Talk:Wood-pulp paper

19th Century Wood-pulp paper Recycling
When it comes to the establishment of paper mills, the first paper mills in Europe began production in the early 12th century in Spain, and spread to Italy by the 14th Century. The first groundwood paper mill in the United States was established in 1867 in Massachusetts. The information that is lacking is whether or not these paper mills recycled. It is assumed that linen was continuously recycled because of its limited availabily, but it cannot be assumed with such a degree of confidence that paper made from trees, which were considered a seemingly unlimited resource, were routinely recycled.

Were wood-pulp books routinely returned or sold to publishers or paper manufacturers for recycling? If these materials were returned to publishers, who returned them? Was the material returned by upper-class citizens, lower-class citizens, or private book dealers? Or was the recycling of paper solely paper manufacturers reusing their own unusable products? Or were publishers recycling their misprinted sheets, loose leaves, bulk scraps bought from printers, and mass-produced unwanted, unsold reading material and writing material?

ISO 9706 does not include specifications for the lignin content of paper because it is no longer universally accepted that lignin causes degradation of paper. It is well established that it causes yellowing. http://www.ifla.org/IV/ifla64/045-114e.htm (see the section on the impact of lignin) Therefore, I have taken out the mentions of degradation in the section on lignin.
