I think some of the 'fully biodegradable' disposable nappies are just another advertising gimmick. If disposed of in the same way as most household rubbish, the majority if not all are still unable to break down.

My brother has experimented with a few and tried to break them down in compost and using various methods. Nothing, nada they still exist 12 months later.

If anyone has info to the contrary, i'd be happy to read it, but so far my interest in the biodegradable nappy has been dissappointing.

Thanks Jellybean for starting this thread, and bumping it til it generated some interest!
