Suffering guilt at your gadget gluttony? I know it well, which is why I was aflutter last night at a Dana Centre demo of gadgets that can break into their component parts - a screen, keypad, battery and circuit board in the case of a phone - just by being exposed to heat or magnetism. To help me and my layman science understand, Habib Hussein from Ideas 3 gave me a thin piece of wire and asked me to bend it any shape I liked.
Three seconds of his cigarette lighter later and it had unravelled back into its original straight shape.
A cool party trick, certainly, but just a small part of a relatively new tech dubbed active disassembly. In short, using memory metals and more complicated tech, it makes products a cinch to recycle at the end of their life: instead of painstakingly having to take stuff apart - which equals time and money - recycling plants can automate a lot of the process. Habib reckons the first real world products that'll actively disassemble are cars, with several manufactuers keen on the idea.
