Is scrap metal hazardous waste

There are various types of household waste piled up like mountains, among which there is a type of waste called scrap metal.

When dealing with garbage, various problems are always encountered, which can cause difficulties. However, resources are limited after all. Nowadays, the world has begun to study and practice the recycling and reuse of resources. Among them, scrap metal is the key to recycling and reuse in order to create greater benefits.

At the same time, the question arises whether the scrap metal in the vast amount of household waste is hazardous waste? If it is hazardous waste, wouldn't it cause great trouble for the recycling of scrap metal? And some people suspect that even if scrap metal recycling is completed, it still carries a large amount of harmful substances that are not suitable and can be reused.

In fact, it is relatively simple to recycle and regenerate scrap metal. There are not many harmful substances. If good classification planning can be carried out, many scrap metals can be directly recycled and reused! In this way, while saving metal resources, it can also save costs and increase profits, killing two birds with one stone.

For example, in China, producing and utilizing 1 ton of recycled aluminum can save about 87.5% of costs compared to producing 1 ton of primary aluminum. To do a simple math, compared to directly producing primary aluminum, the same tonnage of recycled aluminum only requires 12.5% of the cost of primary aluminum, and the process is relatively simple. The key point is that these scrap metals are extracted from household waste, and harmful substances will naturally be relatively less.

In urban waste, industrial waste, and some scraps, there will be scrap metal, and most of it is in a mixed state. If magnetic separation is used, it can be easily separated by first selecting. After selection, the scrap metal is crushed, separated, and then integrated.

Of course, in industry, waste can also be divided into different metal categories to make these metals more valuable for utilization.

During the recycling process, scrap metal is collected using machines without any chemical treatment, whether it is screening or grading operations, so no harmful substances are produced.

In summary, the process of recycling and reusing scrap metal is quite simple, and it is obvious that a word about hazardous waste is just false information.
