I've heard that a TP factory is a sight to behold, in order to turn out the fluffy product we knead so well, a large constant influx of water and wood is required. Apparently the factory that does it is the size of a Manhattan Project complex, and quite modern and automated.
And on the nether side of it is the usability of TP made from recycled products, which is apparently a much less user-friendly product.

It reminds me of the letter I received from my brother long ago, it appeared to be written on what we called 'math paper' in school, a smooth writing surface, with no absorbency to speak of. The last sentence of my bro's screed:

"This is written on Russian toilet paper"
