Dammit Maggy, you can't post a question and then answer it yourself six minutes later!! Even if you knew, allow us to wallow in suspense for just a bit!
Anyhow, I like the concept of calling bins Oscars, but seeing how bins around Aus aren't metallic, or even green any more, it seems fairly wrong to name it as I would after the lovable grouch. Recycling bins are black plastic with a yellow lid. The only thing I'm instantly reminded of is Bumblebee Ness, but that's far too random a name for any recycling bin.
As a side note, full of irrelevance: Walking home from work at 4 am sucks. It gets cold at 4 am.
