An unexpected way to upcycle: Plastic waste transforms into soap

It's often hard for me to intuitively wrap my head around the transformative nature of chemistry, the way that you can take one material or substance and change it into one that has entirely different properties really does seem like a kind of magic sometimes.

It's an interesting innovation if it can be scaled safely and sustainably. My understanding is that some surfactants (the product of the heating method here) can be toxic and not very environmentally friendly, hopefully this recycling method is not just kicking the can down the road on that sense.
