Sanitation facilities in India are alarming with over 600 million people (half of India's population) having no access to toilets. Bio-toilets treat the human waste at source – obviating the need to carry/transport the fecal matter, no spoiling of environment or groundwater, and don't need any energy, no heavy infrastructure required – easing the burden on government bodies. On the contrary, there are other benefits of the bioloo. The system leaves pathogen-free water as effluent that can be re-used. For large bio-tanks, methane can be collected and used. These can be installed anywhere, without specification of land type, terrain, distance, etc. We see bio-toilets as a true panacea to many of India's sanitation woes.

Banka BioLoo Pvt Ltd, a firm committed to environmental betterment and social uplift, is supporting to eradicate the malaise of open defecation. By providing eco-friendly bio-toilets (or bioloos), the enterprise is helping meet the Millennium Development Goals (MDG-7) and actively supporting the government's vision of an open defecation free society.


Banka's solutions address the following needs/pain points of the end-user:
• Meet the need for basic, easy-to-install and hygienic human waste disposal mechanism in areas with no infrastructural facilities
• Address the need for a cheaper and easy-to-operate alternative to the traditional waste disposal system.

The bio-toilet system consists of an easy to install super-structure, a multi-chambered matriced bio-tank that holds the bacterial culture and allows the treatment of the human waste. The system doesn't need any external energy for treatment, rather emits pathogen-free effluent water that is good for gardening and similar purposes; and bio-gas that could be used for cooking or heating (in case of large institutions). The system meets all regulatory and environmentally compliances and enhances the socio-environmental fabric of India. Moreover, the bio-digester technology was initially developed by Defence Research and Development Organisation (DRDO) for the defence personnel. The enterprise is pioneering this, in an integrated approach, and taking this effective and innovative sanitation solution to the civil population with varying applications.

Impact and Results

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
