On February 19, 2020, the University of Oulu, Finland, announced that scientists from its Research Unit of Sustainable Chemistry have developed a new synthetic bioplastic that provides protection from ultraviolet (UV) radiation. In addition to its UV-light blocking capacity, the transparent bioplastic made from a biomass-based copolymer with bisfuran structure, the new bioplastic also has airtightness capabilities three to four times higher than polyethylene terephthalate (PET) plastic. The raw materials used in the production of this entirely biomass-based plastic are hydroxymethylfurfural (HMF) and furfural, which are biorefinery products derived from cellulose and hemicellulose. University of Oulu researchers chemically linked the two chemicals to create copolymer parts with bisfuran and furan-like structures. The research results have been published, and a patent application for the bioplastic has been filed for the new method developed.
