Building Sustainable Communities


The use of sustainable materials in modern Australian building construction is not negotiable. InfraBuild is redefining steel as a green building material and is helping companies everywhere improve the sustainability credentials of their projects.

InfraBuild is dedicated to conducting our business to global environmental, social and commercial standards. Our commitment to the environment includes optimising the eco-efficiency of our products through the product life-cycle.

We are committed to the role played by steel in the circular economy, including the promotion of the recovery, reuse and recycling of steel and other products.

GREENSTEEL™ and CN30


We produce low-carbon steel and manufactured products, using GREENSTEEL™ manufacturing approaches to lower our carbon footprint.

Through recycling scrap metal, and using our Electric Arc Furnaces (at Rooty Hill, in Sydney, and Laverton, in Melbourne), we reduce carbon emssions by a third compared to traditional steelmaking methods.

Recycling scrap metal reduces pollution, saves resources, reduces waste going to landfill and is an integral part our GREENSTEEL™ strategy, providing our businesses with a sustainable supply of feedstock for our electric arc furnaces to produce steel.

As a member of the GFG Alliance, we are committed to its carbon neutral by 2030 ambition (CN30) and using new and emerging technologies and manufacturing processes to further reduce our carbon footprint.

Supply Chain traceability and Modern Slavery


InfraBuild is an industry-recognised leader in the field and was one of the first listings in the Infrastructure Sustainability Council of Australia’s (ISCA) ISupply directory. The directory provides direct access to suppliers that can help a project or asset achieve sustainability.

We have also implemented a Supplier Standard (code of conduct) which specifically addresses our commitment to human rights, zero tolerance to human trafficking, child labour or the use of conflict minerals. To address Modern Slavery we have conducted a risk assessment to identify suppliers with a high risk to any potential modern slavery practices. Agreements now include specific clauses to modern slavery and have been put in place with high risk suppliers. This is outlined in our Modern Slavery Statement.

Sustainable Steel. Sustainable Communities

InfraBuild's holistic approach to sustainability, is documented in the GFG Alliance Sustainability Report Australia annual publication.

Environmental Product Declarations

InfraBuild’s Environmental Product Declarations (EPDs) are independently verified and are premier contributors to our holistic commitment to the environmentally sustainable manufacture and application of our products. Recognising our customers’ need and the increasing demand for standardisation and greater transparency around environmental performance, InfraBuild is proud to publish the sustainability credentials of our supply chain and products.

These updated EPDs supercede the previous ones published in 2016 and take steps to reflect the industry’s evolving understanding of sustainability. Recognising the increasing focus on the Circular Economy as a key aspect of sustainability, Material Circularity Indicator (MCI) metrics have been developed for all InfraBuild's products covered by EPDs. The inclusion of MCI data in the relaunched EPDs provides sustainability professionals with additional information and allows for benchmarking of InfraBuild processes as a more circular manufacturing model evolves throughout the business.



Who developed the InfraBuild, ARC and Liberty EPDs?

Thinkstep-anz were commissioned to develop the EPDs and associated MCI for the products with independent verification from start2see. Each EPD has been updated in line with the required 5-year validity, including updated hotspot data covering over 95% of all impacts.

How does the MCI work?

The MCI tracks material flows from virgin stock, to use and eventual reuse. In short, its focus is entirely on the materials going in and the waste coming out along each step of a product’s lifecycle. It also considers a product’s utility when making the calculation, which includes the intensity of use and intended lifespan. Finally, the MCI has a simple scale of 0–1, with 0.1 indicating a linear process and 1 indicating a fully circular one. A result of less than 0.1 indicates a linear product with lower-than-average utility.

What is the MCI score of InfraBuild product?

Reflecting our dedication to sustainability, InfraBuild products scored 0.824.This score indicates their extremely high recycled steel content as well as their recyclability potential at end of life.

InfraBuild's EPDs comply with the requirements of a valid EPD recognised in the Green Star Design Rating Tool (Green Building Council of Australia) and the IS® Rating Tool (Infrastructure Sustainability Council of Australia).

"Congratulations to InfraBuild on the release of a further six Environmental Product Declarations which transparently communicate the life cycle impact of these products. Infrabuild continue to take action that aligns with their organisational values and mission to drive nation-building infrastructure using local resources and more sustainable solutions."

“EPD Australasia is delighted to see InfraBuild updating and launching a revised set of six EPDs to the market, after releasing their original EPDs in November 2016. With sustainability a key metric in the consideration of construction and infrastructure space, InfraBuild’s EPDs cover both structural steel and reinforcing steels used in these projects. InfraBuild should also be congratulated for leading the way by including Material Circularity Indicator (MCI) metrics in their EPDs that allows metrics to be introduced into discussions on the Circular Economy methodology.”

Stephen Mitchell, Chair, EPD Australasia

"InfraBuild has been an early leader in transparency with their commitment to carbon neutrality by 2030, and is showing an ongoing commitment to sustainability with their updated environmental product declarations. The new suite of EPDs clearly verify the sustainable solutions that InfraBuild are offering to the market."
