Abstract A new pulverization method to reduce the volume of waste printed circuit boards is reported. About 50% of printed circuit boards with integrate circuits (ICs) could be pulverized by our method in one 20-min batch,but boards without ICs could not be pulverized. By repeating the process three times,about 95% of printed circuit boards

Among e-waste, waste printed circuit boards (PCBs) are attracting more attention. Accounting for 4 wt% of total e-waste in Australia, waste PCBs pay off 40% (US$ 150 million) of metal recovery value from all e-waste (Golev and Corder, 2017). Embedded within waste PCBs are valuable metals (Au, Ag, Ni and Cu) with a positive market value …

PCBs (printed circuit boards) are a significant proportion of all the e-waste including waste TVs, MP3 players, PCs, laptops, and appliances; accounting for 3–5% of the total mass (Faraji et al., 2018; Mostafavi et al., 2018).The main function of PCBs is to provide connections between the different components of the electronic devices.

It's estimated that the Waste Electrical and Electronic Equipment (WEEE) and e-waste generated in 2021 was 57.5 million metric tons (Mt) [8]. About 42% of WEEE and e-waste comprises waste printed ...

Among the categories of E-waste, waste printed circuit boards (WPCBs) are considered the most complex waste materials, owing to their various constitutes, such as plastics, capacitors, wiring, and ...

There is a big waste generation nowadays due to the growing demand for innovation and the fact that more and more products have a reduced lifetime, increasing the volume of dumps and landfills. Currently, one of the segments of large volume is the technology waste, which reflects on the printed circuit boards (PCBs) that are the …

Resource shortages and metal demand continuously increase, and the massive quantities of waste printed circuit boards (WPCB) generated make resource recycling and environmental sustainability necessary paths. Pyrolysis is a practicable and promising pathway to lessen the environmental burden through the conversion of WPCB …

The low bioleaching efficiency of Acidithiobacillus ferrooxidans results in its sparse industrial application for metal extraction from waste printed circuit boards (WPCBs). To improve the bioleaching efficiency of Acidithiobacillus ferrooxidans, we propose the use of mechanical activation to dispose WPCBs prior to performing …

Mechanical treatment methods, pyrometallurgy and hydrometallurgy have been developed to be applied for WPCB recycling ( Mir and Dhawan, 2022 ). However, …

One of this WEEE is printed circuit boards (PCBs). PCBs form about 3% by weight of total amount of electronic waste ( Guo et al., 2008 ). Recyclers use different methods to reclaim the metals in PCBs with high purity, which can be sold at high price while enormous amount of nonmetallic materials in PCBs (up to 70 wt%) present an especially ...

Printed circuit boards (PCBs) provide electrical interconnections between elements and report for approximately 4% of all electronic waste 26,27. Waste Printed Circuit Boards (WPCBs) are an ...
