Heavy metal pollution poses significant environmental and public health risks due to its persistence and toxicity. Traditional remediation methods, such as chemical precipitation and soil excavation, often prove costly and inefficient for large-scale applications. This has driven the development of innovative technologies aimed at more effective and sustainable heavy metal management. Recent advancements include emerging catalytic strategies that leverage external fields (electric, magnetic, mechanical, and thermoelectric) to enhance the removal efficiency of heavy metals from water resources. These methods, often coupled with photocatalysis, offer promising avenues for improving environmental sustainability. Phytoremediation(including phytostabilization, phytoextraction, and phytovolatilization) is another green technology that utilizes hyperaccumulator plants and their associated microorganisms to stabilize, transfer, or degrade heavy metals in contaminated soils and water. This method is cost-effective, adaptable, and environmentally friendly. Membrane technologies have shown significant potential in wastewater treatment. Techniques such as ion exchange, adsorption, and advanced filtration systems are being optimized to selectively remove heavy metal ions from industrial effluents. There is another technological innovation that has become important in recent years: Recycling Technologies. New recycling methods, such as suspension magnetization roasting and hydrometallurgical processes, are transforming waste into valuable resources. These innovative approaches not only enhance the efficiency of heavy metal remediation but also contribute to the development of sustainable environmental management practices. Future research should focus on overcoming current limitations and scaling these technologies for broader application.
