The LIFE REFIBRE project transforms disused wind turbine blades into glass fibers that, once added to asphalt, make roads up to 30% more durable.

93.6% of the electricity demand in Castilla y León is covered with energy that comes from the wind. According to the latest data from the Wind Business Association, our community is the one with the largest installed wind power. Spain, for its part, is the fifth power in the world and the second in Europe in energy generated through windmills or wind turbines. We have 1,298 wind farms and a total of 21,574 wind turbines. But what happens to the blades of these mills when they reach their useful life? They have probably never wondered, however, its management represents an environmental problem of more than 220,000 tons that will end up becoming waste accumulated in landfills.

It is an issue that was already worrying the sector and that, by chance, Jorge de Blas, technical director of the construction company Blasgon, discovered: «we belong to an innovation group. We were going to meet, as usual, but I made a mistake and entered a meeting of a group of companies dedicated to the windmill sector, where they ended up raising this problem. At that moment I thought that this material inside a road surface could come in very handy”.

This is how the LIFE REFIBRE project arose, from the union of five entities: the Construction Institute of Castilla y León (ICCL), the CARTIF Technology Center, the engineering and consulting company Incosa and the construction companies Blasgon and San Gregorio. Together they have designed and built a system that transforms disused wind turbine blades into fiberglass that, once added to asphalt, makes roads up to 30% more durable. In this way, they have not only managed to give a second life to the huge blades of windmills, but also to improve the properties of the roads. The first test has been carried out on a stretch of road of just over a kilometer that connects the A-11 motorway with Toro.

A viable project thanks to EU funding

«We are SMEs in a sector that is tremendously mature and competitive, therefore, we have very limited resources to dedicate to innovation. If it hadn’t been for the EU funding, we wouldn’t have been able to move forward”, highlights Álvaro Oliver, managing director of San Gregorio.

Felipe Romero, technical director of the ICCL and coordinator of the project, details the process of applying for a financing program from the European Union. Why did you decide to apply for LIFE’s help?

In the first place, it offered us a decisive percentage of financing to ensure the viability of the project. Secondly, because the LIFE call is of a high level. Linking the idea of developing these new materials to the program was a guarantee of quality for us.

Has the support of the EU influenced your situation?

So much so that we are considering the creation of a company specifically intended for the commercial exploitation of the results of the project. It has been a complex process in itself, but at the same time very rewarding because we have learned a lot from each other. Having an institutionalized experience has made us see R+D+i in a different way and establish it within our culture. It has provided us with very relevant knowledge in order to achieve new projects.

How does the commitment to innovative projects like this benefit Castilla y León?

It is very important for the region to develop a network of companies that are at the forefront of each of its activities and that help, in turn, to attract EU resources. Therefore, it is a fundamental commitment so that the projects remain in the region, helping, among other things, to retain talent.
