title: [Analysis of composition characteristics of municipal solid waste in south China].
abstract: Using the MSW (municipal solid waste) sampling and analysis methods, the composition characteristics of MSW in south China were investigated. The results showed that: the average MSW bulk density was 0.22 x 10(3) kg x m(-3), the percentages of water, ash and combustible were 55.0%-66.9%, 18.6%-30.3% and 69.7%-81.4%, respectively. The organic contents were 50.1%-58.0%. The waste low caloric value (wet base) ranged 6570-9652 kJ x kg(-1), and the average of waste low caloric value(wet base) was 8272 kJ x kg(-1), which was higher than the recommended value of World Bank(7000 kJ x kg(-1)). The percentage composition of MSW was: 39.8%-53.3% kitchen waste garbage, 16.5%-33.4% rubber and plastics, 5.61%-7.95% paper, 1.14%-5.16% textile products, 2.49%-5.12% bamboo products, 1.10%-1.47% glass, 5.86%-7.57% mixed materials, 2.46%-6.73% dust, 0.1%-0.32% metal, and 0.4%-0.69% ceramic. The correlation analysis and factor analysis showed that: the high proportions of textile, rubber and plastics, paper, and combustible materials had a positive effect on the MSW incineration, while the high proportions of kitchen waste garbage, glass, MSW bulk density, ash, water content and dust had a negative effect on the MSW incineration.
