Methodology for the waste quantity and quality measurement. Case study: 6 sites in Hanoi

Abstract

To research the volume and components of solid waste, we surveyed household waste with three different incomes (high, middle and low incomes). Then waste is separated into 34 waste components and 9 main waste groups containing organic waste (easily decomposed waste such as vegetable, root, fruit, left food.. to make the compost and difficultly decomposed waste), paper, plastic, metal, glass, rubber and leather, cloth, dangerous substance, and other waste. Besides, definition of all groups of waste is also discussed. The result shows that the ratio of easily decomposed waste is 48.5% and the different sources of waste have the different ratios. The investigative survey chose accidentally 35 households of low, middle and high incomes of each wards, Phan Chu Trinh and Nguyen Du wards. Each survey is implemented continuously during 8 days. Based on the quantity survey, the survey results are 0.572 kg/person/day in Phan Chu Trinh and Nguyen Du wards and 0.545 kg/person/day in Me Tri, Kim Giang, Dong Anh and Nghia Tan wards where are far from the city center.
