   As usual, very short sighted when ANY LEVEL of Government's are involved with ANYTHING, except matters of war, of course.

   A little too sensationalized for my tastes, they are rather simple solutions touted as incredible discoveries, but yeah I'm glad people are working on recycling.
   Anything, not just wind turbine blades.

   You couldn't make this up. The Danes are world leaders and winfarm engineering. I was informed by one such Viking of a man that they were damaging to the environment and highly inefficient. He used the word 'bollxcks.' This was 10 or more years ago. He said he shoulder complain, as after a lifetime of being a heavy engineer, working in the windfarm industry at the top of the tree, so to peak, was making him a grsat deal of money. He went on to say that they wouldn't last long and the recycling would be expensive. STOP PRESS; THE DANES ARE NOW WORLD LEADERS AT RECYCLING WINDFARMS. You really couldn't make this shxt up. Produce something uselss and then milk it again by becoming world leaders at getting rid of the crap that made you wealthy. 🤣👍

   I was informed, at some length and in some detail, by a Danish wimdfarm engineer, that windfarms were making him and everyone involved with them, a great deal of money. He explained that as a source of clean energy for the future, they were next to usless and little more than a scam. His words not mine.

   if they are virtually indestructible then why replace them at all or just repair them

   So much chemicals used to produce and breakdown fiberglass,, is the wind turbine really worth saving our enviroment?? bit like the electric car problem with metal batteries. ????

   We have some half solutions to use these retired blades in cement production or Repurpose them in bridge construction, furnitures, electric transmission poles, and playground equipment but the amount of these retired blades in future will be much more and we can't just accommodate them in just Repurposing solutions that's why we need complete recycling solutions and i am happy that Vestas and Siemens Gamesa are making great progress to make this reality.

    How does the blade waste compare to global CO2 emissions? (4000,000,000 tonnes per year) BBC please highlight both sides of the story as you’re at risk of becoming increasingly biased towards anti-eco!

    Just out of interest does anyone know what happens to the acidic solution after the blade has been in there? Thanks

    Millions of birds die under these blade's, maybe the solution is finding a different wind design, a tower of vertical blades , made of recycled plastics or wood

    all energy-producing machinery must be fabricated from materials extracted from the earth. No energy system, in short, is actually “renewable,” since all machines require the continual mining and processing of millions of tons of primary materials and the disposal of hardware that inevitably wears out. Compared with hydrocarbons, green machines entail, on average, a 10-fold increase in the quantities of materials extracted and processed to produce the same amount of energy. For a snapshot of what all this points to regarding the total materials footprint of the green energy path, consider the supply chain for an electric car battery. A single battery providing a useful driving range weighs about 1,000 pounds. Providing the refined minerals needed to fabricate a single EV battery requires the mining, moving, and processing of more than 500,000 pounds of materials somewhere on the planet . That’s 20 times more than the 25,000 pounds of petroleum that an internal combustion engine uses over the life of a car. Among the material realities of green energy:

    Building wind turbines and solar panels to generate electricity, as well as batteries to fuel electric vehicles, requires, on average, more than 10 times the quantity of materials, compared with building machines using hydrocarbons to deliver the same amount of energy to society.

    A single electric car contains more cobalt than 1,000 smartphone batteries; the blades on a single wind turbine have more plastic than 5 million smartphones; and a solar array that can power one data center uses more glass than 50 million phones.

    Replacing hydrocarbons with green machines under current plans—never mind aspirations for far greater expansion—will vastly increase the mining of various critical minerals around the world. For example, a single electric car battery weighing 1,000 pounds requires extracting and processing some 500,000 pounds of materials. Averaged over a battery’s life, each mile of driving an electric car “consumes” five pounds of earth. Using an internal combustion engine consumes about 0.2 pounds of liquids per mile.

    Oil, natural gas, and coal are needed to produce the concrete, steel, plastics, and purified minerals used to build green machines. The energy equivalent of 100 barrels of oil is used in the processes to fabricate a single battery that can store the equivalent of one barrel of oil.

    By 2050, with current plans, the quantity of worn-out solar panels—much of it nonrecyclable—will constitute double the tonnage of all today’s global plastic waste, along with over 3 million tons per year of unrecyclable plastics from worn-out wind turbine blades. By 2030, more than 10 million tons per year of batteries will become garbage.

    The extraction process of lithium is very resource demanding and specifically uses a lot of water in the extraction process. It is estimated that 500,000 gallons of water is used to mine one metric ton of lithium. With the world's leading country in production of lithium being Chile,  the lithium mines are in rural areas with an extremely diverse ecosystem.

    In Chile’s Salar de Atacama, one of the driest places on earth, about 65% of the water is used to mine lithium; leaving many of the local farmers and members of the community to find water elsewhere. Along with physical implications on the environment, working conditions can violate the standards of sustainable development goals.

    Additionally, it is common for locals to be in conflict with the surrounding lithium mines. There have been many accounts of dead animals and ruined farms in the surrounding areas of many of these mines. In Tagong, a small town in Garzê Tibetan Autonomous Prefecture China, there are records of dead fish and large animals floating down some of the rivers near the Tibetan mines.

    After further investigation, researchers found that this may have been caused by leakage of evaporation pools that sit for months and sometimes even years. Lithium-ion batteries contain metals such as cobalt, nickel, and manganese, which are toxic and can contaminate water supplies and ecosystems if they leach out of landfills. Additionally, fires in landfills or battery-recycling facilities have been attributed to inappropriate disposal of lithium-ion batteries. As a result, some jurisdictions require lithium-ion batteries to be recycled. In spite of the environmental cost of improper disposal of lithium-ion batteries, the rate of recycling is still relatively low, as recycling processes remain costly and immature. More than 400 million batteries are used throughout the country, with only 5% being recycled, resulting in 8000 tonnes ending up in landfill.

    Creating the lithium-ion battery pack is also more environmentally harmful than the manufacturing process for an average petrol-powered car.

    Glad to know it is going to be simple chemistry of acetic acid. Acetates of so many things are very soluble in water, and acetic acid can easily be made from plants. The scaling up of recyling will therefore be commercial problems rather than technical or environmental problems. As Demark is the pioneering tiny country to adopt wind turbines on a large scale, they have a head start and an urgent need in developing ways to recycle turbines.

    A merry-go-round of ship sails would be far easier to fabricate, maintain and recycle. Not only that, but bird strikes would be non-existent. The only reason to keep pushing windmills is to line already overflowing corporate pockets. They make more money on problems than solutions.

    Why they don't just make the blades from aluminum like they used to do with aircraft wings? Much easier to recycle aluminum parts.

    Nice news segment about Norwegian wind power…. what happened to British news? How many of these videos are about the UK? I see more news about the UK on DW, France 24, and TVP than here on the BBC channel…

    (1) what idiot built "sustainable" tech that is NOT recyclable? (2) what idiot designed this kind of tech with such a brief useful lifespan? (3) why can't such workpieces be "permanent" (and not need replacing)? (4) why aren't we using more wind power? After the initial investment, it's basically free energy…

    Are they Green really? Well the amount of concrete in the foundations is massive . Now remember this is the very reason dams are not green power yet in all the countries now running wind they have used more concrete than all the dams in the world. Sound untrue? A dam lasts 100yrs plus makes more power and can be almost fully recycled Wind cant come close to that as their looking at 20-25yrs

    Could cut the blades shorter and use re-use them on smaller turbines? 😮🇬🇧🌈👍♥️
