Tesco is trialling sales of fresh fruit and vegetables without any additional plastic packaging.
Britain's largest retailer, with headquarters in Welwyn Garden City, Hertfordshire, will run the test at two of its larger Extra stores, in Watford and Swindon.
A total of 45 products will be included in the trial, including apples, onions, mushrooms, peppers, bananas and avocados.
The test follows on from the supermarket giant's commitment to reduce product packaging, ensuring that any remaining plastic has a clear purpose and is recyclable. The company is working to implement a closed loop for its plastic packaging and eliminate difficult-to-recycle materials.
Tesco will be surveying shoppers to find out their reaction to the trial.
Sarah Bradbury, Tesco's director of quality, said: “We want to remove as much plastic as we can from our products, only using what is necessary to protect and preserve our food.
“Whatever happens [with the trial], we're going to keep reducing the amount of packaging we use and ensure everything on our shelves is fully recyclable.”
The trial is similar to one being conducted at competing supermarket chain Aldi. This six-week trial will see plastic packaging removed from five vegetable choices, including cauliflowers and four types of cabbage. Should the scheme be rolled out across the UK, it would save an estimated 110 tonnes of plastic wrap each year.
As with Tesco, Aldi will be monitoring the test to ensure it does not lead to increased food waste.
