Environmental campaigners have criticised Manchester City for encouraging supporters to dump used plastic bottles in recycling bins - in return for air miles.
The club announced the scheme on its website on March 4 ahead of the Manchester derby, informing fans that 'recycling pods' would be installed at the main entrances to the ground 'in partnership with Etihad Aiways', its main sponsor.
Supporters were urged to use the pods and then scan the adjacent QR code to earn 'Etihad Guest Miles and help make a difference to the planet'.
