“…A similar situation exists in the case of separation of non-ferrous metals, which in fragmentation of 0.1 mm have a high commercial value due to granulation facilitating further fractionation process. Considering the cost effectiveness of semi-automatic line modernization in LCA and ROI algorithm there was achieved return on investment after 3-5 years, depending on market prices of obtained raw materials, what is confirmed also in works of Hurka and Malinowski [14], Grzesik-Wojtysiak and Kuklinski [15] and Debnatha et al [16]. This time can be shortened if we consider the entire stream of WEEE reaching the installation because the life cycle analysis focuses only on the 3 most popular devices.…”

The authors introduced automatic processing line for electrical and electronical equipment wastes as an alternative for semi-automatic WEEE lines. The efficiency of semi-automatic line was characterized for small WEEE with LCA and AHP algorithms. The problem nodes showed by algorithms was optimized and replaced by automatic devices. Optimized automatic WEEE processing line generated `groups of sources with min. 98 wt% purity. Comparison of the results obtained for the semi-automatic line to the automated line, 83-times increase in productivity was observed. Streszczenie. W artykule przedstawiono automatyczną linię do przetwarzania odpadów elektrycznych i elektronicznych (WEEE) jako alternatywę dla linii półautomatycznych. Wydajność linii półautomatycznej charakteryzowała się małą wydajnością przetwarzania WEEE. Do oceny możliwości poprawy jej wydajności wykorzystano algorytmy LCA i AHP. Węzły problemów wskazane przez algorytmy zostały zoptymalizowane i zastąpione przez urządzenia automatyczne. Zoptymalizowana automatyczna linia do przetwarzania WEEE generuje materiały o minimalnej czystości 98% wag. Porównanie wyników uzyskanych dla linii półautomatycznej i linii zautomatyzowanej wykazało 83-krotny wzrost wydajności. (Możliwości automatyzacji ręcznej linii do demontażu zużytego sprzętu elektronicznego).

“…WEEE contains both hazardous and precious components, and is a rapidly growing waste stream [3][4][5]. The responsible collection and recycling of WEEE reduces environmental harm [6,7] and facilitates the recovery of valuable materials [8][9][10], including rare earth elements and other critical raw materials (e.g., indium and gallium) that are of vital importance for modern economies [11][12][13][14].…”

Waste electrical and electronic equipment (WEEE) is difficult to sustainably manage. One key issue is the challenge of planning for WEEE flows as current and future quantities of waste are difficult to predict. To address this, WEEE generation and gross domestic product (GDP) data from 50 countries of the pan-European region were assessed. A high economic elasticity was identified, indicating that WEEE and GDP are closely interlinked. More detailed analyses revealed that GDP at purchasing power parity (GDP PPP) is a more meaningful measure when looking at WEEE flows, as a linear dependency between WEEE generation and GDP PPP was identified. This dependency applies to the whole region, regardless of the economic developmental stage of individual countries. In the pan-European region, an increase of 1000 international $ GDP PPP means an additional 0.5 kg WEEE is generated that requires management.

“…The use of tantalum results in a very thin dielectric layer, results in higher capacitance and very low equivalent series resistance (ESR) values. The tantalum capacitors are having excellent stability characteristics (Debnath et al, 2016). Even a small overvoltage can lead to tantalum failures, known as field crystallization (Varde, 2010;Huang et al, 2019).…”

PurposeCapacitors are one of the most common passive components on a circuit board. From a tiny toy to substantial satellite, a capacitor plays an important role. Untimely failure of a capacitor can destruct the entire system. This research paper targets the reliability assessment of tantalum capacitor, to reduce e-waste and enhance its reusable capability.Design/methodology/approachThe residual lifetime of a tantalum capacitor is estimated using the empirical method, i.e. military handbook MILHDBK2017F, and validated using an experimental approach, i.e. accelerated life testing (ALT). The various influencing acceleration factors are explored, and experiments are designed using Taguchi's approach. Empirical methods such as the military handbook is used for assessing the reliability of a tantalum capacitor, for ground and mobile applications.FindingsAfter exploring the lifetime of a tantalum capacitor using empirical and experimental techniques, an error analysis is conducted, which shows the validity of empirical technique, with an accuracy of 95.21%.Originality/valueThe condition monitoring and health prognostics of tantalum capacitors, for ground and mobile applications, are explored using empirical and experimental techniques, which warns the user about its residual lifetime so that the faulty component can be replaced in time.
