520 _ _ |a Due to ever increasing problems in waste management associated with conventional fuel-based plastics, the use of degradable alternative materials appears to be one of the most promising approaches to help prevent the excessive environmental pollution caused by fuel-based plastics disposal and accumulation.Most of the information about polymer degradation is primarily based on traditional plastics. While various reaction mechanisms and pathways are established for some plastics, the effects of environmental factors such as microorganisms, weathering, pH, water, and structural characteristics on the rate and final level of degradation for many bioplastics are not yet properly known. In environmental fate studies, it also remains uncertain whether polymers introduced into more complex matrices undergo physical breakdown into micro- or nanoparticles or simply transform into carbon dioxide, water, or microbial biomass, especially when degradation is slow.The selective labeling of carbon atoms within the polymer backbone, available in both 14C and its stable isotope variant, 13C, has simplified the interpretation of degradation studies. The need to study the fate of bioplastics prompted us to design a synthesis route, starting from C14-labeled lactic acid monomers, transitioning through lactide as an intermediate, and finally culminating in the production of poly 14C-lactic acid chains via a catalytic ring-opening polymerization reaction. Subsequently, after bioplastics conversion into microplastics, these selectively radiolabeled micro-bioplastics are employed for a degradation study in soils under defined conditions. Enhanced understanding of the fate of bioplastics can be achieved by tracking introduced 14C-labeled microplastics in soil up to their ultimate transformation into 14CO2, as a key main degradation product.In this poster, I will present a synthesis procedure and a setup that we want to use for 14C-labelled poly lactic acid production which subsequent will be used for degradation studies in soil environment
