Eco-friendly Water Retention Natural Polymer
Project Description :

In india 266 districts, in 11 states declared drought affected. the average food grain production between 2010-2011 and 2014-2015 is 255.59 million tones, while in 2015-2016, it is estimated to be at 253.16 million tones. more than 70% districts drought affected in 8 states. superabsorbent polymers (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. during more research in the topic, i found that natural occurring polymers exist in most citrus fruits. orange peels contain over 64% of polysaccharide making it a candidate for biodegradable polymer. however, the polymer has to be cross-linked usually requiring chemicals such as sulphur and hydrochloric acid. i have explored an organic cross-linking method using uv light and heat. emulsion polymerization was then conducted by using natural oil found in avocado peels and adding it to boiled orange peels. the product is then left in the sun, utilizing photo polymerization. the product should be able to retain large amounts of water and combat the effects of drought on crops by retaining soil moisture, whilst still recycling waste products of the juice manufacturing industry.
