In many countries today, the local authorities, or the contractors appointed by them, are responsible for collection of garbage from urban neigborhoods. Every urban neighborhood has a large garbage bin allocated to it. Residents or their domestic helps, typically carry their garbage to these collection bins. Alternatively, garbage collection personnel collect garbage door to door and then dump it in these large bins.These large bins are then carried away by personnel travelling alongwith the garbage trucks. The truck will typically have a fixed route everyday. It will lift the large filled garbage bin, empty its contents into the truck and keep the empty bin again at the same place. There will be hundreds of sucjh trucks along different routes everyday.
