Disposal Operations of Household Waste Generated            Historically, household waste has been disposed of by land filling. As communities became larger and more premises were built, usually at a higher density, particularly in urban areas, the area needed for the disposal of waste increased. Also, as society has developed, there have been significant changes in the composition of wastes collected from households, particularly with a change in the fuel used for heating purposes.
