Jack Sim

Jack Sim is globally renowned as Mr Toilet. Jack Sim grew up in a slum in Singapore and although he did not have a university degree, this did not stop him from starting a series of profitable businesses. He retired from his businesses at the age of forty to dedicate himself to humanitarian causes. When he saw 2.6 billions people without proper sanitation, he founded the World Toilet Organization in 2001 and transformed the taboo of Toilets and Sanitation into a media darling mobilizing politicians, governments, celebrities and funds to give Sanitation its own agenda on the global stage. Jack graduated at the age of fifty-six with a Master in Public Policy in Singapore and later from Singularity University in the United States of America. He is an Adjunct Associate Professor at Lee Kuan Yew School of Public Policy and Fellow at Singapore University of Social Science.

World Toilet Organization

Jack Sim created the World Toilet Organization (WTO) to promote safe sanitation and hygiene, prevent excreta contamination of rivers and the environment, and to promote public health policies. The organization is the global body that champions better toilet environments. It is one of the few organizations to focus on toilets instead of water issues, which often receive more attention on the international development agenda.

The WTO was created as a global network and service platform to address the world sanitation crisis. WTO is the organizer of the World Toilet Summit and World Toilet Expo and Forum. Each summit addresses critical toilet and sanitation issues, including technologies, development, funding, maintenance, social entrepreneurship, capacity building and research. WTO declared 19 November as World Toilet Day, thus increasing awareness and generating local action for better sanitation.
