of a municipal landfill diversion
program.

individual house to collect garbage. The user
generally pays a fee for this service.

community bins that are placed at fixed points
in a neighborhood or locality. MSW is picked up

directly outside their homes according to a
garbage pick-up schedule set with the local
authorities (secondary house-to-house
collectors not typical).
4. Self Delivered: Generators deliver the waste
directly to disposal sites or transfer stations, or
hire third-party operators (or the municipality).

6. Collection Method
Based on mode of operation:
1. Hauled Container System

7. Hauled Container System

the container that is full of waste , which is
then hauled to the processing point , transfer
station or disposal site.

Number of Containers = n

9. Stationary Container System
• Stationary Containers : 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.
