- 10. Collection of solid wastes What is Waste Collection? Waste collection is a part of the process of waste management. It is the transfer of solid waste from the point of use and disposal to the point of treatment or landfill. Waste collection also includes the curbside collection of recyclable materials that technically are not waste, as part of a municipal landfill diversion program.
- 11. Classification of collection system Based on the availability of service 1. House-to-House: Waste collectors visit each individual house to collect garbage. The user pays a fee for this service
- 12. 2. Community Bins: Users bring their garbage to community bins that are placed at fixed points in a neighborhood or locality. MSW is picked up by the municipality, or its designate according to a set schedule.
- 13. 3. Curbside Pick-Up: Users leave their garbage directly outside their homes according to a garbage pick-up schedule set with the local authorities (secondary house- to-house collectors not typical)
- 14. 4. Self Delivered: Generators deliver the waste directly to disposal sites or transfer stations, or hire third-party operators (or the municipality).
- 15. Collection Methods Based on mode of operation: 1. Hauled Container System 2. Stationary Container system
- 16. 1. Hauled Container System An empty storage container (Known as a drop- off box) is hauled to the storage site to replace the container that is full of waste , which is then hauled to the processing point , transfer station or disposal site.
- 18. 2. Stationary Container System In this system, containers used for the storage of waste remain at the point of collection. The collection vehicles generally stop alongside the storage containers, and collection crews load the waste from the storage containers into the collection vehicles and then transport the waste to the processing, transfer or disposal site.
