The main objective of this paper is to characterise, both physically and chemically, waste electric and electronic toys, belonging to the category 7 of the Directive, 2012/19/UE, in order to obtain information about the generation and composition of this waste which is not widely found in the literature. For this, a campaign was designed with the aim of collecting a representative sample of waste toys in different schools in a Spanish town. Altogether 1014.25 kg of waste toys were collected, of which 31.83% corresponded to the electric and electronic fraction, which is the object of study. The collected wastes were divided into subcategories and a representative sample of each was one used to characterise them physically and chemically. Physical characterisation provided information about the materials they were made of, the electrical and electronic parts, fixing and assembly systems, and so forth. The results showed that the weight of a toy is comprised of 72.30% of plastics, 12.07% of electrical and electronic components, 4.47% of metals, and 11.15% other materials. In general, the most common types of polymers were PS, PP and ABS. Chemical characterisation made it possible to analyse the composition of the plastic components, which is information that is essential to be able to determine the feasibility of recovering the resulting fractions. The results showed that the content of hazardous substances in these plastics is far below the limits stipulated in Directive 2002/95/EC (RoSH Directive). The findings of this study show a need for a specific management system for this fraction of domestic wastes and a wide range of potential reusability of the discarded toys since 65% of the toys from the collected sample worked in perfect condition. We also found that the end-of-life is one of the aspects that have not been considered during their design as both materials and disassembly sequence do not facilitate the end-of-life of this type of wastes. This information could be used to improve the ecodesign of electrical and electronic equipment toys regarding their end-of-life. 相似文献

This paper takes a first step in comparing and synthesising the emerging concept of energy justice with extant ethical consumption literatures as two complementary theoretical approaches to ethics and consumption. To date, theories of ethical consumption and energy justice remain somewhat disconnected, so while they have some areas of potential comparability, these have not yet been fleshed out or developed. To address this lacuna, this paper explores areas where research into ethical consumption might be useful for furthering concepts of energy justice. More specifically the discussion draws on the philosophical foundations, the relationship between consumption and development, and the role of transparency and visibility in reconnecting consumption and production practices as the main areas of overlap in these literatures. The conclusion points to some lessons for emerging energy justice literatures that can be drawn from this task of comparison and synthesis. 相似文献

A common assumption in the economic valuation of the environment is that environmental resources can essentially be treated identically to produced goods and services in estimating welfare measures. The most critical aspect of this assumption in this regard is that individuals are willing to trade-off environmental quality changes in exchange for changes in their income. In this paper, we briefly review some of the conceptual arguments over this issue, and existing empirical evidence, before presenting the results of a new pilot study which addresses some of the possible problems in viewing the environment in this fashion. 相似文献

全氟化合物的分布、累积及生态毒理学效应 总被引:1,自引:0,他引:1
全氟化合物(Perfluorinated compounds,PFCs)污染在全球范围内已普遍存在,其在环境中的浓度增长迅速,受到人们越来越多的关注。环境中PFCs的迁移转化规律决定其环境效应,是进行环境和健康风险评价的基础。目前关于PFCs的研究主要集中于水体及生物体内PFCs的分析检测,对其生态毒理效应的研究尚处于初步阶段。本文介绍了PFCs研究现状,综述了PFCs在环境中的分布模式、生物体内的蓄积规律以及环境中PFCs的生态毒理效应等方面的最新研究进展,同时也阐述了PFCs污染对人体健康的影响,并提出了未来PFCs研究亟待解决的问题。 相似文献
