General information
- Short Summary
- A Spanish Construction R&D Centre is currently leading the technical development of a EUROSTARS proposal for the development of 3D-printed geotextiles and geocells made from recycled rubber and HDPE/PP, designed to reinforce weak soils or CDW-based fills, enabling the deployment of an innovative, sustainable, and efficient permeable pavement system with no leaching or clogging. The consortium is seeking a geotextile/geocell manufacturing company, or a CDW valorisation specialist
- Full Description
-
A Spanish Technological Centre specialized in Sustainable Construction and Smart & Resilient Infrastructures, with extensive experience in coordinating and participating in European projects, is currently leading the technical development of a EUROSTARS proposal for the project “FLEXROAD 3D”, contributing its expertise in sustainable pavements and field testing. The consortium is leading by a Spanish SME specialised in the recycling of end-of-life tyres (ELTs).
The FLEXROAD 3D objective is to design and validate ultra-thin geotextiles and geocells manufactured via 3D printing from recycled ELT rubber blended with secondary plastics (HDPE/PP). These elements will reinforce low-bearing soils or fillings made from construction and demolition waste (CDW), facilitating the installation of the highly permeable FLEXROAD flexible pavement.
The project aims to develop solutions that:
• Contain over 70 % recycled materials,
• Reduce the use of virgin raw materials and CO₂ footprint by at least 30 % compared to conventional alternatives,
• Ensure environmental safety (no leaching or clogging).
Laboratory and pilot-scale testing will be carried out.
The consortium is looking to incorporate a geotextile or geocell manufacturing company, or alternatively a company specialised in CDW valorisation, interested in scaling up the solution or supplying/validating recycled infill materials. The supply of recycled rubber is already secured by the SME leader of the proposal.
The partners should be in eligible countries.
Programme call: Eurostars 3 – Call 6 (2025)
Fields of expertise: civil engineering, additive manufacturing, circular economy, geotechnics, road construction, pilot testing.
Timescales:
- Official call deadline: 4th september 2025
- Expression of Interest Deadline: 1st september 2025 - Advantages and Innovations
-
FLEXROAD 3D introduces 3D-printed geotextiles and geocells from recycled tyre rubber and HDPE/PP, enabling permeable pavements over poor soils or CDW fills. It offers a circular, low-carbon alternative to conventional soil reinforcement.
Key benefits:
• >70% recycled content, ≥30% CO₂ and raw material reduction
• Customisable geometry for ≤5 cm thickness and strong performance
• No leaching/clogging, ensuring environmental safety
• Promotes reuse of CDW and marginal soils
• Supports affordable, sustainable roads and industrial symbiosis. - Technical Specification or Expertise Sought
-
Option 1 – Geotextile or geocell manufacturing company:
• Experience in the production of geosynthetics (geotextiles, geocells, or similar products).
• Knowledge of polymer processing techniques such as extrusion, moulding or preferably 3D printing, especially using HDPE, PP or recycled materials.
• Ability to collaborate in the development and validation of innovative geosynthetic products in pilot settings.
• Interest in scaling up recycled-material solutions, particularly those involving ELT rubber.
Option 2 – Company specialised in CDW (construction and demolition waste) and valorisation:
• Experience in the treatment, classification, and reuse of CDW as backfill or construction materials.
• Knowledge of technical requirements and regulations for CDW use in civil or road works.
• Capability to co-develop and supply sustainable infill mixtures based on CDW or other industrial residues (e.g. diatomaceous waste).
• Willingness to participate in pilot-scale infrastructure validation under circular economy criteria. - Stage of Development
