Just been fueling up at Z and the car ahead was getting gas & clearing their car of rubbish.  While the gas was being pumped by the guy, his partner & a young child were carefully putting rubbish into the three bins at the pump.  These were 'Landfill', 'Glass', and 'Plastic'.   I would love to know what actually happens to the clear plastic bags in these bins.  As these petrol stations barely have enough staff to pump gas, make coffees, restock shelves and drink cabinets, watch for drive-offs, etc I think it highly unlikely that these plastic bags actually finish up being sorted on site.  Back in the day Shell stations made no pretense of recycling there was just a rubbish bin at each pump and all the rubbish went into a skip behind the petrol station.  I think that it's highly possible that is what happens now at the Z stations!  I'm not picking on 'Z' I bet much the same happens at their competitors.

Christchurch City Council is just as bad if not worse.   If you go to either Jellie Park or Pioneer Stadium you'll see big green wheelie bins with yellow or red lids and it's a very lame attempt at 'green wash'.   All the black rubbish bags from those big wheelie bins go in the same orange waste management skip.  If you don't believe me  go to Jellie Park on a summer afternoon & watch what happens!   The process is in full view!   Cardboard is actually re-cycled properly with dedicated steel cages.

Although I no way of proving it I bet the same happens at Christchurch airport.  They have a two bin system there as well.
