Determination of properties and elemental composition of municipal solid waste in order to proposal of waste-to-energy project in Binh Duong province

Results of elemental composition analysis shown that the contents of C, H, N, Cl, S are ranged from 35,00 to 51,96, from 6,01 to 6,23, from 0,41 to 0,88, from 0,44 to 0,56, from 0,14 to 0,84 %, respectively. On this basis, the author have proposed a waste-toenergy plant with capacity of 250 tons of waste/day to generate the electricity with capacity of 17,0 MW/day. | Journal of Science and Technology 54 (2A) (2016) 56-63 DETERMINATION OF PROPERTIES AND ELEMENTAL COMPOSITION OF MUNICIPAL SOLID WASTE IN ORDER TO PROPOSAL OF WASTE-TO-ENERGY PROJECT IN BINH DUONG PROVINCE Phung Chi Sy1, *, Nguyen Thanh Tuyen2, Nguyen Thi Lien2 1 Environmental Technology Center (ENTEC), 463 Phan Van Tri Street, Go Vap District, Hochiminh city, Vietnam 2 Thu Dau Mot University, No 6 Tran Van On street, Phu Hoa ward, Thu Dau Mot city, Binh Duong province, Vietnam * Email: entecvn@yahoo.com Received: 1 April 2016; Accepted for publication: 15 June 2016 ABSTRACT Domestic solid wastes are classified into 10 samples of 04 groups with different sizes: 2 samples with sizes under and over 120 mm (M1-1, M1-2); 2 samples with sizes under and over 80 mm (M2-1, M2-2); 2 samples with sizes under and over 40 mm (M3-1, M3-2); 4 samples with sizes under 40 mm, 40 to 80 mm, 80 to 120 mm and over 120 mm (M4-1, M4-2, M4-3, M4-4). Results of sorting 10 solid waste samples into food, cloth, wood, plastic, paper, rubber/leather, metal, glass, other organic and inorganic components shown that recycled combustible, non-recycled combustible portions are ranged from 15,46 to 93,90 %, from 5,34 to 80,17 %, respectively. The density of 10 compressed garbage samples is ranged from 525,9 to 2016,7 kg/m3; moisture contents are ranged from 18.03 to 20.92 %. Ash content is ranged from 1.12 to 9.49 % dry weight; Calorific value is ranged from 3164,9 to 5757,0 kcal/kg of garbage. The volume of leached water from 10 kg wet garbage pressed by 250 kg load in 2 days is 300 ml (equivalent to 327,1 g). Results of elemental composition analysis shown that the contents of C, H, N, Cl, S are ranged from 35,00 to 51,96, from 6,01 to 6,23, from 0,41 to 0,88, from 0,44 to 0,56, from 0,14 to 0,84 %, respectively. On this basis, the author have proposed a waste-toenergy plant with capacity of 250 tons of waste/day to generate the electricity with capacity of 17,0 MW/day. Keywords: Solid .
