Compared with plastic boxes, the higher cost of aluminum foil lunch boxes is one of the important reasons. It is understood that the cost of polystyrene lunch boxes is only a few cents, while a 20-gram aluminum foil lunch box sells for 0.80 yuan. Even after deducting the recycling price of 0.22 yuan each, the actual price of each aluminum foil lunch box is as high as 0.58 yuan, dozens of times more than a polystyrene lunch box. We believe that what is calculated here is only an economic account, and it is a very incomplete economic account. We must not use poisonous things because they are cheap and cause ourselves a chronic suicide. Another important reason why we promote the use of aluminum foil lunch boxes is the "recyclable" characteristics of aluminum.
The characteristic of "recyclable application" is mainly reflected in the high recycling rate of aluminum foil lunch boxes, which has a very positive significance for saving resources and reducing environmental pollution. "Recyclable application" is an important characteristic of aluminum. Generally, aluminum can be recycled up to twenty-five times, with a service life of two to three hundred years, and the production of recycled aluminum can save a lot of energy consumption. The production of one ton of electrolytic aluminum requires an average of 14,500 kilowatt hours of electricity, and the production of one ton of recycled aluminum only accounts for 5% of the energy used to produce one ton of electrolytic aluminum. At the same time, the carbon dioxide emissions are more than 90% lower than the production of electrolytic aluminum.
In addition, compared with the geological changes caused by "white pollution", aluminum lunch boxes can weather after being placed in the soil for two to three years, and will not cause sustained damage or implanted property changes to the land. In fact, regarding the cost of use, the current high price situation can also be changed through supporting processing equipment. If the production scale reaches more than 10,000 pieces a day, rent, manpower and energy consumption can be reduced, which can basically absorb part of the higher costs. Since the recycling of aluminum foil lunch boxes can also enjoy government subsidies, the overall cost is not higher than that of plastic lunch boxes. Therefore, the key is still a matter of concept. If we start from the perspective of "cherishing life", it would be much easier to promote the use of aluminum foil lunch boxes.
