Building a new era of non-sewered, safely managed sanitation for all
More than 3.5 billion people—close to half of the world’s population—use unsafe sanitation facilities and services. Starting with the launch of the Reinvented Toilet Challenge in 2011, our initiative for transformative technologies and commercialization has focused on accelerating the development and commercialization of safe, sustainable, and inclusive sanitation solutions for the world’s poorest people. We focus on two primary innovations: the off-grid, pathogen-killing reinvented toilet, and the omni-processor, a community-scale, human waste treatment facility.
Together with scientists, engineers, product designers, manufacturers, distributors, utilities, and governments, we are investing in demonstrating transformative sanitation technologies and products and bringing them to the markets where they are needed most, starting in South Africa, Senegal, China, India, and Thailand. The International Standards Organization and its country members are paving the way to market adoption by supporting the implementation of ISO 30500, which defines the operational requirements for reinvented toilets and omni-processors as well as for other existing and future standalone sanitation technologies that don’t require sewer connections. The standard also sets targets for safety, processing capability, and performance.
