How to recycle steel

In terms of waste, iron seems to be one source of considerable intensity.

How to recycle steel

Not without reason, iron has become an inseparable part of people's lives. Various kinds of household appliances to the construction of a building using iron as part of the material.

What is Iron Waste?

Iron waste is a type of waste that comes from ferrous metal. Iron and metal waste is usually found from various sources. Not only from household scale disposal, iron waste is also often found as part of factory waste.

Factory waste in the form of iron is usually produced by industries that use iron as part of their production goods. Most factories are often not aware that the waste they produce is categorized as hazardous waste. If you don't know the type of iron waste, then this iron can be classified as a type of B3 waste.

What is B3 Waste?

B3 waste is a type of waste whose amount, nature or concentration can pollute or damage the environment. Iron waste is a type of solid waste that is difficult to decompose. In addition, iron also contains metals that are toxic to the environment.

Therefore, iron waste must receive special handling and not be disposed of carelessly. Iron and steel material is a type of product that can last a long time. Even though the shape is damaged and rusty, metal can still be recycled and reused into new items.

Here is a 5 How to recycle steel

1. Iron Waste Collection Process

Iron waste can be divided into several types. Among them are waste that comes from residual iron from industrial activities or waste in the form of cast iron. Scrap iron is iron that is old and usually rusts. This cast iron usually comes from building frames or used goods that have not been used for a long time.

But even so, do not take it lightly. Because both used and ex-factory iron can actually be used and reprocessed into new goods. So when you see scrap metal, don't throw it away. However, iron must be stored and collected together with similar wastes.

The first stage of processing factory iron waste is the collection stage. Thus, metal and iron wastes are collected together with similar wastes. Then the iron waste that has been collected will be stored in a special room that has been prepared.

2. Iron Sorting Process

After the iron and metal waste is collected, the next step is sorting. The iron waste produced by the factory may still be contaminated with other materials. Well, this sorting stage aims to separate metal materials from non-metallic materials that may stick to the iron.

The purpose of this sorting process is that the iron smelting process is not contaminated with other materials. So that the quality of the goods is higher because it is made of pure iron.

3. Metal Crushing Process

After going through the stages of collection and sorting, the iron waste will go through the next process, namely metal destruction. The destruction of this metal material is done to facilitate the smelting process.

The metal crushing process can be carried out in various ways, one of which is the iron grating process. In the crushing process, iron and metal are processed into small materials. So the iron becomes more soluble and melts when heated.

4. Metal Smelting Process

After the metal crushing process, the iron then reaches the smelting stage. In this process, the iron will be smelted in a large furnace. Then it is heated at high temperature until it melts. The process requires a very large level of heat for the iron to melt and melt. Well, the smelted iron will later be compacted, then processed into a new shape as needed.

5. Purification Process

The next method of processing iron waste is the purification stage. The purification process is carried out with the aim of ensuring product quality and ensuring that iron is free from contamination with other materials. The purification process is carried out by separating non-ferrous particles that may still be carried away during the smelting process.

These non-ferrous particles will make recycled products of poor quality if they are not separated. Therefore, the refining process is carried out very well. The goal is to produce quality recycled iron products.

6. Cooling Process

After going through the purification process, the next process is the cooling and solidification process. The cooling process aims to make the iron hard so that it can be easily reprocessed into various new goods.

In the process of cooling and solidification, iron will be formed into certain shapes. As formed into sheet iron, sheet iron, pipe-shaped iron and so on. After being processed and shaped like that, this iron will be easy to reprocess into goods that suit your needs.

7. Recycling Process

The last process of utilizing iron waste is the recycling process. This recycling process aims to process waste into new goods. Iron that has been formed into slabs or sheets is ready to be processed and made into new goods as needed.

People's need for goods made of iron is increasing from time to time. In addition to taking raw materials from nature in the form of iron ore. You can also use recycled iron collected from waste, both industrial waste and household waste.

Well, iron waste management does not only aim to help preserve the environment and reduce metal waste. The recycling process also helps reduce industrial raw materials. So there is no need to take it from nature, because it can take advantage of recycling as its raw material.

Those are some ways that can be done to treat factory iron waste. Waste processing can be done on a small scale either by means of a simple manual. You can also do it on a large scale using high-tech machines or using a fabricated system.

Easy Solution to Treat Iron Waste

In addition to processing waste independently, you can also entrust the waste processing process to third party services. Namely at companies that are specifically engaged in services regarding waste management.

The magnitude of the impact that can be caused by metal waste needs special attention from industry players. Especially for those who in the production process produce waste in the form of iron and metal.
