The Bill and Melinda Gates Foundation sponsored Reinvent the Toilet Challenge (RTTC) Toilet Fair in New Delhi is a land-mark event bringing together researchers and practitioners developing innovative waste treatment technologies around the world. Holding the Fair in India in March 2014 is an excellent opportunity to link with India’s research and development community, and engage with Government officials, NGOs and the private sector that are working across India to address India’s huge sanitation opportunities and challenges.

Exhibits at the Fair are presenting radically new ways of tackling the human waste treatment challenge. All are putting on display early stage innovations for waste treatment and toilet systems. The RTI booth at the Fair (Booth #69) presents a technology and user interface prototype which meets the Gates Foundation RTTC criteria for a:

  • “Off-grid” system that does not require an external source of electricity, water or sewer.
  • Waste treatment system that treats pathogens on-site.
  • Affordable system that operates on no more than 5 cents per person / per day.
  • Aspirational waste treatment and toilet system that may have appeal for both developed and developing countries application.
The RTI Unit Fully Treats All Human Waste and Is 100% Off Grid – Requiring No External Power or Water.
