Best Practices

Collection of Solid Waste at Source
           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 5400 Tricycles are in use for reduction of dust bins on road side.

Source Collection

           Source separation is promoted to reduce the waste coming to the Landfill, thereby increasing the life time of the Landfills.
           The bio-degradable waste (Organic Waste) is being composted in a decentralized manner at ward level by Ordinary and Vermi compost plants and Bio methanation plants and manure used for GCC parks and greeneries besides open sale to public also.
           Source separated thin plastics are subjected to shredding in all units / zones and it has been used for laying Bituminous road laying. The source Separated non biodegradable (Dry Waste) collected on every Wednesdays for recycling.
