Biopolymers: Making Materials Nature's Way

8 Little research has been done concerning the potential environmental impacts of biopolymers that are used in large quantities, It is possible that the widespread use of some biopolymers may have unanticipated effects on ecosystems or waste streams. It should be noted that some naturally occurring polymers have varying degrees of toxicit y.

biopolymers, that are microbial produced polyesters, have the same thermoplastic and water resistant qualities as synthetic plastics. It was concluded that, increasing the carbon to nitrogen (C:N) ratio in a chemical waste water treatment system increased specific polymer yield (i.e, the production of PHA s increased). Researchers have long

addition of biopolymers to synthetic polymers ensures susceptibility to microbial attack, Mali et al3. This leads to physical embrittlement of the polymer, leaving a porous and mechanically weakened polymer. Biopolymers also improve the hydophilicity of HDPE due to increased internal hydrogen bonding.

10% of plastics has been recycled. On the other hand, biopolymers converted into biomass with the help of living organisms which later use as manure in plants. Disposal of bio-waste in landfill creates environmental problems, due to the huge production of CO2 and NH3. Since the waste contains large amount of sugars,

Biodegradable Polymers

The breakdown of polymer materials takes place by microbial action, photo degradation, or chemical degradation. All three methods are categoriz. ed under biodegradation, as the end products are stable and found in nature. Many biopolymers can be dumped in landfills, composts, or soil. The materials will be broken down, only if


microbial spoilage the tendency is to use more natural compounds. The use of synthetic films has led to big ecological problems because this materials are non-biodegradable (Sabiha-Hanim and Siti-Norsafurah, 2012). The natural biopolymers that are used in food packaging have the advantages

Compostable plastics undergo biological degradation to give carbon dioxide, water, inorganic compounds and biomass at a rate consistent without leaving toxic residues [26]. The requirements of biopolymers in industrial composters are complete biodegradation and disintegration,

and biopolymers. Biodegradable polymers are the synthetic oil-based polymers that have inherent constituents like poly caprolactone, poly hydroxybutyrate and poly (vinyl alcohol) to ease degradation or are chemically modified to assist biodegradation and are eco-friendly. Biopolymers are naturally occurring polymers such as cellulose,

Some biopolymers have also gained public acceptance and are now being manufactured. For degradation of plastics micro-organisms should be studied extensively so that solid waste can be degraded. Thus, microbes play important role in degradation as well as manufacture of plastics.
