Fargreen is a for-profit social enterprise in Vietnam that turns rice straw—burned after harvest—into mushrooms and farmers' income. Founder Trang Tran was the first in her family to attend university, went abroad and earned an MBA (Colorado State University, Global Social & Sustainable Enterprises). She grew up in Hanoi amid the smoke of rice-straw burning and knew its harm firsthand. Vietnam produces about 40 million tons of rice a year and, as a byproduct, over 20 million tons of rice straw, most of which is burned in the fields, causing toxic smoke, greenhouse gases, health harm and vision-blocking traffic accidents. In 2013 she ran a small pilot with biologist Thuy Dao and formally launched Fargreen in 2015. The model is a closed loop—buying rice straw from farmers to stop the burning, growing mushrooms on it as the sole substrate, and returning the spent straw to the fields as biofertilizer. Greenhouses are provided in installments with no down payment. Rice is grown twice a year, and in between many farmers migrate for work, but mushrooms generate income year-round, so they need not leave home. From an initial 10 farmers (Hai Duong province), it grew to about 50 farmers (Thai Binh province) by 2019. Farmers' income is said to rise 50–70%.

Fargreen: Turning burned rice straw into mushrooms and income. The letter is B; certainty is medium. Unconfirmed concerns are placed under “Watching.” (As of 2026-Q2; estimate based on public information.)
Main narrative
One person’s story (N1)
+ before → after
Vietnamese rice farmers living on under $3 a day could harvest rice only twice a year, and migrated to cities for income in between. Rice straw was routinely burned, and its smoke ate away at their own lungs and neighbors' health. After partnering with Fargreen, they grow mushrooms year-round on the very straw they would have burned, and receive reliable monthly payment. Income rose 50–70%, and many no longer need to leave home to migrate for work. The spent straw becomes biofertilizer returned to the fields, reducing dependence on chemical fertilizer.

- Expansion to 1,000 farmers and +50% income; switching from chemical to biofertilizer; export via drying and salting; a biofertilizer business. In 2021 it co-founded the Fargreen Global Initiative in Vienna.
A second look
The core plus is year-round income for poor rice farmers and the air, health and decarbonization from stopping rice-straw burning (People, Nature), independently backed by Echoing Green, TED, Foreign Policy and UNDP BCtA. On the other hand, the scale is only dozens of farmers, and scaling difficulty is noted. Income rise and GHG reduction center on self/program reporting, and independent verification is 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
