Recycling is a collection, processing and reuse of materials that would otherwise be thrown away. Materials ranging from precious metals to broken glass, from old newspapers to plastic spoons, can be recycled. The recycling process reclaims the original material and uses it in new products.

    In General, using recycled material to make new products costs less and requires less energy than using new materials. Recycling can also reduce pollution, either by reducing the demand for high-pollution alternatives or the amount of pollution produced during the manufacturing process. Paper products that can be recycled include cardboard containers, wrapping paper, and office paper.

    The most commonly recycled paper products are newsprint. In Newspaper recycling. old newspapers are collected and searched for contaminants such as plastic bags and aluminium foil. The paper goes to a processing plant where it is mixed with hot water and turned into pulp in a machine that works much like a big kitchen blender. The pulp is screened and filtered to remove smaller contaminants. The pulp then goes to a large vat where the ink separates from the fiber and floats to the surface. The ink is skimmed off, dried and reused as ink or bumed as boiler fuel. The cleaned pulp is mixed with new wood fibers to be made into paper again.

    Experts estimate the average office worker generates about 5 kg of waste paper per month. Every ton of paper that is recycled saves about 1.4 cu m (about 50 cu ft) and landfill space. One ton of recycled paper saves 17 pulpwood trees (trees used to produce paper).
