Reinvent the Toilet Challenge & Expo
On November 6-8, the Bill & Melinda Gates Foundation joined global innovators, development banks, corporate partners, sanitation utilities and governments to host the first Reinvented Toilet Expo in Beijing.
The expo featured product announcements and funding commitments aimed at accelerating the adoption of innovative, pro-poor sanitation technologies, in developing regions around the world. Each are first-in-class products designed to kill pathogens that make people sick and transform human waste into valuable resources at a low cost to users—all without connections to water supply or sewer systems.
These technologies are at the forefront of a growing movement to rapidly improve safe sanitation for the world’s poorest, while creating new, profitable sanitation markets that sustain progress toward global water and sanitation goals outlined in the United Nation’s Sustainable Development Goals (SDG 6).
To learn more about the product and technologies featured at the expo, please see the expo Exhibit Guide. You can also visit www.stepsforsanitation.org/rte for more information about products and research.
About the Reinvent the Toilet Challenge
In 2011, the Water, Sanitation & Hygiene program initiated the Reinvent the Toilet Challenge to generate and support new approaches for toilet technologies that safely and effective manage human waste. For the 4.5 billion people who lack safe sanitation today, these products have the potential to be life changing. Reinvented toilets can be installed anywhere, including in crowded urban areas. New sanitation solutions can work in regions that are flood-prone, or land, water, or money-poor. Sanitation has diversified beyond sewers, giving people and cities flexible new options.
Grants were awarded to 16 researchers around the world in two phases to those using innovative approaches—based on fundamental engineering processes—to develop new, promising technologies. In addition to these Reinvent the Toilet Challenge (RTTC) grants, we have made a range of other investments that are aligned with reinventing the toilet, and we are continuously seeking to expand our partnerships on this challenge.
The Reinvent the Toilet Challenge aimed to create a toilet that:
- Removes germs from human waste and recovers valuable resources such as energy, clean water, and nutrients.
- Operates “off the grid” without connections to water, sewer, or electrical lines.
- Costs less than US$.05 cents per user per day.
- Promotes sustainable and financially profitable sanitation services and businesses that operate in poor, urban settings.
- Is a truly aspirational next-generation product that everyone will want to use—in developed as well as developing nations.
In August 2012, the Bill & Melinda Gates Foundation hosted a two-day Reinvent the Toilet Fair at the foundation’s headquarters in Seattle, Washington. The fair showcased sanitation projects and Reinvent the Toilet Challenge prototypes. The fair brought together participants from 29 countries, including researchers, designers, investors, advocates, and representatives from the communities who could ultimately adopt these innovative approaches to sanitation.
In August 2013, the foundation announced the Reinvent the Toilet Challenge: China. The foundation invested US$5 million to support Chinese investigators to drive research, development, and production of the “next generation toilet.”
In October 2013, the Department of Biotechnology (DBT) under the Ministry of Science and Technology of the Government of India and the Bill & Melinda Gates Foundation, in collaboration with India’s Biotechnology Industry Research Assistance Council (BIRAC), launched the Reinvent the Toilet Challenge: India. This partnership supported sanitation research and development projects conducted by Indian individuals and organizations to extend affordable sanitation services to poor communities.
In March 2014, a second Reinvent the Toilet Fair was held in New Delhi, India, co-hosted by the Government of India’s Department of Biotechnology and the Bill & Melinda Gates Foundation, with the support of India’s Ministry of Urban Development. India is uniquely positioned to be a global leader in the development of new sanitation technologies and a range of other innovative approaches to achieve sustainable gains in sanitation in India and abroad. The Reinvent the Toilet Fair: India aimed to stimulate discussion and spur partnerships to bring safe, affordable sanitation to the 2.5 billion people who lack access.
The Reinvent the Toilet Challenge: India is part of a broader partnership with the Gates Foundation and BIRAC to cooperate on the:
- reduction of maternal and child mortality and morbidity
- scientific and technical solutions for infectious diseases
- strengthening India’s scientific translation capacity
- scientific and technical advances related to agriculture
- scientific advancement in food and nutrition
