Abstract

One method of time and motion study on solid waste collection and transportation was used in 6 investigated sites in Hanoi. Survey sheets have been designed and trained to carrying out study waste collection by hand push cart/waste binsalong assigned routes and the load by trucks at the loading point in the streets, volume of collected waste, time of loading and transportation, time of each activity of waste  collection. The results showed  that;  sweeping  and picking up waste discharged in to the pavements was the most time consuming accounting for 60% of the total  time.  One  waste collector collected  an  average  of  about  824kg/person/day, an  average volume of 14.8tons/day colleted in Nguyen Du ward; average of  616kg/person/day  and  the amount of 11 tons/day collected in Phan Chu Trinh ward. The organic waste with about 20-25% of the total generated waste was separated from thenormal - landfilled waste going to the Cau Dien composting plant by waste separation at source(WSS) in Phan Chu Trinh and Nguyen Du wards. In other sites without WSS such as Kim Giang, Me Tri, Nghi Tan, Dong Anh town, the volume of waste is 6,3 tons/day, 25,6 tons/day, 53,4 tons/day, 16,1 tons/day respectfully. One waste collector collected an average of 782, 640, 847, 503kg/person/day in Kim Giang, Me Tri, Nghia Tan, Đong Anh town.
