Evaluating municipal solid waste system and plastic waste leakage in Dong Ha City, Vietnam

Tóm tắt

This study applied a waste flow diagram to clarify the status of municipal solid waste generation and waste flows, as well as model plastic waste leakage into the environment of Dong Ha City, Vietnam. Results denoted that the amount of municipal solid waste generation was about 0.66 kg/capita/day, being lower than estimated results of other Vietnamese cities. The majority of municipal solid waste generation was collected by formal collection service, at around 23,291 tonne/year, accounting for about 90% of total municipal solid waste generation. Around 5% of municipal solid waste (about 1,360 tonnes/year) was separated and recovered for recycling through the informal sector. Uncollected plastic waste (71%) and plastic waste leakage during collection and transportation (28%) were the two main sources contributing to plastic leakage. Thus, enhancement of the collection system plays the most important role in controlling plastic waste leakage.
