E-waste

Italian and Japanese researchers have developed a novel method to free copper wire from its PVC coating, by treating electric cables with microwaves. The technique could go a long way towards helping tackle the growing problem of e-waste.

Using a proprietary chemical process pioneered by Canadian firm Excir, England's The Royal Mint has begun mining old circuit boards from electronic devices for gold and converting what's harvested into attractive, if pricey, jewelry.

A new method for recovering high-purity gold from discarded electronics is paying back US$50 for every dollar spent, according to Swiss researchers – who found their all-important gold-filtering substance in cheesemaking, of all places.

The disposable nature of modern gadgetry is leading to a worrying e-waste problem. To highlight the issue, Envision Racing and artist Liam Hopkins teamed up to create a Formula E Gen3 racecar built from discarded phones, laptops, vapes and other tech.

Looking to tackle a significant part of our huge e-waste problem, Jiva has developed a PCB substrate that breaks down in water for easier recovery of materials. The startup is now partnering with manufacturers to demo and evaluate the Soluboards.

Discarded electronics can be a gold mine – literally. Researchers have developed an efficient new way to use graphene to recover gold from electronic waste, without needing any other chemicals or energy.

E-waste is a major environmental hazard, full of valuable metals. Engineers at Rice University have now shown that precious metals and rare earth minerals can be recovered by flash-heating ground-up electronics with a zap of electricity.

Eyeing solutions to our e-waste problem, engineers have developed the world's first fully recyclable printed electronics, demonstrated in a transistor that can be reduced to its original building blocks with the help of baths and sound waves.

Californian startup Framework says that it was founded to provide quality products that can be customized, upgraded and repaired with ease. The company has today launched a 13.5-inch laptop aimed at ticking all of those boxes.

While there are now many appliances that can be controlled via the internet, each one of those has to incorporate Internet of Things (IoT) electronics. Engineers have now created a system that moves those electronics to the home's wall outlets.

A study by IBM has revealed that many discarded laptop batteries have the potential to provide enough power to keep the lights running in homes in poorer countries. The team conducted a study to test the viability of the idea, with work now focused on streamlining a prototype system.

Italian product designer Simone Rebaudengo has created a connected toaster that becomes unhappy when it goes unused, drawing attention to opportunities for e-waste to be reduced.
