Great video! by Water For People, sure there are a lot of little details not mentioned, but you can not do better for a 5 minute video.
Oklahoma State University Professor AJ Johannes has a dirty job. Along with his colleagues, Johannes is reinventing the toilet with funding from the Bill and Melinda Gates Foundation. Through his research, Johannes and his team have the potential to affect 2.5 million people without modern plumbing.

A great video to watch while waiting to see the recording of Rose George when she spoke at Ted 2013
Rose George thinks, researches, writes and talks about sanitation. Diarrhea is a weapon of mass destruction, says the UK-based journalist and author, and a lack of access to toilets is at the root of our biggest public health crisis. In 2012, two out of five of the world’s population had nowhere sanitary to go.
The key to turning around this problem is to “stop putting the toilet behind a locked door,” says George. Let’s drop the pretense of “water-related diseases” and call out the cause of myriad afflictions around the world — “poop-related diseases” that are preventable with a basic toilet. Once we do, we can start using human waste for good.
George explores the problem in her book The Big Necessity: The Unmentionable World of Human Waste and Why It Matters and in a fabulous special issue of Colors magazine called “Shit: A Survival Guide.”

Waterless Urinals do not require water for flushing and can be promoted at homes, institutions and public places to save water, energy and to harvest urine as a resource. Reduction in infrastructure required for water supply and waste water treatment is also a spinoff arising from installing waterless urinals. The concept, founded on the principles of ecological sanitation helps in preventing environmental damage caused by conventional flush sanitation systems.
In recent years, Human Urine has been identified as a potential resource that can be beneficially used for agriculture and industrial purposes. Human urine contains significant portion of essential plant nutrients such as nitrogen, phosphate and potassium excreted by human beings. Urine and faeces can also be separated employing systems such as urine diverting toilets. In the light of diminishing world’s phosphate and oil reserves which determine availability as well as pricing of mineral fertilisers, harvesting urine for reuse in agriculture assumes significant importance. Akin to the movement for harvesting rain water, urine harvesting is a concept which could have huge implications for resource conservation.

Dr. Yu-Ling Cheng delivers a great overview of the current state of sanitatio and gives an over of her current efforts. She speaks of how she came to understand it to be essential to be part of the sanitation solution. She is addressing a group of student on the cusp of pick paths to travel starting colleges. She delivers a message that will ring true many regardless of age and path now traveling.
Dr. Yu-Ling Cheng is the Director of the Centre for Global Engineering (CGEN) and Professor of Chemical Engineering and Applied Chemistry at the University Of Toronto. CGEN was established in 2009 to be the focal point and major driver in preparing engineering graduates to meet challenges, responsibilities and opportunities in a globally sustainable future. Under her leadership, CGEN is developing new courses and academic programs in global engineering. She also leads new global engineering research initiatives, most notably a project under the “Re-invent the Toilet” challenge posed by the Bill and Melinda Gates Foundation.
Aside from her interests in global engineering, Professor Cheng’s research interests have centered around drug delivery, and the understanding of transport processes in polymeric and physiologic systems. She is a member the Teaching Academy, the highest honour for teaching at the University of Toronto. She also serves on the Board of Directors for Academics Without Borders, an NGO whose mission is to enhance higher education capacity in developing countries.
