Aluminium fabricated parts boast an exceptional ability to undergo efficient recycling processes post-use. This characteristic stems from aluminium’s innate property of being endlessly recyclable without compromising its structural integrity or quality.
After serving their intended purpose, aluminium fabricated parts can be recycled through a straightforward process involving melting the material to its original state. This process, commonly known as remelting, allows the recycled aluminium to be reshaped and repurposed for a wide array of applications across industries.
The recycling of aluminium fabricated parts significantly contributes to resource conservation and environmental sustainability. It requires considerably less energy compared to primary aluminium production from raw bauxite ore.
Recycling aluminium consumes only about 5% of the energy needed for its initial extraction and processing, leading to a substantial reduction in greenhouse gas emissions. By reusing recycled aluminium in various manufacturing processes, the recycling industry plays a pivotal role in reducing energy consumption and minimising environmental impact, aligning with global sustainability objectives.

How Does Recycled Aluminium Work?
Aluminium, one of the world's most recyclable commodities, is a metal that is utilised in countless goods. Approximately 70% of all aluminium has been recycled at some point during its existence.
Aluminium is transformed into the desired shape by melting it in a furnace. A number of items are made by this process, which is called remelting. Being robust, long-lasting, pliable, impermeable, lightweight, and corrosion-resistant makes aluminium a more recyclable material than others. Recycled aluminium is a popular material for many uses because of its adaptability.
What Ways May Aluminium Be Reused?
Reusing aluminium allows for many recycling processes, often yielding the same result, since the metal retains its atomic structure during melting. Closing the loop is the name given to this process. Melting the metal is the standard method of recycling it. Take aluminium can recycling as an example of a process that recycles aluminium.
Aluminium Recycling: What Makes It Crucial?
Aluminium has infinite recycling potential since it can be melted and reshaped indefinitely without sacrificing quality. The amount of energy required to produce aluminium from raw sources is reduced by approximately 95% when the metal is recycled.
In comparison to the "primary" production process, recycling aluminium not only reduces energy consumption but also eliminates nearly all greenhouse gas emissions, by about 95%. The benefits of recycling become evident when you consider that 1 tonne of CO₂ is comparable to driving a car 4,500 kilometres.
Recycling 1 tonne of aluminium avoids 9 tonnes of CO₂ emissions. In as little as sixty days, the beverage can you recycle today might be transformed into a brand-new can, filled, and then restocked. One can could be recycled six times in a year, which would save enough energy to produce 160 new cans.
How Can I Recycle Aluminium?
Collecting and sorting are the initial steps in recycling aluminium. Recycling of aluminium requires first sorting the two distinct forms of scrap metal: post-production scrap and post-consumer scrap.
Waste From The Production Process
Any extra aluminium that is produced or used in the making of aluminium goods up until they are sold to the end user The aluminium here is scrap from some extrusion or fabrication operation.
New scrap includes things like aluminium extrusions and offcuts. After the composition of this new scrap is determined, it may be safely recycled by aluminium smelters.
Tomago Aluminium receives 500 metric tonnes of Capral's post-production scrap annually for recycling.
Recycled Materials From Consumers
Any aluminium that has been utilised by the customer and then thrown away.
Some examples of ancient trash include used beverage cans, window frames, electrical wires, and engine heads from vintage cars. Because the composition of this old waste is often unknown and can be contaminated, aluminium smelters cannot safely accept it.
Bales made of sorted bulk aluminium scrap are more cost-effective to transport, store, and handle than individual pieces of scrap. Melting down scrap aluminium is done in a massive furnace called a smelter. A gas-fired rotary furnace is used to remove any coatings from the scrap aluminium before it is sent to the remelter. Recycled aluminium is made by moulding molten aluminium into a certain form.
Aluminium Remelting In The Area
Because Australian smelters have always had trouble securely remelting aluminium scrap, over 95% of the country's aluminium ends up being exported for recycling. Exports of aluminium from Australia increased by 25.13 percent in 2020, reaching 119,075 metric tonnes.
Tomago Aluminium, the largest aluminium smelter in Australia, and Capral Aluminium have just signed an agreement to remelt around 550 metric tonnes of output garbage every annum in response to this difficulty.
Tomago will receive production scrap from Capral's Penrith extrusion factory, melt it down, and utilise it in the production of new aluminium goods, such as billet. To our knowledge, this is Australia's first commercial scrap arrangement.
Advantages Of Utilising Recycled Aluminium
Both "Aluminium" and "aluminium" convey the same message: this ductile, non-magnetic metal is incredibly abundant and has a wide range of uses. With its low density, high strength-to-weight ratio, and corrosion resistance capabilities, aluminium stands out as one of the most common elements. It is the third most plentiful element by mass, behind silicon and oxygen. Also, did you know that aluminium can be recycled indefinitely?
Recycling aluminium entails remelting scrap metal in order to separate the metal from its other components. About three quarters of the world's total aluminium supply—nearly a billion tons—is currently in use.
Consider the part's performance before deciding on a material to fulfil your project's needs. It is well-known that a component's performance is heavily dependent on its material capabilities.
Reusing aluminium instead of buying new is a win-win for the environment and your bottom line because recycled aluminium maintains all of its mechanical and physical properties and can be used for the same applications as primary aluminium that is mined from bauxite ore.
Recycled Aluminium Keeps All The Physical And Performance Characteristics.
When you see the word "recycled" on an item, you might assume that its strength and performance have been compromised. Even if your recycled paper straw is helping marine turtles, it will get mushy in your drink in about 10 minutes. When it comes to recycled aluminium, the story is different.
Aluminium keeps its qualities forever and can be recycled endlessly. Recycling secondary aluminium allows most businesses to attain the same degree of performance, lightweight durability, strength, and corrosion resistance as virgin aluminium.
However, there are a few industries that absolutely must have virgin aluminum's qualities, such as aerospace. Recycled aluminium is a great die casting material because it keeps its strength and durability even when heated, has great thermal conductivity, and is very dimensionally stable even when used with thin walls.
Reusing aluminium Cans Saves Money
The extraction of aluminium from its ores is a laborious and wasteful procedure. The technique uses electrolysis to convert bauxite into pure aluminium; however it's energy and raw materials intensive with low returns. Around four kilogrammes of raw bauxite ore and 190–230 megajoules of energy are needed to produce one kilogramme of aluminium.
In contrast, the amount of energy required to recycle aluminium is just around 5% of that required to generate original aluminium. It is common practice in manufacturing to charge customers for the cost of raw materials. Using recycled aluminium in your component's production cuts the raw material and energy costs by as much as 95%, even after accounting for the costs of collection, separation, and recycling.
Reduce Your Influence On The Environment By Using Recycled Aluminium.
Using recycled aluminium has several positive effects on the environment, such as lowering emissions of carbon dioxide and other greenhouse gases as well as pollution from mine and shipping. The majority of the energy required for aluminium die casting goes into heating and remelting the metal. This is why doing the remelting in-house will save you more time, energy, and money.
Furthermore, large-scale aluminium recyclers have begun to melt aluminium scraps using renewable energy sources like hydroelectric, geothermal, solar, or nuclear power, which are more environmentally friendly.
Responsibility Of Corporations Towards Society
Companies have been under increasing pressure from concerned citizens around the world to reduce their impact on the environment and act responsibly in recent years.
The response from the manufacturing sector has been a proliferation of programmes aimed at improving the quality of life in both local communities and the environment. To accomplish this, it is easy to use recycled aluminium alloys in manufacturing.
For example, recycling aluminium helps market leaders like Apple meet their ambitious sustainability targets without sacrificing the legendary lightweight performance of their products.
Conclusion
Because aluminium is infinitely recyclable, it makes for excellent post-use recycling of created parts. Melting the material back to its original state enables it to be moulded and reused for different industries; this process is called remelting.
Since recycling aluminium uses less energy than producing aluminium from bauxite ore, it helps conserve resources and promotes environmental sustainability. Recycling aluminium reduces emissions of greenhouse gases since it requires only approximately 5% of the energy required for its initial mining and processing.
Worldwide, there is a robust recycling infrastructure that makes it easy to collect, classify, and process aluminium scrap, which in turn supports the recyclability of aluminium produced parts. Businesses, industries, and individuals are motivated to participate actively in recycling projects by the high scrap value of aluminium, which serves as a substantial incentive.
The utilisation of recycled aluminium in numerous sectors, including transportation, building, aviation, and packaging, contributes to the growth of a circular economy and encourages a greener way of handling materials and manufacturing.
There are two types of metal scrap that are collected and sorted in this process: post-consumer scrap and post-production scrap. One of the most important parts of resource conservation and environmental sustainability is recycling aluminium since it cuts down on energy usage and gets rid of almost all greenhouse gas emissions.
Over ninety-five per cent of Australia's aluminium is sent abroad for recycling because smelters there have problems safely remelting scrap aluminium. An agreement to remelt approximately 550 metric tonnes of output waste each year has been inked between Tomago Aluminium and Capral Aluminium.
This scrap deal is the first of its kind in Australia. There is an endless supply of recycled aluminium, and it retains all of its mechanical and physical qualities throughout the recycling process. Because it keeps its physical and performance qualities, it is a cheaper alternative to buying new aluminium. Because recycling aluminium uses less energy and raw materials than mining it, it can help cut costs.
By reducing emissions of greenhouse gases and pollution from mines and shipping, recycling aluminium can further lessen environmental effects. Metal recycling companies on a grand scale, are increasingly turning to hydroelectric, geothermal, solar, and nuclear power to melt aluminium waste.
Recycling aluminium alloys helps companies achieve sustainability goals without compromising lightweight performance, which is important because corporations are under growing pressure to behave responsibly and lessen their environmental effect. As an example, Apple achieves sustainability goals without sacrificing lightweight performance by using recycled aluminium alloys.
