I don't know whether these are new or just new to Tasmania, but I recently bought the BabyLove EcoBots environmentally sensitive disposables (a bit of any oxymoron really). They are made from recycled materials and the manufacturer claims that they are much more readily biodegradable than ordinary ones. And they appear to work just as well as the regular ones. Obviously they still take up heaps of landfill, but nevertheless they are a step in the right direction, so I hope that those who use disposables either occasionally or all the time will consider giving them a try.
