Bioplastics research has been trending in recent years and was chosen as one of the top ten emerging technologies for the year 2019. In this report, we review the various types of bio-based polymers, highlight recent progress in bioplastics research, and present an analysis of trends in research and inventions around bioplastics using data from CAS Content Collection. The paper will end with brief discussions of challenges and opportunities of bio-based polymers. The terms "bio-based polymers" and "bioplastics" are synonymous and will be used interchangeably in the paper.
