Residual microplastics from PLA composting degradation
Fenómeno del problema
After industrial composting, PLA still has tiny particles remaining that are not completely degraded.
Análisis de la causa
The composting conditions or time are insufficient and PLA is not 100% degraded; crystalline PLA is difficult to degrade.
Solución
Extend the composting time to ensure complete degradation; amorphous PLA is easier to completely degrade.
Conclusión clave
PLA composting residue is a problem that needs to be considered.
