Among the commodity chemicals, polymers for plastics are becoming independent for our
modern lifestyle (Andrady and Neal, 2009). Plastic have transformed our everyday life and
their usage is increasing. Based on the report from Plastic EU 2009, the average annual
increase of plastic production and consumption is 9% globally (PlasticsEurope, 2009). The
plastic demand in EU was 48.5 million tones in 2008, of which 75% was composed by mainly
five high volume families- polyethylene (PE), polypropylene (PP), polyvinylchloride (PVC),
polystyrene (PS) and polyethylene terephthalate (PET). Majority of them are produced by
chemical synthesis starting with petroleum feedstocks. These synthesized plastics are
durable which make them resistant to biological degradation. Due to the toxic additives, for
example, plasticizers like adipates and phthalate, burning plastic can release toxic
pollutants. And the manufacturing of chemical industrial processes often creates
environmental hazards. Due to the concerns over the climate change, limitation of the fossil
carbon source and environmental mitigation, there are renewed interests in bioplastics.
