Residual microplastics from PLA composting degradation
Problem Phenomenon
After industrial composting, PLA still has tiny particles remaining that are not completely degraded.
Cause Analysis
The composting conditions or time are insufficient and PLA is not 100% degraded; crystalline PLA is difficult to degrade.
Solution
Extend the composting time to ensure complete degradation; amorphous PLA is easier to completely degrade.
Key Takeaway
PLA composting residue is a problem that needs to be considered.
