A water firm has announced plans to step up the fight against fatbergs.
Scottish Water and Zero Waste Scotland are working in partnership on a new project to reduce the number of blockages appearing in sewer systems.
The pilot scheme will involve educating businesses and local people in the town of St Andrews on what they should - and should not - be pouring in sinks and flushing down toilets.
Iain Clunie, Food and Drink Programme Manager at Zero Waste Scotland, said the project was "seeking to change behaviour".
Speaking to Julia Hartley-Brewer on the breakfast show, Mr Clunie said: "We have people disposing of fats, oils and grease down drains, sinks and all sorts of other things doing down toilets, we'd prefer didn't.
"The challenge we're looking at is influencing behaviour change."
If successful, the project could be rolled out to other parts of the country.
"I think it's an issue throughout the UK, and Scotland are looking to take the lead with this project," Mr Clunie added.
Fatbergs are blockages which form in sewer systems and are made up of a range non-biodegradable matter, including wet wipes, oil, grease, fat and nappies.
A fatberg weighing 130 tonnes (the equivalent of 11 double-decker buses) was discovered in a London sewer in 2017. A section of it was later put on display in the Museum of London.
