…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….

They are reinventing the toilet -
For someone who makes 1 dollar a day, with little water to be used for sanitation, in challenging locations, having a lack of space, and no existing sewage system.
. . . . . . . . .
X-Runner is designed with the following principles / features:
- It must be desirable
- It is private / respects privacy and dignity – it is in the home
- The waste is easily transported from the home by the resident (not surprisingly the job falling to the women-typically)
- The toilet base is also the transportation system in the form of a wheel
- There is a central place for collecting the waste from multiple homes
- This central place is desirable to visit based on the ability to socialize with friends and the access to amenities
- This central collection point has it has a biodigester
- The waste is turned into a useful resources - energy and fertilize
- The energy is returned home from this same place making a complete circle

The Social Factors Impacting Use of EcoSan in Rural Indonesia report came out in June 2010.
The Study Starts of stating the fact that “Joint Monitoring Programme (JMP) 2010 data indicate that around 38% of the rural population has access to improved sanitation services and that open defecation remains a widespread practice for over 60 million Indonesians. “
With a majority of Indonesia being Muslims the study include a a look at Muslim teaching on the subject of sanitation. “The study objective was to identify the social, religious, cultural and gender-related factors which inﬂuence rural people’s attitudes towards urine and excreta-based fertilizers in general and the EcoSan urine diversion system in particular. It doe not pretend to be anything but a modest study: ” the study does not seek to be a comprehensive reﬂection of the whole of Indonesia. Instead, it provides a preliminary assessment of attitudes towards EcoSan, and identiﬁ es some key drivers and inhibitors…” It survey 350 people in 5 out of 33 provinces included Muslims, Christians and respondents with traditional
beliefs. Four producers and retailers of excreta and urine based fertilizer were also identiﬁ ed and interviewed.
One of the key finding come in this paragraph:
“The study data show that this is not only a Muslim religious objection,
but that Christians also consider it difﬁcult to keep the excreta dry by not
using water above the disposal hole. While the percentage of Muslims who
considered it difﬁcult to keep the disposal hole dry was fairly constant, the
percentage of Christians who felt this way varied from 35% in Kulon Progo,
Central Java to 78% in East Sumba. This conﬁrms the assumption that
use of water for cleansing, where available, is also an Indonesian cultural
behavior that inhibits the use of a toilet system requiring dry storage. “
The study reports the researchers’ findings that more than “…80% of the respondents are willing to use urine or feces-based fertilizer.” The report goes on to say a similar number are willing to consume products from the fields using compost based fertilizer. The hard part, the study states, is only 50% of the people surveyed are will to to be involved in processing the urine and feces to make the compost. (I would like to know how this compares to other locations around the world 50% Seems high- a positive rather than negative - )
The study goes on to look at the roles/ potential roles men and women of a family unit have on
- selecting fertilizer for crops, and for selection installing,toilets for the family.
- selecting toilets installing them and composting waste from them.
The conclusions are complex. Hopefully organizations that want to just plop down ecosan units all anywhere in the will carefully read this short but informative report in its entirety. We must truly understand the people, if we / they are to have success with ecosan or any other viable alternative!

- Excreta-based fertilizers are still a sensitive issue for some
RESERVATIONS ABOUT USING ECOSAN TOILETS
- Gender Differences

technologies commonly used as toilets or as treatment systems in ecosan systems.”

They, GTZ, suggests the site http://www.susana.org/lang-en/working-groups for in depth information. SuSanA (Sustainable Sanitation Alliance) has formed working groups for a range topics centered on sanitation. Their admirable and hopefully achievable goal is to “…provide deliverables that underline the problems and opportunities …” for these topics. The working groups break out as follows:
