Among other components, printed circuit boards usually have a non-conductive layer that serves as a substrate for electronic components. It consists of two ingredients: glass fiber and epoxy resin, ...

Researchers at the school have developed a new kind of printed circuit board (PCB) that's a snap to recycle. It even does half the work for you by decomposing into a reusable jelly on command.

Once such a "vPCB" (vitrimer printed circuit board) has reached the end of its use, it will be sent to a recycling facility and immersed in an organic solvent which has a relatively low boiling ...

Recyclable vitrimer-based printed circuit boards for sustainable electronics. Nature Sustainability, 2024; DOI: 10.1038/s41893-024-01333-7 ...

From left: Amit Humar and Maria Holuszko have developed a process to separate fiberglass from resins in printed circuit boards. While most electronics recyclers recover metals from electronic scrap ...

Ground up into a powder, printed circuit boards from these products could sponge up another type of pollution —toxic heavy metals in water (Environ. Sci. Technol. 2013, DOI: 10.1021/es4001664).
