  • New Tech Makes Circuit Board That is 90% Recyclable

    Electronic waste is becoming more of a troubling problem with the global volume of electronic waste expected to grow by 33% in the next four years. According to the UN’s ‘Step initiative’ nearly 50m tonnes of e-waste was generated worldwide last year, about 7kg for every person on the planet, as old devices were discarded to sit in landfills.

    Even when devices are recycled responsibly, circuit boards in everyday electronics are based on reinforced epoxy glass and solder, which makes it hard for them to be taken apart safely. Continue reading
