"Too Good To Waste" which has been organised by the County Council, will see "Take Me Home" boxes given to 100 restaurants to offer to diners, so they can go home with the food they can't eat.

The campaign aims to make it socially acceptable as well as a positive experience for diners.
County Councillor David Nimmo Smith said, "Food waste is a serious problem. For every meal eaten in a UK restaurant, almost half a kilo of food is wasted.
