METAL RECYCLING

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!

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.

COPPER IS A GOOD MATERIAL TO RECYCLE

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.

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.

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

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.

Aluminium

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.

Know the Rubber Floors

Know the rubber floors that have appeared on the market as a novel solution to outdoor and indoor flooring. The technological advances are allowing more and more companies to dare with the development of new pavements that allow us to enjoy a healthy environment while at the same time pleasing to the eye and with easy maintenance. Rubber Flooring Singapore are one of the latest additions to the catalogue of companies responsible for manufacturing floorings thanks to its versatility, ease of assembly and respect for the environment. Do not wait any longer and discover all the information you need to know about rubber flooring singapore.

Made with rubber

Rubber flooring singapore are manufactured with a component called rubber. Rubber is an elastic element with a chemical composition that derives from the sap of various plants but can also be synthesized artificially. Natural rubber is obtained from trees or plants that are generally produced in South America or West Africa, however, today, most of the rubber flooring singapore is obtained synthetically without the need to remove trees from the environment. For the production of this material, large companies have plantations of overwhelming dimensions that are located, especially in China, Mexico, Vietnam and Brazil.

 

Rubber has been used in Central and South America even before the Spaniards discovered this part of the world. The natives used the sap of the trees for the elaboration of vase and sheets that protected elements against the water. Shoes or handles for tools were other uses adopted by these early civilizations. Once the Spaniards returned to the Iberian Peninsula with all materials and objects from America, rubber was used, in the first instance, as an element to eliminate the writing done with pencil on paper (even today we still use rubber as material to erase the mistakes made). It was not until World War I that the possibility of starting to develop synthetic rubber was discovered. To achieve that this material reaches the use that today makes it one of the main materials of the industry, a discovery by mistake must have taken place: vulcanization. Today, the most common use of this product for all of us is found on the wheels of the cars we use every day.

Rubber flooring singapore and other elements

 

As we have commented, probably the most common use for all of us of this material lies in the manufacture of wheels for automobiles. However, their uses are different and very varied. Thanks to its hydrophobic nature, rubber is used in the manufacture of elements that are used in protection against water as insulators or waterproofs. Another feature is that it is insulating both temperature and electricity, which also makes it a perfect material for real estate development. All these characteristics were discovered during the 19th century and, since then, we have found many garments that in one way or another use rubber flooring singapore for the protection of their users.

Rubber flooring singapore: characteristics

One of the main reasons why rubber flooring singapore have been chosen as one of the solutions for exterior pavements is their recycling capacity. That is to say, the rubber can be recycled in a relatively simple way and a material with the same characteristics as the original material is obtained without the need to continue consuming.

The most common places where we can find rubber floors are: schools, nurseries, gyms, swimming pools, … although every day more customers are daring to install this type of flooring in their terraces and gardens. The use inside the house is less common, however, thanks to its versatility, its comfort and its quilted surface, there are already several houses that install this pavement in one of the rooms to have a play area or a room for a small child and, in this way, protect the child from possible falls inside the house.

The rubber flooring singapore thicknesses range from 10 millimetres to 80 millimetres and we usually find them commercialized in large rolls of rubber or in tiles of different sizes. In addition to its longevity, which allows it to be a very durable pavement, the artificial composition of its elements allow the rubber floor to obtain a wide variety of solutions and designs that adapt perfectly to the place where they will be installed. The main characteristics of rubber flooring singapore floors are their durability, their flexibility, their safety, their comfort and their resistance. A rubber flooring singapore installed on a first floor will also allow an almost total acoustic insulation against impact noise, thus having a space located on the lower floor without any noise.

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.
