Title: Plant city recycling

Plant City Recycling

Recycling is a process to change into new
products to prevent waste of potentially useful
material, reduce the consumption of fresh raw
material, reduce energy usage and reduce water,
air pollution by reducing the need for
conventional waste disposal, and the lower
greenhouse gas emissions as compared to plastic
production. Recycling is the key component of
modern waste reduction and is the third component
of the Reduce, Reuse, Re cycle waste. Recyclable
materials include many kinds of glass, paper,
metal, textiles and electronics material.
Although similar in effect the composting or
other reuse of the biodegradable waste such as
food or garden waste- is not typically considered
recycling. Material to be recycled ere either
brought to a collection center or picked up from
the curbside, then sorted, cleaned and
reprocessed it into new materials bound for
manufacturing.

In the strictest sense, recycling of a material
would produce a fresh supply of the same
material, for ex- used office paper would be
converted into the new office paper or used form
polystyrene into new polystyrene. In the another
sense, recycling of a material would produce a
fresh supply of same material- for example used
office paper would be converted into the new
office paper and used foamed polystyrene into new
polystyrene.

However this is often difficult or too expensive
so recycling of many products or materials
involves their reuse in producing different
material instead. Another form of recycling is
the salvage of certain materials from complex
products either their due to their intrinsic
value or due to their hazardous nature. Critics
dispute the net economic and environmental
benefits of recycling over its costs and suggest
that proponents of recycling often make matter
worse and suffer from confirmation bias.

Critics argue that the cost and energy used in
collection and transportation detract from the
costs and energy saved in the production process
also that the job produced by the recycling
industry can be poor trade for the job lost in
logging, mining and other industries associate
with virgin production and that the materials
such as paper pulp can only be recycled a few
times before the material degradation that
prevents further recycling. Proponents of the
recycling dispute each of these claim and the
validity of arguments from both sides has lead to
enduring controversy.
