As the owner of a food processing plant in Long Bien District, Hanoi, her most painful Pham Thi Nhan is the packaging used to wrap and store their products. Using cheap foam boxes or bags is not safe for health, but polluting the environment. But containers of glass or containers are expensive and inconvenient for transportation, Nhan researched other containers to save money.
Recently, Pham Thi Nhan, as well as many other consumers, was delighted by the news that biodegradable nylon bags could replace traditional nylon bags.
Bio-degradable food bags come in a variety of sizes
At supermarkets, bio-degradable food bags produced by Vietnam are priced at between VND50,000 and VND90,000 / bag, and bags imported from Europe cost VND110,000 / coil. Nylon bag is usually white or transparent, smooth touch. Thinner, but the bag is tough, durable equivalent to traditional nylon bag. Compared to the price of nylon bags sold in the market, bags of self-destruction cost two times higher.
However, for researchers or people interested in plastic products, this biodegradable bag is not "divine", can be completely decomposed, not toxic and environmentally friendly. many people are thinking.
Differences between normal nylon bags and biodegradable plastic bags are on the market today
Talking about this issue, Truc Thanh, head of the Green Soul Club (a community of learning and practicing using resources effectively and improving the quality of life) shared: made of organic decomposing material is still not popular, most of the packaging used are made of full or partial plastic.
There are many types of nylon bags available on the market
Traditional nylon bag on the market is composed entirely of plastic particles with the product color, creating toughness, flexibility ....
Biodegradable nylon bags, which are sold in the market, contain about 40 to 50% more of the other ingredients, such as biodegradable additives, or some natural ingredients such as corn flour cassava, wheat flour.
Some natural ingredients such as cassava flour, corn flour, wheat flour ... are used as raw materials to produce biodegradable bags. Illustration
Thus, although plastic is less than ordinary plastic bags, the nature of biodegradable plastic bags is still plastic bags, which are added with additives to speed up the decay process.
This is the type of trash bag sold in supermarkets
When using biodegradable biodegradable plastic bags, many people think that this bag can decompose in the environment. However, this type of bag can not easily break down like leaves, wood items .... Decomposition bags must have appropriate conditions, ensuring a certain temperature, light, moisture, suitable for each new decay. According to information from the manufacturers, this bag can decay for 6 months to 2 years, or longer, depending on environmental conditions.
Read the ingredients carefully to find the right bag
In addition, to serve the needs of self-decomposed bags of consumers, many manufacturers have self-labeled the bag for the benefit. If you still choose to buy plastic bags, you should carefully read the ingredients of the bags.
In addition, it is possible to determine whether the biodegradable bags are toxic by burning. If the product is flammable, do not fumigate, limited toxicity. If the burning of the bag hard to smoke, smoke, strange smell, burn ... that is the bag is toxic.
Do you know?
According to incomplete statistics, every Vietnamese household usually uses 5 to 7 nylon bags per day, including large bags, small bags and micro bags. Millions of nylon bags are used and disposed of in the environment. daily school.
The decomposition of a nylon bag can last from 500 to 1,000 years without the exposure of sunlight.
Existence of nylon bags in the environment will cause serious damage to the soil and water, as the nylon bags in the soil will alter the physical properties of the soil, causing soil erosion, causing the soil to lose water and nutrients. Preventing oxygen from crossing the soil affects the growth of plants.
If nylon bags are thrown into ponds, lakes and rivers will clog sewers, ditches, canals, drainage and waterlogging, leading to the generation of more pathogenic bacteria.
Surprisingly, the soil and water environment polluted by plastic bags will directly and indirectly affect human health. Colorless plastic bags containing metals such as lead, cadmium, if processed food will harm human health.
