One Million Liters invites users from all over the world to join the revolution of sustainable denim by participating in the contest to donate a million liters of water to a good cause. 

23 Oct, 2019

  • With our pioneering Dry Indigo® technology, it is now possible to use 0% water in the indigo dye process. This is a real milestone in the textile industry.
  • The campaign invites users from around the world to join the “sustainable denim revolution” by taking part in a competition to donate a million litres of water to a good cause.

One Million Liters initiative has been launched today as part of the opening of KingPins Show in Amsterdam, which is one of the most important global events in denim. The campaign’s core mission is to show how changing one part of the production or manufacturing process can speed up change towards a more sustainable textile industry.


As a result of implementing DryIndigo® technology in 2019, Tejidos Royo has saved more than 1 million litres of water used in denim dyeing. The economic contribution from the first million litters saved has been donated to UNICEF, for its water and sanitation programmes which improve the lives of thousands of children around the world.

The aim for 2020 is to raise awareness among industry players and consumers by inviting them to select the cause they want to donate the next million litres of water to. Using the platform and the main social networks (Twitter, Facebook, Instagram and LinkedIn), the call for participation will spread over Europe and the United States. Users can send their suggestions of which cause would benefit the most from a million litres of water.

The recipient of the donation will be selected from the projects that are proposed across all campaign platforms before 30 November 2019. In December, the winning proposal will be revealed and, in February 2020, the million litres of water will be transported to their destination.


The textile industry and water consumption: the denim footprint

Reports by UNCTAD (United Nations Conference on Trade and Development) indicate that the fashion sector uses a quantity of water that would meet the needs of 5 million people every year. Likewise, producing a pair of jeans using the conventional system uses an amount of water equivalent to what one person could drink over seven years. Therefore, it is of prime importance to develop technologies that reduce this level of consumption, both for brands and for customers who are committed to sustainability and the environment.

Dry Indigo® is one of the new technologies that is revolutionising the sector. It uses 0% water in the dyeing process. It also reduces energy consumption by 65% during manufacture, uses 89% less chemical products, and completely eliminates waste water discharge.



José Rafael Royo explained “In the textile industry, we need to rework our processes to become a much more sustainable industry. DryIndigo® is a major milestone in this area, and we hope that it inspires both the sector and the brands to develop more technologies that contribute to making our industry a much more responsible one towards our surroundings. We are facing the sustainable denim revolution and, with One Million Liters, we want everyone to take part in it so that, together, we can meet the United Nations Sustainable Development Goals before 2030.” 


KingPins Amsterdam is undoubtedly the ideal platform to launch this pioneering campaign. The initiative’s presentation has bring together the key figures in the sector. Together, One Million Liters and DryIndigo® technology are set to form a watershed moment, both in the industry itself and in consumer awareness.

About DryIndigo®

As part of the company's claim – Textiles with values – and following 10 years of research, the Spanish textile manufacturer Tejidos Royo has collaborated with Gaston Systems Inc. and Indigo Mill Designs (IMD) to develop a revolutionary indigo dyeing process, resulting in the DryIndigo® technology. This unique dyeing process dyes with indigo, but without water, in a very small space. This dramatically reduces its environmental impact and everything that entails, but DryIndigo® also offers the great benefit of fully respecting the main characteristic of traditional denim: its colour.
