India is presently experiencing one of the worst drought in 45 years,with the lowest ever rainfall since 1904. in 2015 india received only an average of 403 mm which is merely 66% of the annual average rainfall. the matter has to be urgently addressed,with food source under severe strain and still household food security being a major concern. however,a clear solution would be superabsorbent polymer (saps). saps absorb and carry about 300 times its weight in liquid relative to their own mass. when a saps is cross-liked with polymerization the product is water retaining hydrogels that act as a reservoir of a 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 polymer exist in most citrus fruits. orange peels contain over 64% of polysaccharides 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 effect of drought on crops by retaining soil moisture whilst still recycling waste product of the juice manufacturing industry.
