Chemical-based plastic harms living organisms and environments since it is non-degradable and has been accumulated both in land and water. Moreover, in the future, there will be no more petroleum to produce this chemical-based plastic. Therefore we need to find a new source to sustainably produce plastic which is friendly to environments. One of possible solutions is replacing this chemical plastic by bio-degradable plastic (hereafter bioplastic) which not only is renewable and non-toxic, but also have comparable physical chemical plastic.
