TAILIEUCHUNG - Báo cáo " Methodology for the waste quantity and quality measurement "

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. . | VNU Journal of Science Natural Sciences and Technology 25 2009 145-151 Methodology for the waste quantity and quality measurement. Case study 6 sites in Hanoi Ngo Kim Chi Dang Ngoc Phuong Nguyen Minh Tam Institute of Natural products Chemistry -Vietnamese Academy of Science and Technology 18 Hoang Quoc Viet Hanoi Vietnam Received 17 April 2009 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 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 kg person day in Phan Chu Trinh and Nguyen Du wards and kg person day in Me Tri Kim Giang Dong Anh and Nghia Tan wards where are far from the city center. Keywords solid waste waste quantity and quality measurement. 1. Introduction From March 1st 2008 total area of Hanoi expansion is total population is 6 232 940 people. Hanoi economy has highly developed gross domestic product in 2008 is 1 . Each day Hanoi discharged more than 3 300 tons of waste from households offices restaurants hotels markets food shops 2 .
