 Bio-toilet by ‘Green Solution Foundation’
GSF (Green Solution Foundation) has created a bio-toilet solution for hygienic sanitation in villages and in
slums in cities that lack sewage systems. Users or donors fund these bio-toilets while GSF provides training
on toilet use and servicing involving the local population, thus creating employment and entrepreneurship
opportunities. The Bio-digester tank forms the basis for this eco-friendly toilet. Using aerobic bacteria, this tank
converts human waste into environment standard compatible water which is used for fl ushing or even for
irrigation.

 Water conservation due to less flushing
 Efficient sewage system
 Decrease in soil and water contamination
 Decrease in diseases due to hygienic sanitation.
