Sharada’s research is focused on recovery of nutrients, primarily Phosphorous, from human waste, particularly septage, and their reuse in Indian agriculture. His work focuses on understanding policies and regulations that encourage businesses to facilitate reuse of septage as fertilizer. He is interested in knowing why some farmers do not use faecal sludge irrespective of its high nutrient value. He is exploring frameworks to quantify the microbial risks involved in collection and reuse of septage, and estimate potential Phosphorous and Nitrogen that can be augmented by reuse. His research also encompasses social and environmental justice issues arising out of caste based discrimination in India. He uses photography to communicate his research.
