the production of the blade and how they are separating from the blade. to do that, it needs to be soaked in a big bath of mild acetic acid. after a few hours at 80 celsius, you get the result you see here. so it's just like vinegar in a supermarket? exactly. exactly like you would make pickles or descale your coffee pot. i can actually smell that. there is a scent of vinegar coming from the blade. this won't tackle today's waste, but when these blades retire, the materials could go into making other things. we could be furniture, suitcases, you can use it for surfboard manufacture, etc. so general consumer goods. but not new turbines? not as it is right now, but i'm never going to say never. and that's it for our round up of some of the latest sustainability stories. hope you've enjoyed them. from sweden and me and my electric ferry,
