Abstract: The definition of bio-based plastics was introduced. Three determination methods of 14C content were summarized, including accelerator mass spectrometry (AMS), liquid scintillation-counter method (LSC), and Beta-ionization (BI). The advantages and disadvantages of the three kinds of method were compared. It was found that LSC was easier and more effective.
