Printable recyclable smartphones - the latest breakthrough in green tech

The world’s first fully recyclable, printed electronics are being developed in the US to combat gadget waste.

Scientists at Duke University have created a fully functional transistor made out of three carbon inks that can easily be 3D-printed on to paper to replace the unsustainable silicon chips many devices use.

This new technique presents promising solutions to the tech industry’s hardware production “epidemic”. Transistors have been a historically complex component for scientists to try and reproduce and dispose of in an environmentally-conscious way. An average smartphone needs millions of the tiny devices to function.

Creating recyclable transistor technology of this kind has been ushered along by the development of ‘wood-derived insulating dielectric ink’ called nanocellulose.

“While people have long known about its potential applications as an insulator in electronics, nobody has figured out how to use it in a printable ink before. That’s one of the keys to making these fully recyclable devices functional.”

I suppose the iPhone battery life can’t get any worse, so…

This is amazing. Now they need to figure out a way to replace Lithium batteries because Lithium harvesting is literally destroying the planet lol
