PBAT composting conditions not met
Fenómeno del problema
PBAT products do not fully degrade under the claimed composting conditions, and certification does not match reality.
Análisis de la causa
Difference between PBAT industrial composting and home composting conditions; temperature, humidity and microbial requirements; influence of product thickness; difference between certification test conditions and reality.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solución
①Clarify composting type and conditions; ②control thickness to comply with certification; ③representativeness of certification testing; ④consumer guidance labeling.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
The condition dependence of PBAT composting degradation must be clear; thickness is an important variable; labeling guidance avoids misuse.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
