A PROCESS FOR THE PRODUCTION OF COMMERCIALLY IMPORTANT PRODUCTS FROM HUMAN URINE Abstract The present disclosure describes a process wherein human urine amended with carbohydrate-rich extract from an agricultural produce wherein the agricultural produce includes tapioca, is processed to produce polyhydroxyalkanoate (PHA), a biopolymer, to recover nutritional elements such as struvite and other mineral such as sodium as sodium bicarbonate, and to entrap ammonia gas released from urine as liquid ammonia. The process includes production of a bioplastic, PHA from human urine by inoculating PHA producing bacterial strain. In another process nutritional elements such as nitrogen and phosphorus can be recovered from the biologically treated urine in the form of struvite. Treating human urine with bacteria enhances the release of ammonia from organic nitrogen. The process includes removal of released ammonia and phosphate from urine in the form of struvite wherein struvite is a slow-release fertilizer. In the process, mineral such as sodium is recovered as sodium bicarbonate from human urine after nutrient recovery by stripping the carbon-dioxide released during bacterial fermentation. The present disclosure also describes a process for entrapping ammonia gas released during the process as liquid ammonia.
