Capral is excited to introduce LocAl®, a lower-carbon primary aluminium option available across Capral’s locally manufactured extruded aluminium products. Providing Australian manufacturers access to cleaner, greener, more sustainable aluminium for their projects.
The LocAl® offer includes two lower carbon aluminium options: LocAl® Green with carbon emissions of 8kg CO2e/kg Al* and LocAl® Super Green at 4kg CO2e/kg Al* – amongst the lowest carbon aluminium available globally.
In 2022 Capral committed to reaching Net Zero emissions by 2050, a significant step change, driving rapid innovation and cultural evolution throughout the business, most notably within procurement and operations. The introduction of LocAl® demonstrates a deliberate shift in Capral’s procurement strategy for primary aluminium billet.
Luke Hawkins, General Manager of Supply & Industrial Solutions, comments: “In 2022, 22% of the primary aluminium billet Capral uses in its eight local extrusion presses has a carbon content lower than eight kilograms CO2e per kilogram of aluminium. Approximately 300 tonnes have a certified carbon content lower than 4 kilograms of CO2e per kilogram of aluminium. This is a strategic change for Capral, driven by our desire to make lower Carbon aluminium accessible to Australian manufacturers. The market is looking for this product, and as Australia’s largest extruder of aluminium, we must make it available.”
Aluminium is often touted as the “Sustainable metal”, its versatility and recyclability earning it this reputation. However, there are significant variations in the carbon emissions generated by smelters during the production of primary aluminium – one might argue that some aluminium is considerably more sustainable than others.
The main contribution to the carbon emissions of aluminium comes from the electrolysis process used in aluminium smelting. Around 60% of the aluminium sector’s GHG emissions are from the production of electricity consumed during the aluminium smelting process.
A salient fact that may surprise some is that combined, the four Aluminium Smelters producing primary aluminium within Australia consume approximately 10% of the national energy grid.
The carbon emissions in primary aluminium production range from under 4kg CO2e/kg Al to over 20kg CO2e/kg Al, largely dependent upon the energy sources used. The current global average carbon emission for primary aluminium is approximately 16.8 kg CO2e/kg Al.*
