In other areas, an improvised form of house-to-house collection involves a worker with a handcart who traverses each street. He rings a bell so that local residents can hear him coming, whereupon they leave their residences and deposit the waste in his cart. Once the handcart is full, the worker either unload it in a community bin or deposits it in a transport vehicle. More often than not, public participation is limited. Consequently, it is not uncommon to see waste is littered around the community bins.
