@CelloMomOnCars Crud. I thought it was a biological compound.
That said, my mum showed me some interesting things lately: detergent sheets that looked like thicker paper. Put one in with the laundry it worked the same way as one if those pods.
Unfortunately seems to be a German thing so far.
@kyonshi
I need to look into those but multiple commenters to this post mentioned that the "resin" holding the sheets together is also plastic.
