  • Abstract and objectives: REWIND aims to develop and validate an on-site recycling technology for wind turbine blades, avoiding transport to centralised recycling plants and incorporating recovered glass and carbon fibres into concrete production. The project proposes modular equipment that can be rapidly installed and dismantled at wind farms, supporting a circular approach to composite waste management. The methodology combines mechanical size reduction into 20–50 cm pieces with microwave-assisted solvolysis using green chemical agents to depolymerise epoxy resins. This hybrid process targets a 57% reduction in reaction time while recovering fibres for reuse. Expected benefits include reductions of up to 50% in wind industry waste, 30% in environmental impacts during composite processing, and 30% in operating costs for wind recovery projects. The proposal also targets avoided emissions of 10,000 tonnes of CO₂ annually through on-site processing and a 10% reduction in concrete industry CO₂ emissions when recycled fibres are incorporated into mixes.EOLCOM will construct the final demonstrator, while COPSA will industrialise concrete mixes containing recovered fibres. I2CON and the University of Burgos will develop the recycling methodology and concrete formulations at laboratory scale. REWIND supports circular economy objectives, the European Green Deal, and sustainable industrial innovation by connecting wind energy waste with construction applications.
