As far as I heard paper can’t be recycled because the fiber gets shorter every turn. It can be respiralled until it’s worthless pulp.

Eg:

> Fiber cannot, however, be recycled endlessly. It is generally accepted that a fiber can be used five to seven times before it becomes too short (as a result of repulping and other handling) to be useable in new paper products.

I thought the same about glass but that turns out to be genuinely endlessly recyclable. Good to know!

It’s a very big different between “can’t be recycled” and “can’t be recycled endlessly”. If the fibers can be used 5 times, it means that we can reduce the numbers of trees that have to be chopped down by 80%.
Having spent two years working for a paper company, marketing had a lot of work trying to get rid of the public perception that recycled paper is good. It takes a lot more energy to deink and treat recycled paper than manufacturing from fresh fiber.
