Ireland: CRH recorded sales of Euro28.3bn in 2019, up by 6% year-on-year from Euro26.7bn in 2018. Earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 25% year-on-year to Euro4.20bn from Euro3.36bn. The company said that the results were supported by a positive demand backdrop in the Americas and in key regions in Europe. It also set out a new CO₂ emissions roadmap with target of 520kg/t of cement by 2030, a 33% reduction compared to 1990 levels.

Colombia: In 2019 Grupo Argos subsidiary Cementos Argos’ sales rose by 11% year-on-year to US$2.8bn from US$2.5bn in 2018 and its earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 14% year-on-year to US$0.5bn from US$0.4bn in 2018. Cement dispatches rose by 0.6% to 16Mt. In the US, its main market, the company sold 6.3Mt of cement, up by 9.5% from 5.8Mt in 2018.

Argos CEO Juan Estaban Calle praised the company’s successes in 2019, such as the completion of its Thermally Activated Clays (TAC) project at its 1.4Mt/yr integrated Cementos Rioclaro plant in Colombia. “This allows for production and distribution of green cement with a greatly reduced clinker factor, 38% lower CO₂ emissions and 30% of the energy consumption of ordinary Portland cement (OPC) production,” he said.

Mexico: Cemex has announced a new Climate Action strategy, which outlines the company’s vision to advance towards a carbon-neutral economy and to address society’s increasing demands more efficiently. The company states that it believes climate change to be one of the biggest challenges of our time and support collective action.

It says that it has already reduced its net specific CO2 emissions by more than 22% compared to its 1990 baseline. It has now defined a more ambitious target of a 35% reduction of net specific CO2 emissions by 2030. This new goal is aligned with the Science-Based Targets methodology, a requirement that is necessary to meet the goals of the Paris Agreement. To complement this strategy with a longer-term vision, Cemex is also establishing a new ambition to deliver net-zero CO2 concrete by 2050.

“Climate change has been a priority for Cemex for many years,” said Fernando A Gonzalez, Cemex CEO. “Our efforts have brought significant progress to date, but we must do more. This is why we have defined a more ambitious strategy to reduce CO2 emissions by 2030 and to deliver net-zero CO2 concrete by 2050.”

To fulfil this strategy, Cemex has a laid out a CO2 roadmap to accelerate the roll-out of proven technologies across its facilities, including investing in energy efficiency, using alternative fuels, expanding the use of renewable energy, and increasing the substitution of clinker with alternative cementitious materials. It says its aim of net-zero CO2 concrete will require open innovation that requires strategic partnerships and cross-industry collaboration in the development of breakthrough technologies like CO2 capture, storage and utilisation, novel clinkers with low heat consumption, alternative decarbonated raw materials, carbonation of concrete waste for use as recycled aggregates, and the promotion of circular economy models that transform waste into fuel.

Vietnam: The Vietnam National Cement Corporation (Vicem) and Denmark-based supplier FLSmidth have announced a cooperation agreement with the aim of radically reducing the greenhouse gas emissions from cement production and improving air quality. The cooperation will consist of Vicem implementing solutions pioneered by FLSmidth. FLSmidth said that a key focus of the cooperation will be Vicat’s use of ‘municipal and other waste streams as alternative fuel sources,’ with the aim of achieving 100% substitution using FLSmidth solutions, in accordance with FLSmidth’s ambition ‘to enable cement companies to operate with zero emissions by 2030.’

Mexico: Grupo Cementos de Chihuahua (GCC) says it will commit to setting greenhouse gas reduction targets in line with climate science by joining the Science Based Targets initiative (SBTI). GCC will set science-based emission reduction targets in line with the level of decarbonisation required to keep global temperature increase well-below 2°C compared to pre-industrial temperatures, as described in the latest Special Report of the Intergovernmental Panel on Climate Change (IPCC).

“By joining the SBTI, GCC will ensure that the company´s low-carbon transformation is aligned with climate science and is a further reflection of our unwavering commitment to implement global best practices related to sustainability,” said Enrique Escalante, GCC´s chief executive officer (CEO).

UK: CemFree cement-free concrete has been applied volumetrically for the first time in a 52m3 repair to the Woodford West Viaduct on the M25 London ordbital motorway in Essex. The reason behind the choice of method was the unavailability of batching plants at night, which was the only time that a team of Jackson, DB Group and Axtell employees working on behalf of Connect Plus were permitted to perform the work on the UK’s busiest road. CemFree said that 9.4t of CO2 emissions were cut by comparison to the same project undertaken with ordinary Portland cement (OPC). Jackson director of highways Paul Watson said, “We hope this marks a turning point on the M25 and the wider Highways sector for using low carbon alternatives.”

Cemfree uses 95% ground granulated blast furnace slag (GGBFS) and a 5% alkali activator, removing the need for cement. This gave CO2 emissions of 114kg/t, which the company says is 77% lower than conventional (OPC).

Germany: Research from the Potsdam Institute for Climate Impact Research (PIK) has suggested that wood, including fast-growing bamboo, could supplant 50% of cement and steel used in construction, cutting global CO₂ emissions by up to 880Mt/yr and providing a carbon sink for close to 700Mt/yr of CO2 emissions. Assuming a no-change scenario in cement production practices, PIK fellow Galina Chakina says, ‘the shift to timber would make quite a difference for achieving the climate stabilisation targets of the Paris agreement.’

Germany: Holcim Deutschland has announced the successful development of Holcim EcoPact Zero, a net-zero carbon concrete. It says that it is in talks with customers in Germany and will make the first deliveries of EcoPact Zero in early 2020. Holcim Deutschland CEO Thorsten Hahn said, “The use of clinker-reduced cements and the optimisation of the binder content play a central role. The still unavoidable CO₂-footprint is fully offset at with the support of various certified environmental projects.”

Uzbekistan: The State Committee of Uzbekistan for Ecology and Environmental Protection plans to create a system of monitoring stations for automatic measurement of air pollution, including particulate matter (PM), throughout the country. Part of this will include the installation of automatic emissions sampling and analysis stations at a number of industrial plants, as well as static monitoring stations within and near plant sites, including in the cement sector. Installation will be at the cost of the industrial facility.

In late 2019 the State Committee for Ecology, together with the Ministry of Health and Uzhydromet, took samples of air from 13 cement plants, finding that five greatly exceeded international norms for dust emissions. Based on the results of the audit, the committee has developed a draft government decree on strengthening environmental control over cement plants. If the document is approved, then all existing cement manufacturers will be obliged to install automatic sampling stations for analysis of air pollution by 1 January 2022, as well as stationary posts in the adjacent territory at their own expense.

Germany: A Zollernalb, Baden-Württemberg resident who mounted legal action against Tübingen Council in June 2019 over LafargeHolcim subsidiary Holcim Süddeutschland’s use of waste glass in cement production at its 1.1Mt/yr integrated Dotternhausen plant has submitted ‘extensive reasoning’ for the challenge. The Schwarzwälder Bote has reported that Holcim Süddeutschland allegedly did not complete the proper tests before introducing glass to cement production at Dotternhausen in late 2017. The claimant ‘noticed a rise in heavy metal levels.’

At a subsequent council meeting, a Holcim Süddeutschland employee bore witness to the presence of a defective bag filter. By receiving glass ground to grains of a certain fineness, the claimant alleges that Holcim Süddeutschland was able to bypass federal waste regulations necessitating contaminant checks. They said the company was ‘taking citizens for idiots.’
