The functions and low costs of conventional plastics are of essence for our daily and modern life in these days. In the view of sustainability of our globe, we have to care about the emission of the global warming gas and spilling out of the plastics which potentially turned into microplastics. Biomass plastics being good alternatives for them, we still have been confronting some difficulties especially about the material procurement. Therefore, our company have been developing a novel production process for biomass plastics derived from wood pulp for paper making. <br>We had developed the technology for transforming wood pulp to ethanol which is material for ethylene by biochemical process with yeast. As a beginning of our project, we examined the reproducibility of the technology and manufactured pulp derived ethanol at small and large scale. The ethanol was converted to ethylene by a chemical process which was followed by the polymerization to polyethylene. Purification method that was established to obtain highly purified pulp derived ethanol employed pulp derived polyethylene production.<br>Manufacturing of pulp derived polylactic acid was also achieved. The raw lactic acid was also obtained by fermentation, whose yeast was replaced by lactic acid bacteria.
