In modern times, straws are essential products in the world. While they bring convenience to people's lives, more and more plastic straws and similar discarded products begin to burden the environment. Under the pressure of environmental protection and plastic limit, conventional straws are facing challenges and are eliminated. It is urgent to replace them with eco-friendly straws; hence biodegradable PLA straws and paper straws have emerged. Today SOTON will take you to learn about the two giants of eco-friendly straws: PLA straws and paper straws.
PLA straws: PLA (polylactic acid) is a new type of biodegradable material, which is made from the starch materials proposed by renewable plant resources such as corn. Starch materials are saccharified to obtain glucose and then fermented with glucose and certain strains to produce high-purity lactic acid. Then synthesize polylactic acid with a certain molecular weight through chemical synthesis, and process it into shape, which has good biodegradability.
Are all paper straws biodegradable? Paper straws are made of food-grade paper, which can be degraded in the soil after a few months of use.
These two kinds of straws can be completely degraded by microorganisms in nature after use and finally produce carbon dioxide and water. Both of them directly enter the soil organic matter or are absorbed by plants, will not be discharged into the air, causing the greenhouse effect and polluting the environment. Thus, these two biodegradable drinking straws truly come from nature and return to nature!
First, look at the similarities:
1. Like our eco disposable cups, the natural material is non-toxic, highly breathable, and will not release any hazardous substances to the human body;
2. It can be completely decomposed by microorganisms after being composted and buried and will not cause any impact on the environment;
3. It can replace traditional plastic straws that use petroleum as raw material. The method of use is the same, but it is more environmentally friendly and healthier.
4. Since biodegradable straws are more expensive than plastic straws, they may also become an obstacle to developing the eco-friendly straws market.
Then, let's take a look at the differences between these two biodegradable straws:
PLA straws have a temperature resistance of -10°C to 80°C, which is closer to traditional plastic straws. They have the same physical properties as conventional plastic straws with higher stability. But their colors are simpler than that of paper straws;
The temperature tolerance of paper straws ranges from -10°C to 80°C, and it is easy to dissolve above 40°C, which will affect the taste of food. But it can be customized in different colors and can be used as decorations, which is more beautiful.
In summary, PLA straws and paper straws are the hottest biodegradable drinking straws at the moment, but each has its characteristics. Customers can choose different eco-friendly straws according to their needs. Finally, it is everyone's responsibility to care for the environment.
