Most interesting. The implications for recycling fibreglass in general is even more interesting. I live on the coast and the number of derelict boats I see is huge - the number I don’t see is probably much higher. The main reason they have been abandoned is no one knows what to do with them other than burial.

Great video that sheds light on solutions to recycle turbines... And more importantly, that turbines are a small percentage of fiberglass waste. In a sense, it's a blessing that so much attention was brought on turbines blades because now a solution is developed that would treat a larger problem.

Wow it is amazing how many potentially groundbreaking technologies are springing up all the time! The more we can extract value from waste materials the better! I would be interested to hear your thoughts on small scale distributed wind vs large wind farms, and why people are putting solar panels but not wind turbines on their roofs? I know there is lower efficiency, more turbulence, slower speeds and a whole host of other problems but there seems to be little interest in overcoming them. Cheers and keep up the amazing work!

Wow, you're reading my mind! I will touch on the issue of small wind turbines in a short video later this week, and then delve into it further in a long video in a few weeks. It's basically because of the reasons you say, I'll make sure to include which aspects can be changed, and which can't. There is an interesting mid-sized turbine manufacture whose business plan is all about distributed generation. I had planned a site visit and interview a couple of weeks ago but it was delayed. I hope we will be able to reschedule soon though 😀 And yep, I agree that all of a sudden we are seeing heaps of potential solutions to waste problems. As Ryan mentioned in the video, over the last few years a real change has occurred in the way people think about these sorts of issues. It's not just for hippies any more!

It's great that a way to recycle wind turbine blade has been perfected. In the future most electricity will be generated by thorium reactors. Water including salt water will be used to power vehicles, airplanes, locomotives, and ships. Water converted to combustible gas to run generators will be much cheaper and less environmental damaging than wind turbines or solar panels.

Syngas can be catalyzed into whichever hydrocarbon you want. Not just fuel. You can make virgin plastic, use it, pyrolyze it, make new plastic, closing the loop. Using renewables to heat the process instead of burning some of the material for fuel lets you keep all the hydrocarbons. The waste heat can be sold to district heating or whatever, carbon free. When renewables and recycling mature, so many synergies will emerge that nobody thought of yet.

What do you think about adding a recycling fee? (not just for windmills) That would be returned with interest, to any recycler or reuser doing it in a green manner. For example this process would get a partial return, since there is still is pollution produced. With the remaining balance going to a pollution mitigation fund. The breakdown of how much of the recycling fee plus interest goes where should be keep fairly simple such as by the the net weight and or value retained or on how much pollution the recycling cause.

Yes, I am a big bird lover too. My favourite eagle is the wedge tailed eagle (Australian), and I would not want to see harm come to them. And you are right, every technology including wind energy has downsides. I will make a video on birds and wind turbines next year, but just quickly, here are the main facts: Old wind turbines that had lattice towers used to kill a not-insignificant number of birds. They would roost in the tower, and then take off into the blades. This doesn't happen any more, since the towers are monopoles. Buildings, cars, cats and climate change all kill vastly more birds than wind turbines. But some specific birds in some specific locations do have problems seeing and avoiding turbines. I believe there are some raptors in California for example, and probably others. Bats also have problems in some areas. There is ongoing research on how to reduce this, but until we find a perfect solution we'll need to keep doing environmental impact assessments that include birds. We just shouldn't put wind farms in places where they are going to cause problems with birds (most countries have good regulations to ensure this doesn't happen). There aren't that many places where it is a problem, so it's actually not a really big deal to help the birds out in this way. Thanks for watching, and thanks for the comment.

It takes more fuel to make ethanol than what is produced. No doubt that's the case here. List the fuel sources? Not to mention the energy and consumables it takes to process these into smaller pieces. What inert gas would be used and what's the process of obtaining it? Sometimes we need to take a beating, learn our lesson, deal with consequences, start fresh and come up with a better idea for moving on. We have loads of data on failure points on these blades. I think a better idea would be to reinforce what we have before they reach the point of potential failure or inefficiency. Design retrofit kits. Design new one's that are rebuildable. Nothing lasts forever but if you can double or triple life expectancy then you have 1/2 to 1/3 of the spent materials to deal with.
