The waste
hierarchy refers to the "3 Rs" reduce, reuse and recycle, which
classifies waste management strategies according to their desirability in terms
of waste minimization. The waste hierarchy is the cornerstone of most waste
minimization strategies. The aim of the waste hierarchy is to extract the
maximum practical benefits from products and to generate the minimum amount of
end waste.
Life-cycle of a product
The
life-cycle begins with design, then proceeds through manufacture, distribution,
and primary use and then follows through the waste hierarchy's stages of
reduce, reuse and recycle. Each stage in the life-cycle offers opportunities
for policy intervention, to rethink the need for the product, to redesign to
minimize waste potential, to extend its use. Product life-cycle analysis is a
way to optimize the use of the world's limited resources by avoiding the
unnecessary generation of waste.
