The quantity of chemicals is drastically reduced, while faster dyeing cycles lead to a major drop in energy consumption. The use of water is cut to near-zero, sharply diminishing pollution. Two are American enterprises - AirDye and ColorZen - and the third is a Dutch company, DyeCoo, whose process is being used by Adidas, one of its partners.Īlthough the three processes are very different from each other, the results are much the same. In recent years, three companies have developed largely waterless dyeing technologies. Now, new waterless dyeing technologies are being developed and deployed that could help reduce the vast quantities of pollution generated by textile dyeing.
The industry in question? The textile-dyeing sector, whose colorful products belie the reality that it is an egregious polluter, especially in China, which by some estimates produces - and then discharges - roughly 40 percent of all dyeing chemicals worldwide. The wastewater from that industry is then dumped, often untreated, into rivers that bring its toxic content to the sea, where it spreads around the globe.
Each year, one global industry gulps down trillions of liters of fresh water, together with massive amounts of chemicals.
