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.

…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.”

When looking at sanitation/wastewater treatment and making it economically feasible for more parts of the world, this is very interesting research. Some will say it has roots in the fact that there is “gold” in out crap…

…On May 1, a panel of judges awarded the $100,000 National University Clean Energy Business Challenge prize to the Stanford team for its project to convert nitrogen waste into nitrous oxide that is then used for clean power generation….
A new process for the removal of nitrogen from wastewater is introduced. The process involves three steps: (1) partial nitrification of NH4+ to NO2−; (2) partial anoxic reduction of NO2− to N2O; and (3) N2O conversion to N2 with energy recovery by either catalytic decomposition to N2 and O2 or use of N2O to oxidize biogas CH4. Steps 1 and 3 have been previously established at full-scale. Accordingly, bench-scale experiments focused on step 2. Two strategies were evaluated and found to be effective: in the first, Fe(II) was used to abiotically reduce NO2− to N2O; in the second, COD stored as polyhydroxybutyrate (PHB) was used as the electron donor for partial heterotrophic reduction of NO2− to N2O. ….
Normally, we want to discourage these gases from forming,” said Craig Criddle, a professor of civil and environmental engineering and senior fellow at the Woods Institute for the Environment at Stanford. “But by encouraging the formation of nitrous oxide, we can remove harmful nitrogen from the water and simultaneously increase methane production for use as fuel.
- Total N2O emissions-which are believed to come primarily from nitrogen fertilizers used in agricultural production-would account for about 8 percent of California’s total greenhouse gas emissions. (familysurvivalprotocol.com)
