Did you know that to produce the Sunday's newspaper 500,000 tree's must be cut down?(1) How about the first piece of paper as we know was produced in AD 105 by Ts'ai Luin? Americans recycled more than 50% of the paper that we used in 2008, but that isn't enough.(2) Recycling paper is very important to preserve our society, culture, and the world we live in. toc

There are a lot of benefits in recycling white paper.
 * For every ton of paper recycled the savings are at least 30,000 liters of water and 3000-4000 kilo-watts electricity (which is enough for an average 3 bedroom house for one year) compared to making new paper. (3)
 * Recycled paper produces fewer polluting emissions than harvesting new paper. (3)
 * Recycling saves money, landfill space,conserves our valuable natural resources, creates jobs and also saves energy. Did you know if we have recycled a ton of white paper we would saves as much as 7000 gallons of water. (3)

What is it Recycled into?
White paper is recycled into many products we use today. It's recycled into tissues, toilet paper, napkins, folders, cardboard, baskets, post it notes, candy wrappers, notebooks and even calendars! (4)

 * 1) After paper is used it is transferred to a local recycling center where it is sorted into different grades (cardboard, computer paper, construction, etc.)[[image:Beater02.jpg width="262" height="172" align="right" caption="A paper beater at an old-style paper mill. (7)"]]
 * 2) After it is separated it is then compacted into large bales and shipped to a nearby paper mill.
 * 3) To begin the recycling process the paper is shredded and mixed with hot water into a pulp.
 * 4) The pulp is cleaned of any contaminants (well explained in video below).
 * 5) The refined pulp is turned to slush in a beater and the slush is mixed with virgin-paper slush.
 * 6) The paper making process begins and the recycling process ends. (5)

History of Paper Recycling
Paper was invented in 105 A.D. by Chinese scholar Ts'ai Lun (although newer research shows it was invented up to 200 years earlier it was most likely primitive and rough). Ts'ai Lun first made paper out of bamboo, mulberry bark, linen, and china grass but it was soon made out of other materials also. In Egypt papyrus plant was long used for the same purpose. Modern paper was named after papyrus. In 1456 sheep skin was used to write many manuscripts on including [|Gutenberg's Bible]. In 1719 a French scientist named Rene de Reaumur found wasps making nests out of chewed slivers of wood. He theorized that paper could be made from wood also. In the 19th century his theory was proven correct and white paper was born.
