Vicem awards 6Mt cement and clinker import contract in Philippines
24 November 2022Philippines: Vietnam Cement Industry Corporation (Vicem) has awarded a three-year, 6Mt cement and clinker import contract to Fenix (CEZA) International and Gold Falcon Trading Corp. The agreement will have effect from 2023 until 2025. Việt Nam News has reported that Vietnam's Minister of Construction, Nguyen Thanh Nghi, and National Assembly chair, Vuong Dinh Hue, attended the contract's signing in Manila.
Declining demand, primarily from China, has diminished Vietnam's cement exports over past months. Vietnam produced 130Mt of cement in 2021, but consumed just 65Mt.
Belarus: The government has extended Belarusian Cement Company's exemption from paying customs duties and value added tax (VAT) on its goods imports until 31 December 2023. PrimePress News has reported that the cement producer had previously been exempt from payments up until 30 September 2022.
Pakistan Association of Builders and Developers alleges cement industry cartelisation
22 November 2022Pakistan: The Association of Builders and Developers (ABAD) has accused cement producers of cartelisation and called on the government to take 'stern action' following a rise in cement prices. The Business Recorder newspaper has reported that builders believe that the rise does not reflect trends in local raw materials and imported coal prices. Additionally, it comes in spite of a drop in cement demand.
Cockburn Cement increases scope of Kwinana grinding plant project
21 November 2022Australia: Cockburn Cement has awarded US$1.65m-worth of increased work scope to construction company SIMPEC on an existing contract with the producer. Business News Australia has reported that SIMPEC is carrying out work on Cockburn Cement's Kwinana grinding plant upgrade. The cement company is in the process of consolidating its Western Australian cement production at an expanded 1.5Mt/yr facility at the site, at a cost of US$152m. A new US$35.1m clinker terminal at Kwinana Bulk Terminal will receive up to 40,000t/yr of clinker for use at the plant and in fellow cement producer BGC's local operations.
Philippines Department of Trade and Industry backs recommendation to cut import duties on cement
11 November 2022Philippines: The Department of Trade and Industry (DTI) has backed a recommendation from the Tariff Commission (TC) to repeal import duties on Ordinary Portland Cement and Blended Cement. The so-called safeguard measures were originally introduced in October 2019 for a period of three years, according to the Philippine Star newspaper. The latest investigation by the TC was started due to a request by the Cement Manufacturers Association of the Philippines (CEMAP). However, it found that the domestic cement industry was generally profitable and it said, “There is no existence of an imminent threat of serious injury and significant overall impairment to the position of the domestic cement industry in the near future.” CEMAP said it was saddened by the recommendation of the TC and that it would jeopardise the local sector’s progress.
Holcim New Zealand takes receipt of Christian Pfeiffer ball mill
04 November 2022New Zealand: Holcim New Zealand says that it has received a mill for use in its upcoming Auckland cement replacement products import and distribution facility. The company opted for a Christian Pfeiffer ball mill for the project.
Holcim New Zealand says that alternative materials imported via the Auckland facility will eliminate 100,000t/yr of cement from New Zealand's 1.6Mt/yr consumption. The company expects that this will cut 78,000t/yr of CO2 emissions.
Chinese cement producer imports Zimbabwean coal
03 November 2022China/Zimbabwe: A cement producer in China has imported 20,000t of coal from Zimbabwe. The Zimbabwean Coal Producers Association said that the Port of Beira, Mozambique, despatched the order. Mining News has reported that the shipment is a trial, with other orders also anticipated.
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.

South Korea's nine-month Russian coal imports rise in 2022
25 October 2022South Korea: Russia exported 14.9Mt of cement in the first nine months of 2022, up by 31% year-on-year from 11.4Mt in the corresponding period of 2021. Tex Energy Report News has reported that this occurred due to sharp price rises in imported coal from Australia, Canada and Indonesia. Cement producers increased their reliance on these alternative sources of coal after the South Korean government placed sanctions on Russia in March 2022.
Meanwhile in India, Russian coal imports are expected to decline for a second consecutive month in October 2022, by 51% month-on-month to 730,000t. Russian media attributed this to stockpiling by cement market leader UltraTech Cement and others earlier in 2022.
