The Co-op is launching a 6p shopping bag which can be thrown on a compost heap when it wears out.
Bosses say the bag – made of polyester and cornstarch – is the UK’s ‘first fully-accredited home compostable carrier’.
They say the bag’s popularity will be tested at selected stores in East Anglia before it is offered nationwide.
Plastic bag curbs
The Co-op says stores taking part in the trial will not offer free plastic bags.
A spokeswoman said: ‘To get the most use out of compostable bags, it is best to use them for shopping a few times, then line a kitchen compost caddy or use them to catch vegetable peelings before putting them into a garden compost bin. They are not suitable for recycling.’
The Co-op says it will also offer degradable carriers – at a cost of 1p and 2p – which break down within three years and can be recycled in new store bins as part of the trial.
