Ecological sanitation is a sustainable system for handling which of the following option ?
Answer & explanation
Correct answer: option 2
Ecological sanitation is a sustainable system for handling human
excreta, using dry composting toilets. This is a practical, hygienic, efficient
and cost-effective solution to human waste disposal. The key point to
note here is that with this composting method, human excreta can be
recycled into a resource (as natural fertiliser), which reduces the need for
chemical fertilisers. There are working ‘EcoSan’ toilets in many areas of
Kerala and Sri Lanka.
