Best Practices |
Source Collection
Collection of Municipal Solid Waste at source(Door to door collection) has been implemented in all Zones. 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 2800 Tricycles are put in use. 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.
