Starch based Bioplastics

Starch based Bioplastics

One of the most abundant renewable resource biodegradable polymers found in nature is starch.  These natural polymers can be derived from various agricultural resources including corn, wheat, and potatoes.  Starch polymers are usually found as micron sized granules, and are made of amylose and amylopectin.

Startch Bioplastics

As shown in above figure, amylose is a linear polymer with 200 – 2000 of anhydroglucose units. Amylopectic is is a brached polymer and contains 20- 30 anhydroglucose units.  The relative ratio of amylase and amylopectim in starch granules could vary with the source.  The highly ordered structure causes the starch granules to be highly crystalline.


Depending on the performance properties of the target product, starch can be blended with other renewable resource or conventional polymers.  For example, Mater Bi biodegradable bioplastics are made by blending starch with Polyesters.  Over the years, research was devoted to get starch based thermoplastics with better properties.  Errec et al has reported improved mechanical properties of starch thermoplastics that were blended with castor-oil-based polyurethanes.

Applications of Starch based bioplastics include disposable products such as shopping bags, bread bags and bait bags.

Biodegradable Polyhydroxyalkanoate Natural Polymer Applications

Biodegradable Polyhydroxyalkanoate Natural Polymer Applications

Biodegradable natural polymers such as PHB , PHBV and their copolymers are used in biomedical applications including sutures, pins, rods and drug delivery systems.

Biodegradable Polyhydroxyalkanoate Natural Polymer Applications

Biodegradable Polyhydroxyalkanoate Natural Polymer Structure

Polyhydroxyalkanoate Biodegradation

Depending on the composition, bacterial bioplastics degrade in about 1-6 months.  When exposed to enzymes or to the natural microorganisms in the environment, these natural polymers could undergo enzymatic hydrolysis or chemical hydrolysis yielding carbon dioxide and water.  The major factors that influence the degradation includes the chain composition, sample structure, thickness, crystallinity, morphology, temperature and pH.


Biodegradable Bioplastics: Polyhydroxyalkanoate Natural Polymers

Biodegradable Bioplastics: Polyhydroxyalkanoate Natural Polymers

Polyhydroxyalkanoates (PHA)s natural polymers have become one of the widely emerging bioplastics to be used in commercially applications, and are known as microbial polyesters or bacterial plastics.  PHAs belong to a family of biopolyesters produces by various microorganisms to yield polyesters with varying side-chain lengths. In addition to their biodegradability and biocompatibility, another widely recognized characteristic to PHAs includes chirality.  They exhibit highly stereoregular polymer backbones with R configuration.

Figure 1: General structure of Polyhydroxyalkanoates (PHA) Polymer Materials.

Poly-b-hydroxybutyrate (PHB) and poly(hydroxybutyrate-co-hydroxyvalerate)  polymer materials are the most studied polymers due to their attractive properties.  Depending on the type of microorganism, carbon source that the cells are grown on, fermentation conditions including the types of enzymes used.   The final properties of the PHAs primarily depend on the monomer composition, and monomer with C3-C5 typically yields thermoplastics, while C6-C14 chain length monomers yield elastomeric polymers.

PHB natural polymer is a melt processable, hydrophobic,  semi-crystalline polyester that  resembles properties of conventional thermoplastics such as polypropylene and polyethylene. As PHB is almost 80% crystalline, it exhibits a high melting point.  It has an excellent resistance to organic solvents, however its applications are limited due to its high stiffness and brittleness. Further, at processing temperatures, PHB tend to degrade rapidly minimizing its usefulness further.

poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (P(HB-co-HV)) is commercially available polyester (BioPolTM), and less stiff and brittle than PHB homopolymer, making it easier  to process.

PHAs can be modified to get less crystalline and improved physical properties by blending them with various other polymers such as polysaccharides, polyvinyl alcohol, polycaprolactone and polyvinyl chloride.

Miscibility of PHB with various polymers

Polylactic acid  (PLA) – immiscible

(PHBV) – miscible depending on the PHBV content

Polycaprolactone (PCL)  – immiscible

Polyethylene glycol (PEG)  – miscible

Polyvinyl alcohol (PVOH) – miscible depending on the PVOH content

Poly(ethylene oxide) – miscible


Bioplastics: Polylactide-co-glycolide Copolymers

Bioplastics: Polylactide-co-glycolide Copolymers

Polylactide (PLA), polyglycolide homopolymers (PGA), and polylactide-co-glycolide copolymers are the predominant biodegradable bioplastics that found applications in the biomedical field.

Earliest applications of these resins include sutures, bona fixation devices and scaffolds.  Due to the fine tuneability of the degradation rates depending on the molecular weight, molecular architecture and crystallinity, these polymers were extensively researched during the past few decades.

Polylactide-co-glycolide Bioplastic Degradation

Biodegradable polymers have become part of the solution to the growing problem of polymer waste management. Thus, many major plastic manufacturers have opened a product line with bioplastics mainly for disposable products including cutlery items, packaging films, and disposable grocery bags. However, to maximize the benefits, public needs to be educated on their proper disposal procedures.  This is due to the fact that in order to biodegrade rapidly, these resins have to be exposed to proper conditions such as in a composting facility.

The degradation behavior of biodegdarable polymers is also a very important in medical field especially in tissue engineering, and drug delivery. The polymers degradation behavior under biotic or abiotic conditions, non-toxicity of the degraded by-products, and mechanical strength are considered to be highly important in selecting the polymer for a special application. For example, in biomedical applications, if the polymeric material or its byproducts causes issues such as inflammation or infection, it couldn’t be used even the other properties are properly designed.

Polylactide-co-glycolide copolymers are one of the highly studied copolymers for biomaterial applications.  They can be copolymerized to get various molecular architectures to get a range of mechanical properties and degradation rates. Owing to the methyl group in PLA, they are more hydrophobic than PGA. Thus, PLA products degrade much slower in vivo by hydrolysis than PGA materials.  The degradation could takes from weeks to years depending on the initial polymer properties including, the molecular weight, crystallinity, shape and size, as well as the molecular architecture. Further, the carboxylic acid end groups may also auto catalyze the degradation.

Biodegradable Polymers :Polylactic Acid Applications

Polylactic acid biodegradable plant based polymeric based materials have shown various advantages over the conventional polymers. For example PLA fibers can be processes at lower temperature than PET fibers, lowering the energy input. Further, PLA based products can be processed using traditional operating equipments including blow molding, injection molding and extrusion.

Polylactic acid biodegradable plastics are widely used in variety of applications including drug delivery, structural support and in fibers and films.  Use of PLA based materials in medical applications including sutures, pins, rods are known for decades. Currently, PLA has found applications in food handling products such as lids, trays and paper coatings, packaging films, and fibers for textile products.


Polylactic acid properties

Polylactic acid properties

Crystallinity of polylactic acid resin depends on the relative proportions of the L- and D-Lactide in the polymer backbone.  Higher the optically pure monomer content, higher the crystallinity. The melting point of PLA could range from 140 – 185 C, and a blend of Pure PLLA and PDLA could reach as high as 230 C.

As you can see from the following Figure, PDLA can be synthesized starting from D_lactide, using special catalysts.



Mechanical properties of polylactic acid depends on the molecular weight, molecular architecture as well as the degree of crystallinity.



PLA resembles most of the properties on conventional thermoplastics including PET, and polystyrene (PS), opening possibilities to replace petroleum based thermoplastics in many applications.
