Best Practices

Source Collection

Collection of Municipal Solid Waste at source(Door to door collection) has been implemented in all Zones except Zone VI,VIII & X from May 2003.About 95% of the households were covered under this programme.

This has been achieved only on introduction of Tricycles which stands as a wonder tool for better collection of MSW at door steps. Now about 1459 Tricycles are put in use. The Tricycles were purchased from Councilors fund and some donated by Welfare Associations etc. This has resulted in reduction of dust bins on road side.

Source Segregation

Source separation is promoted to reduce the waste coming to the Landfill, thereby increasing the life time of the Landfills.

  • Source separated bio-degradable waste (Organic Waste) can also be home- composted and used.
  • Source separated recyclables can be sent to recyclable units and only the inserts can be sent to landfills.
