The expected results from the LIFE-ECOTEX Project are

  • To demonstrate the circular economy concept by avoiding the landfilling of 750 kg of textile wastes from footwear industry and recycling them chemically by means of catalytic glycolysis.
  • To manufacture 800 kg of new textile products based on polyester fibres with textile grade which have been recycled chemically:
    • ECOTEX non-woven felts
    • ECOTEX non-woven insoles from 650 to 800 g/m2
    • ECOTEX non-woven isolation panels with 1.500 g/m2 and 60 mm of thickness
  • To reduce the GHG emissions, estimated around 1.47 t CO2 eq /t PET produced.
  • Proposal and/or recommendations for environmental policies authorities regarding the use of chemically recycled polyester in the textile manufacturing.
  • Replicability and transferability study for the developed chemical recycling process.
  • Dissemination activities such as workshops, newsletters, scientific articles, etc.

Main Results Obtained in the Project

  • The demonstration of a feasible circular economy concept for the footwear sector based on the chemical recycling process of PET textile wastes generated in that industry, avoiding landfilling 750kg of PET textiles waste.
  • Products manufactured with chemical recycled PET:
    • Non-woven textiles (Felts): 650-800 g/m2 for insoles and 1,500 g/m2 for insulators.

    • Shoe insoles: 130 insoles (No. 37), 130 insoles (No. 42) and 130 insoles for children.

    • Insulation panels: 12 panels (2,000 g/m2, 60 mm thick) + 12 panels (1,500 g/m2, 40 mm thick).

  • The carbon footprint of the chemical recycled PET pellets was reduced in 1.04 t CO2 eq/ t PET produced.
  • Replicability and transferability study of the LIFE-ECOTEX chemical recycling process in other European countries, sectors and/or applications.
  • Recommendations to environmental policies authorities regarding the use of chemically recycled polyester and promotion amongst stakeholders.
  • Dissemination activities to communicate the project´s objectives and results (attendance to congresses and fairs, promotional materials, articles and press releases, networking).
