If you want to know how your “normal” paper breaks down, stick a few sheets in a bottle, fill with water, shake and leave stand for a few hours. Give it another shake and see what you reckon. Seen a video a few years back with a few different super market brands and the expensive porta loo stuff and there was no difference, except price. Oh, I think the recycled stuff made out of, and feeling like, tree bark, was a bit slower to break down.
