Program

Although commonly distributed biodegradable plastics can be naturally degraded in soil microflora, marine microflora are generally much smaller abundance, therefore natural degradation is really slow time scale in the marine environment. Therefore, degradation steps both macroplastics and microplastics in marine environment are critical issues in the 21th century. Microplastics are one of the degradation products of all fragmented plastics and may be small to very small, including just beads, filament and foam, with a range of compositions. The presence of microplastics in the ecosystems has been reported in the scientific literature since the 1970’s, and there are growing concerns about potential effects in biota, but many pressing questions regarding their impacts remain unresolved.
The session highlights the latest progress in two kinds of topics; 1)Polymer degradation from land to marine environment, and new developments of sustainable materials, and 2) The microplastic research in the environmental fate, behavior, abundance, and also their effect for human life style.
