The Sustainable Textile Processing project
In 2021, a team of DECATHLON method engineers launched the Sustainable Textile Processing project to assist the 30 production sites that consume the most energy, water and chemicals (25 in 2022).
Through this project, work is done on the supplier’s machines to optimise processes, and reduce water consumption and energy losses. Several highlights can be noted for 2023:
- Actions continue to improve dyeing processes for conventional polyester and cotton at seven suppliers representing 20% of DECATHLON’s textile purchase volumes, through experiments with new machines and technologies to reduce water consumption (salt-free dyeing that greatly reduces energy consumption during water treatment, supercritical CO2 dyeing (high pressure gas), tests on direct dye spraying on fabrics, ultrasonic washing, etc.)
- Meters are gradually being installed on machines of certain production lines to accurately measure water and energy consumption at every stage of the manufacturing process.
These meters were installed at fifteen production sites in 2023 (five in 2022), and have already improved the reliability of environmental data and the sites’ ability to take appropriate improvement actions in a virtuous cycle logic
- ECODYE internal certification was launched, including four criteria: water consumption, energy consumption, CO2 emissions and water recycling. Thanks to the measurements taken by the meters mentioned above, it is now possible to refine the thresholds for evaluating and selecting suppliers.
This year, the first ECODYE referenced DECATHLON is continuing its efforts to define certification criteria for all product families
In 2023, DECATHLON estimated that these actions avoided the emission of 30,000 tCO2e43 (45,000 tCO2e44 in 2022) and the consumption of 300,000 m3 of water (240,000 m3 in 2022), i.e. 2% of the impact of the company’s textile activity.
