Bioplastics are nowadays considered as a sustainable alternative to conventional polymers, especially for specific applications such as in agriculture which requires eco-friendly materials and, preferably, biodegradable polymers. EcoBioPlast will contribute to understand and to model the biotic and abiotic process of micro- and nano-bioplastics biodegradation and their impact on soil and aquatic ecosystems to conceive new efficient tools for integrated crop management, particularly for the development of more effective, stable, eco-friendly and with longer-acting plant protection products based on biocontrol agents. For this, EcoBioPlast will implement a multidisciplinary approach with the collaboration of two partners with expertise bio-based engineering polymers, plant biology, environmental microbiology and math expertises.
