Abstract
The escalating global discard of electronic devices has propelled the issue of e-waste disposal and recycling to the forefront. In the E-waste, presence of hazardous materials like lead, mercury, and cadmium, poses significant environmental and health risks if not managed properly. However, conventional recycling methods including open burning and acid baths worsen environmental degradation rather than mitigating it. Similarly, traditional metal extraction techniques like open-pit mining and smelting contribute to habitat destruction, air and water pollutions. To combat these challenges, bioleaching appears as a promising solution for recycling e-waste and extracting metals sustainably. Bioleaching involves the use of bacteria and other microorganisms to dissolve metals from ores or electronic waste, presenting a more environment friendly alternative to conventional methods. By harnessing microbial action, bioleaching offers a pathway to recover valuable metals such as copper from e-waste. Role of specific acidophilic bacteria in catalyzing metal extraction emphasizes the importance of perfecting environmental conditions for microbial activity. Furthermore, insights into mine water use for metal extraction underscores the comprehensive approach of bioleaching in waste management. Scaling up the bioleaching process for organic waste recycling requires optimization of microbial consortia, process engineering, and effective nutrient management. In conclusion, bioleaching is a sustainable approach to ameliorate the e-waste crisis and help in metal extraction from solid wastes and ores. By embracing bioleaching and advancing its technologies, we can move towards a circular economy, minimizing environmental impact while maximizing resource recovery.
