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.
