The main purpose of this paper is to review and compare E-waste management systems operating in East Asian countries in efforts to identify future challenges facing the circulative economies in the region. The first topic of this paper is cost sharing (physical and financial) as applied to the various stakeholders, including producers, consumers, local governments and recyclers, in the E-waste ...

this study was conducted to identify emission characteristics of certain hazardous substancescontained in the plastic of used home electrical and electronic appliances keeping in view compliance with therestriction of hazardous substances (rohs) directive and to estimate the possibility of safe recyclingpractices. according to the results, the concentration of cadmium, lead, mercury and chromiu...

Rapid economic growth in Asia and the increasing transboundary movement of secondary resources will increasingly require both 3R endeavors (reduce, reuse, recycle) in each country and appropriate control of international material cycles. Recently, managing electrical and electronic waste (E-waste) has become an important target for domestic and international material cycles from the viewpoints ...

As the need for a more circular model is being increasingly pronounced, a fundamental change in the end-of-life (EoL) management of electrical and electronic products (e-products) is required in order to prevent the resource losses and to promote the reuse of products and components with remaining functionality. However, the diversity of product types, design features, and material compositions...

In reverse supply chain of e-waste, collectors (collecting e-waste from all kinds of resources) and processors (disassembling and disposing e-waste) play key roles and have connections based on interests. We present a Stackelberg leader(collector)follower(processor) dynamic game model with profit maximization purpose. When the supply and demand are relatively clear, major risk for the processor...

Electrostatic and/or high tension separation has been used for the separation of rare metal bearing minerals, foods, industrial wastes, and so on. Since the separation is achieved by the difference mainly in surface conductivity of materials, the efficiency in humid circumstances is very low and the applicability is considerably limited. We applied the following two-stages pretreatment techniqu...

This paper develops a new performance evaluation approach for evaluating the relative recycling sustainability performance of e-waste products in terms of their contribution to the corporate sustainability of an e-recycling company. A fuzzy pairwise comparison process is used to help make comparative assessments. A fuzzy technique for order preference by similarity to ideal solution (TOPSIS) is...

Medical centers including hospitals, clinics and places where diagnosis and treatment are conducted generate wastes that are highly hazardous and put people under risk of fatal diseases. Although the understanding of medical waste management and control techniques is important, technical elective courses that are offered in undergraduate chemical, civil or environmental engineering place less e...

BACKGROUND The population exposed to potentially hazardous substances through inappropriate and unsafe management practices related to disposal and recycling of end-of-life electrical and electronic equipment, collectively known as e-waste, is increasing. We aimed to summarise the evidence for the association between such exposures and adverse health outcomes. METHODS We systematically search...
