SOUTH KOREA: Scientist claim that they can convert cigarette filters into a material that could be used by computers, electrical vehicles and wind turbines to store energy.
Sources claim that the discarded cigarette butts are a blight on city streets, but now one group of scientists has come up with a way to reuse them to save the environment. Worldwide, around 5.6 trillion used-cigarettes, or 766,571 tonnes, of used cigarettes are flicked onto pavements each year. That’s equivalent to the weight of 380 London Eyes.
Co-author of the study Professor Jongheop Yi, from Seoul National University, said in a statement that:
“Our study has shown that used-cigarette filters can be transformed into a high-performing carbon-based material using a simple one step process, which simultaneously offers a green solution to meeting the energy demands of society.”
First GM plants to produce omega-3 oil almost ready for harvest: Trial could lead to alternative source of fish oil in the future. Could the moon fuel Earth for 10,000 years? China says mining helium from our satellite may help solve the world’s energy crisis.
The researchers claim the material’s performance is even better that the commercially available carbon, graphene and carbon nanotubes currently used to do the same job.
