ELECTRONIC WASTE: MANAGEMENT, MATERIAL FLOWS, PRESENT AND FUTURE SCENARIO

Abstract

E-wastesis amongsthe fastestsgrowingssolid waste classes and representssa seriousehazard forsthe environment. Itsconsistssofsmixturesofshazardoussinorganicsandsorganicsmaterials, As, heavy metals, polycyclicSaromatic hydrocarbons, polychlorinatedSbiphenyls, and brominatedS flame retardants, alongswithsvaluablesmetals, such as Au, Ag, and Pd. Directse-waste disposalsto landfills without any prior treatment createssthreatsstosthe environment due to leachingsof metals in water and soil. Improperse-wastesrecycling, such as bysopen burningsandsacid baths, creates hazardoussand toxic compounds, likesdioxins, furans, and acids.

Processing of e-waste in informal way can lead to adverse human health effects and environmental problems. Electronic devices consist of various toxic materials for example lead, cadmium, brominated flame retardant. Recycling of e-waste and disposal of e-waste may lead to various significant health issues to the workers and communities in developed nation and also causes environmental issues. The way to accomplishment as far as e-waste the board, for example, ExtendedeProducereResponsibilitye(EPR)eandeProducereResponsibilityeOrganizatione(PRO) activities have been introduced in a clear way. Electronic waste field can be seen as commercial activity forevitality creation (hydrogeneand power) andeexact recovery of metal for example Au, Ag and Pt trough the process of biotechnology.
