Application
Description Kiara Nirghin, a 16-year-old South African, developed a super absorbent polymer using orange peel and avocado skins to combat drought. The polymer can store hundreds of times its weight in water, providing a low-cost solution for farmers to maintain crops during water shortages. The material is sustainable, using recycled waste products, and is biodegradable. Kiara's innovation won the Google Science Fair’s Community Impact Award for the Middle East and Africa.
Pathway Description: Kiara Nirghin extracted polysaccharides from orange peel and used the oil from avocado skins. She combined these materials and left the mixture in the sun, where they reacted to form a super absorbent polymer (SAP). This polymer can store large amounts of water, making it ideal for agricultural use. The process utilizes waste products, making it an eco-friendly solution for drought management.
