An increase in microplastics concentration in natural systems raised an effort to replace conventional plastics with biodegradable plastics. Paradoxically, their use causes the rapid formation of micro-bioplastics because soil conditions often lead to biofragmentation than biodegradation. This problem was overlooked, and relevant studies are missing. Here, we propose a series of experiments to clarify the effect of poly-3-hydroxybutyrate particles on soil biota and properties. The results will be compared with the conventional PET microplastics.

The aim of the project is to create a competition for student research grants and its pilot verification. The creation of a new competition will contribute to the development of cross-sectional skills of doctoral students, and thus acquire competencies for work in science and research in the future and increase their success in submitting scientific projects to national and international competitions.
