Recycling-oriented characterization of small waste electrical and electronic equipment

As a result of the continuous change in the design and function of consumer electrical and electronic products, the mechanical and material properties of the obsolete products, called waste electric and electronic equipment (WEEE), are highly variable. The variability within WEEE is explained by the number of different appliances, and the heterogeneity in composition of any given appliance.This paper reports on an extended investigation of the properties of WEEE, in particular small appliances. The investigation focuses on the analysis of the composition of about 700 single appliances. Firstly, analytical methods to characterize the waste equipment are described. The results of the experimental analyses show that the mechanical properties, the material composition, the polymer composition and the chemical composition of WEEE vary not only between equipment types with different functions, but also between single appliances within one equipment type. Data on hazardous and valuable substances in selected equipment types are presented.Using detailed data on the composition of individual appliances to calculate rates of recovery for assumed recycling processes demonstrates that the performance of recycling processes depends strongly on the composition of WEEE. Recycling-oriented characterization is, therefore, a systematic approach to support the design and the operation of recycling processes.     

Facile characterization of polymer fractions from waste electrical and electronic equipment (WEEE) for mechanical recycling

In view of the environmental problem involved in the management of WEEE, and then in the recycling of post-consumer plastic of WEEE there is a pressing need for rapid measurement technologies for simple identification of the various commercial plastic materials and of the several contaminants, to improve the recycling of such wastes.This research is focused on the characterization and recycling of two types of plastics, namely plastic from personal computer (grey plastic) and plastic from television (black plastic). Various analytical techniques were used to monitor the compositions of WEEE. Initially, the chemical structure of each plastic material was identified by Fourier transform infrared (FTIR) spectroscopy and differential scanning calorimetry (DSC). Polymeric contaminants of these plastics, in particular brominated flame retardants (BFRs) were detected in grey plastics only using different techniques. These techniques are useful for a rapid, correct and economics identification of a large volumes of WEEE plastics.     

Resource-availability scenario analysis for formal and informal recycling of end-of-life electrical and electronic equipment in China

In strategic end-of-life electrical and electronic equipment (EoL EEE) management, it has become important to not only avoid the negative environmental impacts but also enhance the positive effects of secondary resource utilization. This is especially true in emerging countries such as China, where medium- to long-term increases in the amount of EoL EEE generation are projected. This study aims to assess the resource availability potential for EoL EEE recycling based on penetration scenarios for formal and/or informal treatment options in China. We categorized substances contained in EoL television sets and personal computers into environmental, resource, and economic aspects under consideration of product transitions. Barium and copper have a high negative potential impact on human health and/or the ecosystem. Focusing on metals with a high resource potential, the resource availability is assessed under different treatment options using characterization factors identified through a life-cycle impact assessment method, the ReCiPe 2008. The results suggest that copper and lead recycling could alleviate the increase in mining costs of resource utilization. Scenario analysis for penetration of formal and informal recycling options indicated that the difference in the alleviated mining costs between the status quo and short-term transition projections until 2030 corresponds to 2.1–2.4 billion dollars.

Chemical hazards associated with treatment of waste electrical and electronic equipment

This review paper summarizes the existing knowledge on the chemical hazards associated with recycling and other end-of-life treatment options of waste electrical and electronic equipment (e-waste). The hazards arise from the presence of heavy metals (e.g., mercury, cadmium, lead, etc.), flame retardants (e.g., pentabromophenol, polybrominated diphenyl ethers (PBDEs), tetrabromobisphenol-A (TBBPA), etc.) and other potentially harmful substances in e-waste. If improperly managed, the substances may pose significant human and environmental health risks. The review describes the potentially hazardous content of e-waste, examines the existing e-waste management practices and presents scientific data on human exposure to chemicals, workplace and environmental pollution associated with the three major e-waste management options, i.e., recycling, incineration and landfilling. The existing e-waste management practices and associated hazards are reviewed separately for developed and developing countries. Finally, based on this review, the paper identifies gaps in the existing knowledge and makes some recommendations for future research.
