New characterisation method of electrical and electronic equipment wastes (WEEE).
Innovative separation and beneficiation techniques of various materials encountered in electrical and electronic equipment wastes (WEEE) is a major improvement for its recycling. Mechanical separation-oriented characterisation of WEEE was conducted in an attempt to evaluate the amenability of mechanical separation processes. Properties such as liberation degree of fractions (plastics, metals fe...
متن کاملEnvironmental Information System for Waste Electrical Electronic Equipment (WEEE) Managent: Case Study of Pernambuco (Brazil)
The National Policy on Solid Waste (NPSW) brought a new dimension to waste management in Brazil. According to the requirements of this law, producers, traders, recyclers, importers, distributors, and consumers are each held responsible for waste outcomes. The establishment of reverse logistics systems, also proposed by the law, begins from the management of diffuse interests in support of envir...
متن کاملSimple method for extracting gold from electrical and electronic wastes using hydrometallurgical process
Background: This research studied the feasibility of a simple method for extracting gold from central processing units (CPUs) of computer circuit boards without solvent. Methods: Ceramic and composite CPUs of computer circuit boards were used. Gold was extracted using a hydrometallurgical method in six stages: grinding of CPUs, leaching in nitric acid, leaching in aqua regia, remov...
متن کاملAnalysis of waste electrical and electronic equipment (WEEE) using laser induced breakdown spectroscopy (LIBS) and multivariate analysis.
This study shows the application of laser induced breakdown spectroscopy (LIBS) for waste electrical and electronic equipment (WEEE) investigation. Several emission spectra were obtained for 7 different mobiles from 4 different manufacturers. Using the emission spectra of the black components it was possible to see some differences among the manufacturers and some emission lines from organic el...
متن کاملEvidence of waste electrical and electronic equipment (WEEE) relevant substances in polymeric food-contact articles sold on the European market
In order to confirm the possibility that recycled fractions from the waste electrical and electronic equipment (WEEE) stream were illegally entering the European market in black polymeric food-contact articles (FCAs), bromine quantification, brominated flame retardant (BFR) identification combined with WEEE-relevant elemental analysis and polymer impurity analysis were performed. From the 10 se...
