“…The wide diversity of informal waste work (buying, selecting, gathering, processing, disassembling e-waste) is thus central to this urban e-waste economy in a process that the authors refer to as "normalisation of informality" (Grant & Oteng-Ababio, 2012, p.18). Similar observations about the close interactions between the putatively separated formal and informal waste management sectors have been made in other contexts, such as China (Chi et al, 2011), Vietnam (Kawai, Osako, Matsui, & Dong, 2012), and Mexico (Frykman, 2006;Hilburn, 2015).…”

In this paper we examine two central concepts of urban metabolism ('system boundaries' and 'flows'), and explore how to approach them as a means to politicise urban metabolism research. We present empirical findings from two case studies of waste management, in Mexico City and Santiago de Chile, looking at: the materiality of waste flows, the actors involved in them, and how waste flows relate to issues of environmental justice. We argue that urban metabolism, as a methodology to understand urban sustainability, has the potential to produce knowledge to trigger urban transformations, and to analyse the social, political and environmental aspects of waste management in urban areas.

“…This stream emerges in isolation from MSW and is mainly driven by economic incentives. This type of recycling is often observed in developing countries [90][91][92], where junk buyers in cities and waste pickers at dumping sites recover recyclables to earn a living [93,94]. The informal sector accordingly contributes to a reduction of MSW generation and drives the recycling process in developing countries [95].…”

Per capita municipal solid waste (MSW) generation, a core indicator of environmental pressure, is a useful measure for evaluating the intensity of waste generation over time and comparing the intensities among cities or countries. We provide an overview of global data on MSW generation per capita at the national and local levels. Although the legal definition of MSW varies from country to country, we conceptualize MSW simply as the waste managed by or for municipalities as a public service. We note the current challenges in estimating MSW generation per capita in developing countries, including a lack of equipment (e.g., weighbridges), lower rates of MSW collection efficiency, and rural-urban migration, all of which may have negative effects on data reliability. Incomplete data compilation systems at the national level also result in lower reliability and reduce the comparability of national data. We suggest technical solutions for estimating MSW generation per capita at the local and national levels to improve reliability and comparability of data.

“…PAYT is a possible future solution to increased generation of MSW from households because it would motivate citizens to recycle and to reduce MSW from households. Implementation of PAYT might encourage citizens to separate and store RW at the source because RW collection at the source by junk buyers is already established in Hanoi city, and junk buyers actively seek out and pay for the RW that they collect (Kawai et al, 2012). Few local governments in Southeast Asia have implemented a PAYT solution for MSW from households, and the feasibility of PAYT for Hanoi city still needs to be verified, taking the local situation into account.…”

Governments of municipalities in Vietnam experiencing dynamic economic growth and dramatic population increases have been struggling to manage increased amounts of municipal solid waste (MSW). This study aimed to clarify the advantages and disadvantages of the current MSW collection service for citizens of the four central districts of Hanoi city, Vietnam, by conducting interviews with 200 households and 200 business entities regarding their satisfaction with the service. The survey results showed that Hanoi city provides an economical collection service with sufficient frequency and at appropriate times for citizens. However, a number of citizens complained about unsanitary conditions in the area surrounding their residence. Business entities had sufficient motivation to sell recyclable waste (RW) to the informal sector, not only to derive revenue from selling RW, but also to reduce the amount of MSW generated, thus reducing the MSW collection fee. Households were not motivated to reduce MSW by selling RW to the informal sector because they paid a fixed collection fee. As a result, an improvement in living standards in the near future is expected to contribute to increasing the amount of MSW generated from households.
