World: The Global Cement and Concrete Association (GCCA) has published its Cement Industry Net Progress Report 2023. The report highlights the work of the GCCA and its members to lower their CO₂ emissions since signing the 2050 Net Zero Roadmap in October 2021. Initiatives include carbon capture and storage, renewables and alternative materials. These strategies have contributed to a 23% decline in cement and concrete’s CO₂ emissions between 1990 and 2023.

GCCA president and Cemex CEO Fernando González said “We are pleased to present this report, which captures the progress our industry is making towards net zero. But it will take the combined efforts of industry, governments and societies around the world to deliver on this commitment.” He added “This is the decade to deliver, and my number one priority is to facilitate the GCCA roadmap levers, designed to make full decarbonisation of our industry possible.”

The Cement Industry Net Progress Report 2023 is available here on the GCCA’s website.

Australia: Western Australia’s environment minister Reece Whitby has questioned the efficacy of tests submitted by Cockburn Cement in relation to its Munster lime plant in May 2023. The tests showed successes in odour reduction during sand feeding at the plant’s Kiln 6. Business News Western Australia has reported that the government and an independent expert have raised ‘areas of concern’ as to whether the trial represents normal operating conditions for the kiln.

David Scaife, who represents Cockburn District in the Western Australia Legislative Assembly, said "My gripe is not with the workers, it is with the senior management and the directors of Cockburn Cement and its owner, Adbri, who have refused to do the right thing either by moving the lime manufacturing operations to its Kwinana facility or at least making the investments necessary to eliminate the odour."

Kenya: Bamburi Cement reduced its Scope 1 CO₂ emissions by 3% year-on-year in 2022. Data from its Sustainability Report for 2022 shows that the subsidiary of Holcim also increased its alternative fuels substitution rate by 6%, according to the Standard newspaper. The company’s managing director Mohit Kapoor attributed the drop in emissions to the increased use of alternative fuels, using alternative raw materials to substitute for clinker, using renewable energy sources and optimisation of the cement manufacturing process. In line with Holcim Group the company has committed to becoming net zero by 2050.

India: Nuvoco Vistas sold 4.5Mt of cement during the second quarter of its 2024 financial year (FY2024), up by 1.2% year-on-year. Its revenues grew by 7% to US$309m, while its earnings before interest, taxation, depreciation and amortisation (EBITDA) grew by 73% to US$40.4m. The producer achieved specific CO₂ emissions of 462kg/t and an alternate fuel (AF) substitution rate of 14%. During the quarter, it completed debottlenecking projects at the Risda, Chhattisgarh, and Nimbol, Rajasthan, cement plants. The company said that these raised its clinker capacity by 2000t/day. It also secured a new patent, for its fibre reinforced cement composition, and introduced its Concreto UNO and Duraguard F2F premium cements on the Jharkhand market.

Managing director Jayakumar Krishnaswamy said “Our value over volume strategy has positively contributed to the company’s performance. Our trade share has increased from 72% in the second quarter of the 2023 financial year (FY2023) to 74% in the second quarter of FY2024. In addition, the results also demonstrate our commitment to managing the dynamic cost environment through an optimised power and fuel mix, between conventional and clean energy sources.” He added “The expansion at the Haryana cement plant is expected to be completed in FY2024, which will enable us cater to strong demand in the Northern India region.”

Philippines: Holcim Philippines has appointed I Squared Capital subsidiary Berde Renewables to build, maintain and operate two rooftop solar power plants, at its Bulacan and La Union cement plants, respectively. The solar power plants will have a combined capacity of 7.8GWh/yr and reduce Holcim Philippines’ CO2 emissions by 5500t/yr. The Business Mirror newspaper has reported that the projects advance the producer’s aim to reduce its energy-related CO2 emissions by 65% between 2018 and 2030.

Holcim Philippines president and CEO Horia Adrian noted the 20% reduction in overall CO¬2 emissions that the company has already achieved up to 2022 and said “This project further strengthens our ability to support Holcim's net zero direction and the country's nationally determined contributions.”

US: Solidia Technologies has appointed climate consultancy 3Degrees to manage the measurement, verification and sale of carbon credits for CO₂ emissions reductions generated using Solidia Technologies products. Users of the products can deploy the credits against their Scope 3 emissions from cement and concrete, as well as to compensate for other greenhouse gas emissions.

Solidia Technologies chief executive officer Russell Hill said "By partnering with 3Degrees to issue carbon credits, Solidia is providing a mechanism for the marketplace to invest in technologies that will accelerate and enable global carbon emissions reduction.”

Switzerland: Reduced-CO₂ cement catalyst developer Nanogence has secured an undisclosed sum from a consortium of investors led by investment fund CirCap. Nanogence’s catalyst reduces the CO₂ emissions of cement production by 40%, without changing production processes. Tech EU News has reported that the catalyst is capable of increasing cement’s strength and durability compared with that of ordinary Portland cement (OPC) produced without it. Prior to the latest financial development, the company had raised US$2.7m-worth of funding.

CEO Abhishek Kumar said “We are excited to receive the support from incoming renowned investors in this essential journey to accelerate the transition towards a low carbon built world. With growing demand worldwide, we need to align with like-minded strong backers for our growth phase.”

India: Dalmia Bharat sold 13.2Mt of cement during the first half of the 2024 financial year (1 April 2023 – 30 September 2023), up by 9.6% year-on-year 12Mt in the first half of the 2023 financial year. This contributed towards a 24% year-on-year rise in the producer’s earnings before interest, taxation, depreciation and amortisation (EBITDA) to US$144m from US$116m in the previous first half. During the first half of the current financial year, Dalmia Bharat commenced commercial production from its new 500,000t/yr Ariyalur clinker plant and 2Mt/yr Sattur grinding plant, both in Tamil Nadu. The former commissioning raised the company’s clinker capacity to 22.2Mt/yr.

Group managing director and CEO Puneet Dalmia said “We see a multi-year-strong cement demand trend continuing, as India is undergoing a large-scale metamorphosis. We were one of the first ones to foresee this upcycle and started building our capacity ahead of time. In the past 3.5 years, we have added 17.2Mt/yr-worth of cement capacity, which is 65% growth over 2020 financial year capacity. In line with our vision to reach 110 – 130Mt/yr by 2031, we are continuing to make consistent strides in that direction and capitalise upon the huge opportunity ahead of us.”

The company’s cement managing director and CEO, Mahendra Singhi, noted the effects of a ‘reduction in fuel prices, increased usage of renewable power and improvement in key performance indicators.’ He added “We continue to demonstrate our commitment towards the environment, as we have further brought down our CO₂ footprint to 456kg/t of cement, which is one of the lowest in the global cement sector.”

Bulgaria: Titan Cement subsidiary Zlatna Panega Cement plans to invest Euro11m in sustainability-enhancing upgrades to its Zlatnopanegki cement plant in Lovech Province. The work centres around a Euro7m alternative fuels (AF) upgrade, to raise the plant’s AF substitution rate to 70% from 50% in 2022. Besides this, the producer will also invest Euro4m in the construction of a solar power plant at the facility. The solar power plant is scheduled for commissioning in March 2024. General manager Adamantios Frantzis said that the plant will subsequently move on to its ‘next big project,’ consisting of a Euro35 – 50m upgrade, in 2026 – 2028.

Zlatna Panega Cement invested Euro5.7m in capital expenditure throughout 2022, more than double its investments of Euro2.6m in 2021. It is committed to interim CO₂ reduction targets of 5000t/yr (Scope 1) and 3000t/yr (Scope 2 and 3), and net zero CO₂ emissions by 2050.

India: A report by the Council on Energy, Environment and Water (CEEW), funded by power provider BP, has estimated that India’s cement and steel sectors will require capital expenditure (CAPEX) investments of US$627bn in order to reach net zero CO₂ emissions. The report stated that waste heat recovery (WHR) and other efficiency-enhancing upgrades to cement plants can immediately reduce the industry’s emissions by 32%.

United News of India has reported that CEEW CEO Arunabha Ghosh said "Incentivising renewable energy will play a pivotal role in decarbonisation, through lower or no transmission charges at central and state levels. The government of India should develop a policy for and expedite the establishment of a carbon capture, utilisation and storage ecosystem to abate more than half of the emissions from the existing steel and cement plants.” Ghosh added “Since hydrogen will play a key role in its implementation, the next phase of the National Green Hydrogen Mission should focus on this agenda."
