Saturday, November 22, 2014 - 10:30

Biotoilets are biological toilets, named so because they convert human waste into non toxic, non contaminating water compatible with environmental standards, through application of multi strain bacteria culture, using aerobic forms of bacteria.

Another major advantage of these biotoilets is that they do not need a sewage system to operate. They treat solid waste and convert it to liquid form, which is harmless and does not contaminate groundwater, soil, etc. Learn more about the biotoilet technology here.

One biotoilet costs Rs.25 - 30,000, which includes training on O&M, communication efforts, etc. Multiple biotoilets will cost more. GSF is also working on developing solar powered community bio-toilets.
