Project summary

The BIOSCREEN project aims to develop sun-protection fabric made of bio-based materials.
Sun-protection is readily used to block unwanted sun radiation through windows. Products like these are generally made of a woven fabric and reinforced with a coating. The fabric often consists of  oil-based  products  with  limited possibilities for recycling. Bio-based polymers are readily available but are not used frequently for textiles.
In this project, materials and production processes will be developed to make fully bio-based sun-protection fabrics. The key is to maintain a high tensile strength upon ageing. The yarns will be woven into a fabric which will be coated with a novel bio-based coating.
Fabrics for sun-protection made in this way will be very interesting from an environmental point of view, as they will be made fully of bio-based products which means they will be quite easy to recycle or compost.

Impact and Vision

  • Market Impact
    Screens: installers are eager to integrate bio-based screens. They are often asked for green products. We expect that the first bio-based screens will be on the market short after project ends.
    Coatings: The developed formulations will be used by CALCUTTA for realising the bioscreen. The novel  formulations of ORGANOCLICK will be of interest to other textile companies. They will be ready to enter the market at project end.
  • Environmental Impact
    The aim of the project is to reduce the environmental burden from screens. The reduction of climate change from substituting fossil  to biopolymers is considerable - potential reduction of net emission of carbon to the atmosphere is estimated to a reduction of  50kTon CO2eq/year.
  • Social impact
    Employment: the project itself will create more than new 100 jobs.
    Consumer behavior: via BIOSCREEN we will promote the use of bio-based products.
    Labor circumstances and health effects: reduced export of unhealthy processes and contribute to a healthier indoor environment.


Pascal Scheldeman, Calcutta – “ECO-INNOVERA is important because it breaks down barriers for cooperation between European companies and research centers to start sustainable developments. It helps our companies to maintain a lead against the new economies and also offers them the opportunity to export the acquired knowledge to these countries so that the global ecological footprint as a result of the growing number of consumers can be hand held.
The contributions are rather limited compared to what is needed for such developments. Instead of subsidizing supposedly green energy generation systems - which are mainly produced outside of Europe - more resources should be foreseen by the EU to support initiatives like Eco Innovera”.
