Why is solid waste disposal a major problem for towns and
cities?• It is an expensive undertaking, the
second largest expenditure after education
• It takes up valuable and expensive land close to towns and cities
• It devalues nearby land properties • Pollutes groundwater, air and produces
pungent odor• The garbage disposal process represent
a waste of natural resources.
