Food waste is sometimes impossible to avoid. But wouldn't it make you angry to know that 13,000 slices of fresh bread are rejected every day by one factory supplying M&S, just to avoid putting crusts – and the slices next to them – in its sandwiches?
That's what the food waste expert Tristram Stuart discovered when writing his book, Waste: Uncovering the Global Food Scandal, which reveals just how much shocking waste is produced across the food system.
To help shine a light on such waste, we've teamed up with Tristram to create a Flickr group to showcase your examples of food waste by companies. From small shops and giant supermarkets, greasy spoon cafes and upmarket restaurants to farms and orchards - if they're wasting food, please share your photos there.
To get a sense of the sort of photographs we're looking for, take a look at this gallery of food waste. If you have time to caption and geotag your photos, that would be helpful too.
Hopefully, by highlighting bad practice by companies we'll encourage them to change their behaviour for the better.
Some of the best pictures will feature on Tristram's Liber-ate website, guardian.co.uk and maybe in the print version of the Guardian as well. By posting your pictures in this group you agree to let this happen (though copyright remains with you at all times).
