amic capacitors, processors, integrated circuits, and tantalum capacitors (Mir and Dhawan 2022). The recovery of base and precious metals from PCBs is often studied, while studies on tantalum (Ta) recov-ery are limited, with a recycling rate of <1% (Ramon et al. 2020). Most recycling studies empha-sise the metal recovery from bare PCBs without giv-
Advanced recycling and identification system for discarded capacitors
The disposal of discarded capacitors has gradually raised concerns among the public and environmental organizations(Y. Jinglei et al., 2009). On one hand, these discarded capacitors contain hazardous substances such as heavy metals and toxic chemicals, which, if improperly handled, can lead to severe environmental pollution.

Aluminum Electrolytic Capacitors
An Aluminum Electrolytic Capacitor is a type of capacitor that contains just a few essential parts: aluminum foil, electrolytic paper, an aluminum oxide layer, and two terminals (a cathode and an anode). Aluminum Electrolytic Capacitors work by using the polarity between the two terminals to maintain high capacitance within the component.

How-To: Air-Variable Capacitor From Scrap Aluminum
This lovely hand-made component, built as part of a crystal radio set Instructables user Jezan assembled for his son, started out as a sheet of 1.5 mm aluminum that looks like it may have come from the side of an old file cabinet. Jezan used minimal tools, laying out the part profiles by hand with a ruler and a compass improvised from a scrap of wood and

Should I discard my inventory of old electrolytic capacitors?
An ideal capacitor has a leakage current of zero, but only the best capacitors approach that ideal. Electrolytic caps are far from ideal. If you leave the capacitor in the charging setup, you may find that the leakage current drops for some time after hitting the voltage limit, then stabilizes.

Recycling of Discarded Tantalum Capacitors for Metal Recovery
Discarded tantalum capacitors contain 30–35 wt.% tantalum, which is tightly encapsulated in an epoxy housing. Tantalum recycling is necessary due to scarcity, finite resources, and geopolitical constraints. Tantalum capacitors consist of Ta metal anodes compressed into a sintered core which is coated with a layer of MnO. 2

The phase analysis of the capacitor revealed Ta, MnO 2, Ag, SiO 2, and minor fractions of Sn and Ag 2 O (Fig. 1a). The SEM–EDS analysis of the crushed capacitors showed a strong association between the non-metal (C, Si) and metal (Mn, Ta) fractions (Fig. 1b). Since SC is a concentrated source of Ta, it is recommended to recover it separately
