2.5 billion people around the world do not have access to safe, affordable sanitation. For those that do have access, sanitation facilities are often bad for the environment. There is clearly a need to rethink sanitation — and to reinvent the toilet — for both developing and developed countries.
Here are five current Good Ideas relating to toilet innovation:
Gates Foundation chooses three winning designs in their “reinvent the toilet” competition. Economist http://econ.st/QGO6s7
The Humanure Project in India uses biogas generators to produce electricity from human waste. Dell Social Innovation Challenge 2nd place (of 4000) 2012. http://bit.ly/Af5vGu
Project SOIL in Haiti installs composting toilets which promote both health and agriculture. Forbes http://onforb.es/1aFJ7xf
A plastic $1.50 retrofit on pit latrines blocks bugs which spread disease. Popular Science Innovation 2013. http://bit.ly/1iqRjcR
Many new toilets have two handles or buttons for flush, one for a full flush and one for half a flush. This saves lots of water and helps the environment.
