Tin boxes themselves have a feature that other packaging materials don’t have—the ability to be adsorbed by magnets. In this way, a magnetic separator can be used to separate the tin boxes from the waste by magnetic force. This feature can easily achieve recycling. The effect of 80% tin boxes in the middle. The invention of the environmental protection cover not only makes the use of tin boxes safer and more hygienic, but also effectively reduces the amount of garbage, which has a direct and obvious benefit to the recycling operation.
In terms of removing other contaminated residues on tin boxes, shredder equipment has been developed, which can effectively remove more than 98% of contaminants and provide good quality scrap iron. In addition, the United States also pointed out that the existence of aluminum easy-opening lids is beneficial to scrap iron remanufacturing 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 with iron ore production, the use of tinplate scraps to produce steel can save about 230m3 of natural gas per ton of scrap iron scraps. Therefore, the recycling process of tin boxes can reduce the impact on the global environment. And the impact of energy, in line with future product trends.
