Recycling involves the collection, processing, and reuse of materials that would otherwise be discarded, significantly reducing costs and energy usage compared to new materials. Paper products, especially newsprint, are commonly recycled through a process that removes contaminants and reclaims fibers for new paper production. Recycling one ton of paper saves landfill space and preserves trees, highlighting its environmental benefits.

EXPKANATION TEXT

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 materials 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 by minimizing 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 product is newsprint. In newspaper recycling, old
newspapers are collected and searched for contaminants such as plastic bags and aluminum
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 paper fibers and fl oats to the surface. The ink is skimmed off, dried and reused as ink or
burned 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 wastepaper per month.
Every ton of paper that is recycled saves about 1.4 cu m (about 50 cu ft) of landfill space. One
ton of recycled paper saves 17 pulpwood trees (trees used to produce paper).
