Toilet Tech Fair Tackles Global Sanitation Woes
Monday, March 24, 2014
Who would have expected a toilet to one day filter water, charge a cellphone or create charcoal to combat climate change?
These are lofty ambitions beyond what most of the world’s 2.5 billion people with no access to modern sanitation would expect. Yet, scientists and toilet innovators around the world say these are exactly the sort of goals needed to improve global public health amid challenges such as poverty, water scarcity and urban growth.
Scientists who accepted the Bill & Melinda Gates Foundation’s challenge to reinvent the toilet showcased their inventions in the Indian capital Saturday. The primary goal: to sanitize waste, use minimal water or electricity, and produce a usable product at low cost.
The World Bank estimates the annual global cost of poor sanitation at $260 billion, including loss of life, missed work, medical bills and other related factors. India alone accounts for $54 billion – more than the entire GDP of Kenya or Costa Rica.
