| Abstract: |
| Pollution of domestic solid wastes in the rural areas of China has drawn increasing attention. In the rural areas of the Yunnan-Guizhou Plateau, Southwest China, nine villages were randomly selected to investigate the characteristics of domestic solid wastes, people’s knowledge of domestic wastes and willingness to participate in domestic waste management using questionnaires, field sampling and laboratory tests. The domestic solid wastes were generated at averagely 160 g·d-1 per capita and mainly consisted of kitchen waste, dust, plastics, paper and wood. The bulk density, moisture content, ash, combustible materials and calorific value of these wastes were 106 kg·m-3, 39.16%, 19.48%, 41.37% and 7615 kJ·kg-1, respectively. In this area, the public′s perceptions of pollution caused by the domestic solid wastes came primarily from their direct senses; the public′s knowledge of wastes recycling was influenced greatly by the local recyclers’ conducts; the people′s awareness of the hazardous wastes was limited. However, the public showed strong willingness to pay for the wastes disposal and participate in the waste management. Our investigation shows the possibility to develop management and treatment systems of domestic solid wastes in the rural area of the Yunnan-Guizhou Plateau. |
