The process of waste paper recycling most often involves mixing used/old paper with water and chemicals to break it down.
It is then chopped up and heated, which breaks it down further into strands of cellulose, a type of organic plant material; this resulting mixture is called pulp, or slurry.
although there is debate concerning the actual energy savings realized.
The Energy Information Administration claims a 40% reduction in energy when paper is recycled versus paper made with unrecycled pulp, Some calculations show that recycling one ton of newspaper saves about 4,000 k Wh (14 GJ) of electricity, although this may be too high (see comments below on unrecycled pulp).
Relating tons of paper recycled to the number of trees not cut is meaningless, since tree size varies tremendously and is the major factor in how much paper can be made from how many trees.
The Programme for the Endorsement of Forest Certification (PEFC) and the Forest Stewardship Council (FSC) certify paper made from trees harvested according to guidelines meant to ensure good forestry practices.Pulp mills can be sources of both air and water pollution, especially if they are producing bleached pulp.Modern mills produce considerably less pollution than those of a few decades ago.It is strained through screens, which remove any glue or plastic (especially from plastic-coated paper) that may still be in the mixture then cleaned, de-inked, bleached, and mixed with water. Today, 40% of paper pulp is created from wood (in most modern mills only 9-16% of pulp is made from pulp logs; the rest comes from waste wood that was traditionally burnt).Paper production accounts for about 35% of felled trees, This is because kraft pulping requires twice as much wood since it removes lignin to produce higher quality fibres than mechanical pulping processes.The recycling of paper is the process by which waste paper is turned into new paper products.It has a number of important benefits besides saving trees from being cut down.Up to that time, paper manufacturers had used discarded linen rags for paper, but supply could not keep up with the increased demand.Books were bought at auctions for the purpose of recycling fiber content into new paper, at least in the United Kingdom, by the beginning of the 19th century.S., down from more than 87 million tons in 2000, according to the U. Paper products used by the packaging industry were responsible for about 77% of packaging materials recycled, with more than 24 million pounds recovered in 2005.By 1998, some 9,000 curbside recycling programs and 12,000 recyclable drop-off centers existed nationwide.
