Green Airline... recycling waste?
Don't make me laugh.
Air EnZed have been doing that for a decade now, showing up other operators, recycling light weight re-usable polymer utensils, plates, newspapers etc... back in 2009 they made 5 Mill profit from it for their whole network! Many other airlines have followed in various ways since the 2000's
QF - Great "step forward" but way overdue and pretty much seems you've been "shamed" into doing it.
No point commenting on the other points above as it's comprehensively covered in many of the replies.
Happy Landings
