An innovative and eco-friendly approach to recover gold (and copper) from gold fingers of waste printed circuit boards

Sousa P., Martelo L., Bastos M., Marques A., (Corresponding) Soares H.

Topic:

Sustainable supply of raw materials

Recycling waste printed circuit boards (WPCBs) is a complex problem worldwide and sustainable technologies are required. So, this work aims to offer an innovative (an European patent was submitted, EP 20216239.2 1) and more sustainable solution to recover high-value materials (gold and copper) from...Read more

Topic:

Sustainable supply of raw materials

Results are reported herein of a study aiming to develop an integrated process for valorizing liquid digestate (LD) from an industrial anaerobic digestion (AD) plant treating dairy-processing effluents. The investigated approach involves LD treatment by nanofiltration (NF) membranes, at pilot-scale...Read more
