How much cash do you end up wasting on food because you can't remember what you already have (or don't have) sitting in the fridge at home?
Sainsbury's thinks that it could be quite a lot and might just be one of the reasons for families wasting on average £235 each year – that'll be £1.5bn across Britain amounting to 4.2m tonnes of wasted food.
To help solve this problem, the supermarket is testing out smart fridges with specially chosen families. They'll get a shiny new Bosch fridge that includes a camera which can send images to a smartphone or tablet so that when they're out and about, they can check exactly what they need, rather than doing that "just in case" purchase.
"With our focus on finding innovative solutions we have teamed up with Bosch to trial their unique camera fridge which will give shoppers an instant view of the contents of their fridge whilst shopping," said Sainsbury's head of sustainability Paul Crewe.
"Our customers tell us that despite best intentions, they often find it difficult to remember what is in their fridge, which can lead to them over-buying."
The six month test with 20 families in Derbyshire and if it proves a success, could be rolled out to more people, a supermarket spokesperson told HuffPost.
Swadlincote in the south of the county is home to a major Sainsbury's trial to get an entire town to cut down on its food waste by half this year.
