Based on the implementation of the international environmental management standard ISO-14000, tinplate coils and sheets cans with low pollution, recyclability and resource-saving characteristics will have wider development space for future packaging applications:
1.Tinplate coils and sheets have low pollution:
Tinplate products, the main raw material in tin cans, is actually environmentally harmless 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. The stacking can be decomposed by time, and will not cause residual environmental pollution. At the same time, it is not necessary to cut down trees to make tinplate products cans, which will not damage the ecological balance.
2.Electrical tinplate sheets are recyclable:
The tin can itself has a feature that other packaging materials do not have-electrical tinplate sheets can be adsorbed by magnets. In this way, the tinplate products can can be separated from the waste by magnetic force using a magnetic separator. Using this feature can easily achieve recycling In 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.
3.Tinplate products save resources:
In terms of removing other pollution residues on tinplate products 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 the recycling of scrap iron, 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 conservation, the report pointed out that compared to iron ore production, the use of tinplate coils and sheets scraps to produce steel can save about 230m3 of natural gas usage per ton of tinplate products scraps, so the recycling process of tinplate coils and sheets cans can reduce the global environment. With the impact of energy, in line with future product trends.
