Tiếng ViệtBioplastics are materials from different origins such as starch, rice husks, seaweed,… So where is Coffee Bio-composite really come from and how is the production process to create finished products from Coffee Bio-composite? Let’s find out the original of Coffee Bio-composite in the article below.
Original of popular bioplastics on the market
PLA (Polylactic Acid) plastic: made from the fermentation of corn starch by bacteria. Due to its hardness, elasticity and high strength, PLA is now widely used in the production of knives, spoons, forks, containers, trays… and medical products.
PHA (Polyhydroxyalkanoate) plastic: is also a bioplastic produced naturally by bacteria and genetically modified plant tissues. PHA is used a lot in food packaging and medicine such as: sutures, gauze, medicine shells…
Polysaccharides: commonly used to produce biodegradable polymers which are cellulose and starch. In addition, these polysaccharides are also often mixed with biodegradable polymers to create highly degradable, more environmentally friendly products.
Chitin/Chitosan: is a polymer of animal origin (shells of shrimp, crab shell, seashells), with good antibacterial, antifungal, antioxidant, and film-forming properties.
This type of plastic is widely used in daily life (bags, printing ink…) as well as in medicine (surgical sutures, implanted tissues…). However, like PHA, the current cost of Chitosan is still high.
Agar: A polymer produced from seaweed. Currently, Agar is a potential raw material to create bags and bottles that are easily degradable due to its ability to easily decompose in the water environment, being environmentally friendly.
Original of Coffee Bio-composite
An unexpected thing makes people surprised that original of Coffee Bio-composite come from coffee. Why and how did Biopolymer Vietnam turn a trivial source of material into an extremely environmentally friendly Coffee Bio-composite bioplastic?
Why does Biopolymer choose coffee as the main raw material for Coffee Bio-composite bioplastics?
Stemming from environmental responsibility in the midst of waste pollution, especially non-biodegradable fossil-based waste such as plastic. The Earth is facing alarms with calls for help from animals, plants and climate. Biopolymer wishes to develop a source of biological materials that bring practical meaning to the environment as well as contribute to build a sustainable economy.
- Vietnam – the second coffee producing country in the world
An extremely favorable thing that Biopolymer realizes is the abundant source of coffee in Vietnam – the country that ranks 2nd in the world in terms of coffee production and export. Drinks from coffee are widely popular, which means that the amount of waste from coffee being released into the environment is extremely large. Since then, coffee has become the original of Coffee Bio-composite today.
2. Are coffee grounds really harmless?
Another reason that the original coffee bio-composite comes from coffee grounds is because of the large amount of waste which is not completely beneficial when not handled properly.
A problem that few people know is that coffee grounds, if not handled properly, can be harmful to the environment. Typically, methane gas, which has 28 times greater global warming potential than carbon dioxide, generated from coffee grounds is the leading cause of the greenhouse effect. Although coffee grounds are also applied to many other things such as composting crops, personal care or deodorizing, etcThese are probably not enough to take advantage of the huge amount of coffee grounds out there.
3. Scientific significance is the decisive factor for the original of Coffee Bio-composite
Around the world, science and technology organizations have also announced that coffee grounds can be used to create cellulose or lactic acid as a premise to create bioplastics.
According to the journal Cellulose, coffee grounds are an ideal source for cellulose nanofibers, because about half their weight and volume are made up of cellulose.
With all the above reasons, Coffee grounds – a seemingly normal material, is now being used as the original of Coffee Bio-composite. Not only keeping the features of traditional PP/PE, Coffee Bio-composite resins also possess special characteristics of coffee grounds such as sterilization, natural dark brown color, and light coffee aroma.
The natural ingredients in Coffee Bio-composite account for more than 50%, so the product is less dependent on fossil materials which help the price be more reasonable.
Biopolymer believes that the origin of Coffee Bio-composite is the utilization of discarded coffee grounds, which not only helps develop an alternative source of raw materials to protect the environment, but also helps the world take advantage of available raw materials dealing with a significant part of waste to the environment.
