 The journey

Uttam Banerjee grew up in small town called Bokaro in Jharkhand. There was a beautiful river near by where he along with friends used to bath and do their day to day activities including defecation as they did not have any toilets at home. As a child he had beautiful memories of visiting that place and while growing up he never realized that it may be a way of living for all of us but a big problem for the women in our houses until he got married.

In Uttam’s words, “It was 2010 just after my marriage when one fine day I asked my wife to visit my village with me. I actually wanted to show her how beautiful the place was. The very next question she asked was “do you have a toilet in the house?”. She straight away refused to travel with me when she heard my answer. I realized that for me it may be ok and an enjoyable experience to do away with the nature’s call in the open but it is a matter of dignity and pride for the other gender. I traveled alone to my village after my marriage to cherish my beautiful childhood memories but all went into vain when I saw that the river is no more beautiful and it had eventually turned into a big drain. I was very disappointed after that particular incident and felt there is more meaningful work that I should do as an educated human being.“ One thing led to another and Uttam decided to quit his corporate job and start something meaningful to make people’s lives better. Looking back and connecting the dots, he felt water scarcity, soil and water pollution, health & hygiene and sanitation are all interlinked and needs a strong focus.

Zerodor is an attempt to recover urine and feces in pure form so that it does not pollute the soil and water and can be converted into useful fertilizer. The only way you can do this is to avoid flushing the pans. The initial iterations revolved around both urine and feces which evolved into a waterless urinal for men and women.
