Abstract Purpose Bioplastics are a growing field, but with their expansion come unique environmental issues associated with the cultivation and processing of feedstocks. Availability of appropriate, high-quality data is a problem in life cycle assessment (LCA) of biopolymers and other bio-based materials that limits the accuracy and usefulness of study results. It is therefore critical that these data gaps be closed. To determine what data is needed to close these gaps, this study reviews currently available life cycle inventory data for biopolymer feedstocks and assesses the data quality for the selected feedstocks of corn, sugarcane, and soy. Methods Life cycle inventory databases and relevant publications were searched for appropriate data, and the results collected into a summary table. The quality review was conducted using a pedigree matrix type scoring system which was adapted from the ILCD handbook, and an overall quality score for each dataset was calculated based on the matrix scores. Results A total of 287 datasets were collected during the review for a total of 22 different feedstocks. The majority of these datasets are from Europe and the USA, with most of Asia, the Middle East, and Africa having very limited data available. Conclusions From the quality analysis, it was determined that more datasets that capture regional variations in crop cultivation are needed, as well as more data on land use change.
