Research and industry collaboration develops circular economy options for retired wind turbine blades

Project Overview

By 2030, Renewable Energy Sources, and its infrastructures, are expected to increase by 40% in Europe. Wind energy is one of the most popular and applicable source.

The repowering in the wind energy sector brings an enormous waste stream of end-of-life wind blades. Today, these blades are being deposited directly in landfills, with no circular options available in the market.

The aim of BLADES2BUILD is to improve and support circularity options of end-of-life wind blades by exploring three different circular stages:

  • Direct re-use of the EOL wind blades with minimal refurbishment or processing.
  • Re-purpose of individual materials constituents of the blades (and manufacturing waste).
  • Recycling the blade and glass fibre textiles scraps from the wind blade manufacturing in cement/clinker co-processing as an alternative fuel.
The Concept
The Blades2Build Concept



Identify, categorize materials, and create a flexible recycling road-map for EoL wind blades



Test EoL wind blades for downstream processes recycling/ repurposing/ reuse



Develop circular construction materials with materials produced from recycling & repurposing routes



Achieve all sustainability, engineering and financial requirements to initiate the large-scale demonstration plant



Demonstrate at TRL7 the pre-treatment of EoL wind blades to be used downstream in recycling & repurposing



Develop a virtual Hub to facilitate knowledge exchange and promote circularity within the wind energy sector and others

Expected Impact


BLADES2BUILD aims to transform wind power into a circular, zero-waste energy production enterprise.

  • 70% reduction of waste production by 2030

  • Zero-waste by 2050


BLADES2BUILD stems from the need to make the wind energy industry sustainable in its resource consumption/disposal efficiency.

  • 90% decrease of landfill disposal by 2030

  • 100% decrease by 2050


BLADES2BUILD demonstrates at TRL7 a circular solution for end-of-life blades in Southern Europe, providing the first recycling station for Spain and local revenue prospect growth of at least 5%.

Advisory Board

Prof. Matthieu Vandamme

Vice-head of the Civil Engineering & Construction department at Ecole des Ponts ParisTech

Engineer from Ecole des Ponts ParisTech and from Ecole Polytechnique (Paris, France), Matthieu Vandamme obtained his Ph.D. in civil engineering from MIT (Cambridge, MA) in 2008. Since then, he works as researcher at École des Ponts ParisTech in Laboratoire Navier (École des Ponts ParisTech, Université Gustave Eiffel, CNRS), where he focuses on building materials and poromechanics. He will support the project through his knowledge of the mechanics of building materials from the smallest scales.

Dr. Thierry Sedran

Head of “Materials for Transportation Infrastructures“ Laboratory in Gustave Eiffel University, Nantes Campus, France

Thierry Sedran has been a research engineer at University Gustave Eiffel (formerly Ifsttar, formerly LCPC) in France, since 1998. He is a specialist of concrete mix design and innovative applications  of cement-based materials in pavements. Part of his research is dedicated to recycling waste in concrete (e.g. reclaimed asphalt pavement or crushed concrete aggregates) which is in direct link with the BLADES2BUILD project.
