 Sanitation refers to a system that hygienically separates humans from harmful excreta and promotes its safe treatment and disposal. To date, sanitation issues have been focused on infrastructure and facility installation, environmental conservation for alleviation of water and soil contamination, and adverse health outcomes linked to unimproved sanitation. However, sanitation goes beyond technology, encompassing values spawned amidst humans and local communities, which can fall into the nexus of three components: Health, Materials, and Socio-Culture. Our observations of this nexus led to the creation of the Sanitation Triangle concept.

 This symposium brings this novel concept which is the culmination of our international research addressing global sanitation. We deliver each component of the Sanitation Triangle above, which comprises concepts and case studies. Notably, it showcases interdisciplinary and transdisciplinary research works involving a variety of local actors ranging from children and youth to local governments.

 Now, it is time to grab the Sanitation Triangle and embark on an enlightened quest through global sanitation.
