What are some of the advantages and disadvantages of bioplastics



Nowadays, one of the consumers’ concerns is corporate social responsibility related to CO2 emissions, fossil fuel depletion, and other environmental issues. Therefore, the demand for bioplastic is increasing day by day. One plain proof is that some of the world's famous brands like Walmart are using biodegradable plastic rather than plastic from petroleum. So in today's article, let's find out what bioplastics are, their pros and cons as well as their application in real life. 

1. What are bioplastics?

1.1. Differentiating between disintegrating plastics and biodegradable plastics

Bioplastic lifecycle

Bioplastics include disintegrating plastics and biodegradable plastics. In fact, many people may mistake disintegrating plastics for biodegradable plastics and assume that any type of bioplastics will completely decompose in the environment. So, what are the differences between them?

Disintegrating plastics include the process of destroying the polymer molecular chains. Mixing plastic with additives (OXO degradable system) makes the polymer structure unstable, resulting in the molecular chain being destroyed but not completely decomposed.

Biodegradable plastics include the process of complete decomposition when discharged to the conditions of moisture, light, and microbiology ... when being decomposed, it will be converted into other structures.

To distinguish biodegradable plastics from disintegrating plastics, we can use solvents. Put the plastic film in the solvent called CH2Cl2, if the film is completely dissolved in the solvent, it is biodegradable plastics. If the film does not dissolve, it is disintegrating plastics or PE, PP plastic.

The structure of biodegradable plastic is similar to common plastics such as polyethylene, polypropylene, and polystyrene. In addition, the technologies used to process biodegradable plastics are similar to those used for common plastics, including extrusion, injection molding, blown films, and thermoforming.

1.2. What are bioplastics made of?

What are bioplastics made from

Bioplastics are made from renewable sources such as polylactic acid (PLA) and Polyhydroxyalkanoate (PHA), extracted from crops and vegetables such as corn, palm oil, soya, and potatoes. Besides, bioplastics can be synthesized from fossil fuels like aliphatic-aromatic co-polyester (PBAT). The mixing of biodegradable polyester and starch is called starch/synthetic biodegradable polymer blends.

The following materials are what is used to make bioplastic:

  • PBAT (polybutylene adipate terephthalate)
  • PBST (polybutylene succinate terephthalate)
  • PLA (Polylactic acid) PBS (Polybutylene succinate)
  • PCL (Polycaprolactone)
  • PHA (Polyhyroxyalkanoate)
  • TPS (Thermoplastic Starch)

1.3. What are the properties of bioplastics

Bioplastic advantages

Depending on the purpose of uses, manufacturers will produce bioplastic with the appropriate properties for final products. The major functions of bioplastics are:

  • Biodegradable within a short time period after use (normally 12 months), thus causing no harmful effects on the environment
  • High stiffness
  • Good elongation
  • Low melt flow index
  • High impact strength
  • Great gloss
  • - Keep moisture on the surface, resulting in longer food preservation
  • Anti UV, oxidation and moisture

2. What are some of the advantages and disadvantages of bioplastics?

2.1. What are the advantages of bioplastics?

Bioplastics will preserve the exhausting fossil fuel.

The production of bioplastics emits a smaller carbon footprint compared to traditional plastics.

Fast decomposition which happens in weeks to months.

Better for health (PLA and PHB) so they are suitable for the production of food packaging.

2.2. What are the disadvantages of bioplastics?

Are bioplastics a good alternative to traditional plastics? Not really. Because every coin has two sides and so do bioplastics. Below are some disadvantages of bioplastics we should take into consideration:

Because the main resources of bioplastics are crops, the fertilizers and pesticides used in growing the crops and the chemical processing needed to turn organic material into plastic will emit pollutants to the environment.

The land required for growing crops competes with land for food production. 

The price of bioplastics is more expensive than that of traditional plastics.

Some bioplastics require a specific disposal procedure and industrial composting which needs advanced machines and facilities. If the local authorities can not filter bioplastics from traditional plastics and put all of them in landfill, the biodegradability will be somewhat reduced. 

3. What can you make from bioplastic

The biodegradable plastic market has grown rapidly over the past 10 years, but it shares a relatively small amount. Biodegradable plastics such as starch and modified starch, polylactic acid, and aliphatic-aromatic co-polyesters, are currently used in a wide variety of niche applications, particularly for the production of rigid/flexible packaging, bags, sacks, and food contact products.

Currently, bioplastics are used to produce the following products:
