Sainsbury's has removed plastic trays from its "by Sainsbury’s" steak range, replacing them with cardboard instead.
The major UK supermarket chain said the move would help reduce the amount of plastic per tray by 70% and would save 249 tonnes of plastic each year.
Sainsbury's says the trays can also be recycled by rinsing the cardboard before placing it in a kerbside recycling bin.
