Bioplastics are being invested and applied in production and consumption in life. The reason why plastic pollution is happening is alarming, so many countries around the world have used bioplastics – bioplastics as a solution to the current plastic waste situation.
So what is bioplastic, why is bioplastic important in the production of replacing traditional plastic. Are all bioplastics fully biodegradable? Let’s find out more deeply with Biopolymer through the following article.
1.What is Bioplastic?
Currently, there is no official concept of bioplastics, but according to the definition of the European Bioplastic Association (European Bioplastics): Bioplastic is a group of different materials, divided into 3 groups main:
- Group 1: Bio-based plastics
- Group 2: Biodegradable plastics
- Group 3: Bio-based and biodegradable plastics
2. Are bioplastics as biodegradable as we often think?
In fact, bioplastics are divided into 3 main groups, with different origins, structural characteristics, and biodegradability, so there are many differences.
2.1. Bio-based plastics
Bio-based plastic is a type of plastic made from materials of biological origin such as tapioca, cornstarch, bagasse, coffee grounds, etc. During the production process, these materials will ferment into bioethanol. Then continue to synthesize directly and indirectly to become Ethylene and have the same properties as traditional plastic PP, PE, PET.
Popular bio-based plastics on the market today include Bio-PE, Bio-PP, Bio-PVS, Bio-PET, Bio-PA, Bio-PTT. Even though it is a plastic of biological origin, in terms of its nature, Bio-based plastic is completely non-biodegradable, but only degradable.
2.2 Biodegradable plastic
This is a biodegradable plastic that is derived from fossil fuels. The most commonly used raw materials are alcohols such as 1,4-butanediol; 1,3-propanediol is synthesized from chemicals of fossil origin. Biodegradable plastics popular on the market today include: PBAT, PCL, PBS and PEF.
2.3. Bio-based and biodegradable plastic
This is a plastic of both biological origin and the ability to biodegrade into CO2, H2O, and humus under the influence of microorganisms. To get this great product, it is because in the process of metabolism, biological materials such as starch, sugar, etc. have been fermented under the action of microorganisms or by physical action to become Lactic Acid. . After that, it will continue to undergo polymerization into molecules with Acid Polylactide chains that can decompose into H20, CO2.
The concept of biodegradation is the mechanism by which plastic is decomposed based on the action of microorganisms (bacteria, fungi, algae) into H20, CO2 (or CH4), mineral salts and biomass (Biomass). Depending on biological materials, environmental conditions, decomposition time may vary, for example PHA: 18 – 300 days, PLA: 28 – 98 days. Popular biodegradable plastics on the market today include: PLA, PHA, PBS, TPS.
3. Current application of bioplastics in production
Bioplastics in manufacturing can also be processed in ways very similar to petrochemical plastics such as injection molding, extrusion and heat forming. To improve their tensile strength, bioplastic polymers can be blended with their copolymers or with other polymers.
Products are biodegradable and short-lived.

Some products that Biopolymer is producing
In addition to producing bio-plastics from coffee grounds, we also produce products that are highly applicable in life such as:
- Home Application: mugs, mugs, thermos flasks, etc.
- Personal Care: masks, toothbrushes, combs, toothpicks, etc.
- Furniture: tables, chairs, potted plants,…
- F&B: spoon, fork, knife
- Others: pens, cosmetic jars, …
