Using plastic bags is currently a problem that causes environmental experts to have a headache to find a solution. The use of alternative bags with paper or compostable materials is currently not effective because their cost and convenience are still not comparable to traditional plastic bags enough for people to change themselves. daily usage habits
.
Recently, scientists from the Research Center for Polymer Materials of Hanoi University of Science and Technology have successfully manufactured a type of plastic bag made from cassava flour combined with bioplastic, which is said to be a can replace hard-to-decompose plastic bags on the market today.
According to the test results, this new type of bag has greater durability and toughness than normal plastic bags. The main material to make bags is from tapioca, combined with bioplastics, so the cost is not too high, only 1.5 to 2 times larger than traditional plastic bags. And because it is made from eco-friendly bio-materials, after use, this bag can be buried and decomposed like normal biological waste.
The content of tapioca used in the production of this bag will account for 35-40%, the rest is biodegradable plastic. And with its durable and environmentally friendly characteristics, but the production cost is not so expensive, researchers from Hanoi University of Science and Technology are expected to be able to produce and sell this type of product to the market. domestic as well as to serve the needs of export to foreign countries.
In fact, in the world and in Vietnam, there have been many successful studies on the use of starch to produce environmentally friendly plastic bags. For example, in 2017, Nguyen Cam Kieu Thanh and Nguyen Cam Binh Minh used tapioca starch with nano silver to create a bag that is antibacterial, durable, tough but still degradable when taken away. bury.
Or as in some other countries around the world, potatoes have also been used as a source of starch to produce organic, biodegradable plastic bags in nature. However, most of the above inventions have not yet solved the problem of cost and price to an acceptable level as studied by Hanoi University of Science and Technology.
