Wind energy has been a cornerstone of Europe's energy transition for years, but it's not all good news. Beyond the visual impact on the landscape and bird collisions with the blades, the sector faces a growing problem: what to do with wind turbine blades once they reach the end of their lifespan. Now, a business consortium has proposed a solution that involves replacing traditional materials with wood, and Navarre has been chosen as the location for this industrial leap.
The Navarre region is poised to become the site of the world's first commercial factory dedicated to producing wind turbine blades from recycled wood. The project, named VB1F, is a joint venture between the German companies Voodin Blade Technology and Anker-Tec, and the Lithuanian firms VMG Wood Invest and VMG Technics. The planned investment is around €100 million, of which €48,18 million will come from the European Union's Innovation Fund. The plant, which could be operational by 2031, will create approximately 450 skilled jobs and manufacture up to 160 sets of blades per year, with lengths ranging from 20 to 90 meters.
An environmental problem that urgently needs to be solved
The reason for this commitment is not accidental. Conventional blades, made of fiberglass or carbon fiber bonded with epoxy resins, are very difficult to recycle. In fact, between 85% and 90% of a wind turbine's mass is already recovered (steel, copper, electronics), but the blades are the major obstacle. Their highly stable chemical bonds prevent the materials from being separated economically, so many end up in landfills after the turbine's 20-25 year lifespan.
The scale of the challenge is considerable. According to a study cited by WindEurope, the European industry association, more than 43 million tons of waste from retired wind turbine blades could accumulate worldwide by 2050. Some countries, such as Austria, Finland, Germany, and the Netherlands, have already banned burying them, but it remains common practice in the rest of Europe. The industry has voluntarily committed to stopping this practice, but there is no binding EU law preventing it, and the industry itself is calling for further action.
LVL wood as a real alternative
The consortium's proposed solution involves replacing composite materials with LVL (Laminated Veneer Lumber), a derivative of Nordic spruce wood manufactured by bonding thin layers with structural adhesives. This material offers mechanical strength and dimensional stability comparable to fiberglass, but with a key advantage: it is 100% recyclable at the end of its useful life.
The manufacturing process has also changed completely. Instead of using specific molds for each model, five-axis CNC machines machine the parts according to a digital file , reducing capital investment by around 54% and lowering the cost per blade by approximately 20%. According to Voodin Blade Technology, manufacturing with wood reduces COâ‚‚ emissions by 78% and allows for the storage of biogenic carbon throughout the blade's lifespan. The company estimates that, in its first decade, these blades could equip wind turbines capable of generating around 13,5 million MWh of electricity and prevent the emission of more than 2,4 million tons of COâ‚‚ equivalent.
Why Navarre and what remains to be verified
Navarre is not a random choice. The region has established itself as a leading wind energy hub in Europe, with a well-developed local supply chain, specialized logistics infrastructure, and decades of experience in the sector. Furthermore, institutional support has been key to attracting this investment, which reinforces the region's position as a center of innovation in renewable energy.
However, not everything is certain. The data on emissions and cost reductions comes from the companies themselves , not from an external audit, and the factory won't open until 2031, so there's still no real-world evidence of how these blades perform after 20 or 25 years of use. It also remains to be seen whether the wood comes from sustainably managed forests, an essential requirement for the environmental benefits to be genuine. And while the industry's commitment not to bury blades is a step forward, it's still voluntary, not a legal obligation across Europe.
However, the VB1F project represents a paradigm shift in the wind energy industry. It not only addresses the waste problem at its source, but also opens the door to a circular business model in which blades can be recovered and reused at the end of their useful life. The Navarre plant, with its €100 million investment and EU backing, will become a testing ground for a technology that could be replicated in other countries. The question is no longer whether the transition to recyclable materials will happen, but who will be ready to take advantage of it when it does.
