"A Sydney based steel company is testing a “sustainable” steel product made
from 100 per cent scrap that it hopes can deliver major savings in materials
and embodied emissions for wind turbines installed in Australia.
The testing is being conducted by InfraBuild, which has its origins from the
start of the Newcastle steelworks in 1915 and which was bought in 2017 by
Sanjiv Gupta’s GFG Alliance, the former owner of the Whyalla Steelworks.
Infrabuild says the new product, known as Sense 600, is made in the company’s
Electric Arc Furnaces, which boast lower emissions compared to the conventional
Blast Furnace/Basic Oxygen Furnace (BF-BOF) method.
The product is also able to deliver the equivalent load capacity while using up
to 16.7 per cent less raw materials, and 39 per cent less embodied carbon when
compared to the company’s own standard Grade 500N reinforcing bar.
Australia is estimated to need around 25,000 new wind towers to meet its 2030
target of 82 per cent renewables.
The new testing of Sense 600 is designed to assess its suitability for use in
wind turbine tower bases, and it is also looking at opportunities in the
recycling of old wind farms.
Amir Hassanieh, InfraBuild’s technical engineering manager for innovation, is
leading the new research and says that his team has spent the last 18 months
working with Monash University to explore the fatigue performance of the Sense
600 range.
“The findings so far support the use of Sense 600 in wind farm applications
where reinforcing steel is subject to frequent stress cycles far in excess of
those in typical construction projects,” Amir said.
“Using our more sustainable steel products in renewable projects is a natural
next step for a company which is focused on value adding to its steel products
and its decarbonisation efforts.”
The first phase of this new testing is expected to be completed in the first
quarter of 2026."
