Environmental Issues of Ecosan Toilets
About 150 liters of wastewater at an average is generated by an Indian individual daily, and a large amount of it is generated from toilets. Ecological sanitation (EcoSan) is a sustainable system for handling human excreta by using dry composting toilets.
EcoSan toilets not only reduce wastewater generation but also generate the natural fertilizer from recycled human excreta, which forms an excellent substitute for chemical fertilizers. This method is based on the principle of recovery and recycling of nutrients from excreta to create a valuable supply for agriculture.
‘EcoSan’ toilets are being used in several parts of India and Sri Lanka.
Eco-San is a specially formulated food contact surface sanitizer and destainer for use in low-temperature warewashing machines that rinses clear. Eco-San leaves dishes, flatware and glassware both sparkling and hygienically clean, as it combats a broad spectrum of organisms.
The EcoSan toilet is a closed system that does not need water, so is an alternative to leach pit toilets in places where water is scarce or where the water table is high and the risk of groundwater contamination is increased. When the pit of an EcoSan toilet fills up it is closed and sealed.
It is being used in Gulbarga, Karnataka. A self flushing e-toilet (using concept of pay & use toilet scheme) are toilets that are designed in such a way that it flushes itself on entry and exit with a drop of coin. They are
prevalent in Delhi, Kerala and Mumbai for footpath and slum dwellers.
Wherever the Need, an NGO in the UK build ecosan facilities (UDDTs) in various parts of the developing world. They predominantly work in Tamil Nadu (India), where the Tamil Nadu State Government
provides subsidies for their work.
