Households across Bristol are being given scales and even a wormery to help them lower the amount of food and household waste they throw away.
Bristol Waste have issued the zero waste challenge to 50 households in the city.
Participants will give their decomposing food waste to a family of worms inside a wormery instead of throwing it away.
They will have to weigh their waste for 365 days and record the levels in an online form.
Bristol Waste are responsible for recycling and waste collection in the city and will offer free workshops and support throughout the year to those involved.
It is hoped that the zero waste challenge will inspire others to think about what they are throwing away.
