What is the Process of Recycling The Metal?

Metal is a widely used product in our day to day life. We can find it in packaging, wire, pots, cutlery, cans and various other items. Metals are elements of great durability and if they are discarded in nature, the decomposition time of the product can reach up to 500 years.

As regards their composition, scrap metal price singapore are divided into two groups: ferrous (iron and steel) and non-ferrous (aluminum, copper and their alloys which are brass and bronze, lead, nickel and zinc). There is a greater interest in the recycling of non-ferrous metals, due to the use value of scrap, but also the demand for scrap iron and steel is high.

They stand out as scrap metal price singapore: aluminum cans, steel cans, lids, fittings, pipes, frames and frame frames. Non-recyclables are: clips, staples, steel sponges, paint cans, fuel cans, and batteries.

There is a great advantage in the recycling of metals: in the normal phases of reduction of the ore in scrap metal price singapore there is a great consumption of energy, and for that process it is necessary a transport of high volume of ore and expensive facilities, destined to the large scale production. With recycling, this process is cheap.

How is recycling done?

  • The company that will carry out the recycling receives the material through collectors or other collection companies;
  • Already in the factory, the separation of the metal that arrives all mixed is made;
  • The already separated material is melted and transformed into new products;

Experts say there are four main metals that can be recycled: aluminum, iron, steel and copper. In Brazil, it is noteworthy that in aluminum, what is most used are cans, 98% of them are recycled. Approximately 65% ​​of the iron that the industry uses comes from recycling, as for steel this percentage drops to 30%.


The use of scrap metal in manufacturing reduces environmental impacts. In singapore metal recycle, the consumption of electric energy is 80% lower. The singapore metal recycle process also helps in the preservation of natural resources, as it avoids the extraction of new raw material, which also reduces CO2 emissions.

What can be recycled?

  • copper wires.
  • cartons made of tinplate (tin coated steel) such as oil cans, sour cream, tomato sauce, canned foods, etc.
  • aluminum foil and packaging such as beer, tea or soft drink cans, yogurt caps, coffee caps, etc.
  • cordless pans (this type of plastic is not recyclable) and trays.
  • wires, plates, hardware and any other product made of iron, stainless steel, aluminum, brass, copper or bronze.

What can not be recycled?

  • sponges and steel straws.
  • Aerosol cans.
  • cans of paints, varnishes and solvents.
  • Cans of toxic products like insecticides and pesticides.
  • Products made from heavy metals like some types of batteries.

How to prepare metal for recycling?

Singapore metal recycle items must be clean and can be compacted to decrease the volume. The can covers should be pressed inward to prevent accidents.

What to do with used batteries?

Batteries can not be disposed of in common waste. They need special treatment because they are composed of heavy metals (mercury, lead and cadmium) and toxic substances that can harm the environment and cause health problems. This material must be disposed of at the manufacturers’ voluntary service stations.

Dry batteries are an exception, and can be thrown into the common trash: (zinc-manganese or alkaline-manganese) used in devices such as cameras, radios, toys, among others; and portable batteries (lithium, lithium ion, zinc-air, nickel metal, hydride, button and miniature batteries and batteries) found in games, toys, portable power tools, computers, flashlights, photographic equipment, radios, sound, clocks, electronic organizers, shavers, measuring instruments, gauges and medical equipment.

Types of Bike Rims: Get to Know All Models

Do you know the different types of bike rim and, especially, the importance of it on your pedals? If the subject is still unclear, that’s fine. After all, there are several types of bike rim and for all models of bikes.

We can find, for example, bicycles with rim 29, bicycle cross with rim 20 or even a bicycle in aluminum with rim 26. Understand, however, that this is not a simple aesthetic decision, having meaning behind the types of rings offered.

Why are there different types of bike rims?

The bicycle wheels have basic and other differentiated configurations that allow a more assertive personalization in your choice for the ideal model. Even so, it is part of one of the cares when buying a bike.

For example, a cross-bike with bike rim 20 is more appropriate for one type of use, as a rim 20 for urban and daily circuits has another relevance for the rider. Hence the importance of assessing the size of the rim for its needs and objectives.

How to identify the ideal hoop size?

Let’s go to the basic concept: the size of the wheel is measured from all its diameter, already with the tire properly mounted. Thus, the size of the rim is idealized considering the use of the bike and the weight distributed on it.

For example: larger hoops are recommended for mountain bikes in steeper and more challenging areas. Even so, one of the main models for this is the mountain bike with bike rim 29. On the other hand, the leisure and daily traffic bikes in the city have, on average, the same size. With this, it remains to identify the use of this means of transport so versatile.

To help, we recommend reading the table below, which may make it easier to understand the types of hoops:

20 “(20”) hoop: often used on BMX or on foldable bikes;

24 “(24”) hoop: more suitable for bicycles used by teens;

26 “(26”) Hoop: Most Mountain Bikes feature this type of hoop as well as adult bikes;

Hoop with 29 inches (29 “): as already mentioned, quite used in mountain bikes with more challenging stretches.

In addition, there are bikes with smaller bike rim types. For children up to 5 years, models with 12 inches are indicated, for example. Just look at the proportion that the larger and larger hoops are suitable for challenging terrain, while the finer ones are suitable for speed bikes.

Structures for different types of rims

In addition to the features already mentioned, it is important to consider the most commonly used materials for making bicycle rims. Between them:

Structure: light alloy and lightning, the first one indicated for more speed and urban routes, while the second is more considered on rough terrain;

Material: reinforced steel and carbon fiber, the lightweight materials being more expensive – but more durable and resistant;

Brake bracket: beware of this, as bicycles with disc brakes need hoops that can support it.

With this, you should ensure more safety and good performance in your rides. Now, if you have the custom of taking your bike to all sides, be sure to check our tips to protect your bike against the action of the sea!


The mentality about the environment is changing. Every day there are more companies that make environmental management a basic component of their productive management. Today we will talk about why copper Scrap Wire Singapore is a good material for recycling

One of the most common actions that incorporate its management is recycling, a process that is combined with caring for the environment and reducing costs.

The mineral deposits can be exhausted, the raw material is not infinite, but thanks to recycling most metals are recycled in a high percentage.

We will hardly be left without copper, According to the Copper Development Association, the world’s known resources of the metal are estimated at 5.8 trillion pounds (15.26 x 10 kg approx.), Of which only 12% have been exploited as long story. Of this percentage, it is estimated that 80% still circulates around the world.

The more developed an economy is, the more copper it consumes. Therefore, since copper scrap wire singapore is of high durability, the need for more metal grows faster than the supply of waste.

On the other hand, today, most copper is used in the form of electric wires and cables, which require pure refined copper.

Domestic wires must have 99.9% one of the best metals for recycling purity, because the smallest contamination reduces their conductivity. Only 0.05% phosphorus or 0.08% iron reduce the transmission of electricity by one third.

Copper is 100% recyclable, does not lose any of its chemical or physical properties in the recycling process, can easily be incorporated into other production cycles and has few restrictions on its use.


Where is copper taken out for recycling?

The copper scrap wire singapore radiators of heat exchangers, thin wires, pipes, roofing sheets, electric cables…


What is recycled copper used for?

Copper for recycling is called copper scrap. It is classified and works in recycling plants as in the case of RECEMSA and by tons it is delivered to the foundries to use it as a raw material in their process

For the manufacture of pipes, roofing sheets, electronic chips, parts for motors and transformers, coins, … In short, for almost everything, you can see this many more detailed on our website in products: copper

Copper scrap wire singapore and its derivatives, either in its pure state or contained in a final product, can be recycled at all stages of the product’s life cycle.

The most significant rates of recycled copper use seem to be in Europe, with 45% (according to data from the International Copper Study Group).

On the other hand, the United States presents 33.3% (according to United States Geological Survey data).


How is copper recycled?

The processes to recycle copper vary according to the composition of the waste.

The pure copper waste can be melted directly. Its purity is checked by chemical analysis when it is still in a liquid state. Then it deoxidizes and leads to intermediate forms -such as ingots- to be used in other processes.

The residues containing oxides melt to form anodes that are then electro refined to obtain the desired level of purity.

In some alloys, such as brass and bronze, the copper residue melts and forms more alloys. In this case, it does not refine it again.

If the copper residue is mixed with other minerals, the cost-benefit ratio of the refining process is evaluated. In this way, if this ratio is very high -as in the case of the can and nickel that can only be separated by electro refining, the copper waste is destined for non-electrical purposes, that is, they do not require high levels of purity.


The economy of recycling

When promoting recycling, the reduction of productive costs is a key criterion. High quality waste costs 10% less than new refined copper cathodes

Copper and its alloys can be recycled relatively cheaply, with low energy consumption and minimal losses. Thus, if the alloys are made with recycled copper, the cost of the material can be significantly reduced.

But also, another basic criterion is the environmental one. Recycling not only helps to conserve raw material and reduce waste, but saves up to 75% of the energy used in primary copper production.

The copper residue, the metal that has already been used once, has the advantage of being present in metallic form in the medium. This avoids the energy waste of the process of extracting, transporting, melting and refining the material, since the energy needed to remelter and re-refines the waste is less.

Methods for Recycling Metal

Recycling metal is a simple step you can take to help the environment and reduce the cost of manufacturing items. Recycling facilities use several methods to Singapore Metal Recycle


it depending on the type of metal and the type of item. Recycling methods have allowed more singapore metal recycle material to be used in the manufacture of products.


Steel is one of the most common singapore metal recycle because it has industrial and commercial uses. Steel recycling methods take advantage of its magnetic properties to classify and process the metal. Since recycling facilities and machines can easily separate steel from other recyclable materials, it is not required to be sorted or prepared, making it cost-effective to singapore metal recycle. The process of recycling steel begins when it is added to cast iron and heated in an oven at 1,700 degrees Celsius. As a result, the metal cools and the machine turn it into large rolls. These rolls are then sent to the factories, to be used to produce new items with steel.


Many consumer products contain singapore metal recycle but the most found item is the aluminium can. The process of recycling aluminium begins by grinding cans or other items to remove paint and other layers that contain. The oven melts the crushed aluminium, then the metal is cooled in molds to give it shape and to be able to transport it easily. Recycling aluminium uses about 5 percent of the energy and materials that are used to do it originally. Aluminium foil follows a slightly different process since the aluminium alloy used in the paper is somewhat different.

Other Metals

Electronics such as computers, devices and telephones contain other types of metals that can be recycled. Metals in electronics require a more elaborate recycling process, since it can be difficult to extract from an article. Computers contain several types of valuable metals that are difficult to manufacture. The magnets in computers can contain nickel or cobalt and the circuit boards can contain gold, silver and platinum in addition to other common metals such as steel and aluminium. Recycling facilities use several methods to Singapore metal recycle found in electronics. The articles are crushed, then classified using magnets and electronic currents to separate the metals.
