“…Maximum metal recoveries of 99.2%, 50.4%, and 89.4% for lithium, cobalt, and nickel, respectively, are achieved at an optimum inoculum level of 3/2, optimal conditions of 36.7 g/L iron sulfate, 5.0 g/L sulfur, and an initial pH of 1.5. Dolker et al [76] used a combination of Bacillus lysine-citric acid for the recovery of spent LIBs. The citric acid method is used to separate copper and aluminum foils from the black powder.…”

With the rapid development of the electric vehicle industry in recent years, the use of lithium batteries is growing rapidly. From 2015 to 2040, the production of lithium-ion batteries for electric vehicles could reach 0.33 to 4 million tons. It is predicted that a total of 21 million end-of-life lithium battery packs will be generated between 2015 and 2040. Spent lithium batteries can cause pollution to the soil and seriously threaten the safety and property of people. They contain valuable metals, such as cobalt and lithium, which are nonrenewable resources, and their recycling and treatment have important economic, strategic, and environmental benefits. Estimations show that the weight of spent electric vehicle lithium-ion batteries will reach 500,000 tons in 2020. Methods for safely and effectively recycling lithium batteries to ensure they provide a boost to economic development have been widely investigated. This paper summarizes the recycling technologies for lithium batteries discussed in recent years, such as pyrometallurgy, acid leaching, solvent extraction, electrochemical methods, chlorination technology, ammoniation technology, and combined recycling, and presents some views on the future research direction of lithium batteries.

“…Sinha et al [ 85 ] developed a novel biorecovery process followed by electrochemical treatment to recover copper, achieving 92.7% Cu recovery. Dolker et al [ 86 ] applied the chemical-biological hybrid systems to the bioleaching process, increasing Li leaching by 25% and cobalt biosorption by 98%. Gomes et al [ 87 ] linked electrodialytic remediation with microbial metabolism, higher mobilization of metals was observed when associating both methods, with higher metal concentrations in both anode and cathode compartments, in particular for Cu and Cr.…”

The rapid pace of innovations and the frequency of replacement of electrical and electronic equipment has made waste printed circuit boards (WPCB) one of the fastest growing waste streams. The frequency of replacement of equipment can be caused by a limited time of proper functioning and increasing malfunctions. Resource utilization of WPCBs have become some of the most profitable companies in the recycling industry. To facilitate WPCB recycling, several advanced technologies such as pyrometallurgy, hydrometallurgy and biometallurgy have been developed. Bioleaching uses naturally occurring microorganisms and their metabolic products to recover valuable metals, which is a promising technology due to its cost-effectiveness, environmental friendliness, and sustainability. However, there is sparse comprehensive research on WPCB bioleaching. Therefore, in this work, a short review was conducted from the perspective of potential microorganisms, bioleaching mechanisms and parameter optimization. Perspectives on future research directions are also discussed.
