Sistema.bio (Sistema Biobolsa): Turning livestock manure into biogas and organic fertilizer. Smallholders grow about 70% of the world's food yet are bound by poverty and hit hardest by climate change. Meanwhile agriculture emits about a quarter of greenhouse gases, and many farmers cook with firewood or diesel and buy chemical fertilizer that depletes the soil. Sistema.bio (founded 2010 in central Mexico by Alex Eaton and Camilo Pagés) delivers low-cost, patented modular biodigesters with training and financing. Livestock manure and farm waste turn into biogas for cooking and heating (replacing firewood/diesel) and into soil-regenerating organic fertilizer “bioslurry,” while methane is captured. It has installed over 60,000 units, reaching about 370,000 people in 30 countries. It has manufacturing bases in Mexico, Colombia, Kenya, and India and partners with Danone, the Shell Foundation, BII, and AXA. 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 small dairy farm with four or five cows. The wife had cooked with firewood, breathed the smoke, spent time gathering wood, and bought chemical fertilizer for the field. With a biodigester, the manure turns into biogas, and the kitchen fire lights without firewood. The rest becomes bioslurry, an organic fertilizer that grows crops without depleting the soil. Smoke and spending drop, and methane is captured instead of escaping to the air.

+ effects
- Carbon/methane reduction is third-party verified under Gold Standard certification with digital MRV (measurement, reporting, verification), calculated at over 630,000 tons of CO2e a year. British International Investment, the Shell Foundation, AXA IM Alts, and others invested, and Danone signed an MOU to deploy it to 6,500 smallholder dairy farmers by 2030. ImpactAlpha and others report on it.P1 certification (Gold Standard) / Gold Standard / Danone / BII
− effects (confirmed)
- No confirmed −.
- Independent verification of income/health/gender benefits; long-term uptime after installation; performance differences by herd size/climate
A second look
Independent verification mainly covers carbon/methane reduction; the scale of farmers' income/health/gender benefits (less firewood, cooking time, fertilizer cost) is mainly company/partner tallies with limited independent outcome verification. Biodigester performance depends on herd size, temperature, and operation, and long-term uptime after installation is a question.

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
