The Innovation

Kiara was sixteen years old at the time of her win at the Google Science Fair. She is known as the sole founder of her project titled: "No More Thirsty Crops." [6] [7] In response to one of South Africa's worst droughts in 45 years, with the lowest ever rainfall since 1904 and in 2015, the country only receiving 66% of the annual average rainfall, did Kiara start her research. SAPs absorb and carry about 300 times its weight in liquid relative to their own mass. When a SAP is cross-linked with polymerization, the product is water retaining hydrogels that act as a reservoir of collected water in soil. However, these SAPs are not biodegradable, costly and full of acrylic acid, sodium hydroxide and other chemicals. Kiara developed a unique super-absorbent polymer that holds hundreds of times its weight in water when stored in soil. It is biodegradable, inexpensive and free of harmful chemicals, unlike the manmade materials currently used. The polymer, made entirely from waste products, improves the environment, increases the chance for plants to sustain growth by 84% during a drought and can increase food security by 73% in disaster-struck areas. [8]

Activities

Kiara has often spoken out on the importance of diversifying the STEM (Science Technology, Engineering and Mathematics) fields to include young girls. [9] As a speaker at TEDx [10] and Forbes Africa [11] she has identified herself as an influential speaker. In September 2017, Kiara was a speaker at the Lead S.A Change Makers Conference. [12] In 2018, Kiara was nominated as a Regional Finalist of the 2018 United Nation’s Young Champions of the Earth. [13]

Biodegradation Decomposition by living organisms

Biodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi.

Bioplastic

Bioplastics are plastic materials produced from renewable biomass sources, such as vegetable fats and oils, corn starch, straw, woodchips, sawdust, recycled food waste, etc. Bioplastic can be made from agricultural by-products and also from used plastics by using microorganisms. Bioplastics are usually derived from sugar derivatives, including starch, cellulose, and lactic acid. Common plastics, such as fossil-fuel plastics are derived from petroleum or natural gas.

Biodegradable plastic Plastics that can be decomposed by the action of living organisms

Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass. Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all three.
