10‑ft shipping container retrofitted as a BSFL rearing room for on‑site food‑waste valorization, with an insulated, washable interior and sealed envelope. An automated climate system maintains stable rearing conditions using controlled supply/exhaust ventilation and electric heating, guided by temperature and humidity sensors (typical BSFL operations target ~27 °C and commonly manage ~60–80% RH). Air‑quality monitoring (e.g., CO2, NH3) can be used for demand‑controlled ventilation and alarms. The unit includes rearing racks/trays usuable for wet substrates, enabling hygienic operation, easy cleaning, and data logging for process control.
