The document discusses various waste management practices, including waste generation, minimization, recycling, and disposal methods such as landfill and incineration. It highlights the role of the Chennai Solid Waste Management Department, which is responsible for collecting and managing 4,500 metric tons of waste daily. Additionally, it provides a breakdown of waste composition and outlines the procedures for waste collection and transportation.

5. Disposal of waste in a landfill involves burying the
waste and this remains a common practice in most
countries. Landfills were often established in
abandoned or unused quarries, mining voids or borrow
pits. A properly designed and well-managed landfill can
be a hygienic and relatively inexpensive method of
disposing of waste materials

7. Incineration is a disposal method in which solid
organic wastes are subjected to combustion so as
to convert them into residue and gaseous
products. This method is useful for disposal of
residue of both solid waste management and solid
residue from waste water management. This
process reduces the volumes of solid waste to 20 to
30 percent of the original volume.

9. Recycling is a resource recovery practice that refers to the
collection and reuse of waste materials such as empty
beverage containers. The materials from which the items
are made can be reprocessed into new products. Material
for recycling may be collected separately from general
waste using dedicated bins and collection vehicles, a
procedure called kerbside collection

11. Chennai Solid Waste Management
Department:
Headed by a Superintendent Engineer,
the department looks after removal of
solid waste which is a major responsibility
of the Corporation. Every day 4500 MT of
garbage is collected and removed from
the city. Night conservancy is being
carried out in all important roads and
commercial areas of the city. Door to door
collection of garbage is prescribed in all
zones.
