At the beginning of 2020, it started to use less plastic and more paper in its fruit and veg range, including replacing plastic bands around spring onions with paper versions.

The latest plastic-free initiatives on potatoes and fish could save up to 96 tonnes of plastic a year, with the new fish packaging alternative alone having the potential to save up to 84 tonnes of plastic.
Iceland Managing Director Richard Walker commented on the move. He said: “Removing and reducing plastic from our new potato and fish packaging formats will help our customers have a more sustainable fish and chips dinner while helping us to reduce our plastic footprint.
