“…Jonkers et al [ 58 ] performed an LCA study to compare the environmental impacts of BFRs and halogen-free flame retardants (HFFRs) in an electronic product over the whole life cycle and demonstrated that improper treatment of WEEE has the highest impact compared with different waste treatment options. Jaunich et al [ 59 ], focusing on CO 2 emissions released in all steps of the recovery and recycling processes, developed a holistic framework to estimate the cost and environmental impacts associated with e-waste management.…”

Plastic materials account for about 20% of waste electrical and electronic equipment (WEEE). The recycling of this plastic fraction is a complex issue, heavily conditioned by the content of harmful additives, such as brominated flame retardants. Thus, the management and reprocessing of WEEE plastics pose environmental and human health concerns, mainly in developing countries, where informal recycling and disposal are practiced. The objective of this study was twofold. Firstly, it aimed to investigate some of the available options described in the literature for the re-use of WEEE plastic scraps in construction materials, a promising recycling route in the developing countries. Moreover, it presents an evaluation of the impact of these available end-of-life scenarios on the environment by means of the life cycle assessment (LCA) approach. In order to consider worker health and human and ecological risks, the LCA analysis focuses on ecotoxicity more than on climate change. The LCA evaluation confirmed that the plastic re-use in the construction sector has a lower toxicity impact on the environment and human health than common landfilling and incineration practices. It also shows that the unregulated handling and dismantling activities, as well as the re-use practices, contribute significantly to the impact of WEEE plastic treatments.

There is no clear direction in the management of electrical and electronic waste products (e-waste), as there are no regulations on ways to do so. This research attempts to understand the trade-off between economic value and environmental effects of the current disposal of e-waste to find ways to optimize waste management, focusing on cellphones, television CRTs, desktop computers, and air conditioners. A Life Cycle Assessment (LCA) is a tool that can analyze various influences, e.g., environmental, costs, and value added. Under the e-waste management status quo, most household e-wastes are kept in houses because owners do not know where to discard them. In addition, informal sectors, such as domestic farmers or workers, have been involved actively for more than a decade, leading to poor management standards for both health and the environment. The logistics are inefficient because the dismantling communities and recycling industry are far apart. Most e-waste is generated, and most recycling industries are located, in the Central region (the richest areas), while the dismantling communities are located in the Northeastern region (the poorest areas). Further, LCA and LCC of e-waste are sensitive to transportation, and not all e-waste parts can be recycled within the country. High-tech mineral extraction cannot be practiced in the country, and thus, circuit boards and batteries are exported for recycling. To promote a circular economy, e-waste management regulations should be implemented and a full recycling industry should be established in the country.

“…The quality of recycling of e-waste from end-of-life computers was analyzed by [45]. The life-cycle perspective was approached by [83], which presented a quantitative framework to estimate life-cycle impacts and costs associated with e-waste management, with well-defined steps. Data from the State of Washington's EPR program were used to test the framework, involving the activities of collection, transportation, processing, and disposal.…”

How to Assess Reverse Logistics of e-Waste Considering a Multicriteria Perspective? A Model Proposition

As e-waste exponentially increases on a global scale, some legislation and plans to implement reverse logistics have arisen in some countries. While reverse logistics is already well consolidated in developed countries, it is still in a state of infancy in developing countries. In this article, we propose a theoretical model to assess reverse logistics, based on a multicriteria decision aid perspective. This was done while considering a context in which the implementation of the reverse logistics of e-waste is at the beginning. To show the main characteristics of the literature and obtain the model’s inputs, we conducted a systematic literature review to help us understand the main criteria and methods used for this purpose. Then, we illustrated the use of the proposed model with a numerical example. This paper contributes to the current body of research, and aims to assist practitioners within the field of reverse logistics by systematizing the knowledge related to this issue, and offering a model that can guide the decision-making. This model differentiates from others already published because it uses the probabilistic composition of preferences (PCP) method, which does not require the assignment of weights. The model can also be used while considering the preferences of several decision-makers, therefore covering several points of view and providing a more holistic view of the decision problem.
