Abstract:
A laboratory scale simulated composting facility (as per ASTM D 5338) was designed and utilized to determine and evaluate the extent of degradation of polylactic acid (PLA), untreated wheat and soy straw and injection moulded composites of PLA-wheat straw (70:30) and PLA-soy straw (70:30). The outcomes of the study revealed the suitability of the test protocol, validity of the test system and defined the compostability of the composites of PLA with unmodified natural substrate. The study would help to design composites using modified soy straw and wheat straw as reinforcement/filler to satisfy ASTM D 6400 specifications.
