Paper

Various paper products: a book, toilet paper, ruled paper, carton, and an egg box.

Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibers derived from wood, rags, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fiber evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines

Production

In the industrial process of creating paper, materials containing cellulose such as wood and plants, are stripped of bark, turned into pulp and washed from any contaminants. Then the pulp is "cooked" in a industrial container to liquify any remaining lignin, leaving a almost white cellulose powder, which is further refined to white, rolled into sheets and cut to size

Recycling

The industrial process of recycling paper is done by separating different types of paper, pulping the used paper, washing and rolling into sheets

Historical production

The first production of paper that is most similar to todays process was made in China. A pulp mix of textile and plant material and or bamboo would be made, cleaned and put into a "tub" filled with water, into which two or one wooden frames with a mesh covering one would be sunk into, filled with the pulp and raised above as for the water to fall back into the tub and the pulp would be left on the mesh, then either squeezed from excess water and set to dry, or directly put under the sun
