Promote "aluminum foil lunch boxes" to deal with "white pollution"
In my country, the "silver box" of "aluminum foil lunch boxes" is still a little unfamiliar to ordinary people, and plastic lunch boxes are still commonly used in the market. Relevant data show that almost 90% of the disposable lunch boxes used in the Shanghai market are polystyrene plastic lunch boxes. This type of plastic lunch box not only harms human health, but also causes great pollution to the environment.
The physical properties of plastic lunch boxes have obvious disadvantages when used. When people use disposable foam plastic tableware to hold hot food or boiling water with a temperature exceeding 65 degrees Celsius, the toxic substances contained in this tableware are easy to penetrate into the food. If the concentration of this harmful substance exceeds the standard, the toxicity will be greater. Foreign research results show that long-term absorption of chemicals in disposable foam tableware by the human body will cause damage to the liver and kidneys. In addition to causing harm to the human body, this "white pollution" also causes great damage to the environment. Waste plastic lunch boxes discarded in the environment not only affect the city appearance and natural landscape, but also pose a "potential hazard" to the ecological environment because they are difficult to degrade.
The relevant national and local departments have successively issued relevant policies and regulations to prohibit the use of disposable foam plastic tableware. Unfortunately, these unqualified tableware are still "prevalent" on people's tables. Despite the repeated warnings from the state, they have only been "transferred from ban to sale" and have not been fully and effectively curbed.
So, what material lunch boxes can be used to replace disposable foam plastic tableware? The product is light in weight, meets national food hygiene standards, is easy to recycle, does not produce harmful substances during the processing process, and does not pollute renewable resources... These advantages make "aluminum foil lunch boxes" the first choice to replace plastic lunch boxes. In addition, the most important feature of "aluminum foil lunch boxes" is that the recycling rate is high, which has a very positive significance for saving resources and reducing environmental pollution.
"Recycling" is a valuable feature of "aluminum". It is reported that aluminum can be recycled up to 25 times, and its service life is as long as 200 to 300 years. In addition, the production of recycled aluminum can save a lot of energy. Each ton of recycled aluminum produced only accounts for 5% of the energy used to produce each ton of electrolytic aluminum. At the same time, carbon dioxide emissions are reduced by 91% compared with the production of primary aluminum using hydropower, and by more than 97% compared with the production of primary aluminum using fuel power generation. In addition, compared with the geological changes caused by "white pollution", aluminum lunch boxes can be weathered in two to three years when placed in the soil, and will not cause lasting damage to the land or implanted changes in its properties.
