Grand Challenge: Create the Next Generation of Sanitation Technologies

Create the Next Generation of Sanitation Technologies” is one of the new topics in Round 6 of the Grand Challenges Explorations grants, funded by the Bill & Melinda Gates Foundation. The Explorations are part of the Grand Challenges in Global Health initiative. Successful projects have the opportunity to receive a follow-on grant of US$ 1 million or more, and could eventually evolve into Grand Challenges project.


Areas for innovation to be considered in the sanitation challenge include:

  • Sanitation capture and containment technologies: improvements or alternatives to pit latrines.
  • Solutions to menstrual management and safe disposal of child feces.
  • Extraction and transportation innovations for hauling fecal sludge to transfer or disposal points.
  • Advancements in decentralized treatment technology for use at community, apartment block, town, and/or city scales.
  • Innovations in re-use of waste for agricultural, energy or industrial purposes at community and/or city level.

Other sanitation innovations, including but not limited to:

  • Improved temporary toilets that do not use chemicals requiring special disposal;
  • Low cost composting facilities requiring minimal user interaction with composted material.
