Abstract
Solid waste containing valuable elements has the potential to be a valuable secondary resource. However, the common methods (hydrometallurgy and pyrometallurgy) used to recover these elements from solid waste consume large amounts of energy and pollute the environment. Therefore, it is crucial to explore a low energy-consuming, efficient, and environmentally friendly method for recovering these valuable elements. One promising approach is to utilize an applied electric field as a reaction driver to enhance conventional chemical leaching. By using electrons as a green leaching agent or leaching medium instead of chemical agents, the recovery of valuable elements can be significantly improved while reducing the consumption of chemical reagents and environmental pollution. This paper provides a detailed and categorized discussion on the application of different forms of electrochemical methods for the effective recovery of valuable elements from various forms of solid waste.
期刊介绍:
The Journal of Environmental Chemical Engineering (JECE) serves as a platform for the dissemination of original and innovative research focusing on the advancement of environmentally-friendly, sustainable technologies. JECE emphasizes the transition towards a carbon-neutral circular economy and a self-sufficient bio-based economy. Topics covered include soil, water, wastewater, and air decontamination; pollution monitoring, prevention, and control; advanced analytics, sensors, impact and risk assessment methodologies in environmental chemical engineering; resource recovery (water, nutrients, materials, energy); industrial ecology; valorization of waste streams; waste management (including e-waste); climate-water-energy-food nexus; novel materials for environmental, chemical, and energy applications; sustainability and environmental safety; water digitalization, water data science, and machine learning; process integration and intensification; recent developments in green chemistry for synthesis, catalysis, and energy; and original research on contaminants of emerging concern, persistent chemicals, and priority substances, including microplastics, nanoplastics, nanomaterials, micropollutants, antimicrobial resistance genes, and emerging pathogens (viruses, bacteria, parasites) of environmental significance.
