  • Paper recycling Wikipedia

    The recycling of paper is the process by which waste paper is turned into new paper products It has a number of important benefits: It saves waste paper from occupying homes of people and producing methane as it breaks down Because paper fibre contains carbon (originally absorbed by the tree from which it was produced), recycling keeps the carbon locked up for longer and out of the atmospherePaper, whether produced in the modern factory or by the most careful, delicate hand methods, is made up of connected fibers The fibers can come from a number of sources including cloth rags, cellulose fibers from plants, and, most notably, trees The use of cloth in the process has always produced highquality paperHow paper is made material, manufacture, making, how to· The history of the kraft pulping process is obscure, and few patents and stories try to explain the origin of this chemical pulping process The story that most likely explain its origin goes back to the 1870s in a soda mill, where a chemical recovery plant operator made a mistake in the process of adding sodium carbonate (Na 2 CO 3) for chemical losses, he added instead sodium sulfate (Na 2The role of sulfidity during kraft pulping Pulp and
