Metal Recycling: What It Is And How To Do It

Metals are essential, versatile and can be used in a variety of ways. This material can be used for industrial purposes, such as the manufacture of automobiles, trucks, ships, airplanes and railways. Metals can also be used to make household items, such as frying pans, cutlery and wrappers. A great advantage of singapore metal recycle is that it can be carried out again and again without altering the properties of this material.

The most commonly recycled metals are aluminum and steel. Other metals, such as silver, bronze, copper and gold, are almost never discarded or recycled because of their value. For this reason they do not create accumulation problems as waste.




The metal recycling process
This process is similar to the ordinary recycling process . First, singapore metal recycle are separated according to their properties; That is why it is very important to have basic knowledge about metals, as it will help you to recycle correctly and contribute to a cleaner, greener environment. The metal recycling process works as follows:



1.- Collection

It is the first and most important step in the recycling of metals and consists solely of collecting all objects that are made of metal. For this step you must have containers specifically designed to contain metals and be able to organize them.

Some people and companies have created spaces for people to be encouraged to collect different types of metal and take them there in exchange for a payment. These spaces are called metal collection centers. Each metal has a different price depending on where you sell it.



2.- Selection
Once the metals are collected, the next step is the selection. This means that what is recyclable is separated from what is not. It is necessary to emphasize that the quality of the recycled metal is very important. Only a recycled product of good quality can be created if the source materials used during the recycling process are of good quality, that is why a strict quality control is carried out during the selection process.


3.- Processing
After the selection stage, the next step is to compact or crush the metal. All recycling materials go through this process using machines. This is done so that the material does not occupy so much space in the cellars.


4.- Crushing

After the metals are fully compacted, the crushing process follows. In this stage, the metals are destroyed in small pieces or leaves to allow them to continue being processed. Although the pieces are small, they have a large surface that can be melted using less energy than would be used if the pieces were larger. Usually, steel is converted into blocks, while aluminum is converted into metal sheets.


5.- Melt
The melting of the metals that will be recycled takes place in a large furnace. Each metal is taken to an oven specifically designed to melt each type of metal according to its properties. This particular process consumes a large amount of energy. However, the energy required to melt the metal is less than what is needed to create it from its source materials. The furnace is heated to the exact temperature required to melt a particular metal. This process can take a few minutes or several hours, depending on the size of the oven, the amount of singapore metal recycle to be melted and the temperature of the oven.



6.- Purification
When the previous step concludes, the purification process follows. The metal is purified from different techniques. The metal purification is carried out to ensure that the final product has no impurities and that it is of good quality. One of the methods of purification of some metals is electrolysis. Other metals are simply passed through large magnetic systems to remove garbage. Currently, there are other methods of purification depending on the metal that needs to be cleaned.

 


7.- Solidification of the metal
After the purification process, an automatic band carries the melted metal to a cooling chamber where its temperature decreases and solidifies. In this step the collected metal becomes a solid metal that can be used again. Some chemicals are also added to the melted metal to have more consistency and other properties. In this cooling stage, different sizes and shapes are also given to the metals.



8.- Transport of metal bars
Once the bars have been designed and manufactured, the final product is packaged based on its size and shape. In this way you are ready to transport yourself to the different factories or people who need it. After this, the recycling cycle starts again.

Scrap Processing

The processing of Scrap Metal Singapore can avoid the manufacture of metals from ore and is the basis of the metal processing procedure in Russia. The use of scrap metals for production purposes significantly reduces energy consumption, the use of natural resources. Stably high demand for metal has led to the fact that scrap metal singapore receiving points have become a popular link between the recycling companies and producers.

 

How are scrap metal processed?

To learn how to process scrap metal singapore, it is necessary to get acquainted with the technology of the metal receiving point.

Metal, unlike secondary glass, paper and other raw materials, can be used almost indefinitely, as it does not lose its technical properties. Secondary processing of scrap metal singapore is a valuable and technically complex process, involving several main stages:

Preparation of scrap metal singapore. Collection and export of metal for further use is made from personal households, enterprises, factories, factories.

Sorting. This stage involves the sorting of the material delivered to the collection point for recycling by categories and composition. First of all, the color scrap is separated from the black one, since it is impossible to start them in one melting process. The sorted raw materials are packaged and sent for recycling.

Melting of scrap metal singapore. The procedure is carried out in specialized furnaces at high temperatures. For each type of metal, its temperature regime is assumed.

Cooling. At the last stage, the molten raw material is formed into small bars or ingots, after which it cools down. Cooled bars are sent to the production of metal products.

Prices for metal recyclable materials depend on the purity of the metal, its quantity, size and market demand. Scrap metal singapore of non-ferrous metals is more expensive than black scrap metal singapore. The cost of scrap is reduced if additional processing is required or the metal has foreign impurities. Different companies buy the same kind of raw materials at different prices, since most of the costs for processing scrap metal is its delivery to the processing enterprise: the farther away the scrap is from it, the lower the cost.

 

Processing of ferrous metals

Processing of black scrap metal begins from sorting to:

  •        metal (shavings, household items);
  •        stainless steel;
  •        scrap of cast iron.

These metals can be found in production waste, in bridge structures, in construction, often found in household devices and mechanisms: car parts, electric kettles, and bathtubs. The main difference of ferrous metals lies in the magnetic characteristics and susceptibility to corrosion.

 

Processing of non-ferrous metals

Processing of non-ferrous scrap is a rather complicated process. The technology of processing color scrap is carried out for each metal separately. Among the non-ferrous metals, the most popular are their own or defective products from:

  •        aluminum (old dishes, gutters, cans for drinks);
  •        copper (water products, wires, roofing materials);
  •        lead (car batteries);
  •        bronze (monuments, fences);
  •        brass (keys, plumbing, door handles, radiators).

Batteries containing a lot of lead are most often treated. It can easily be recycled and successfully used for further purposes. The old equipment, household appliances and industrial waste are not just garbage, they can cost quite a lot of money. Our organization gives abandoned glands a new life. For color scrap we give a high price, just call us or leave a request.

RECYCLING OF ALUMINIUM CANS

In Brazil, Scrap Aluminium Singapore is a success. The country ranks first in the scrap aluminium singapore index, with 94.4% of the material being recycled (data from 2006).

For industries, scrap aluminium singapore has obvious advantages in energy savings. For those who struggle against the degradation of the environment, scrap aluminium singapore prevents this can from being thrown into the wild. Aluminum can take from 100 to 500 years to degrade completely. In addition, it is 100% recyclable, thus saving, the extraction of 700 thousand tons of bauxite. The problems of global warming are also mitigated with recycling, as the process emits only 5% of the carbon dioxide emitted in the production of primary aluminum.

The scrap aluminium singapore cans is divided into ten steps. Aluminum does not degrade during the process, and can be used for the same purpose, unlike plastic bottles that, after being recycled, cannot store food. Its residual value is high, nobler than that of other reusable materials, making it a source of income for its collectors. To get an idea of ​​this figure, scrap aluminium singapore cans are currently worth 33 times more than steel and 55 times more than glass bottles. From the production of the tin in the factory until its return to the recycling centers, the time is two months.

Step-by-step recycling of cans

PURCHASE

The consumer buys the aluminum cans in the supermarket.

CONSUMPTION

After being used, the empty can is taken to the collection points or sold to the scrapers, who earn about R $ 3.00 for each group of 75 cans.

COLLECTION

In these places, the packages are pressed with all their parts (body, lid and ring).

PRESSURE

At this stage, the cans are pressed again. This time, in large bales, as they are called the “packages” bulky and heavy, easy to be transported.

FOUNDRY

The cans are melted in special ovens for aluminum cans.

CASTING

Here, all the material is transported in ingots cast in the form of strips, suitable for transformation.

LAMINATION

The ingots undergo a plastic deformation process in which the material passes between rolls and turns into aluminum coils.

NEW CANS

Coils are used to make new cans.

FILLING

In the beverage factory, the cans go through a filling process to gain that traditional “hollow” shape that we know of.

CONSUMPTION

Afterwards, the cans are distributed once more to the points of sale, closing the cycle of scrap aluminium singapore.
