We have been using the same toilet system for the past 200 years. The sewer system is safe and clean, but also resource intensive, and many countries cannot afford the water and energy needed. Can there be a new solution? That is the ambition of the International Organization for Standardization (ISO) project committee 305 that is working to define a standard for a new type of toilet, which could help meet Sustainable Development Goal (SDG) 6 on safe sanitation for all.
On the occasion of World Toilet Day 2017, Dr. Doulaye Koné, Chair of the ISO/PC 305 and Deputy Director, Water Sanitation and Hygiene Program at the Bill & Melinda Gates Foundation, explains more about the project.
