Samsung Electronics has announced that it has completed a project in collaboration with the Bill & Melinda Gates Foundation in response to the Reinvent the Toilet Challenge, culminating in the development of a prototype toilet that is safe and designed for household use.
Samsung Advanced Institute of Technology (SAIT), the research and development arm of Samsung Electronics, began working with the Bill & Melinda Gates Foundation on the reinvented toilet in 2019, and recently finished the development of core technologies for the toilet and successfully developed and tested a prototype.
The design was announced at the completion of the reinvented toilet project at SAIT in Suwon, Korea, was attended by Gyoyoung Jin, President and Head of SAIT; Doulaye Kone, Deputy Director, Water, Sanitation & Hygiene, and Sun Kim, Senior Program Officer, Water, Sanitation & Hygiene at the Bill & Melinda Gates Foundation; and Yong Chae Lee, External Advisor to the Foundation, along with the project’s participants from SAIT.
Samsung Electronics Vice Chairman Jay Y. Lee met with Bill Gates, co-chair of the Bill & Melinda Gates Foundation on August 16 to discuss the outcome of the reinvented toilet project and exchanged ideas regarding global social contribution initiatives. During the meeting, Bill Gates shared the philanthropic vision and ongoing initiatives of the Foundation and Vice Chairman Lee expressed his commitment to using Samsung’s technologies to help address the challenges facing humanity.
Samsung plans to offer royalty-free licenses of patents related to the project to developing countries during the commercialization stage. Samsung will also continue to provide close consultation to the Bill & Melinda Gates Foundation to help bring the technologies to mass production. The two organizations will work together to identify industry partners willing to commercialize the technology, after making the design more efficient for mass production.
During three years of research and development, SAIT worked on the basic design and developed the component and modular technology, leading to the successful development of a prototype for household use. The product is energy-efficient with effluent treatment capability, and meets the performance required by the Bill & Melinda Gates Foundation for commercialization for a household-use reinvented toilet.
The core technologies developed by Samsung include heat-treatment and bioprocessing technologies to kill pathogens from human waste and make the released effluent and solids safe for the environment. The system enables the treated water to be fully recycled. Solid waste is dehydrated, dried and combusted into ashes, while liquid waste is treated through a biological purification process.
Launched in 2011, the Reinvent the Toilet Challenge is the Bill & Melinda Gates Foundation’s initiative to develop transformative toilet technologies that can safely and effectively manage human waste.
According to the World Health Organization and UNICEF, about 3.6 billion people are forced to use unsafe sanitation facilities, resulting in half a million children under age 5 dying every year from diarrheal diseases caused by limited access to safe water and hygiene.
