Not sure exactly when they changed but I noticed new plastic trolleys in Dickson today. I have my doubts that entirely replacing a fleet of salvageable metal trolleys with plastic ones (even if recycled plastics) is actually "pushing for a greener future".
These are good points. Also, 74 milk cartons doesn't seem like enough for that amount of plastic. It's like saying a hot chocolate is made with real chocolate. That's great and all, but that's only 10% of the drink.
