摘要：Despite being generally poorly recognized by public authorities, informal recycling remains nevertheless a major component in the waste sector, which questions the legitimacy of the official waste arrangements. A look at the current transformation in Hanoi (Vietnam), Delhi (India) and Surabaya (Indonesia) allows us to understand the socio-technical aspects of infrastructural choices in the management of waste generated in fast-growing Asian cities. The three cases present similar traditional recycling practices yet contrasted (non-) regulation within their waste policies. From the co-existence of a municipal waste management service with a traditional informal recycling sector, to an opposition between both, there is also a possibility of making use of the existing local practices to achieve a more sustainable system.
