The Sanergy Collaborative (Fresh Life): Sanitation in slums, and a cycle turning waste into fertilizer. In Nairobi, 60% of the population lives in informal settlements (slums), and 60% of the city is not connected to sewers. With too few toilets, “flying toilets” — waste thrown away in plastic bags at night — spread, fouling waterways and inviting infectious disease. In Mathare, an average of 85 households share one toilet, and the burden falls heavily on women and girls. Sanergy (Fresh Life) was born in 2011 from an MIT business-plan contest. It has local residents hold clean, low-cost container-based “Fresh Life Toilets” as a “franchise” (over 1,200 operators), regularly collects the accumulated waste, and at Regen Organics turns it into organic fertilizer and insect-derived feed to sell to farmers — building a cycle. Now over 6,000 toilets deliver safe toilets to more than 250,000 people every day. The letter is B; certainty is medium. Unconfirmed concerns are placed under “Watching.” (As of 2026-Q2; estimate based on public information.)

One person’s story (N1)
+ before → after
A slum resident buys one Fresh Life toilet and makes a business of it as a Fresh Life Operator — a clean toilet usable for about ¥5 a time replaces the plastic bag on the night road and brings safety and dignity, especially to women and girls. The collected waste becomes organic fertilizer, and about 10,000 farmers are said to have recorded a 30% yield increase.

Positive / negative effects
+ effects
- Berkeley (Haas / California Management Review) analyzed it as a case study, and impact investors and development finance institutions such as Acumen, Novastar, and Finnfund invested. It is also listed in the University of Oxford GO Lab database.P1 academic/case study / Berkeley Haas Case Series
− effects (confirmed)
- No confirmed −.
- Independent verification of sanitation/health outcomes; the business's financial sustainability
A second look
Figures such as users (250,000/day) and a 30% yield increase for farmers are mainly tallies from the company and its investors, and independent third-party measurement of effects is still limited. The business's financial sustainability (profitability) has also long been a challenge.

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 story 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-Q2 | Back to top
