It's never a pretty sight cleaning up after school lunches, but one Italian catering boss plans to get around this problem by creating a range of edible plates for schools that never need washing.
Tiziano Vicentini made the plates out of bread dough so that they would be strong enough to hold someone's lunch but tasty enough to eat afterwards. He came up with the idea because he had become sick of seeing schools waste money on plastic plates and dishes or expensive dishwashers.
"These dishes cost a few pennies each and are either eaten or can go into the recycling bins for animal food," he explained. Let's just hope pupils don't enjoy the plates so much that they ignore what's on them.
