Tesco tracked 25 best-selling products and combined information with data from the Waste and Resources Action Programme (Wrap) to give an overall food waste "footprint" for each item.
The data shows that in the first six months of this year, 28,500 tonnes of food waste were generated in Tesco's stores and distribution centres.

We've all got a responsibility to tackle food waste and there is no quick-fix single solution. Little changes can make a big difference, like storing fruit and vegetables in the right way.
Families are wasting an estimated £700 a year and we want to help them keep that money in their pockets, rather than throwing it in the bin.
We're playing our part too and making changes to our processes and in store.
