Rural areas of Cambodia have no safe waste management strategies for household latrine waste. Household application of lime (calcium hydroxide, Ca(OH)2) would enable households to treat waste easily on-site and significantly reduce the risk of latrine sludge causing negative impacts on human health and the environment, whilst transforming latrines into incubators of a valuable agricultural additive. Initial investigative work – including human centered design research, supply chain analysis and bench scale laboratory tests have demonstrated that lime treatment of sludge has potential to provide a sustainable and effective solution to closing the sanitation loop in rural Cambodia, with promising application for urban environments as well.
