“…Moreover, it was not until June 2019 when the EU clarified their determinations on the regulation of persistent organic pollutants (POPs), that many non-hazardous WEEE items would be reclassified as hazardous and become subject to the Hazardous Waste Regulations 2005 (Official Journal of the European Union, 2019). Moreover, in low-and moderateincome countries, approximately 90 % of e-waste disposal and recycling activities are undertaken by informal sector workers (Pathak et al, 2019). In India, for instance, 97 % of total e-waste generated is handled by informal recycling yards in major cities like Delhi, Mumbai, Hyderabad, and Bangalore (Rao et al, 2017).…”

Managing electronic waste or e-waste in Jakarta Province, Indonesia, is essential to support sustainable development goals (SDGs). E-waste contains toxic materials and is harmful to the environment while having the potential for a circular economy if appropriately managed. This study aims to analyze electronic waste management, formally originating from households in Jakarta Province, from the aspects of the e-waste collection mechanism, the type of e-waste, the amount of e-waste, and the flow of e-waste information using a descriptive method. The research findings are that the Jakarta Regional Government collects e-waste through three mechanisms: e-waste direct pickup (35.5%), e-waste drop box (0.6%), and e-waste temporary garbage collection (63.9%). The total amount of e-waste managed formally was 33,289 kg in 2021. In practice, there are five types of e-waste: television, lights, batteries, printer cartridges, and other e-waste. The effectiveness of the e-waste collection process needs improving. The amount of e-waste collected can be increased. One of the robust recommendations for improving e-waste management in Jakarta is integrating innovative digital platform-based technology and multi-actor collaboration. This research supports preliminary data and information on the circular economy’s potential and the formulation of specific regulations on e-waste in Indonesia.

“…8 Electronic (e-)waste is one of the fastest increasing waste streams (>50 Mt in the year 2019) whose disposal and effective management is a global challenge. 9 The strata of metals, including many of the critical metals, and their associated economic values (as summarized in Table 1) along with the availability across the geopolitical barriers are the key points rendering ewaste as one of the primary candidates to be recycled for metals recovery. 10,11 Printed circuit boards (PCBs) are the essential components in modern electronic devices and they contain 3-6 wt% of metallic fraction.…”

“…Many recycling routes comprised of pyro-metallurgy, hydrometallurgy, or including both techniques have been explored in conventional practices. 9,12 The problems associated with a pyrometallurgical process has been identified to be high energy consumption, large gaseous emissions (like furans), and a huge generation of secondary waste (like slag). 10 On the other hand, hydrometallurgical recycling required a large amount of chemicals.…”

Critical metals are key raw materials for new generation clean energy production. The extraction of critical metals often follows the difficult processing of primary ores and they are many times recovered as the companion metals. With the depletion of primary reserves, the focus has now shifted to processing the urban mines, like electronic (e-)waste. Among the different types of e-waste, the waste printed circuit boards (WPCBs) are the major reservoir of high-value critical metals and are usually treated by the traditional pyro-and/or hydro-metallurgical techniques. However, the application of microbial activities in metals recycling is rapidly emerging as a green technology in comparison to smelter or chemical processing. The application of microorganisms (bacteria/fungi) in WPCBs' recycling is being increasingly explored in order to meet the parallel objectives of resource recovery and pollution mitigation. Therefore, the present article assesses the current frontiers in bioleaching of critical metals from WPCBs and contains discussions on process fundamentals, challenges, and perspectives. The applicability of microbial recycling of WPCBs at a higher scale in terms of a circular economy and urban mining notion, the techno-economic analysis, and environmental sustainability in comparison to the chemical processing route are also discussed.
