title = "Biodegradability of PLA in compost environment",
abstract = "Considering to environment issues, PLA is one of the most popular plastic and commonly used. This study is going to study the biodegradability after produced by compression molding and buried the specimens in the soil and compost condition within 7 weeks. The specimens was produced and followed pattern as following ASTM D882. Specimens are tested the changes of molecular weight, thermal properties and appearance week by week. The results show that PLA could be dissolved and disintegrated in the period. For the thermal properties, the decomposition temperature, Tg and Tm are all decreased by week and week. Molecular weight is conducted by GPC, it shows the molecular weight are dramatic decreasing from 115K to 5.1K of Mw within 7 weeks. PLA happens to absorbed moister, crystallized in high temperature, debonding, cracks, separated pieces, and disintegrated, and finally dissolved in the environment. So the PLA specimens are verified that PLA can absolutely and completely disintegration in the compost environment.",
