Thebio-based economy requires a sustainable utilization of bioresources forproduction of a range of products, including pulp, paper, chemicals, biofueland bioplastics. Currently, various types of bioplastics are producedindustrially, competing in performance and price with the conventionalfossil-oil based plastics. However, there is also a major interest in utilizingnon-food crops, such as lignocellulosics, for production of drop-in polymers ornew dedicated bioplastics. Lignocellulosic resources have a potential toreplace plastics and materials, which have been traditionally based on fossilresources. This is important, as the development of high performance bio-basedand renewable materials is one important factor for sustainable growth of thebio-based industry. However, production of bioplastics from forestry biomassrequires a dedicated fractionation into the major components, i.e. cellulose,hemicelluloses and lignin, effective purification processes and cost-effectiveroutes for conversion into monomers and platform molecules, utilized as a basisfor bioplastics production. These processes are now technologically demandingand not profitable. The intention of this work was thus to review the currentadvances that have been made during the years within fractionation andpurification of lignocelluloses and the processes that may feasible forproduction of bioplastics, based on wood components.
