Recycling paper consists of the process of transforming the type used into new units for use. Industrial process of removal of printing ink, invention of the German jurist Justus Claproth.
Governments directly support companies that do the work of recycling paper and other types of waste. There are three categories that can be used as raw material: Sawmill industry, pre-consumer waste and post-consumer waste.

How Does Recycling Industry Paper? |
Pre-consumption wastes: Material that left the paper mill, but was discarded before it was ready for consumer use;
Post-consumer waste: Discarded after-consumer material, such as old corrugated containers, old magazines, old newspapers, office paper, and old telephone directories.
Paper Recycling Processes
01-The process of recycling paper involves mixing used with water and chemicals.
02-Then the paper should be chopped, heated and divided into cellulose chains, a type of organic plant material. The resulting blend is called pulp, or pulp.
03-The screens provoke tension that remove any glue or plastic that may still be in the mix
04-Following the same screens are cleaned, bleached, mixed with water, removed to dry and ready!
05- The same fibers can be recycled around seven times!
Why Recycle Paper?
Manufactured paper has an effect on the environment, both upstream (where raw materials are procured and processed) and downstream (waste disposal impacts).
Nowadays, ninety percent of paper pulp is created from wood. Production is equivalent to about forty percent of the trees felled every year on a global scale to represent 1.2 percent of the world's total economic output.
Recycling one ton of newsprint saves about a ton of wood, while recycling a ton of print or
waste paper can save two tons of wood.
The US Environmental Protection Agency (EPA) concluded that recycling made it happen 35% less water pollution and 74% less air pollution responsible for making the paper virgin.
Pulp mills can be sources of air and water pollution, especially if they are producing the bleached type. Modern industries produce far less pollution than a few decades ago.
Recycling paper decreases the demand for virgin cellulose and therefore reduces the overall amount of air pollution and water associated with manufacturing. Recycled pulp can be bleached with the same chemicals used in pulp.
Sodium hydrogen peroxides are the most common bleaching agents. Recycled pulp, or paper made from it, is known as PCF (chlorine-free process) if there are no chlorine-containing compounds used in the recycling process. However, recycling plants may have polluting by-products, such as sludge, for example.
Books and Recycling
In the mid-nineteenth century there was an increased demand for books and writing material. Until that time, the papermakers used linen rags discarded for the paper, but the supply did not keep up with the increase in demand.
Internationally, about half of all recycled paper comes from conversion losses (pre-consumer recycling), such as scraps and unsold newspapers.
Get some statistics on paper consumption:
The average use of paper per capita around the world was 110 pounds (50 kg). Estimated that 95% of business information stores paper.
Recycling a short ton (0.91 t) of paper saves seventeen mature trees, seven thousand gallons of water, three cubic meters (2.3 m3) of landfill space, two barrels of oil and 4,100 kilowatt hours of electricity - enough to supply the average American home for six months.
There are 115 billion sheets of paper used annually for personal computers. Average web user prints 28 pages per day. Corrugated boxes have more than 25% recycled fiber around the world. Some spend 100% on the recycling process!
Recycling Paper in Europe
Paper recovery in Europe has a long history and gradually has become mature and respectable organization by large parts of the main countries of the continent. European manufacturers and converters work together to meet the demands of the European Commission and national governments.
In 2004 the paper recycling rate in Europe was 54.6% or 45.5 million short tons. The index reached 64.5% in 2007. It met the voluntary goal of 66% in 2010 according to official data, although some critics do not really believe.
Recycling in the United States
In 1690, the first paper factory to use recycled clothing was established, established by the Ritten house family;
1896: The first recycling center was started by the Benedetto family in New York, where they collected rags, newspapers and trash with a wheelbarrow;
1993: First year with more recycled paper than buried in landfills;
More than half of the paper used in the United States collected is recycled. The products are still major component of urban solid waste, accounting for 40% of landfill composition.
In 2006, a record 53.4% of paper used in the US (or 53.5 million tonnes) was recovered for recycling. The paper industry has set a goal to recover 55 percent of all type used in the United States in the year 2012.
Recovery of paper-specific packaging for paper products used by the packaging industry accounted for about eighty percent of recycled packaging materials. Values in excess of £ 24,000,000 recovered in 2005 were recovered.
In 1998, about 9,000 sidewalk programs and 12,000 recyclable points appeared in the USA. As of 1999, 480 materials recovery facilities had been established to process the materials collected.
In 2008 the global financial crisis caused the price of old newspapers to fall in the US from $ 130 to $ 40 per short ton.
