PCC improves the optical properties of paper and decreases the amount of pulp needed to make paper, subsequently reducing the number of trees needed.

Kraft process - Wikipedia

The kraft process (so called because of the superior strength of the resulting paper, from the German word Kraft for 'strength') was invented by Carl F. Dahl in 1879 in Danzig, Prussia, Germany. U.S. Patent 296,935 was issued in 1884, and a pulp mill using this technology started (in Sweden) in 1890.
