In the end my neighbour took mine, I'll see if she wants any more. It's always a shame to see stuff going to landfill.I too have several plastic bags full of this type of white chipping. I was going to take it to the tip (which would cost quite a bit I think) so VERY glad if you would like to take it. I am at 29 Blenheim Ave.
