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%.

Philippines: Holcim Philippines has launched its ECOPlanet 30% reduced-CO₂ cement range in the city of Davao on Mindanao. The producer also introduced its Balik-Plastic waste cement bag recycling programme, offering a collection service to customers in order to reuse waste bags as alternative fuels and raw materials in cement production at its Davao plant.

India: Dalmia Bharat sold 6.2Mt of cement in the first quarter of its 2023 financial year, up by 27% year-on-year from 4.9Mt in the first quarter of its 2022 financial year. Its sales revenues also rose by 27%, to US$417m from US$327m. The growth failed to translate into increased profitability, however, with the company recording a profit after tax of US$25.9m, down by 27% from US$35.3m.

Dalmia Cement (Bharat) Managing Director and CEO Mahendra Singhi said “I am pleased with our performance this quarter. Our sustained efforts on operational efficiencies and cost rationalisation have enabled us to mitigate the adverse impact of inflation and deliver our lowest total cost of production. Our capacity expansion projects are on track, and we have added 2Mt/yr of clinker capacity and 1.1Mt/yr of cement capacity, which takes our cement capacity to 37Mt/yr. We remain firm on our Carbon Negative Roadmap, and during the quarter have installed 41.4MW of renewable energy infrastructure.”

Argentina: ECOPact reduced-CO₂ concrete accounted for 50% of Holcim Argentina’s cement deliveries at the end of the first half of 2022, a higher share than in any other country apart from the UK. Holcim launched ECOPact concrete across its markets in June 2021. Holcim Argentina plans to execute new investments to further increase its distribution of the product.

The company’s head of concrete José Villacreses said “We have set ourselves even more challenging goals. We will be the undisputed ally for sustainable projects throughout Argentina. Whoever wants to measure their carbon footprint to offer sustainable construction will find in Holcim the necessary solution to be able to achieve the certifications that society demands today.”

US: GCC plans to invest US$750m in an upgrade to its 0.9Mt/yr Odessa cement plant in Texas. The Milenio newspaper has reported that the upgrade will more than double the plant’s capacity to 1.9Mt/yr and lower its CO₂ emissions per tonne of cement by 13%. GCC expects the new capacity to be operational by 2025.

The group said “GCC will carry out the project at the Odessa plant because the US market is developing faster and represents savings in freight compared to the plant located in Chihuahua, Mexico.”

New Zealand: Golden Bay Cement says that proposed changes to New Zealand's emissions trading scheme (ETS) would force it to review the viability of cement production at its 0.9Mt/yr Portland cement plant in Whangārei, Northland. The Northern Advocate newspaper has reported that the government proposes to reduce the number of ETS credits available to industrial enterprises under free allocation from 2024.Since the scheme's introduction in 2008, highly emissions-intensive businesses such as Golden Bay Cement have enjoyed 90% free allocation of ETS credits for their emissions.

Greece: Titan Cement Group has successfully started a pilot CO₂ capture demonstration project at its Kamari plant. As part of the RECODE2020 project it said it had reached a CO₂ purity above 99% during initial operation by using ionic liquids as the CO₂ adsorbents. The captured CO₂ is then intended to be utilised by converting it to nanocalcite and additives that can reused in cement production in different ways. The cement producer is also running the CARMOF project at the plant.

Nigeria: Dangote Cement says that it raised the thermal substitution rate of alternative fuels (AF) in its group cement production by 25% year-on-year in the first half of 2022. It co-processed 67,200t of locally-sourced waste in its operations during the half.

Chief executive officer Michel Puchercos said “Although significant increases in energy and AGO costs are impacting production, we are strengthening our efforts to ramp up the usage of AF. Our on-going Alternative Fuel Project aims to leverage waste management solutions, reduce CO₂ emissions and source material locally.”

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.
