  • Title: Biological Mass Production of Biodegradable Plastic Raw Materials
    (Research Prof. Dae-Yeong Jung)


    While plastics have been cited as the main cause of environmental pollution due to the fact that they cannot degrade over a span of decades, biodegradable bioplastics are degraded by microbes in the ground and are environmentally friendly materials. More than five dicarboxylic acid-based materials including itaconic acid, which are used as raw materials for biodegradable bioplastics, are included in the top ranked raw materials selected by US DOE (Department of Energy)...
