Existing containers include iron cans, aluminum cans, paper, and plastic containers. These containers have different recycling characteristics, but the use of iron cans is superior to other packaging materials.
Based on the implementation of the international environmental management standard ISO-14000, tinplate cans with low pollution, recyclability, and resource-saving characteristics will have wider development space for future packaging applications:
Tinplate, the main raw material in tin cans, is actually environmentally friendly and can be naturally decomposed, because when tin cans exist in the environment, they can naturally oxidize and return to the original iron oxide state, returning to nature, so waste iron cans The stacking can be decomposed by time, and will not cause environmental pollution due to residue. At the same time, it is not necessary to cut down trees to make iron cans, which will not damage the ecological balance.
The tin can itself has a feature that other packaging materials do not have-it can be adsorbed by magnets. In this way, the iron can can be separated from the waste by magnetic force using a magnetic separator. Using this feature, it is easy to achieve recycling. The effect of 80% tin can. The invention of the environmental protection cover not only makes the use of iron cans safer and more hygienic, but also effectively reduces the amount of garbage, which has direct and obvious benefits for recycling operations.
In terms of removing other pollution residues on iron cans, shredder equipment has been developed, which can effectively remove more than 98% of pollutants and provide good quality iron scraps. In addition, the United States also pointed out that the existence of aluminum easy to open the lid is conducive to scrap iron recycling, because it can reduce the amount of Hot Metal used in steelmaking and reduce the overall cost of steel manufacturing. In addition, in terms of energy saving, the report pointed out that compared to iron ore production, the use of tinplate scraps to produce steel can save about 230m3 of natural gas usage per ton of scrap iron scraps, so the recycling process of iron cans can reduce the global environment. With the impact of energy, in line with future product trends.
