An interesting scenario developing chez sunny-dave.
I know that I must not contaminate my assorted (three at the last count) recycling bins with 'incorrect' contents - I'm punctilious about sorting/separating correctly.
But I've always assumed that it is entirely up to me to decide what I put in my 'black bin' - for residual rubbish.
I've just a a stroppy "stop it or we'll stop collecting" sticker on said black bin, saying that I had incorrectly put recyclable items in there and (although they've taken them this time) next time it will be left for me to sort out properly.
The stuff in question was a big pile of (moderately) sensitive paperwork - nothing that would actually pose a threat to my identity/security, but equally not things I'd want being picked over by the recycling sorters.
In my previous house I'd just have bunged the lot into the woodburner - but that's not an option here.
My black bin goes straight into a waste-to-power plant & so that seemed a good enough solution.
I know what I'll do next time (double bag the offending items in opaque bin bags) - but I'm a bit huffy about the warning.
I suspect that councils who adopt the attitude that dave has come across are not simply being awkward; they are bound by rules (probably from the EU) that dictate to them what should be tipped on landfill and what should be recycled. If they don't toe the line, they get a fine slapped on them.
