Advantages and Disadvantages of Metal Recycling

Advantages

There are a number of metal recycling companies in Dubai. Recycling metals has numerous environmental and economic benefits.

• The products made from recycled metals require less energy compared to the ones made using raw materials. This reduces carbon emissions and conserves energy. According to the National Institute of Health, recycling aluminum uses 95 percent less energy while recycling steel saves 60 percent.(https://www.livestrong.com/article/132349-benefits-recycling-metal/)

• Less amount of metals need to  extracted through natural resources if we recycle them. This will help in reducing the landfills. Landfills affects the environment and reducing it will lead to a cleaner atmosphere and lessen the health concerns associated with waste.

• Recycling metals requires human resources and thus adds jobs to the economy.

• Production of primary  metals from the ore is expensive compared to recycling.

• Recycling metals adds to the research and scientific advancements being made for recyclable and biodegradable materials.

• The metals made from the primary ore release greater amounts of greenhouse gas emissions which are a threat to the environment. Recycling metals will reduce this. Since it uses less energy thereforeless fossil fuels are burnt.

• Ores which are a non renewable resource can be conserved by recycling metals.


Disadvantages

• The process of collecting and sorting the materials for recycling can be expensive and time consuming.

• Many of the recycled metals are impure and may not meet up to the demands of certain production standards.

Process of Recycling Copper

Copper has been in use by civilization since time immemorial and it is being recycled from ages. This non ferrous metal is the best conductor of electricity, second only to silver. Known for its high ductility and malleability and its conductive properties, copper is one of the most sought after metals.


The process for recycling copper involves following steps:

Step 1: Collection

Collecting copper scrap is the first step.  Copper has been the primary component in electrical wiring. It is a good conductor of electricity  and is present in cooking devices, air conditioners, electrical cables, heaters, appliances and furnaces. In a large automobile, as much as 100 pounds of copper can be found in its various components. It is also largely found in electronic devices. When you consider that a computer contains a one and a half kilogram of copper, it is easy to imagine the fortune of materials inside the devices that are thrown away.

Step 2: Sorting and Stripping/Granulation

The next step is to reclaim copper from  the copper scrap. The main machines used for recycling copper are copper peeling machines, stripping machine and granulators. For a single wire, copper stripping machine can be used. For wires with multiple strands and complicated knots, the copper granulator is used.

Step 3: Shredding and Melting

When the copper scrap  is  processed by copper granulator, peelers or strippers, the pure copper is separated  and transported for further processing. In case of using the wire stripping machine, it is not very convenient to transport the entire copper wire to the melting device and hence it is shredded further. At the smelter, the bales are fed into a furnace and heated until they become molten copper. The molten copper can then be poured into casters and moulds.

Step 4: Cooling and Fabrication

Once the molten copper has cooled and hardened, they are rolled out into sheets which form the basis of new materials.

What happens with recycled copper?

Ever wondered what happens to the scrap metals you deliver to a scrap dealer? Where it goes and what purpose copper scrap is used for? et us discuss the process of copper recycling in Dubai.

1. Inspection and sorting

Scrap copper is collected from various scrap dealers and delivered to a processing plant where it is processed into different grades, compositions and purity levels using automated machinery, testing equipment and quality control procedure. Rejected materials are returned back to the supplier, discarded in an environmental friendly manner or sent to other designated recycling plants.

2. Melting

Based on the Copper grade, it is melted and refined to achieve a higher quality of purity. Sometimes,  primary copper is added to enhance its quality or become suitable for certain industries.

3. Electrolytic Refinement

Electroplating of copper after dissolving it in a sulfuric acid bath ensures 99.98% purity of copper. This recovered pure copper can then be put to different uses.

4. Reintroduction into the market

The copper thus recycled can be used in electronics, plumbing and building construction, wiring in automobiles, etc. Copper, due to being biostatic, is useful in places with antimicrobial needs. Hospitals, fish farms, labs, etc, are increasingly using copper to keep microbes at bay.

Recycled copper may have minor impurities, but it is just as useful as primary copper, making copper recycling an important activity to be undertaken.

Environmental benefits of metal recycling

Metal recycling and scrap metal trading are has economical benefits yet often we see that many consumables from our domestic and industrial use are not recycled. Getting rid of metal recyclables to scrap metal recycling companies in Dubai and getting monetary benefit is one of the benefits of recycling apart from the obvious environmental benefits. Let us review the social-environmetal benefits of recycling.

1. Less waste

The more scrap metals are recycled, the less ends up in dumpsters and landfills, saving valuable earth space. It also prevents toxic chemicals from leaching into landfill over a period of time.

2. Reduced mining

The increasing demand for metals can be achieved through recycled metals which mean less dependence on mining for primary metals. Mining is an intense activity that takes a toll on the environment, and any initiative that limits it should be welcome.

3. Metal processing

The ore obtained from mining needs to be refined to extract metal that can be used for various applications. Metal processing involves use of many resources and chemicals that harms its surroundings. Recycling, in comparison, uses less energy, resources and is more environmental friendly.

4. Resource conservation

Recycling metals means less mining of natural resources. Thus recycling slows down the depletion of scarce natural resources such as ore, coal, water and energy which are required to mine primary metals. Thus recycled metals are a  valuable commodity in today’s world.

Recycling, to some people may feel like an act of simply getting rid of waste. However, in reality, recycled metals are a  precious commodity, so take your metal recyclables to a Dubai scrap yard today.

Know Your Metals: What Can You Recycle?

It is well established that scrap metal recycling is a great idea, for both commercial and residential institutions. Before you plunge into the beneficial world of scrap metals, it’s better to know your metals so you can get the best of this world.

The most sought out metals are:
  1. Brass - Door knobs, light fixtures, furniture accents, lamps, decorative utensils, keys, etc. have this material in abundance. So keep an eye out for this yellowish metal when you’re throwing away any of the above items.
  2. Copper - Used in electric fittings, wiring, copper utensils, pipes, etc. This reddish metal is fairly common too. Regular use and exposure to light can cause it to turn brownish-black, nothing a good cleaning can’t solve. Copper recycling in Dubai can be done if you manage to collect a substantial amount of copper to interest recycling centers.
  3. Aluminium - Aluminium scrap in Dubai is quite in demand. This silver grey metal can be found in utensils, soda cans, pipes, guttering, window frames, beds and many other places where a sturdy but lightweight metal is needed.
These are the 3 main metals that are corrosion resistant and a good deal for scrap recyclers. Apart from these, if you come across zinc, magnesium, tin, lead and nickel, you can take them to be scrapped too. The more the better!
