Based on the international environmental management standard ISO-14000, the tinplate with low pollution, recyclable and resource saving characteristics will have a broader development space in the future packaging applications：
In fact, tinplate, the main raw material in tin cans and containers, is environmentally harmless and can be naturally decomposed. When tins are in the environment, they can be naturally oxidized to return to the original state of iron oxide and return to nature. Therefore, the stacking of scrap iron cans can be decomposed by time and will not cause environmental pollution. At the same time, there is no need to cut down trees to make iron cans, which will not destroy the ecological balance.
The iron can itself has a characteristic that other packaging materials do not have, that is, it can be adsorbed by magnets. In this way, the iron cans can be separated from the waste by magnetic force of magnetic separator, and 80% of iron cans in garbage can be recovered easily by using this characteristic. The invention of environmental protection cover not only makes the use of iron cans more safe and hygienic, but also effectively reduces the amount of garbage, which has direct and obvious benefits for the recycling operation.
In aspect of removing other pollution residues on cans, chopper equipment’s been developed,which can effectively remove more than 98% pollutants and provide good quality scrap iron.United States also pointed out that existence of aluminum easy to open lid is conducive to scrap recycling,because it can reduce amount of hot metal used in steelmaking and reduce overall manufacturing cost.In terms of energy saving,report points out that using tinplate scrap to produce steel can save about 230m3 of natural gas per ton of scrap compared with production, so recycling process can reduce impact on global environment and energy, and conform to future product-trend.
