I was having one of those conversations yesterday, where you start off on one topic and before you know it you're talking about something else and you don't know how you got there!
Anyway, it turns out that in some areas councils are selling all the dust that gets swept up off the streets to developing countries (Mexico was mentioned) for recycling.
I had always imagined that it all went to landfill...actually I hadn't given it a moments thought before, but if I had I would have said landfill
.
So my question to you all is: how is this viable? and why would anyone want our dust anyway?
If no-one gets it, I'll post the answer tomorrow.
