Sustainable Aluminium
As a leading extruder and distributor in Australia’s downstream aluminium value chain, Alspec is dedicated to driving meaningful progress in sustainability and advancing the development of a more environmentally responsible built environment across the country.
Under its Sustainable Aluminium initiative, Alspec offers three distinct product ranges:
- – 20-13 by Alspec
- – GreenCore
- – Ultra GreenCore
Introducing 20-13 by Alspec
The process begins with post-production aluminium scrap generated by Alspec and Alspex. Rather than going to waste, this valuable material is collected, sorted, and transported to Rio Tinto’s Boyne Smelters Limited (BSL) in Gladstone, one of Australia’s largest aluminium smelting operations, further reducing carbon intensity.
At BSL, the scrap is remelted and transformed into high-quality aluminium billets with a minimum of 20% recycled content. These billets are then returned to Alspex, where they are extruded into new profiles. The finished extrusions are supplied to local fabricators and manufacturers to produce windows, doors, and other aluminium-based products—all made in Australia.
Alspec’s 20% recycled billet is ideal for projects where…
- Green Star by Green Building Council of Australia (GBCA), which encourage the use of recycled content and low-carbon materials
- Government tenders (local, state, and federal), which require low-emission materials with a preference for Australian-made content
- Apartments and Multi-Unit Developments where the promotion of sustainability as a value-add is a key consideration for Developers and Architects.
GreenCore®'s Low-Carbon Metrics: An Industry Benchmark
What is GreenCore?
‘Green’ signifies an all-encompassing embrace of environmentally conscious practices and state-of-the-art technologies. ‘Core’ refers to the billet, signalling that the material’s reduced carbon footprint is inherent, extending throughout its entire composition. We are proud to confirm that GreenCore® specifications are available across our comprehensive range of commercial window and door systems, providing customers with sustainable options that do not compromise on technical excellence.
The GreenCore® range boasts a carbon intensity of just 8kg CO2e per kg of aluminium. The metric, expressed as carbon dioxide equivalent (CO2e), is a universally recognised measure for assessing the global warming potential engendered during the production process. The Ultra GreenCore® range boasts a carbon intensity of just 4kg CO2e per kg of aluminium. This value sets a new industry standard, showcasing our commitment to advancing the frontiers of sustainable aluminium production.
