Netherlands seeks green solution for 10,000 obsolete wind turbines
Wind power does not only generate electricity: it also generates mountains of waste that cannot be recycled. The Netherlands faces the decommissioning of around 10,000 wind turbines whose life cycle has ended, built with multilayer composite materials that make their recycling extremely expensive and slow.
The dilemma is no small one: burying them would require space the country lacks, and exporting them to third countries with more land is emerging as the least bad solution. Meanwhile, thermal and chemical processes are being developed to recover the blades, though at costs few are willing to bear.
Lifespan: from 20 planned years to 30 in practice
The wind turbines installed between 2004 and 2008 had an estimated lifespan of two decades. The reality is that many turbines are extending their operation to 30 years, according to industry sources. A reprieve that delays the problem but does not solve it: the blades, made with resins and glass or carbon fibres, neither degrade nor recycle easily.
Burial, export or burning?
The options on the table are as varied as they are controversial. Some defend controlled landfill as an ecological solution, although land is scarce in the Netherlands. Others point to exporting to countries with more space, a practice reminiscent of ship breaking on beaches in the global south. And there is no shortage of those who suggest incineration, despite the associated emissions.
As the debate heats up, thermal and chemical recycling of the blades is advancing slowly. But costs remain the Achilles heel: turning a material designed to last decades into a usable resource costs a fortune.
The business behind sustainability
Behind the technical problem lies a multibillion-euro business. The utilities that installed these wind farms have already written off the turbines and now face the cost of dismantling them. Some industry sources point out that the actual lifespan has been extended ten years beyond what was planned, which has allowed profitability to be stretched. When the time comes to replace them, the cycle will start all over again: new wind turbines that, two decades from now, will generate exactly the same waste.
