…An analysis of a former civilisation in the Amazon, nowadays Brazil, reveals concepts which enable a highly efficient handling of organic wastes. Terra Preta do Indio is the anthropogenic black soil that was produced by ancient cultures through the conversion of biowaste and faecal matter into long-term fertile soils. These soils have maintained high amounts of organic carbon even several thousand years after they were abandoned. It was recently discovered that around 10% of the originally infertile soils in the Amazon region was converted this way from around 7,000 until 500 years ago. Due to the accumulation of charred biomass and other organic residues, terra preta subsequently formed giving it a deep, distinctly dark and highly fertile soil layer.One of the surprising facts is that this soil is highly productive without adding fertiliser.
Recent research concludes that this culture had a superior sanitation and bio-waste system that was based on source separation of faecal matter, urine and clever additives particularly charcoal dust and treatment steps for the solids resulting in high yielding gardening. Additives included ground charcoal dust while the treatment and smell prevention started with anaerobic lactic-acid fermentation followed by vermicomposting.The generation of new Terra Preta (‘terra preta nova’) based on the safe treatment of human waste could be the basis for sustainable agriculture in the twenty-first century to produce food for billions of people….

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.”

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.
