Pupils from Ysgol Gymraeg Cwmbrân have helped reduce school canteen food waste by almost 36 per cent.
The school has been crowned this year's Waste Warrior champion after helping to reduce food waste as part of a borough-wide competition.
As part of the challenge, members of the school's Eco Committee reviewed menus, measured lunchtime food waste and led a whole-school campaign encouraging pupils and staff to reduce waste.
They also worked closely with the kitchen team to identify which foods were being wasted most often and explored ways to reduce it.
At the end of the four-week monitoring period, their efforts resulted in a 35.98 per cent reduction in food waste.
Judges were impressed by the pupils' enthusiasm, teamwork and innovative approach to tackling food waste.
Cllr Sue Morgan, Executive Member for Sustainability and Waste, said: "Congratulations to Ysgol Gymraeg Cwmbrân on becoming this year's Waste Warrior champions.
"The school is no stranger to success being the winners of the competition a few years ago. Their continued commitment to reducing food waste has been outstanding and highlights the important role young people can play in protecting the environment.
"By encouraging their classmates to think differently about the food they choose and eat, these pupils have helped create lasting habits that are good for both their health and the planet."
Catrin Evans, Head Teacher at Ysgol Gymraeg Cwmbrân, said: "We are incredibly proud of the Eco Committee and everything they have achieved.
"They embraced the challenge with enthusiasm and showed great leadership in promoting positive changes throughout the school.
"Their efforts have helped raise awareness of food waste and inspired other pupils to play their part."
As part of their prize, pupils will take part in a full-day healthy cooking session funded through the Torfaen Food4Growth partnership.
The Waste Warriors competition was launched by the council's catering team in 2023 as part of its commitment to making school meals more sustainable. Last month, the team received national recognition for its climate-friendly approach to school meals.
The competition supports wider efforts to reduce food waste, encourage healthy eating and help schools play their part in tackling climate change.
As part of its ongoing work to develop school menus and expand plant-based options, the council's catering team is also working with The Queen's Inn, Cwmbran, to explore new vegan and vegetarian dishes for pupils.
