Remember that article we ran mid-August; about the fruit girl who developed a superabsorbent polymer (SAP) out of orange peels and avocado skins? Well, that girl, 16-year-old Kiara Nirghin from Johannesburg, South Africa, bagged the Google Science Fair 2016 Grand Prize this past Tuesday.
Nirghin project summited to the fair won as it seeks to mitigate the adverse effects of global warming in Southern Africa. Her home country, South Africa like many other countries on the continent has been hit by one of the worst droughts in history. The country recorded the lowest rainfall ever since 1904. Nirghin’s project wants to retain more moisture inside the soil from the less frequent rainfall that falls on the land.
Out of orange peels and avocado skins, she came up with a compound that holds hundred times of water in weight and keeps the soil moist for longer. The best part of her product is that it can be readily made out of kitchen waste and biodegradable materials. Meaning farmers will not be adding more toxic chemicals into their farms, which are also non-biodegradable. Not forgetting, the alternative she …read more
