The concept of Zero Discharge Green Toilet (Zero D Green Toilet) was selected among 21
finalists out of 133 applicants in national level competition ‘San-Sadhan’ organized jointly by
NITI Ayog, Atal Innovation Mission, Ministry of Jal Shakti, Department of Empowerment of
Persons with Disabilities (DEPwD) and Bill & Melinda Gates foundation. The work was
showcased at Ambedkar bhavan, Delhi to ministry officials, government dignitaries and
subject matter experts from all over the country.
The objective was to provide sustainable, scalable and affordable solutions to make toilets
more accessible for physically challenged people in rural area. We have dedicatedly focused
on all the mentioned objectives along with sanitation as primary aspect while designing Zero
D green toilet.
Key deliverables of the projects are following, along with secondary benefits which vary with
the geographic location and user segment.
Rural community centric features
1. Recreational Space

One working rig of Zero-D Green Toilet with 1 WC and 1 urinal had been setup in IIT Bombay
and was run for 2 years. It was exclusively dedicated to women and children to get the user
feedback. It was independently operating and there was no connection with sewer line,
apart from this there was no byproduct handling needed for the whole 2 years.
