The amount of e-waste is growing rapidly in developing countries, and the health and environmental problems resulting from poor management of this waste have become a concern for policy makers. In response to these challenges, a number of Asian developing countries have been inspired by policy developments in OECD countries, and have drafted legislations based on the principle of extended producer responsibility (EPR). However, the experiences from developed countries show that a successful implementation of EPR policies requires adequate institutions and sufficient administrative capacity. Even advanced countries are thus facing difficulties. This paper concludes from existing literature and from the authors’ own observations that there seems to be a mismatch between the typical policy responses to e-waste problems in developing Asia and the capacity for successful implementation of such policies. It also notes that the e-waste situation in developing Asian countries is further complicated by a number of additional factors, such as difficulties in identifying producers, import of used electronic products and e-waste (sometimes illegal), and the existence of a strong informal waste sector. Given these challenges, the authors conclude that comprehensive EPR policy schemes of the kind that have been implemented in some advanced countries are not likely to be effective. The paper therefore proposes an alternative phase-in approach whereby developing Asian countries are able to move gradually towards EPR systems. It argues that this approach would be more feasible, and discusses what could be the key building blocks of each implementation stage.

Waste reduction and recycling at the city level will acquire greater significance in the near future due to rising global volumes of waste. This paper seeks to identify policy-relevant drivers for successful promotion of waste reduction and recycling. Factors influencing the success of waste reduction and recycling campaigns are identified. Two case study cities in Japan which depict the successful use of the 3Rs (reduce, reuse and recycle) at the municipal level are presented. In these cases, the existence of incinerators, which are generally considered as disincentives for recycling, was not functioning as a disincentive but rather as an incentive for waste reduction. Owing to the high cost of incineration facilities, the movement to close incinerators has become a strong incentive for waste reduction and recycling in these two cities. The study suggests that careful consideration is necessary when making decisions concerning high-cost waste treatment facilities with high installation, maintenance and renewal outlays. In addition, intensive source separation and other municipal recycling initiatives have a high potential for producing positive results.

The global consumption of natural resources is soaring, especially in rapidly industrializing economies. This increasing demand is depleting resource stocks and is a major driver of other environmental problems, including climate change and waste. With rising prices and growing concerns about resource access, these trends are increasingly attracting policy makers’ attention. Some developed countries have devised indicator systems, based on economy‐wide material flow analysis/accounting (EW‐MFA), to monitor resource consumption. This article consists of two separate but related parts: (1) a study of how EW‐MFA indicators are used in a number of developed countries, including analysis of the commonalities between countries that are actively using these indicators in policy, and (2) a survey of the current capacity for EW‐MFA in developing countries, including data availability and policy uptake. This study found that countries in which policy makers show a great interest in EW‐MFA indicators are characterized by large resource imports and large net export of manufactured goods. Many rapidly industrializing countries demonstrate similar characteristics. The study of developing countries found that many of the data for EW‐MFA exist, but collection is fragmented and access is limited. This article recommends that capacity development of EW‐MFA in rapidly industrializing economies should first coordinate a national focal point and then raise awareness among government officials, strengthen institutions collecting EW‐MFA data, and train researchers and experts in EW‐MFA techniques and effective policy interaction.

The trade in secondhand electrical and electronic equipment (EEE) is increasing in Asia, and growing environmental problems caused by improper recycling in developing countries have been reported. However, the current policy frameworks are not sufficient to assure safe and beneficial international reuse. In order to support the development of an appropriate policy response to assure reasonable reuse, this paper first tries to identify the major issues associated with international trade of secondhand EEE; then, it argues that, for further policy development, it is important to identify key actors in the international trade network for secondhand goods and to analyze their incentives.
