Bioplastics, biobased or biodegradable polymers, have begun to be adopted as an alternative to petroleum-based plastics. Despite their growing use, research on the occurrence of these materials in the environment as pollution is nascent. Here, we provide a library of bioplastic spectra known as the Bioplastic Library of Polymers (BLoP), intended to improve the detection of bioplastic materials in environmental samples by using Raman spectroscopy and attenuated total reflectance Fourier transform
