We are aggressively focusing on this material at the moment.  So far biodegradable resin such as PLA, PHA (poly hydroxy alkanoate), starch based biodegradable resin, PBS (poly butylene succinate), PBAT (poly butylene adipate terephtharate) etc… have been supplied in the market although they are made from partly petroleum or edible biomass which also can be nutritious food for human beings.  This will be a problem since human population explosion may be one of the problems in the near future.   On the other hand, cellulose is non edible biomass resource and most abundant organic resource on earth.  Cellulose can be taken from all of plant including wood, waste wood, weed, root etc… The amount of cellulose is huge and it is more than the amount of petroleum.  We have made biodegradable resin from this cellulose.  It is basically thermoplastic cellulose.  Not to mention this material is also composed of 100 % nature biomass.  It should noted that even this material is expanded and supplied in huge quantity in the world market, it is not necessary to cut down new trees because they can be basically made from waste wood.  Therefore, we believe that this cellulose based biodegradable resin is most environmentally friendly biodegradable resin material.
