US: The Nevada Department of Transportation has approved the use of Portland limestone cement (PLC) for road construction and repairs. The department expects the move to reduce CO₂ emissions by 4000t/yr. It uses 45,000t/yr of cement in its projects. Local press has reported that transport contributed 35% of Nevada’s CO₂ emissions in 2022, making it the largest single source.

Morocco: Holcim subsidiary LafargeHolcim Maroc has released information about its 1.6Mt/yr Agadir cement plant in Souss-Massa Region. The producer invested US$299m in the plant’s construction and it has been operational since late 2021. The plant is highly automated in line with Holcim’s Plants of Tomorrow strategy. It will run off wind power from 2023, and also uses alternative fuel (AF). 200 people work at the plant.

In conjunction with its work in setting up the new cement plant, LafargeHolcim Maroc developed drinking water networks in the surrounding area, including the construction of three solar-powered water towers.

Austria: RHI Magnesita’s customers can now rely on Environmental Indicators on all of its products’ Technical Data Sheets to check their CO₂ emissions. The indicators state the CO₂ equivalent emissions per tonne of each product. The supplier calculated the figures in line with ISO standards under on-going external supervision.

Chief sustainability officer Gustavo Franco said “One of RHI Magnesita’s main targets is to significantly reduce emissions over the next few decades, with the long-term goal of achieving net-zero operations in all areas of the company. It is clear that a solid basis for sustainable decisions and developments can only be achieved by creating a valid audited database.”

UK: The World Economic Forum and the Global Cement and Concrete Association (GCCA), in collaboration with Boston Consulting Group (BCG), have released a Mission Possible Partnership Report which identifies the nations that are prioritising green public procurement. These are the Netherlands, Sweden, Germany, France, the UK, and select US states. The report titled ‘Low-Carbon Concrete and Construction - A Review of Green Public Procurement Programmes’ identifies a framework for how these six countries are demonstrating leadership in green public procurement of concrete and construction.

The first component of the framework is the foundation, which includes establishing standards for reporting emissions, databases and tools for tracking emissions and establishes baselines. The second part of the framework, procurement polices, builds upon and reinforces the foundation by setting policies that require environmental disclosures, mandate carbon limits, and incentivise low-carbon design, and use of low-carbon materials.

Approximately 7% of global carbon emissions come from cement, and about half of the cement used globally is procured by the public sector. Governments also spend US$11tn/yr on procurement, about 12% of global gross domestic product (GDP) and regulate the construction industry via building codes. Therefore, governments play a critical role in driving demand to decarbonise the concrete and construction sector to achieve net zero goals.

Matt Rogers, the chief executive officer of the Mission Possible Project said “The demand signals in the market for green industrial products are among the most important opportunities to accelerate the path to net zero across industrial sectors. For material sectors like cement and concrete, government procurement practices will play an especially important role. This report summarises the current best practices in government procurement for green cement across multiple markets. Insights like these provide the government procurement professionals practical tools and technical insights that they can use today to create demand-pull for the most innovative low carbon cement and concrete offerings in the market.”

US: The Portland Cement Association (PCA) has opposed a proposed federal temporary suspension to a petrol tax. PCA president and chief executive officer (CEO) Mike Ireland said, “Pausing the federal gas tax is the wrong decision at the wrong moment. Gas tax revenues fund the Infrastructure Investment and Jobs Act (IIJA), which is a once-in-a-lifetime opportunity to remake American industry and infrastructure with sustainability at its core. Removing the funding from the gas tax will strangle the IIJA before it is even up and running.”

The passage of the IIJA has coincided with PCA's launch of its Roadmap to Carbon Neutrality, which outlines the steps needed to achieve carbon neutrality across the entire cement-concrete-construction value chain by 2050. The PCA says that implementing the changes in its roadmap will require ‘significant’ funding such as those generated from the petrol tax.

Austria: RHI Magnesita says it has released CO₂ emissions data for all of its 200,000 products. Technical Data Sheets now include a field ‘Environmental Indicators’ in which the CO₂ equivalent emission of one metric ton of the product is listed. The calculation method for these indicators is developed with and supervised on an on-going basis by an external organisation under the principles of ISO standards. All greenhouse gases ‘cradle-to-gate’, from raw material extraction to production to packaging to gate are considered in these CO₂ footprint calculations.

Chief sustainability officer Gustavo Franco said "This project marks an important milestone towards a green transformation. Thus, one of RHI Magnesita's main targets is to significantly reduce emissions over the next few decades, with the long-term goal of achieving net-zero operations in all areas of the company. It is clear, that a solid basis for sustainable decisions and developments can only be achieved by creating a valid audited database."

Pakistan: DG Khan Cement has despatched a shipment of 50,000t of cement for Houston, US, from Karachi. The Balochistan Times newspaper has reported that the shipment is the first of 12 consignments of the same size under an order for 600,000t of low-alkali cement. If successful, the order may double to 1.2Mt. The producer is using jumbo bags to transport the product on its 42-day journey overseas.

Marketing director Fareed Afzal said that Pakistani businesses need to diversify their export markets and strengthen foreign currency reserves. He added that DG Khan Cement continues to reduce its products' carbon footprints by using renewable energy, waste heat recovery (WHR) and alternate fuels (AF).

Australia: Adbri is part of a consortium of eight Australian industrial manufacturers, developers and port operators collaborating with AGL Energy on a feasibility study for a green hydrogen plant at the site of the latter’s Torrens Island power plant in South Australia. AFR Online News has reported that any future hydrogen plant established by the partners would rely on solar and wind power, which has large potential in the region.

The South Australian government previously launched its first US$414m green hydrogen project in Whyalla in March 2022.

Pakistan: Fauji Cement says that its sustainability initiatives across its three cement plants reduced CO₂ emissions by 215,000t in the 2022 financial year. The Pakistan Today newspaper has reported that clinker factor reduction in reduced-CO₂ products such as Askari Green cement and Pamir cement eliminated 89,900t-worth of emissions, 42% of total reductions. Waste heat recovery (WHR) plants eliminated 79,400t of emissions (37%), solar power plants eliminated 31,500t (15%), alternative fuel (AF) substitution eliminated 8030t (3.5%) and reforestation eliminated 600t (2.5%).

Belgium: Holcim Belgium hopes to complete its Obourg cement plant’s Go4Zero oxyfuel kiln conversion and carbon capture installation project by 2025, in order to achieve carbon neutrality at the plant by 2030. The producer says that the plans involves establishing a new 135m-high cooling tower, instead of a 145m-high tower as previously planned.

In an effort to rally local support, Holcim Belgium will begin offering virtual reality (VR) tours of the upgraded plant plans in September 2022.

Chief executive officer Bart Daneels said “We would like to start this project, which will be a world premiere in the cement industry.”
