Water soluble circuit boards are an e-waste game changer

pcgamer.com:

We're all aware that e-waste is a big problem, at this point. When they're not strewn across our own floors, mountains of hard drives are being unnecessarily wasted every year and the figures for how much e-waste is generated per-year are startling. 

But rather than watching piles and piles of the stuff grow, there are companies out there doing something about it. One great way to tackle e-waste is to recycle electronic parts, since they're an untapped source of rare Earth materials. Then, of course there's the potential for a complete change in materials.

Rather than coming up with new ways to fix things after the fact, semiconductor manufacturer Infineon technologies AG has gone back to the source itself, and is looking to utilise a plant-based PCB design known as the Soluboard. Designed by a British start-up Jiva Materials, not only do these eco boards «have a significantly lower carbon footprint than traditional glass fibers», they also dissolve in water (via ComputerBase).

The company has been working in accordance with the circular economy of the European Commission's Green Deal, and the WEEE (Waste Electrical and Electronic Equipment) Directive, to research new ways to tackle e-waste, all without losing out on precious materials. What's great about this design is that dissolving these boards in water doesn't just break them down so their other valuable components are lost to the ether. 

«Adopting a water-based recycling process can lead to greater efficiencies in recovering valuable metals,» says Jonathan Swanston, CEO and co-founder of Jiva Materials.
