Critical materials share the same insufficiencies in their life cycles; low recycling rates and a high degree of dissipative losses. The limitations for the secondary use of critical materials are their minor concentrations in final products, their dissipative applications, and the fact that they are irreversibly mixed with other material flows in current recycling practices. This is exacerbate...

Safe management of electronic and electrical waste (e-waste/ WEEE) is becoming a major problem in many countries around the world. In particular, developing countries face number of issues with the generation, transboundary movement and management of e-waste. It is estimated that the world generates around 20-50 million tonnes of e-waste annually, most of it from Asian countries. Improper handl...

The treatment of cooling appliances in Austria is mainly influenced by two factors. On the one hand is the changing composition of cooling appliances because of the CFC phase out, on the other hand are the minimum recycling rates stipulated by the ordinance on Waste Electrical and Electronic Equipment (WEEE ordinance). Two basic treatment practices can be identified in Austria: One type aiming ...

Technologies to collect and reuse sulfuric acid waste is attracting attention to reduce industrial waste in semiconductor manufacturing plants. Reusing sulfuric acid has a high economic value. By using sulfuric acid recycling equipment based on an atmospheric distillation method, we evaluated the recovery percentage of sulfuric acid, the concentration and quality of recycled sulfuric acid, and ...

E-waste, a relatively recent addition to the waste stream in the form of discarded electronic and electric equipment, is getting increasing attention from policy makers as the quantity being generated is rising rapidly. One of the most promising policy options to address this issue is to extend the producers responsibility for their products beyond the point of sale, until end-of-product-life. ...

BACKGROUND Electronic waste workers are prone to various illnesses and injuries from numerous hazards thus the need for them to seek health care. The aim of this study was to describe health-seeking behavior, and social and other factors affecting this behavior, among electronic waste workers at Agbogbloshie, Accra, Ghana. METHODS In-depth interviews were conducted and analyzed qualitatively ...

large volumes of mostly irreparable electronic waste (e-waste) are shipped to africa on a monthly basis, of which nigeria receives the largest share. e-waste management practices in nigeria have remained completely primitive until date; and e-waste workers have little or no occupational safety knowledge and devices. the thousands of chemicals in e-waste have been reported to be toxic to human h...

BACKGROUND AND OBJECTIVES: The sheer volume of electrical and electronic waste (e-waste) has presently been generated in Vietnam, posing a growing concern regarding its impact can have on the environment and human health. Therefore, the need for developing policies and regulations towards the environmentally sound management of e-waste is becoming crucial. Although the municipa...

The fate of used electronic products (e-waste) is of increasing concern because of their toxicity and the growing volume of e-waste. Addressing these concerns requires developing the recycling infrastructure, but good estimates of the volume of e-waste stored by US households are still unavailable. In this context, we make two contributions based on a national random survey of 2136 US household...
