School children in Gloucestershire are taking part in a challenge to reduce the amount of food waste produced at lunch times.
The idea is part of the council's "Wipe Out Waste Week" where pupils who take packed lunches are asked to think carefully about what they include.
Pupils who have school meals will be asked to consider their portion sizes to help cut down on leftover waste.
Thirty schools have signed up to the project, which begins on 22 November.
Councillor Stan Waddington, from Gloucestershire County Council, said: "We've found that getting children to understand the waste pressures and the need to reduce, reuse and recycle is a great catalyst to encouraging their parents to do their bit too and that is ultimately our aim."
