Sanivation is a social enterprise launched in 2011 in Naivasha, Kenya, by Andrew Foote and Emily Woods, linking sanitation and fuel in a single loop. In Kenya only about one in three can use a decent toilet, and waste washed by rain from full latrines enters rivers, causing diarrhea and cholera (according to WaterAid, about 5,000 children die a year in Kenya from dirty water and poor sanitation). Sanivation installs container-based 'Blue Box' toilets in homes without sewers (maintained for $2–7 a month) and collects the waste twice a week. At a treatment site it heats the waste above 70°C with solar heat to kill pathogens, mixes it with sawdust, rice husks and rose-farm waste, and turns it into odorless fuel briquettes (a charcoal substitute, 'charcoal for the family'). It now also operates a fecal-sludge treatment plant with the government and has expanded into the Kakuma refugee camp. The CDC has partnered since 2013, verifying how well solar treatment removes pathogens.

Main narrative
One person’s story (N1)
+ A single story
Rain washed waste from full latrines into rivers, and diarrhea and cholera recurred. The children of Ms. Nduta, a mother of three, frequently suffered stomach pain and diarrhea. After using a $2-a-month Blue Box toilet and stopping the shared latrine, the children were freed from diarrhea. 'It's so clean and odorless that I keep it in the children's room,' Nduta says. In Kenya one in three can use a decent toilet, and 5,000 children die a year from dirty water and sanitation (WaterAid).

A second look
The plus has two faces. On the People side—it brings dignified, hygienic toilets and reduced diarrhea and cholera to the poor without sewers (indeed, the Nduta family stopped using a shared latrine and the children were freed from diarrhea). On the Nature side—the charcoal-substitute fuel reduces deforestation (one ton of briquettes saves 88 trees) and creates a loop turning excrement into a resource. Partnerships with CDC/UNHCR/USAID/WaterAid provide backing. Caveats: the household-toilet scale is still small (initially a few hundred homes), and as a for-profit it is shifting its footing toward the government treatment-plant model for sustainability. Recognizing the genuine plus on both People and Nature sides, B/medium.

How to read this assessment
- Reachable upper bound (ceiling): a confirmed − sets the ceiling, and independently verified + decide the position within it. + do not cancel out −.
- The weight of evidence is not symmetric: only confirmed − are counted; the volume of disputes or allegations goes under “Watching.” + are counted from independent evidence, while an organization’s own PR is treated as “reference.”
- Size is not value: scale is not used in the assessment. Matters that stay within money or competition—investors, shareholders, sanctions, trade secrets—are also excluded.
- The letter (assessment) and certainty (how reliable the information is) are separate axes.
This is a translation; the Japanese version is authoritative. The assessments here are generated automatically by AI based on published criteria. The operator does not alter individual results. Because they are AI-generated they may contain errors, and they are opinion and commentary, not statements of fact. Where evidence is insufficient, the entry is marked “On hold.” Requests for correction are accepted via the form.
Terms: Narrative Value = an assessment (A–G) of the distance between the narrative an organization tells and its reality / Ceiling meter = a visualization of the reachable upper bound / Watching = unconfirmed matters not counted / Protected stakeholders = people, animals, nature, and future generations. | Generated by: AI | As of: 2026-Q3 | Back to top
