to 85%, and operate three to five times faster than traditional methods.
After developing the technology in Cambridge, Alchemie has moved its operations to Taiwan to assess Endeavour's effectiveness in a practical setting. Ryan Chen, Alchemie’s new chief of operations with a background in Taiwan's textile sector, emphasizes the necessity of moving to real factories for commercialization.
Alchemie’s innovation isn’t the only initiative striving towards reducing water usage in dyeing. China’s NTX has introduced a heatless dye technique that reportedly decreases water consumption by 90%, while Swedish startup Imogo employs a “digital spray application” with similar benefits.
Kirsi Niinimäki, a design professor at Aalto University in Finland, sees promise in these emerging technologies but encourages transparency regarding the fixing process and the long-term durability of fabrics.
Alchemie is focused on refining operations amid Taiwan's warmer, more humid climate conditions. For instance, service manager Matthew Avis discovered that Endeavour requires an air-conditioned space for optimal performance, a critical consideration for the region, where much textile manufacturing occurs.
Looking ahead, Alchemie has ambitious plans for 2025, intending to test Endeavour with cotton in South Asia and Portugal, while addressing how to scale its operations to meet the demands of major fashion retailers like Inditex, owner of Zara, whose suppliers require extensive fabric dyeing capabilities.
As Alchemie prepares to expand, the potential for significant environmental advancements in the fabric dyeing process stands on the horizon. These innovations could mark the beginning of a new era for the fashion industry, one that prioritizes sustainability and reduces harm to our planet.
