Bio-toilets: Towards an Open Defecation Free Society

Bio-toilets: Towards an Open Defecation Free Society

  • Overview

    Vision / description

    Reach out to places where toilets are rare and facilities are bare; the need is substantial, the problem is acute, and the solution is within reach

    Bio-toilets and the solutions for human waste treatment and water recycling are results of innovation; these will be made accessible in time to come and help in improving the lives of many needy individuals beyond compare.

    Project objectives

    Sanitation facilities in India have been alarmingly poor with an estimated over 600 million people or 100 million households having no access to toilets, particularly in the rural areas. People are forced to defecate in the open, which poses health hazards, raises environmental concerns and leads to water contamination.

    We provide eco-friendly and sustainable solutions for sanitation in rural and urban areas. Our bio-toilets (or bioloos) help treat human waste using bacterial culture, which eliminates the need for its disposal.

    Our toilet system disposes the human waste:
    • in a 100% eco-friendly manner
    • saves energy
    • conserves water
    • produces bio-gas

    Banka BioLoo solutions address the following customer needs/pain points:
    • Meet the need for basic, easy-to-install and hygienic human waste disposal mechanism in areas with no infrastructural facilities currently such as sewerage treatment plants.
    • Address the need for a cheaper and easy-to-operate alternative to the traditional waste disposal system.


    Rural poor, urban slums, peri-urban settlements, schools without sanitation facilities, Indian Railways
    on-site, construction and plantation workers
    Passengers travelling by train
    Poor living near rail tracks
    Women and the aged
    School children

    Current progress

    Our solutions have
     Enabled access to hygienic sanitation to families, schools, members of public, on-site workers, and notably to rail passengers
     Treated human waste and saved/ recycled water; as effluent water from the bio-toilet system is re-used, need for fresh water from municipal sources is reduced
     Railways’s bio-toilets: better hygienic conditions for millions (and increasing) of people living near tracks
     Families and communities, with access to bioloos, don’t defecate in the open, their health has improved as human waste is not littered
     Womenfolk use bioloos and have no fear of security, and have a sense of dignity

    In the past two years, we have deployed, to name a few, bio-toilets in Dhamra, Odisha, with FICCI a trade body; in Rudraram, Andhra Pradesh, with Engineers Without Borders, Student Chapter, for CSR activities of companies such as International Paper, onsite facilities of construction companies such as Shapoorji Pallonji and L&T Metro Rail in Hyderabad. We have upgraded septic tanks of houses, schools and universities to multi-chambered and matriced bio-tanks. With the Indian Railways, we’ve been working for the past 4-5 years on their controlled discharge toilet systems and now the bio-toilets – through supply of tanks, digesters, components and periodic servicing thereof. We have tied up with Shelter Associates (Google Earth Hero), a Pune, Maharashtra, based NGO to provide bioloos in urban slums, and Small Scale Sustainable Infrastructure Development Fund (S3IDF) for provision of services to the underserved.
