Except that many councils reject recycling bins with the lids in,
because they are made of a different type of plastic.


If we're talking milk bottles here, I haven't seen one this
century with the cap made of a different material - only the
colour is different.

2 litre fizzy water bottles in particular and some other fizzy
drink/cordial bottles.

I hav often thought that some sort of shredder would make sense for
plastic bottles.


Might make it difficult for sorting at the recycling site,
though.

How do they sort? I know it is automated (that's why black ready meal
trays can't easily be recycled, as the systems can't see them). I assume
that they use different frequencies of "light" and the different
plastics show up differently. Separate peices rather than whole bottles
should stil be sortable. I am not talking about cross-cut shredding into
tiny pieces. Pieces a couple of inches square would probably be small
enough to pack together well and large enough to be sorted.
