Solid waste generation is a natural phenomenon and amount of
waste produced is directly proportional to the population growth.
Less population means less demand for food and shelter, as well as
lesser pressure on other natural resources for their various needs.
The last five decades have resulted in an uncontrolled exploitation
of different kinds of natural resources due to rapid urbanization,
industrialization and changes in the way of life. The uncontrolled
misuse of the abundant resources has finally resulted in genera-
tion of a huge quantity of complex solid waste. The sustainable
waste management practices are necessary to keep the environ-
ment clean and green. In present circumstances it is advisable that
waste products of one industry should be investigated be with an
intention to use it as raw material for other industry to get the
desired product.
