After my epic struggle to find an environmentally friendly way to dispose of my obsolete printer last year, I viewed the growing stack of used CDs and DVDs on my desk with some alarm. These bits of plastic and metal are a necessary evil for transporting data and images in my industry, but once I've finished with them the information is immediately out of date and the discs can't be reused.
The local council just dumps them in landfill; they can't be recycled with the tin cans and plastic bottles because they contain both metal and plastic. A Google search led me to this fun site -- I might have to make one of those hovercrafts -- but I've got other creative projects to keep me busy.
Finally, I found Ecodisc, so I'll be packing my stack off to them soon. If you're in Sydney, Auckland or South Africa you too can recycle your discs.
P.S. If you're in Sydney and have an old computer, printer or other hardware to get rid of, I've got the address for that too. You've got to take it to the depot at Homebush Bay yourself, but at least you know it's not going into landfill.
