Australia: Cement Australia has received a US$34.4m federal grant for a kiln upgrade to its Railton cement plant in Tasmania. The upgrade will allow the plant to raise its alternative fuels substitution rate. The project is funded by the government’s Powering the Regions initiative, with total investments valued at US$215m.
Australian Minister for Climate Change and Energy Chris Bowen said “This US$215m investment in Australia’s hard-to-abate manufacturing and mining facilities is about securing the future of high-quality, low-emissions products made right here. Northern Tasmania, Central Queensland and Western Australia have been industrial powerhouses for generations, and the government is ensuring that continues. As global markets change rapidly, we’re supporting Australian industry to not only survive but thrive with our world-class products that support regional jobs across the country.”
Australia: Cement Australia has signed a new three-year rail haulage agreement with Pacific National to transport shipping containers of cement, sand, fly ash, slag and lime. This will also includes the interstate and inter-city transport of cement and supplementary cementitious materials between large cities and throughout North Queensland. Cement Australia and Pacific National have a partnership that dates back over five years.
Pacific National is Australia’s largest private rail freight operator.
Australia: Cement Australia has commemorated the 100th anniversary of the start of operations at its Railton cement plant in Tasmania with a centenary dinner.
Production manager Garry Bissett said "When it opened up in 1923, they built the small kiln, and it was only capable of cement production of 25,000t/yr; now we're producing 1.4Mt/yr." He added that the workforce has fallen to less than half of its original size of 300 people, to 140. Bissett concluded "We're doing some major work, with a lot of capital upgrades in the near future."
Cornwall Coal to plans new coal mine in Tasmania
05 January 2023Australia: The Australian government’s Department of Climate Change is receiving public comments on Cement Australia subsidiary Cornwall Coal’s plans to open a new coal mine in Tasmania’s Fingal Valley, near St Mary’s. Local press has reported that the proposed site will operate across three open pits, with a total area of 26ha. The mine will replace the company’s nearby Cullenswood coal mine when it runs out of coal later in 2023, and will operate until 2026 or 2027. Cornwall Coal’s Tasmanian operations currently supply coal for Cement Australia’s Railton cement plant, as well as other local industrial sites.
Under Cornwall Coal’s proposals, the company will build travel culverts for local wildlife, and assist in relocating animals currently occupying the site. Tasmanian devils and two species of quoll – all endangered – live on the land in question.
Mick Tucker, head of Break O’Day Municipality Council, said that the municipality currently depends on Cornwall Coal’s operations for 60 – 80 jobs. He said that the company’s plans have strong support in the local community.
Slashing cement's CO2 emissions Down Under
02 November 2022In Australia and New Zealand, four producers operate a total of six integrated cement plants, with another 13 grinding plants situated in Australia. This relatively small regional cement industry has been on a decades-long trajectory towards ever-greater sustainability – hastened by some notable developments in recent weeks.
Oceania is among the regions most exposed to the impacts of climate change. In Australia, which ranked 16th on the GermanWatch Global Climate Risk Index 2021, destructive changes are already playing out in diverse ways.1 Boral reported 'significant disruption' to its operations in New South Wales and southeast Queensland due to wet weather earlier in 2022. This time, the operational impact was US$17.1m; in future, such events are expected to come more often and at a higher cost.
Both the Australian cement industry and the sole New Zealand cement producer, Golden Bay Cement, have strategies aimed at restricting climate change to below the 2° scenario. Golden Bay Cement, which reduced its total CO2 emissions by 12% over the four-year period between its 2018 and 2022 financial years, aims to achieve a 30% reduction by 2030 from the same baseline. The Australian Cement Industry Federation (CIF)'s 2050 net zero cement and concrete production roadmap consists of the following pathways: alternative cements – 7%; green hydrogen and alternative fuels substitution – 6%; carbon capture – 33%; renewable energy, transport and construction innovations – 35% and alternative concretes – 13%, with the remaining 6% accounted for by the recarbonation of set concrete.
Australia produces 5.2Mt/yr of clinker, with specific CO2 emissions of 791kg/t of clinker, 4% below the global average of 824kg/t.2 Calcination generates 55% of cement’s CO2 emissions in the country, and fuel combustion 26%. Of the remainder, electricity (comprising 21% renewables) accounted for 12%, and distribution 7%. Australian cement production has a clinker factor of 84%, which the industry aims to reduce to 70% by 2030 and 60% by 2050. In New Zealand, Golden Bay Cement's main cement, EverSure general-purpose cement, generates CO2 at 732kg/t of product.3 It has a clinker factor of 91%, and also contains 4% gypsum and 5% added limestone.
Alternative raw materials
Currently, Australian cement grinding mills process 3.3Mt/yr of fly ash and ground granulated blast furnace slag (GGBFS). In Southern Australia, Hallett Group plans to commission its upcoming US$13.4m Port Augusta slag cement grinding plant in 2023. The plant will use local GGBFS from refineries in nearby Port Pirie and Whyalla, and fly ash from the site of the former Port Augusta power plant, as well as being 100% renewably powered. Upon commissioning, the facility will eliminate regional CO2 emissions of 300,000t/yr, subsequently rising to 1Mt/yr following planned expansions. Elsewhere, an Australian importer holds an exclusive licencing agreement for UK-based Innovative Ash Solutions' novel air pollution control residue (APCR)-based supplementary cementitious material, an alternative to pulverised fly ash (PFA), while Australian Graphene producer First Graphene is involved in a UK project to develop reduced-CO2 graphene-enhanced cement.
Golden Bay Cement is investigating the introduction of New Zealand's abundant volcanic ash in its cement production.
Fuels and more
Alternative fuel (AF) substitution in Australian cement production surpassed 18% in 2020, and is set to rise to 30% by 2030 and 50% by 2050, or 60% including 10% green hydrogen. In its recent report on Australian cement industry decarbonisation, the German Cement Works Association (VDZ) noted the difficulty that Australia's cement plants face in competing against landfill sites for waste streams. It described current policy as inadequate to incentivise AF use.
Cement producer Adbri is among eight members of an all-Australian consortium currently building a green hydrogen plant at AGL Energy’s Torrens Island gas-fired power plant in South Australia.
Across the Tasman Sea, Golden Bay Cement expects to attain a 60% AF substitution rate through on-going developments in its use of waste tyres and construction wood waste at its Portland cement plant in Northland. The producer will launch its new EcoSure reduced-CO2 (699kg/t) general-purpose cement in November 2022. In developing EcoSure cement, it co-processed 80,000t of waste, including 3m waste tyres. The company says that this has helped in its efforts to manage its costs amid high coal prices.
Carbon capture
As the largest single contributor in Australia's cement decarbonisation pathway, carbon capture is now beginning to realise its potential. Boral and carbon capture specialist Calix are due to complete a feasibility study for a commercial-scale carbon capture pilot at the Berrima, New South Wales, cement plant in June 2023.
At Cement Australia's Gladstone, Queensland, cement plant, carbon capture is set to combine with green hydrocarbon production in a US$150m circular carbon methanol production facility supplied by Mitsubishi Gas Chemical Company. From its commissioning in mid-2028, the installation will use the Gladstone plant's captured CO2 emissions and locally sourced green hydrogen to produce 100,000t/yr of methanol.
More Australian cement plant carbon capture installations may be in the offing. Heidelberg Materials, joint parent company of Cement Australia, obtained an indefinite global licence to Calix's LEILAC technology on 28 October 2022. The Germany-based group said that the method offers effective capture with minimal operational impact.
Cement Australia said “The Gladstone region is the ideal location for growing a diverse green hydrogen sector, with abundant renewable energy sources, existing infrastructure, including port facilities, and a highly skilled workforce." It added "The green hydrogen economy is a priority for the Queensland government under the Queensland Hydrogen Industry Strategy.”
Logistics
Australian and New Zealand cement facilities' remoteness makes logistics an important area of CO2 emissions reduction. In Australia, cement production uses a 60:40 mix of Australian and imported clinker, while imported cement accounts for 5 – 10% of local cement sales of 11.7Mt/yr.
Fremantle Ports recently broke ground on construction of its US$35.1m Kwinana, Western Australia, clinker terminal. It will supply clinker to grinding plants in the state from its commissioning in 2024. Besides increasing the speed and safety of cement production, the state government said that the facility presents 'very significant environmental benefits.'
Conclusion
Antipodean cement production is undergoing a sustainability transformation, characterised by international collaboration and alliances across industries. The current structure of industrial and energy policy makes it an uphill journey, but for Australia and New Zealand's innovating cement industries, clear goals are in sight and ever nearer within reach.

Cement Australia partners with Mitsubishi Gas Chemical Company for green methanol trial at Gladstone cement plant
28 October 2022Australia: Cement Australia’s Gladstone cement plant in Queensland will host a study of methanol production from green hydrogen and captured CO2. Japan-based Mitsubishi Gas Chemical Company will supply its green methanol production technology, while hydrogen and oxygen feedstocks will be sourced locally. Cement Australia and Mitsubishi Gas Chemical Company will collaborate on commercialisation of their green methanol. Cement Australia said that carbon capture and its utilisation in value added products is a strategic pillar of the company’s decarbonisation roadmap.

Australia: The Queensland Supreme Court has ruled that Wagners must meet lower prices offered by a competitor in the market in its cement supply contract with Boral. Wagners suspended its supply of cement products to Boral for six months in early 2019 when Boral said it found cheaper cement from Cement Australia, according to the Australian newspaper. However, the court found that an October 2019 pricing notice for cheaper supplies from Cement Australia was ‘valid and effective’. Boral will continue buying cement from Wagners until 2031.
Cement supply spat in Australia
30 October 2019The Australian cement supply spat calmed down a little this week with the announcement that Wagners Holdings has agreed to resume the supply of cement products from its Pinkenba grinding plant in Brisbane to Boral. Legal proceedings are still on-going with a trial date set at the Supreme Court of Queensland in late November 2019.
The argument blew up publicly in March 2019, when Wagners said it had suspended its cement supply to Boral for six months. Wagners has a cement supply agreement with Boral whereby it supplies cement on an annual basis for a fixed price. However, Boral informed Wagners that it had found cheaper cement from a ‘long established’ supplier in South East Queensland. Local press speculated that this ‘long established’ supplier was Cement Australia, the joint venture between LafargeHolcim and HeidelbergCement. Wagners then had the choice to either match the lower price or suspend its supply. The disagreement took the legal route as the parties failed to reach an agreement. Wagner says that its cement supply agreement with Boral ‘remains binding on both parties’ until 2031.
Wagners later reported that it expected the suspension to cost it around US$7m in 2019. The deal with Boral constituted about 40% of its cement sales volumes. Its overall revenue grew year-on-year in its 2019 business year to the end of June 2019 but its cement sales volumes fell. Its earnings also fell. This was blamed on higher activity in lower margin areas such as contract haulage and fixed plant concrete, and delays in major infrastructure project work in South-East Queensland.
Boral, meanwhile, suffered from falling revenue and earnings from its Boral Australia subsidiary in its financial year to June 2019 due to a slowing construction market. Notably, its cement sales revenue rose by 7% due to ‘favourable’ pricing, higher volumes and cost-saving programs. It didn’t say whether the cost cutting included sourcing cement from a different supplier! All of this though was counteracted by lower contributions from its Sunstate joint venture (JV) with Adelaide Brighton and higher fuel and clinker costs.
All of this is fascinating because these kinds of disputes usually remain out of the public eye. The large size of Wagners’ cement supply deal with Boral meant that when it was threatened it likely had to tell its shareholders due to the potential financial impact. Whether Boral can wriggle out of the contract is now a matter for the courts.
The broader picture is that even though Boral Australia’s cement division seemed to be growing in its 2019 financial year it was still trying to reduce its costs in the face of a decelerating construction market. Added to this, the companies hold both a supplier and a competitor relationship. On the production side Boral operates an integrated plant at Berrima in New South Wales (NSW), a grinding plant at Maldon, NSW and another grinding plant in its Sunstate JV at Brisbane, Queensland. Wagners runs its own grinding plant at Pinkenba, Queensland. Both companies operate concrete plants. This is not unusual for a concentrated industrial sector like cement but it creates problems for the regulators. Note that, also this week, the Australian Competition and Consumer Commission was reportedly paying attention to the links between Barro Group and Adelaide Brighton. Barro owns a 43% stake in Adelaide Brighton but the authorities are concerned about a possible overlap in the two companies’ roles as suppliers of cement, concrete and aggregates. Any slowdown in construction in Australia seems likely to heighten these kinds of issues.
Australia: The New South Wales Environment Protection Authority (EPA) has fined Port Kembla Milling’s cement and slag grinding plant US$23,000 for allegedly storing raw materials in the open, in breach of its licence conditions. Raw materials, including gypsum and limestone, were allegedly stored in the open at the subsidiary of Cement Australia on at least five occasions since January 2016 in breach of the site’s planning approval and licence conditions. Such materials should be stored in an enclosed location to prevent dust emissions.
“The requirement to store materials in an enclosed building is a key way to ensure dust emissions from bulk materials are prevented. A measure that is very important given the residential areas near Port Kembla port,” said EPA Regional Director Metropolitan Giselle Howard.
In addition to the fines, the EPA has also required Port Kembla Milling to complete an independent raw materials handling audit to confirm appropriate storage and management systems are put in place. The company has made some initial steps to respond to this request, and the EPA will continue to work with the licensee to ensure full compliance.
Australia: The Federal Court has upheld an appeal by the Australian Competition and Consumer Commission (ACCC) and raised a fine against Cement Australia and its subsidiaries for anti-competitive agreements to US$16.1m. Originally the cement producer was fined US$13.4m but the ACCC argued it was too low. A cross appeal by Cement Australia was dismissed.
“The penalties imposed in competition cases are hugely important in deterring anti-competitive conduct, which is why we appealed the original penalties given to Cement Australia,” said ACCC Chairman Rod Sims.
The ACCC first brought the proceedings in 2008 against Cement Australia, Cement Australia Holdings, Cement Australia Queensland (formerly Queensland Cement Ltd), Pozzolanic Enterprises and Pozzolanic Industries. They were related to contracts that were entered into by Cement Australia companies between 2002 and 2006 with four power stations in South East Queensland, to acquire fly ash. The court found contraventions of the Competition and Consumer Act in 2014 and a fine was issued in 2016.
