Papermaking starts where the pulping process leaves off

In theory, the closed mill perfectly balances all the "inputs and outputs" to the pulping and papermaking process so that the mill reuses, recycles, or cleans all waste materials
Kraft pulping was invented in 1884
Soda pulping was invented by Burgess and Watt in England
The link at "Related Link"will take you where papermaking is explained in 100 different ways.
in mechanical pulping we are generating pulp by mechanical based in chemical pulping we are using chemicals to produce pulp chem pulping two types, soda(alkaline) sulphite(acid)
Two ways of getting fibers from wood are mechanical pulping and chemical pulping. Mechanical pulping involves grinding wood logs against a grater to separate fibers, while chemical pulping involves using chemicals to dissolve lignin and separate fibers. The major difference is that mechanical pulping produces higher yield but lower quality fibers, while chemical pulping yields higher quality fibers but with more environmental impact.
