Introduction
Nowadays population are increase .after population are
increasing waste materials are increasing. waste materials are garbage. People
can provide a waste material in new material is known as recycling.
Recycling
Recycling is the process of converting waste
materials into new materials and objects. It is an alternative to
"conventional" waste disposal that can save material and help lower greenhouse
gas emissions. Recycling can prevent the waste of potentially useful materials
and reduce the consumption of fresh raw materials, thereby reducing: energy
usage, air pollution (from incineration), and water pollution (from landfilling).
Recycling is a
key component of modern waste reduction and is the third component of the
"Reduce, Reuse, and Recycle" waste hierarchy Thus, recycling aims at
environmental sustainability by substituting raw material inputs into and
redirecting waste outputs out of the economic system.

Recyclable
materials include many
kinds of glass, paper, cardboard, metal, plastic, tires, textiles, batteries,
and electronics. The composting or other reuse of biodegradable waste—such as food
or garden waste—is also a form of recycling. Materials to be recycled are
either delivered to a household recycling center or picked up from curbside
bins, then sorted, cleaned, and reprocessed into new materials destined for
manufacturing new products.
In the strictest
sense, recycling of a material would produce a fresh supply of the same
material—for example, used office paper would be converted into new office
paper or used polystyrene foam into new polystyrene. This is accomplished when
recycling certain types of materials, such as metal cans, which can become a
can again and again, infinitely, without losing purity in the product. However,
this is often difficult or too expensive (compared with producing the same
product from raw materials or other sources), so "recycling" of many
products or materials involves their reuse in producing different
materials (for example, paperboard) instead. Another form of recycling is the salvage
of certain materials from complex products, either due to their intrinsic value
(such as lead from car batteries, or gold from printed circuit boards), or due
to their hazardous nature (e.g., removal and reuse of mercury from thermometers
and thermostats).
