Paper works up to 6 times at best, if someone is able to track the same batch. But recycling paper uses more energy than using virgin, and if virgin paper sourced from a sustainable place like Canada, then recycled paper is actually worse for the environment because of the energy thing and de-inking water waste. Also the timber is cut for housing actually and only the edges of the logs are used to make chips for making paper. So trees aren’t being cut solely for paper (from sustainable countries). Until we meet again (insert Skeletor running away)

Glass and plastic both require virgin material, else you’d get garbage out.

Everything I'm reading suggests the problem with glass recycling is contamination, and that once that's accounted for what's left over can be infinitely recycled without quality loss.
