The research project HYDROPCB in which the School of Eng. Mines – Metallurgists of NTUA and Ecoreset participated and has been funded by the General Secretariat for Research and Technology under the action RESEARCH – CREATE – INNOVATE, was successfully completed.
For this project, a hydrometallurgical method for the recovery of gold and silver from Printed Circuit Boards was developed and confirmed on a pilot scale, which was accompanied by treatment of the produced wastewater with microorganisms for zero discharge.
The proposed method promotes circular economy principles for recovering precious metals from e-waste and is suitable for small and medium-scale installations.
The scientific conclusions of the project are summarized in a paper to be published in the Journal of Environmental Management and can be found at the following link:
