Experts say classrooms could play a pivotal role in shaping lifelong environmental habits while cutting thousands of tonnes of waste

Schools across the UK are being encouraged to take a leading role in tackling climate change, as new insights reveal the scale of waste generated within the education sector.

Marking Global Recycling Day on 18 March, education experts are calling attention to the unique position schools hold, not only as centres of learning, but as influential environments where sustainable habits can be formed early.

While classrooms are often seen as places of innovation, they are also significant sources of waste.

However, much of this could be reduced or diverted from landfill through relatively simple changes.

A long-term opportunity for change

Dr Richard Anderson, Learning Experience Director at High Speed Training, emphasised the broader impact schools can have beyond immediate environmental gains.

“We urge schools to look beyond the immediate environmental benefits and consider the long-term impact.

“By integrating recycling into the school day, educators help children form lifelong habits that turn them into conscientious, environmentally aware adults.

“The education sector has a profound opportunity to lead by example.

“When schools embrace waste reduction, they don’t just lower their carbon footprint; they improve their reputation with parents and can even see significant savings in their over-stretched budgets”

The biggest sources of school waste

Four key areas have been identified as the main contributors to waste in schools, highlighting where action could have the greatest effect.

Paper remains the largest source, with primary pupils producing around 45kg each year, compared to 22kg per secondary student.

Food waste is another major issue. Primary schools in England generate more than 55,000 tonnes annually, while secondary schools add nearly 25,000 tonnes, bringing the total to over 80,000 tonnes every year.

Plastic waste, from items such as milk carton straws and sandwich packaging, continues to pose a challenge. Simple swaps, including reusable bottles and bulk dispensers in canteens, could significantly cut down on single-use plastics.

Electronic waste also requires careful handling. Under current regulations, items such as printers and monitors must be disposed of responsibly, with some materials, like ink cartridges, taking up to 1,000 years to decompose in a landfill.

Confidence gap among teachers

Despite growing awareness among young people, a gap remains between students’ interest in environmental issues and teachers’ confidence in delivering the subject.

Research shows that 68% of students want to learn more about the environment, yet 75% of teachers feel they have not received sufficient training to teach climate change effectively.

Practical steps for schools

To address this, experts suggest a number of practical measures schools can adopt.

Encouraging student involvement, such as designing recycling posters and labels, can help boost engagement.

Conducting waste audits allows schools to better understand what is being thrown away before introducing initiatives like composting.

Meanwhile, improved staff training can ensure teachers feel confident leading discussions on sustainability.

“A mindset of sustainability”

Dr Anderson said the annual awareness day should serve as a catalyst for lasting change within school communities.

“Global Recycling Day serves as a vital reminder that our resources are finite, but our capacity for change is not. Schools are the heart of our communities.

“By empowering teachers and students with the right knowledge today, we aren’t just managing waste; we are cultivating a mindset of sustainability that pupils will carry with them for the rest of their lives.”
