Insights

  • Portugal's University of Coimbra's DyeLoop project aims to make textile dyeing more sustainable by reusing dyes and reducing water and energy consumption.
  • Funded by the Calouste Gulbenkian Foundation, the project will recycle dye bath effluents and explore biotechnological solutions.
  • Over three years, it seeks to cut textile dyeing costs by over 50 per cent and minimise environmental impact.
The University of Coimbra (UC) is developing innovative technologies to make textile dyeing more cost-effective and sustainable. The project DyeLoop – Circular Technologies for Textile Dyeing, funded by the Calouste Gulbenkian Foundation, was officially presented on February 18. Focusing on sustainability in the textile sector, DyeLoop uses unique circular economy technologies to reuse dyes and significantly reduce water and energy consumption.

"This is a paradigm shift for the textile industry. After the dyeing process, instead of sending the wash water for treatment and disposal, DyeLoop recycles the dye bath effluents back into the process," explained Jorge Pereira, the project coordinator.

Over the next three years, the research team will also explore new biotechnological solutions for producing more sustainable textiles. "DyeLoop will enable the development and implementation of an industrial prototype, expected to reduce textile dyeing costs by more than 50 per cent," added Pereira, professor and researcher at the UC faculty of sciences and technology.

The project has proven to be an effective means of optimising essential resources and minimising environmental impact, aligning with the Sustainable Development Goals of the UN's 2030 agenda, UC said on its website.

The Calouste Gulbenkian Foundation has granted €1.4 million (~$1.47 million) to support this pioneering project. The funding agreement was officially signed at the project's launch ceremony, attended by the rector of the University of Coimbra, Amílcar Falcão, the president of the board of trustees of the Calouste Gulbenkian Foundation, António M Feijó, the executive trustee, António Cruz Serra, and the project coordinator, Jorge Pereira.
