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

Waste Printed Circuit Boards (WPCBs) as a potential source for the recovery of rare earth elements through bioleaching.

(Corresponding) Gonzalez Baez A., Pantoja Muñoz L., Garelick H., Purchase D.
Topic: 
Electric and electronic waste
Rare earth elements (e.g., neodymium, dysprosium and praseodymium) have contributed to the miniaturization, energy efficiency, durability, and high speed of many technology gadgets. Due to their electric conductivity, magnetic, luminescence and optical properties, rare earth elements (REE) are...Read more
