Reinvent the Toilet Fair Program and Exhibitor Guide
14-15 August 2012, Seattle, USA

The Reinvent the Toilet Fair showcased innovations from around the world that are creating a new vision for the next generation of sanitation.

The fair aimed to inspire collaboration around a shared mission of delivering a reinvented toilet for the 2.5 billion people worldwide who don’t have access to safe and affordable sanitation.

The fair featured the foundation’s Water, Sanitation & Hygiene team’s earliest technology bets — most of the work presented received funding just over a year ago. During that time, grantees and partners have made some promising progress. The exhibits include efforts to reinvent the toilet, and approaches to improve the collection, treatment, and disposal of human waste. The fair was meant to spur partnerships and conversations about how we can work together to bring sanitation to those who need it most.

This library entry contains two documents, the program and the Exhibitor Guide.
