Summary
This study reveals that the specific manufacturing and post-processing methods used to produce polylactic acid (PLA) significantly influence how quickly the material breaks down under controlled industrial composting conditions, indicating that processing choices are a key but underappreciated variable in PLA's real-world biodegradability.
Polymers
This study reveals that distinct processing and postprocessing methods can significantly affect the rate of disintegration of PLA during composting.
