YES. paper can actually be recycled about six times before its fibres become too short. Recycled paper is often mixed with new paper to get a better quality.

Several correct answers here in that 6 times is about the maximum before the fibres become too short to bond.
But recycling paper is not as good an idea as it seems. Firstly there is a certain amount of extra energy used in collecting and transporting it. Then energy is used in the recycling process. There is a limit at present as to how recycled paper can be used meaning that a lot is actually exported involving more energy use and carbon emissions.
Finally and probably far more importantly - trees grown to produce wood pulp for manufacturing paper produce a huge volume of oxygen whilst consuming a large amount of carbon. This is particularly true of young trees. If the trees are cut down for paper this cycle continues to the benefit of the earth. If they are allowed to grow old the cycle actually tilts the wrong way and as they age they consume less oxygen and produce more carbon!
It is therefore very important to evaluate both sides of recycling and wood pulp use as too much recycling could end up doing more harm than good!

Yes. But , not a hundred times.
Everytime you recycle , you cut the fibre until it gets uselessly short (at about the 3rd , 4th and 5th pass) you then make it into a duplex testliner and that gets sold to the 2nd and 3rd Worlds.
When you tear a kraft and see 2 pulps , that's duplex ,, where the "backing" kraft is quite useless ,, that's testliner. An industrial lingo.
These papers are GSM(gramme square meter) designated usually in the weights 95 , 112 , 120 , 125 , 150
While good pulps ,, in simplex ,, are in weights 80 , 90 , 105 , 115 depending on region.
55 GSM is almost always good pulp.
Laboratory experiments are not in the high shear loads , of the actual line machines. And the actual pulp is usually very dirty.
The quality indicator in GSM weight has no system , you just have to remember which is which ,, but, that 70 GSM is the roller friction limit. To go thinner is high technology.

Yes as it is constantly being mixed with other paper. Most newspapers etc still use a small percentage of non-recycled paper in their mix.

is this guy for real? too much recycling? what about all the old growth forests that give their lives so we can have heavy furniture? and fast burgers? there's enough tree chopping in the world.

Yeh, it can be recycled hundreds of times. It just gets cleaned and then re-formed.

yes of course. each time its recycled it gets pulped scrubbed bleached and remade.
