Management information systems process raw data from office processing systems, such as desktop computers and mobile applications, and transaction processing systems, such as retail point-of-sale systems. The output is sometimes in the form of reports that present aggregated data, which facilitates analysis and decision making.
The cellulose fibers are stuck together with a natural glue called lignin.. When the lignin is removed and the cellulose fibers are separated and reorganized, paper can be made. It's also possible to make paper from a variety of other types of plant fibers, such as cotton, flax, bamboo, and hemp.
Full chemical pulp: produced by chemical methods only; yield about 50%, lignin content 3-5 %. Unbleached pulp: full chemical pulp as it comes from the pulping process, light to dark brown in color. Bleached pulp: white pulp produced by bleaching full chemical pulp. Dissolving pulp: bleached chemical pulp; yield 30-35%, high cellulose content (95% or higher) Kraft process with acid prehydrolysis or acid sulfite process; Improved cellulose purity achieved by a cold alkali extraction. Used for cellulose derivatives production (rayon, Cellulose acetate, cellophane).
