Navailles-Angos, Pyrénées-Atlantiques, France

What was done

The commune of Navailles-Angos (Pyrénées-Atlantiques, France) installed a hen coop attached to its school as a closed-loop waste-reduction and educational measure.

The arrangement is simple and self-contained: the school canteen's food scraps are fed to the hens kept in the school coop, and the eggs the hens lay are collected and used by the canteen. Food waste that would have gone to collection instead cycles through the hens and partly returns as food.

Why this case matters

The school coop is a distinct sub-type of the collective model. It does not depend on residents at all — the institution is both the scrap producer and the carer — which removes the rota-governance problem that affects neighbourhood communal coops. It also adds an educational dimension: pupils see waste, animals and food as a connected cycle.

What a replicating school or commune should know

• A school canteen is an ideal closed loop. The canteen produces a steady, predictable scrap stream and has staff present daily — so the hardest parts of the collective model (reliable feeding, daily care) are solved by the institution's existing routine.
• Eggs returning to the canteen close the loop visibly. The waste literally comes back as food, which is both practically efficient and a strong teaching point.
• Watch the scrap-to-hen ratio. A canteen can generate far more food waste than a small flock can eat — the hens handle a portion, not all of it; pair the coop with composting for the surplus.
• Holiday cover must be planned. School coops need a clear arrangement for school holidays (staff rota, or families taking turns).

Honest reading

Outcome recorded as success as a functioning closed-loop installation; the consulted source describes the arrangement rather than quantifying diverted tonnage, so the waste outcome is qualitative here. The value of the case is the model — institution-run, closed-loop, no resident rota required.
