Indian Researchers Selected to Develop Next Generation Toilets
Indian and global researchers gather at “Reinvent the Toilet Fair: India” to discuss how to bring safe sanitation to the 2.5 billion people who lack access.
New Delhi, March 22, 2014—Six Indian innovators were selected today to contribute to the development of sanitation solutions as part of the Reinvent the Toilet Challenge: India. From a pool of 108 applications, these projects were chosen following an extensive,
rigorous selection process by a committee of experts.
The “Reinvent the Toilet Challenge: India” is a collaborative effort of the Department of Biotechnology (DBT), Ministry of Science and Technology, Government of India; Biotechnology Industry Research Assistance Council (BIRAC), A Government of India Enterprise; and the Bill & Melinda
Gates Foundation to fund Indian researchers to develop innovative, safe and affordable sanitation technologies. This program is an India-specific program modeled on the Gates Foundation’s global Reinvent the Toilet Challenge. The DBT and the Gates Foundation invested a combined US$2
million, equally split, to support Indian investigators to drive research, development, and production of “next-generation toilets.”
The grants were announced today by Prof. K. Vijay Raghavan, Secretary DBT & Chairman, BIRAC at the “Reinvent the Toilet Fair: India”, an event held in New Delhi that showcased innovative products and approaches that aim to bring safe, affordable and sustainable
sanitation to those who need it most.
Co-hosted by the DBT and the Gates Foundation, the fair included more than 45 exhibitors representing 15 nations and featured projects to stimulate discussion among a diverse group of stakeholders working to improve global sanitation. These include efforts to create toilets that are not
connected to water, sewer or electricity; improve the collection, treatment and disposal of human waste; address behavior change; and raise awareness of this critical issue for governments, stakeholders and local communities.
The fair was an opportunity to recognize India’s leadership and commitment to improving child health and fostering innovative solutions to persistent development challenges. It also was an opportunity to hasten manufacturing opportunities in India of existing sanitation products.
“Effective and comprehensive sanitation seems an impossible dream for India,” said Professor K. Vijay Raghavan. “Yet today we see a congruence of new and applicable science and technology, its affordability, and sustainable implementation. This congruence is a great opportunity which
we cannot afford to let slip. By implementing effective solutions in each kind of social context, big problems can be dealt with in small units and be catalysts for scaling up. By working together to hit big barriers at the right place and the right way, they can crumble and the impossible can
Also announced today at the fair, the Department of Science and Technology for the Republic of South Africa is committing ZAR 30 million to field test technologies developed as part of the Gates Foundation’s global Reinvent the Toilet Challenge in rural communities and schools. The
foundation is contributing US $1 million to support this testing.
“By applying creative thinking and new approaches to sanitation challenges, we can improve people’s lives. And we have no doubt that these new partnerships with India and South Africa will help us achieve this,” said Brian Arbogast, director of the Water, Sanitation and Hygiene team at
the Bill & Melinda Gates Foundation. “We believe that with governmental leadership, new business models and innovation, we can dramatically increase the progress made in tackling this global sanitation crisis.”
The fair was an opportunity for the16 global Reinvent the Toilet Challenge (RTTC) grantees, funded by the Gates Foundation, to exhibit progress and demonstrate
“We are impressed by the progress the Reinvent the Toilet Challenge grantees have made,” said Arbogast. “Our goal is to fund the development of complete solutions – solutions that are affordable, that work, and that people want to use. Our grantees have been working on aggressive
timelines and we are very encouraged by the progress these grantees have made since the first fair in August 2012."
The details of the grant recipients for the “Reinvent the Toilet Challenge: India” are as follows:
Eram Scientific Solutions Pvt. Ltd., Kerela in collaboration with University of South Florida:
A field trial grant to test off-grid, self-sustained, modular, electronic toilet for houses and communities with solar energy for Indian weather, integrated with mixed waste processing unit. The project will couple a modern, public toilet with an advanced onsite, biological treatment system. It
will be housed in a standalone unit that will be initially field tested in a suburban slum.
Amrita School of Biotechnology, Kerela: A proof of concept grants to use viral agents to target and kill pathogens and odour-producing bacteria in fecal waste and also develop for a way to integrate this into waste treatment systems. This is a proof of concept grant.
Pradin Technologies Pvt. Ltd., Bangalore:
The project will test the concept of using ultra-sound to reduce water use in a toilet. It will also test the ability to enhance the settling of fecal particles in a storage tank using ultra-sound. This is a proof of concept grant.
Indian Institute of Technology Roorkee in collaboration with Fresh rooms Life Sciences:
The project will develop a single household container that will cultivate Black Soldier Fly larvae, using human faeces, which can be processed into valuable products. The project will also demonstrate the market potential for these products. This is a proof of concept grant.
Institute of Chemical Technology, Mumbai:
The project will evaluate the concept of using fine sand-like material and an air blower to create a water-free toilet interface that is free from odour and flies.
BITS PILANI K. K. Birla Goa Campus in collaboration with Ghent University and Sustainable Biosolutions LLP:
The project will demonstrate a novel septic tank design that integrates electrochemistry to reduce organic pollutants and improve the quality of effluent discharged. The system will be demonstrated at a single household and society/gated community. This is a proof of concept grant.
The Reinvent the Toilet Fair: India hosted approximately 700 attendees—exhibiting teams represented 15 nations and general participants represented 42 nations. For a full list of exhibitors visit,
