Designed to be lost, these devices represent a persistent, low-recovery plastic stream with no practical end-of-life solution. Commercial biodegradable alternatives exist (e.g., Vaisala RS41 BioCover), but at USD 120–250 per unit, large-scale adoption remains economically unfeasible for China's national meteorological network. BioSonde engineers Halomonas sp. LA5 to produce polyhydroxyalkanoate (PHA) bioplastic from waste PET-derived ethylene glycol (EG). The resulting PHA is formed into lightweight, marine-biodegradable radiosonde shells — a locally manufacturable, low-cost alternative designed for national-scale deployment.
