Researchers from the University of Sydney have done just that, and have developed a method that uses durian and jackfruit waste to create energy stores for rapid electricity charging.
How does it work
The fruits’ waste portions (biomass) of durian and jackfruit purchased from a market into super-capacitors that can be used to store electricity efficiently, said Researchers.
“Using a non-toxic and non-hazardous green engineering method that used heating in water and freeze drying of the fruit’s biomass, the durian and jackfruit were transformed into stable carbon aerogels—an extremely light and porous synthetic material used for a range of applications.
“Carbon aerogels make great super-capacitors because they are highly porous. We then used the fruit-derived aerogels to make electrodes which we tested for their energy storage properties, which we found to be exceptional.”
Why durian and jackfruit
Durian waste was selected based on the excellent template nature provides for making porous aerogels.
The durian and jack-fruit super-capacitors perform much better than the materials currently in use and are comparable, if not better, than the expensive and exotic graphene-based materials.
Durian waste, as a zero-cost substance that the community wants to get rid of urgently due to its repulsive, nauseous smell, is a sustainable source that can transform the waste into a product.
