allan: And for a while in Wellington we had the "no meat trays even if they are a 1" rule. Once they'd been rinsed and left on the bench, how did you remember whether they held meat or donuts? 

 

Maybe it's a case of asking the meat tray whether it self-identifies as a donut tray?

 

Seriously though, is there anything other than meat that's held in those mesh-base trays? 

Possibly not, but then again, not all meat was in those sort of trays. Moot point now anyway, as uniform recycling rules across the country.
