CIRCUBLADE aims to develop a circular economic solution for the reuse of large quantities of end-of-life composite wind turbine blades in other applications with a focus on efficient logistics, design and manufacturing as well as the development of a digital tool that will contribute to circular solutions and resource efficiency.
The problem of how to take care of wind turbine blades after their lifetime remains and is growing. Since the installation of wind turbines took off in the 1990s and 2000s and the estimated lifetime is 20–25 years, the need for technical solutions for handling old blades is urgent in the face of the upcoming dismantling of these wind turbines. Wind turbine blades mainly consist of glass fiber composite, i.e. hard plastic (epoxy) reinforced with glass fibres. Dealing with of end-of-life wind turbine blades is today a sensitive issue, as 50% of the blades go to incineration and 50% to landfill. Today, there is no sustainable and economical solution for recycling epoxy-based GFRP. The aim of this project is to give a second life (minimum 40 years) to the wind turbine blades and give time to the knowledge to come up with a feasible and sustainable solution for thermoplastic GFRP.
The aim of the project is to develop a circular economic solution through the reuse of used wind turbine blades in new products (pedestrian- and cycle bridges and noise bareers) with a focus on efficient logistics, design and manufacturing as well as the development of a digital tool that will contribute to being able to achieve the the circular solution and resource efficiency.
The solutions developped in our project will mean climate/environmental benefit through the reuse of used wind turbine blades that today burden the environment (incineration and landfill) in new products/applications. The business benefit of the project's solutions will be demonstrated through developed sustainable business models with a strong connection to both short- and long-term market introductions of various products made from used blades.
