Important results from the project
The project´s goals were to develop cost-effective carbon fiber electrodes to recover valuable metal ions from wastewater for sustainable and effective resource recovery and environmental remediation. The project successfully advanced the development of carbon fiber electrodes, and significant progress was made in optimizing the parameters for metal ion recovery and characterization of carbon fibers in different environments, especially under low pH conditions.
Expected long term effects
The development of carbon fiber electrodes for metal ion recovery will significantly facilitate metal extraction from wastewater and mining residues, contributing to a more sustainable and circular economy. With further development, the sensitive and unique electrical nature of the carbon fibers will enable continuous electrical monitoring of the metal extraction, making it the first electroactive system for both metal extraction and monitoring.
Approach and implementation
The project aimed to develop effective carbon fiber electrodes for metal ion recovery from different wastewater. Despite delays due to technical challenges and a change in project leadership, the project made significant progress in electrode optimization. Key milestones were achieved, including published research and successful collaboration between KTH, IVL, and industrial partners. The teamwork remained strong, and the project contributed valuable insights for sustainable resource recovery.
