Recycling is the act of processing used materials to make new
products for various reasons. Recycling guards against losing
materials that are potentially useful, and also reduces the need
for using fresh raw materials in manufacturing products. It
reduces air pollution since it prevents incineration and in turn
the harmful gases associated with it. Recycling also prevents
water pollution from making landfills. In the waste hierarchy,
recycling is the third component, preceded by ‘Reduce’ and
‘Reuse’. There are several types of recyclable materials, such
as paper, glass, metal, plastic, textiles and electronics. These
materials are used on a daily basis in households and offices,
and they require responsible management lest they become
problematic to handle. Recycling occurs in two steps, the first
being collecting the waste items, the second being sorting.
Collection of waste items is usually organized in different
systems which are drop off centers, curbside collection and buy
back centers. Drop off centers
