End-of-life plan needed thousands of wind turbine blades
A new study led by The University of South Australia indicates tens of thousands of wind turbine blades will end up in landfill by the end of the decade unless end-of-life programs are established soon. The study, led by Professor Peter Majewski, highlights the challenges of recycling wind turbine blades, which are made of either carbon fibre or glass fibre composite material, both of which are expensive to break down, with the recovered materials having minimal market value. “The same features that make these blades cost-effective and reliable for use in commercial wind turbines make them very difficult to recycle in a cost-effective fashion,” Prof Majewski says. “As it is so expensive to recycle them, and the recovered materials are worth so little, it is not realistic to expect a market-based recycling solution to emerge, so policymakers need to step in now and plan what we’re going to do with all these blades that will come offline in the next few years.” In many parts of the world, wind turbine blades are currently dumped in landfill, but this practice has been banned in some European countries, and with estimates suggesting there will be more than 40 million tons of blade waste worldwide by 2050, alternative solutions are urgently being sought. Professor Majewski says that, while there is some very limited potential for reuse of blades in niche construction settings and a small market for some of the reclaimed materials, it is likely the costs of disposing of the blades in a sustainable fashion will need to be factored into their production and running costs. “Our research indicates the most likely viable option is a product stewardship or extended producer responsibility approach, where the cost of recycling the blades is factored into either the cost of their manufacture or the cost […]
