Sanitary landfilling is an entirely engineered disposal alternative,
which avoids harmful effects of uncontrolled dumping by
spreading, compacting and covering the wasteland that has been
carefully engineered before use. Through proper site selection,
preparation and management, the operators can lessen the effects
of leachates and gas production both in the present and in the
future. Waste arriving at sanitary landfills site is compacted and
then covered with a layer of soil, usually every day. The compacted
soil layer restricts continued access to the waste by insects,
rodents and other animals. It also isolates the refuse, minimizing
the amount of surface water entering into and gas escaping from
the waste (Turk, 1970). Since all other waste management options
produce some residue that must be disposed off through landfilling,
sanitary landfilling is a necessary component of solid waste
management.
