As far as I can make out there's not much that can't be packaged in something widely recyclable.
Surely if it was law (or something) then the cost (I guess that's the problem) would come down massively if everyone had to use it.
I find recycling a pita because of having to 'sort' it - still do it but it's such a faff.
Not an exciting thread I know, but it's been bugging me for years ....
