What is Recycled Aluminium?
Recycled aluminium refers to aluminium that has been processed and reused from various sources, such as scrap metal and post-consumer products, rather than being extracted from primary metal sources.
It plays a significant role in enhancing sustainability by reducing energy consumption, lowering carbon footprint, and minimising waste and landfill.
Definition
Recycled aluminium is what you get when old, discarded aluminium products are collected, processed and transformed back into new items. By taking advantage of the fact that it can be re-melted again without losing its value, we give this metal a fresh lease on life.
This process helps us utilise an abundant supply of used aluminium in creating various products for different sectors – from cans and foils to vehicle parts and building materials.
With approximately 35% of global market supplies coming from recycled sources, this system significantly reduces our reliance on extracting primary metals from ores. Thus, every time we opt for recycled aluminium products, we’re actively advancing sustainability by saving energy equivalent to powering the Netherlands for a year!

By re-melting used aluminium, we can recycle it again and again without any loss in quality or value. This significantly reduces the need for primary metal extraction, conserves resources, and minimises waste.
Approximately 35% of global aluminium products are already supplied by recycled sources. Recycling aluminium annually saves an astonishing amount of energy that is equivalent to powering the Netherlands for a whole year.
How is Aluminium Recycled?
Aluminium is recycled through a process that involves sorting and shredding the materials, followed by melting and purification, and finally casting and forming them into new products.
Sorting and Shredding
We sort and shred recycled aluminium to prepare it for the recycling process. This step involves separating different types of aluminium, such as cans, foil, or scrap metal. By sorting the aluminium, we ensure that each type is processed correctly and efficiently.
After sorting, we shred the aluminium into small pieces or flakes. This increases its surface area and makes it easier to melt down during the purification stage. Sorting and shredding are crucial steps in recycling aluminium as they help maximise its value and promote sustainability by reducing waste and energy consumption.
Melting and Purification
In the process of recycling aluminium, melting and purification play a crucial role. When we melt recycled aluminium, it is heated to a high temperature until it becomes molten metal.
This allows impurities and contaminants to separate from the aluminium, ensuring that it is purified before being reused. The melted aluminium is then cast into different forms or used as raw material for manufacturing new products.
By recycling aluminium through melting and purification, we can reduce the energy consumption required for primary metal extraction and contribute to a more sustainable future. Plus, with its infinitely recyclable nature, aluminium can be melted and purified multiple times without losing its value or quality.
Casting and Forming
Casting and forming are essential steps in the process of recycling aluminium. During casting, the molten recycled aluminium is poured into moulds to create various shapes and forms.
This allows manufacturers to produce a wide range of products, from beverage cans to car parts. Forming, on the other hand, involves shaping the casted aluminium using techniques like extrusion or rolling.
These processes give recycled aluminium its versatility and make it suitable for different applications in industries such as construction, transportation, and packaging. By efficiently utilising recycled aluminium through casting and forming, we can contribute to a more sustainable future by conserving resources and reducing waste.
The Benefits of Using Recycled Aluminium Products
Using recycled aluminium products brings numerous benefits. It reduces energy consumption, lowers carbon footprint, minimises waste and landfills, and even saves costs.
Reduced Energy Consumption
Recycling aluminium products not only helps protect the environment but also reduces energy consumption. When we recycle aluminium, we save a significant amount of electrical energy that would otherwise be used in ore production.
Recycling just one tonne of aluminium can save up to five tonnes of bauxite ore and 14,000 kWh of electricity – enough to power a household for over a year! By using recycled aluminium products, we can contribute to a more sustainable future by reducing our dependence on primary metal extraction and conserving precious energy resources.
Lower Carbon Footprint
Recycled aluminium products have a lower carbon footprint compared to those made from primary metal sources. When we recycle aluminium, it requires significantly less energy and produces fewer greenhouse gas emissions than the production of new aluminium from raw materials.
Recycling aluminium saves more than 90 million tonnes of CO2 emissions each year. By choosing recycled aluminium products, you are making a sustainable choice that helps combat climate change and reduce our impact on the environment.
Reduced Waste and Landfill
Recycling aluminium products plays a crucial role in reducing waste and landfill. When we recycle aluminium, we divert it from ending up in the trash and instead give it new life. This means less waste going to landfills, which helps conserve valuable space and reduces environmental pollution.
By choosing recycled aluminium products, we are actively participating in a sustainable way of living by minimising our impact on the planet. Additionally, recycling aluminium requires significantly less energy compared to producing it from primary sources, further reducing carbon emissions and preserving natural resources.
As a result, using recycled aluminium helps create a greener future for all of us. With every recycled aluminium product we purchase or use, we contribute to the ongoing efforts of waste reduction and landfill prevention. We embrace the circular economy concept where materials are continuously reused instead of being discarded after one use.
Remember that recycling just one tonne of aluminium saves several tonnes (around four) worth of raw materials needed for production. By incorporating more recycled aluminium into our everyday lives – whether through packaging or construction materials – we can make a significant difference in reducing waste and landfill accumulation.
Cost Savings
Using recycled aluminium products can provide significant cost savings. One of the main reasons for this is that recycling aluminium requires much less energy compared to producing it from raw materials.
Melting aluminium from scrap only consumes about 5% of the energy needed for ore production. This reduction in energy consumption translates to lower costs for manufacturers and ultimately leads to more affordable aluminium products for consumers.
Additionally, by using recycled aluminium, companies can also save on waste disposal fees and landfill space. Overall, choosing recycled aluminium not only benefits the environment but also offers substantial cost savings.
