UK: Cemex has bought 10 Volvo 460 8x4 tipper trucks for use at its Angerstein Wharf aggregates depot in Greenwich. From there, the trucks will deliver sand and aggregates all around London. The trucks’ bodies are made of lightweight aluminium, and they conform to Euro 6 emissions standards. This corresponds to 80% NO_x emissions reduction and 50% particulate emissions reduction compared to Euro 5 standards.

Cemex UK fleet engineering manager Nigel Ponton said “The addition of these new trucks to our fleet will enable us to better meet customer demand, safely and efficiently. Safety is the number one focus whenever we add new trucks to our operation and these Volvos tick every box in that respect.” Ponton continued “These trucks will all be working in busy streets across London so it’s imperative we provide our drivers with the best tools possible to do the job and help protect any vulnerable road users. Moreover, thanks to the improved fuel efficiencies and enhanced payload these new Volvos are the most sustainable vehicles we’ve ever had and will help decarbonise our delivery footprint.”

Israel: Nesher Cement has been fined US$1.9m for violations of the Clean Air Law at its cement factory in Ramla. The fine was issued for repeatedly exceeding permitted emissions limits, including for mercury/mercury compounds and particulate matter. 22 violations have been recorded since July 2022.

“The recent fine issued against the Nesher Ramla cement plant is a very welcome step forward, but it’s far from enough,” said Knesset member Alon Tal, chairman of the Subcommittee on Environmental and Climate Impacts on Health. “Just a month ago the ministry issued a permit for seven years to the factory, notwithstanding its dubious record as a serial violator of Israel’s Clean Air Law. This makes absolutely no sense.”

Local activists living near the factory were also not satisfied with the value of the fine. “The Environmental Protection Ministry has confirmed that there’s an unusual rate of cancer, especially lung cancer, in Ramla and Lod,” said Benjamin Ruggill, leader of a citizen action group, to local press.

Pakistan: The Pakistan National Forum of Environment and Health (NFEH) has recognised Lucky Cement’s sustainability successes with a prize at the 19th Annual Environment Excellence Awards 2022. The company’s comprehensive environmental management and monitoring plan covers its solid waste, noise pollution and emissions, including particulates. It says that this is essential to preserving the ecosystem in which it operates.

Chief operating officer Amin Ganny said “We believe in environment-friendly practices and are committed to conserving the environment. Implementation of sustainability into our core business operations has always been one of our main objectives.”

UK: HeidelbergCement subsidiary Hanson’s plan for the installation of a carbon capture system at its Padeswood cement plant has proceeded to the due diligence stage for funding from the UK government’s Department for Business, Energy and Industrial Strategy. The project is one of 20 from the East Coast Cluster and HyNet North West Consortium to make the shortlist for this phase of the approval process.

If successful, Hanson will be able to capture 800,000t/yr of CO₂ and produce carbon neutral cement at the Padeswood plant by 2027. It will create 54 new skilled full-time jobs.

Germany: Loesche has published its Sustainability Report of its performance in 2021. The supplier’s Scope 1 and 2 CO₂ emissions declined by 6.1% year-on-year to 229t from 244t in 2020 and by 19% over the two years from 2019, when they totalled 282t. It reduced the share of Scope 2 emissions in the figure to 40% from 41% in 2020 and 45% in 2019.

Loesche offers emissions-reducing products to the global cement industry under the label Greenkey Solutions. These include its A/Fuel and H/combust ranges for alternative fuels and green hydrogen upgrades, its C/Clay range for clay calcining and grinding, its Digital/Ready 4.0! range for predictive process optimisation and smart asset management, its E/Slag range for ground granulated blast furnace slag upgrades and its S/Crete range for waste concrete recycling, as well as audits for retrofits. Together, Loesche says that its products can reduce the global cement sector’s carbon footprint by 90%. Within this, Loesche believes that calcined clay technology alone can reduce cement’s CO₂ emissions by 40% and its energy demand by 21%.

Loesche said that its launch during the year of its H₂Optimum grinding bed spraying system can reduce grinding mills’ water consumption by 50%.

Mexico: Cemex’s consolidated sales grew by 9% year-on-year to US$7.85bn in the first half 2022 from US$7.2bn in the same period in 2021. It sold 32.1Mt of cement, down by 4% from 33.6Mt. Its cement sales volumes rose by 4% in its US and by 1% in Europe, the Middle East, Africa and Asia, but fell by 10% in Mexico and by 3% in South and Central America and the Caribbean. The group says that record levels of alternative fuel usage and a lowered clinker factor helped it to reduce its total CO₂ emissions by 3% year-on-year in the reporting period.

Chief executive officer Fernando González said “I am pleased that our pricing strategy is yielding results and has fully offset inflationary costs in the second quarter of 2022. With improved supply chain dynamics and continued success of our pricing and cost containment strategies, we remain confident we can recover 2021 margins. 


US: National Cement Company of Alabama has reported that the new kiln line at its Ragland cement plant will reduce the plant’s CO₂ emissions by 40%. Its energy consumption will also fall by 30% as a result of the upgrade. The new line includes a 78m-high homogenisation silo, vertical crusher, five-stage preheater and automated clay storage system. AF used in the kiln will include waste tyres, woodchip and sawdust. The new kiln will help in the Ragland cement plant’s transition to 100% Portland limestone cement (PLC) production by 2023, further diminishing its carbon footprint.

Vicat CEO Guy Sidos said "Our ambition is to use AF in all our cement plants around the world. In addition to eliminating fossil fuel energy and replacing it with recycled regional waste, our investments contribute directly to local development. We are proud of the modernisation and transformation of our Ragland site, which was our very first acquisition outside France in 1974."

Philippines: Cemex subsidiary Solid Cement is installing a new US$356m, 1.5Mt/yr line at its Antipolo cement plant. When operational in April 2024, the line will increase the plant’s capacity by 79% to 3.4Mt/yr. Over the first four months of the project since March 2022, Solid Cement invested US$197m in silos and mechanical installation. The new 1.5Mt/yr line will use Low Temperature Clinker technology to reduce its CO₂ emissions, and will also recycle waste hot gases for raw materials drying.

Solid Cement is building the plant using 6000t of its own Vertua reduced-CO2 cement, which it says will further reduce its net carbon footprint by 564t.

Philippines president and CEO Luis Franco said “We will maintain our active role in supporting the development of this nation, as we have done in the past 25 years.”

Canada: The Canadian government’s Environment and Climate Change department has granted an extension to St Mary’s Cement to an order regarding alleged sticky dust emissions from its McInnis cement plant. The Journal de Québec newspaper has reported that the producer now has until 8 August 2022 to submit its observations on the situation. Environment and Climate Change Canada has identified 12 different equipment failures as contributors to the alleged illegal emissions. On 20 July 2022, it had received a total of 80 reports from the public about the situation.

A trio of slag cement stories have been in the sector news this week with reports from Australia, France and Sri Lanka. Of note from the first two reports is a focus on supplies of slag.

The first concerns Hallett Group’s US$80m supplementary cementitious materials (SCM) project in South Australia. This will see the company process slag and fly ash sourced from sites in the region to manufacture blended cement products and standalone SCMs. These will be principally milled, blended and distributed from a site at Port Augusta. However, an additional distribution site at Port Adelaide is also planned that can both import and export the company’s products in a bid to cut down on supply chain risk, particular for its mining customers. The company says it will replace up to 1.15Mt/yr of cement when fully operational, although initial production looks set to be about a third of this based on local media reports. Commissioning of the Port Adelaide distribution hub is scheduled for May 2023, following by the Whyalla Granulator in January 2024 and the Port Augusta processing plant in June 2024. Pointedly, Hallett Group is explicit about where is plans to source its SCMs from: Nyrstar Port Pirie and, potentially, Liberty GFG.

The second slag-themed story hails from France, where Hoffmann Green Cement has acquired ABC Broyage, which operates a slag grinding plant in North Dordogne. Like the project in Australia above, Hoffmann Green is focused on its supply chain. With this acquisition it will be able to grind its own blast furnace slag instead of buying it. Raw blast furnace slag will be imported via the port of La Rochelle where the company has storage silos. It will then be ground at the former ABC Broyage site and sent on to Hoffmann Green’s H1 and H2 production sites, located at Bournezeau in the Vendée region. Finally it will use it to manufacture its H-UKR and H-IONA cement products. There is no mention of how much the acquisition is costing Hoffman Green. Instead the emphasis, according to company founders Julien Blanchard and David Hoffmann, is very much to, “strengthen our control over our supply and secure our margins in the current highly inflationary context.”

Finally, the week’s third slag-themed cement story is from Sri Lanka, where local media reports that Insee Cement has started producing Portland Composite Cement, using SCMs such as slag, at its Ruhunu grinding plant. This story follows the trend of cement producers around the world switching to greater usage of blended cements, often for sustainability reasons. Unfortunately, political events in Sri Lanka are overshadowing everything else locally, with the president having fled amid social unrest provoked by the ongoing and severe economic crisis. To this end Insee Cement has astutely also donated medical supplies this week to the intensive care unit at the Colombo National Hospital.

These slag stories are important for the cement sector can be demonstrated by a recent update to the Center for International Climate and Environmental Research - Oslo’s (CICERO) research on global CO₂ emissions from cement production. When it published its estimate for 2021 it found that overall emissions were 2.6Bnt in 2021 or just over 7% of the world’s total CO₂ output. What is worse though, is that its data suggests that cement-based emissions have steadily grown year-on-year from 1.2Bnt in 2002. Apart from a dip in 2015 they have kept on rising! This can mostly be attributed to the growth of the Chinese cement industry in the early 2000s suggesting that a tipping point may be reached in the current decade as lowering cement production CO₂ intensity finally kicks in.

Slag and other SCM-based blended cements fit in here as they are one of the ‘easiest’ ways to reduce the clinker factor of cement and concrete and thereby reduce the sector’s CO₂ levels. Hence they keep popping up on the various roadmaps and reports for the cement industry to reach net zero. The flipside of this however is that slag is becoming harder to source as the demand for granulated blast furnace slag increases and less new steel plants get built, especially in North America and Europe. Hence the focus on the supply of slag in the first two news stories above. Blended cements may be the future but getting there will be far from simple.
