Converting trees into paper ; recycling paper and cardboard wastes into paper as well. Pulp is a wet slurry " soup " of boiling cellulose, the chemical composition of trees, wood and wood products.

Kraft pulping was invented in 1884
Soda pulping was invented by Burgess and Watt in England
Papermaking starts where the pulping process leaves off
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.

You can make a vegetable coulis out of any vegetable.
Biopulping is a process where fungi are used to degrade lignin in wood fibers, making them easier to separate from cellulose. This method can help reduce the energy and chemical requirements for pulping wood to make paper products.
