> The technique involves heating ordinary plastics such as bottles or shopping bags and then putting them into an ordinary cotton candy machine (also known as a candy floss machine). The machine spins the plastic into a material that is similar to cotton candy (a mesh), which is also electrocharged by the spinning.

I'm always sceptical of these kind upcycling plastic narratives that involve melting them, since apparently a lot of plastics only are labeld safe under the assumption that they don't get heated until the melting point. After that they may start leaking chemicals, a bit like the whole non-stick coating story.

But if the source of plastic is reliable then this sounds pretty good.
