The transition to renewable energies and electric vehicles has triggered an unprecedented demand for metals. Sustainable development of these technologies relies on effectively managing the lifecycle critical raw materials, including their responsible sourcing, efficient use, recycling. Metal recycling from electronic waste (e-waste) is paramount importance owing ore-exceeding amounts elements high toxicity heavy metals organic pollutants in e-waste natural ecosystem human body. Heterotrophic microbes secrete numerous metal-binding biomolecules such as acids, amino cyanide, siderophores, peptides, biosurfactants which can be utilized eco-friendly profitable metal In this review paper, we presented a heterotrophic organisms biomining, current barriers hampering industrial application acid bioleaching biocyanide leaching. We also discussed how challenges surmounted with simple methods (e.g., culture media optimization, separation microbial growth extraction process) state-of-the-art biological approaches artificial community, synthetic biology, metabolic engineering, advanced fermentation strategies, biofilm engineering). Lastly, showcased emerging artificially synthesized biosurfactants) derived heterotrophs potential inexpensive, low-impact, selective recovery solutions.

With the rapid technological development in 21st century, increasing consumption of electronic devices has led to a rise generation waste electrical and equipment (WEEE) due disposal considered obsolete. A significant portion these wastes contain printed circuit boards (PCBs), which serve as substrates for connection microchips, resistors, capacitors, other components. These are composed various materials, primarily metals such copper. Thus, this study investigated recovery copper from PCB (WPCBs) computers through alkaline leaching, using EDTA hydrogen peroxide at temperatures 40 °C, 60 80 with concentration 0.6 mol/L varying particle sizes. Using UV-VIS spectrophotometer, it was observed that extraction process temperature °C achieved rate 78.6% particles smaller than 0.177 mm after 180 min, following Avrami kinetic model. The results highlight potential complexing agent extraction, positioning promising technique reduce environmental contamination recover strategic resources urban mining WEEE.

Adsorption stands out as a leading wastewater treatment method for ion removal or recovery. Polymeric fibers, notably electrospun ones, are gaining prominence due to their high capacity and easy Electrospinning offers cost-effective means produce fibers with large surface area adsorption capacity. These can be further functionalized chemical substances acting specific ligands metal ions, bolstering capabilities. In this study, dithioester-functionalized were synthesized an alternative conventional sorbents palladium recovery from acidic chloride solutions, similar those used in hydrometallurgical processes platinum group (Pd, Pt, Rh···) spent catalysts. Fibers identical composition but varying morphology examined assess impact on efficiency (i.e., beads-free beads-on-string morphologies). Experimental investigations involved model solutions concentration, temperature, acidity (adjusted HCl content), salinity NaCl), utilizing both pure fibers. results demonstrate enhanced at lower temperatures 0.1 M HCl, negligible influence solution salinity. Moreover, polymeric exhibit highly efficient Furthermore, under optimal conditions, starting 80 mg/L solution, 95% of achieved sorbent dosage below 4 g/L The data well described by the Langmuir isotherm At same time, contribution dithioesters has been separately accounted describe behavior Thermal also investigated.
