| Abstract: |
| To explore appropriate methods for the classification, collection, and transportation of rural domestic wastes (RDWs), a field investigation concerning the potential impact factors on waste classification was carried out at 10 villages in Hangzhou, Zhejiang Province. A physical composition analysis of RDWs showed that kitchen wastes, paper, rubber and plastics, textiles, dust, and glass were the main components, accounting for 55.9%, 9.0%, 10.8%, 5.7%, 4.0%, and 7.2% of the total weight, respectively. The proportions of putrescible wastes, which were suitable for disposal by composting, recyclables, and hazardous wastes in RDWs were 55%, 20%, and 1%, respectively, in Hangzhou. Accordingly, dichotomy (dividing domestic wastes into putrescible wastes and other wastes) was a comparatively feasible source classification method during the promotion stage of RDW classification. With the implementation of this source classification method, RDWs were generally collected and transported through three patterns in rural Hangzhou. An economic evaluation indicated that the adoption of different collection and transportation patterns resulted in a discrepancy in the cost of RDW classification. An operational status evaluation revealed that adopting different patterns had an evident impact on the effective collection ratio of putrescible wastes, and a significant effect on the source classification accuracy of RDWs. In addition, management and social evaluations illustrated that the pattern choice had significant effects on the management efficacy of grassroots management executives, and public acceptance toward waste classification. This study indicated that door-to-door collection and transportation of both putrescible wastes and other wastes was relatively suitable during the early stage of RDW classification. |
