A severe drought is currently scorching South Africa and the greater southern Africa region. It is causing havoc across the land, with farmer recording massive losses as crops out in the field wither and animals starving and thirst to death.
Well, an 11th grader Kiara Nirghin from the St. Martin’s School in Jo’burg could have the magic formula (literally) to offer the baking ground some relief (again literally). For her Google Science Fair, Nirghin baked up a low-cost and efficient superabsorbent material that promises great application in fighting the drought menace.
Nirghin’s superabsorbent polymer (SAP) is made from orange peels and avocados skin to make up a low-cost and eco-friendly material. SAPs in themselves are not a new technology, they have been in existence for a while.
What’s the commercial application for SAP?
SAPs are commonly used in area regions, to help farmers mitigate the effects of drought when it doesn’t rain over an extended period. These polymers can absorb liquid water up to 300 times their weight. They are usually mixed as some little gummy balls with the soil or as a sticky slush lay in …read more
