Countries with emerging legislation on the waste electrical and electric equipment (WEEE), but limited infrastructure, may find in other, more robust, systems tools to develop adaptable socioeconomically viable management schemes. Additives found plastics electronic goods, such as brominated flame retardants (BFRs), are components of a safety system, introduce characteristics that result their ...
The process of recovering metals from electronic waste has become an important topic in recent years. In this work, the recovery electrolytic copper ashes produced during pyrolysis electrical and equipment (WEEE) was sought. Three gravimetric separation were used: Wilfley table, JIG screen, mechanical screen. This last method used with without previous grinding processes. initially characterize...
The increase in the use of electrical and electronic devices worldwide has created a rapid growth waste equipment (WEEE). current paper presents an optimization-based simulation (OBS) approach that allows design sustainable WEEE management system policies. proposed OBS integrates dynamics (SD) model mixed-integer nonlinear programming (MINLP) to improve representation performance processes cons...
The European perspective on waste management and recycling as described in the European Union’s Waste of Electrical and Electronic Equipment (WEEE) and Restriction of Hazardous Substances (ROS) strongly suggests that lead-free electronic assemblies will be mandatory in Europe by 2008. Japan is moving toward voluntary compliance by 2003 with a lead-free initiative that focuses on environmental m...
The increasing adoption rate of photovoltaic power generation shows that renewable energies have a bright future. Yet, this could be overshadowed by the unintended consequence increased Waste Electric and Electronic Equipment (WEEE) at installations’ End-of-Life (EoL) stage. As countries find themselves dealing with WEEE issue, they may adopt different practices which, if wrongly implemented, p...
Salinity influences on the response of Mytilus galloprovincialis to the rare-earth element lanthanum
The multiplicity and wide variety of applications electrical electronic equipment has largely increased with the technological economic progress and, in consequence, amount generated waste (WEEE). Due to inappropriate processing disposal WEEE, different chemical elements compounds, including rare-earth such as Lanthanum (La) have been released environment. Nevertheless, environmental risks resu...
The recovery of metals from the waste electrical and electronic equipment (WEEE) is a major challenge to preserve natural resources. Hydrometallurgy, where are leached, promising method but generates large amounts polluting effluents. In this study we design aqueous leaching foams, composed 90% v/v gas 10% HCl solution oxidize dissolve copper. We take advantage oxidizing power dioxygen (O2) pre...
Introduction Acrylonitrile-butadiene-styrene copolymer (ABS) and high impact polystyrene (HIPS) are plastics typically found in waste electrical electronic equipment (WEEE or e-waste). As such, recycling is a beneficial method for reintroducing polymeric materials from to the same production cycle. This study aimed investigate mechanical of ABS HIPS WEEE reprocessed six times, totaling 24 cycle...
