It is the most frequent of all organic compounds. Cellulose is used among other things to produce paper. Long cells, the wood fibres, are vital components of wood. Its walls consist of cellulose, hemicellulose and intercellular cement. The cells are separated chemically or mechanically. Fillers, bonding agents and possibly colourants are added to the fibrous material so that the result is a closed surface. Paper machinery consists of high-tech appliances that use more electronics than an aircraft. All raw materials are mixed in a precise proportion and ground by fibrillation as in a coffee machine, which then make a firm bond in the paper. Sieving, pressing, drying – in a complex process the components are first passed through an all-round continuous sieve, and the paper fibres are deposited on the sieve. Then the paper is pressed together with felt between rollers to further remove water until the paper has a dry content of between 40 and 52 percent. After that, the paper is dried on drying sieves at a temperature as high as 120°. The resulting water vapour is vacuumed off with a huge extractor fan and sometimes even blow-dried with a drying hood. Finally, the residual moisture in the paper is 5-6 percent.
