In the time period 2010 2015, the worldwide annual production plastics is very likely to surpass 300 million tons, 1, 2 requiring amounts of petroleum and leading to hundreds millions of tons ofCO2 in addition to health risks for the public to the release of other types of emissions. 1, 3 A large amount plastics (at least 40% of the total consumption) is used in -term applications, and the resulting waste can quickly to additional environmental damage unless adequate management systems are in place. For example, conventional plastics are harmful for terrestrial and animals as well as birds that tend to eat plastic residues;4 impacts could be reduced by plastics that are biodegradable microorganisms. In short, petrochemical plastics are sustainable and bio-based sustainable plastics should be to avoid problems caused by the petrochemical.
