Containers currently in use include tin coated steel cans, aluminum cans, paper cans and plastic cans, and their recycling characteristics vary, but tin coating steel cans are more suitable for recycling than cans of other packaging materials.
1) Tin coated steel has low pollution
Tin coated steel, the main raw material of tin metal sheet boxes, is actually an environmentally harmless iron that can decompose naturally. Because the can body exists in the natural environment, it can be naturally oxidized and return to the original iron oxide state, so the stacking of the tank body can be decomposed over time, and will not remain and cause environmental pollution. There is no need to cut down trees when making tin coating steel cans, and tin coating steel will not destroy the ecological balance.
2) Tin coated steel has is recyclable
The tin coated steel has can itself has a characteristic that other packaging materials do not have, that is, tin coating steel can absorb magnets, so that the magnetic force can be used to separate the tin coating steel can from the waste by the magnetic separation device. Using this characteristic, tin coating steel can be easily recycled from the garbage. 80% tin cans. Moreover, 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 to the recycling operation.
3) Tin coated steel can save resources
In terms of removing other contamination residues on cans, a pulverizer has been developed, which can effectively remove more than 98% of contaminants and provide high-quality scrap iron. In addition, the United States also pointed out that the presence of aluminum easy-open lids is conducive to the reproduction of scrap iron, because it can reduce the amount of molten iron used in steelmaking and reduce the overall cost of steelmaking. In addition, in terms of energy saving, the report states that compared with iron ore production, the use of natural gas can be saved by 230m3 per ton of scrap iron, so the recycling and remanufacturing process of tin cans can reduce the impact on the global environment and energy, in line with future products trend. Therefore, the recycling process of iron cans can reduce the impact on the global environment and energy, in line with future product trends.
