Shoppers have earned the equivalent of more than £30,000 by recycling plastic bottles in the first supermarket trial using reverse vending machines to cut down on littering.
The scheme, introduced by the Iceland supermarket chain, rewards people with a voucher worth 10p for every deposit of a plastic bottle bought at the shop.
The trial involved the installation of a machine in four stores – in Wolverhampton, Mold, Fulham and Musselburgh – as well as Iceland’s head office, in Deeside.
New figures show that 311,500 plastic bottles have been recycled since the scheme was rolled out in June.
The supermarket said children were “particularly engaged” with the bottle recycling scheme, and even taught and encouraged their parents to use the machines.
