Researchers at the University of Edinburgh have discovered a way to make use of ‘fatbergs‘ – the massive blockage in sewers, formed when non-biodegradable waste (like wet wipes) mixes with fats, oils, and grease.
The biochemists have been feeding modified bacteria on sterilised fatbergs, which then turn the waste into a sweet smelling pine fragrance compound.
Biotechnology professor Stephen Wallace told STV news, “The molecule we’re making is a tree pine fragrance – it’s a really high-value molecule used across the cosmetics industry. What the project shows is it’s possible to feed these bacteria in a way that makes products useful to everyday society. The fact you can make it from horrible sewer waste sort of still blows my mind – but it’s scientifically possible.”
Prof Wallace adds, “The costs associated with disposing of fatbergs – removing, throwing, bringing them in – are significant. We’re showing the cost can be offset and even increased by producing something from fatbergs that is useful and valuable.”
Would you wear a perfume made from recycled sewer waste if it smelled amazing, or does the idea still make you hesitate?
