All-in-one Affordable Bio-Toilets

Banka BioLoo is a women-led social enterprise in India providing environmentally-friendly and sustainable solutions for sanitation in rural, urban and peri-urban areas. Their bio-digester uses anaerobic bacteria to convert the organic waste into methane and CO2. The anaerobic process kills the pathogens responsible for water-borne diseases. The bio-digesters are designed as low-cost underground tanks that ensure anaerobic conditions at the required temperature for the bacteria.

I have taken a lot of initiative to popularise this technology. It’s a huge opportunity for India and for us as a business.

The Banka BioLoo meets the need for basic, easy-to-install and hygienic human waste disposal in areas with minimal infrastructural facilities and no existing sewage systems. The company claims that their system is maintenance-free and low-cost, and that it does not require any input energy, plumbing connections to sewage infrastructure or sludge disposal.

Why you should care

In India, up to 65% of the rural population and nearly half the total population defecate in the open – more than in any other country. This poses significant health risks and is a source of waterborne diseases. In addition, poor sanitation infrastructure disproportionately affects women through increased risks of sexual assault. Addressing poor access to adequate sanitation globally has been challenging, but this solution shows how low-cost innovation can help solve the crisis.
