India: ACC and Ambuja Cements have partnered with the Indian Institute of Technology Delhi (IITD) to develop a range of calcined clay cements with 50% lower CO₂ emissions than Ordinary Portland Cement (OPC). The collaboration will vary clinker, calcined clay and limestone levels in calcined clay cements in order to ascertain their effects on its performance. France-based Holcim Innovation Centre will fund the research.

Holcim India chief executive officer and managing director Neeraj Akhoury said "Through our extensive research and development setup, we consistently strive to develop new low-CO₂ materials for the construction industry. Calcined clay cement is one such avenue to make a significant quantitative difference in the industry and further accelerate our sustainability drive. Our academic partnership with IITD is a big step towards building a greener future and we are excited to collaborate with the best minds in the country."

The producers have previously partnered with the Indian Institute of Technology Madras (IITM) to study low-CO₂ binders with alternative reinforcements and with the Indian Institute of Technology Hyderabad (IITH) to develop smart sensing technology for continuous on-site strength evaluation of a concrete structure.

UK: Breedon Group has told investors that its consolidated sales in the first ten months of 2021 were Euro1.24bn, up by 31% compared to their levels in the corresponding period of 2020. The group said that its ‘layered hedging policy’ mitigated key commodity cost pressures during the period. As such, it raised its 2021 full-year underlying earnings before interest, depreciation and taxation (EBIT) forecast to more than Euro145m.

Austria: W&P Zement has installed a Euro2.5m new raw materials processing plant at its Peggau quarry in Styria. The plant will introduce modern washing and sieving processes to operations at the quarry, with an additional sludge buffer for the processing of clayey material. Project manager and mining manager Jürgen Kolp said that the plant will improve the sustainability of the company’s raw materials extraction operations by increasing the limestone yield from excavated raw material.

Italy: Buzzi Unicem’s consolidated sales rose by 5.6% year-on-year to US$2.54bn in the first nine months of 2021 from US$2.41bn in the first nine months of 2020. It recorded consolidated cement sales of 23.4Mt, up by 7.5% from 21.7Mt in the corresponding period of 2020. Sales growth in Eastern Europe - especially the Czech Republic and Poland - and the US offset a partial slowdown in Italy, particularly in the third quarter of the year.

The group expects global construction activity to generally remain level into the fourth quarter of 2021. It forecast “favourable” volume and price effects in its full-year results for 2021. It nonetheless noted “growing concern” at rising energy, fuels, logistics, raw materials and services costs in various regions. It forecast group recurring earnings before interest, taxation, depreciation and amortisation (EBITDA) not in excess of 2020 levels.

Pakistan: Members of the All Pakistan Cement Manufacturers Association (APCMA) plan to reduce the CO2 emissions from their cement production. The Business Recorder newspaper has reported that companies will take three routes to emissions reduction while continuing to meet increased demand. These are to increase the efficient use of materials, increase energy efficiency and employ new technologies to capture or eliminate emissions.

President Muhammad Ali Tabba said "In a bid to achieve green growth going forward, the cement industry globally will have to adapt to climate change challenges and rework business models to ensure environmental stewardship and robust growth. The cement industry in Pakistan is committed to playing its role."

Argentina: Sit-in protesters from the Argentinean Mining Workers Association (AOMA) have blocked access to the hoppers of limestone crushers at Minerar’s Olavarría quarry, according to the Clarín newspaper. The quarry supplies limestone to Loma Negra’s La Amali cement plant.

The cement producer said “The biggest problem is that if they don't solve the problem, and stop the supply raw material, it will complicate cement production."

World: Forty cement and concrete producers, representing 80% of concrete production outside of China in 2020, have together affirmed their commitment to the Global Cement and Concrete Association (GCCA)’s Roadmap to Net Zero concrete decarbonisation strategy. The roadmap’s seven-point plan consists of increased cement plant efficiency, which should eliminate 22% of emissions, increased concrete production efficiency (11%), adjustments to cement and binders (9%), decarbonisation of raw materials (11%), carbon capture and storage (CCS) (36%), a transition to renewable energy (5%) and the natural recarbonation of concrete (6%).

Besides full decarbonisation by 2050, the strategy provides for a 25% reduction in the global concrete sector’s CO₂ emissions by 2030 and the elimination of 4.9Bnt of CO₂ emissions by 2030 alone. The GCCA called the new commitment a ‘significant acceleration’ of cement and concrete producers’ on-going decarbonisation efforts, and said that it represented ‘the biggest global commitment by any industry’ to carbon neutrality. Acknowledging the burden on cement producers, the GCCA called on downstream companies and governments to support the industry’s transition.

GCCA member China National Building Material (CNBM) CEO Cao Jianglin said “This is a landmark for industry co-operation in decarbonisation. As part of a global industry, it will need collaboration across our sector to achieve it. As one of the leading cement and concrete producers in China, we will play our part in decarbonising the industry.”

Poland/US: Holcim has announced two new acquisitions in the area of raw materials and aggregates. In Poland, it has acquired granulated calcium carbonate producer Polcalc. The company employs 78 people. In the US, the group has acquired Utah-baed Utelite. The company produces lightweight aggregates and employs 40 people.

CEO Jan Jenisch said “We are pleased to welcome the employees of Utelite and Polcalc and look forward to their experience and capabilities. These two bolt-on acquisitions strengthen our presence in two important growth markets while contributing to Holcim’s overall strategy to expand our range of low-carbon products and solutions.”

Germany: Cemex Zement has launched Insularis cement-free concretes, a product range suitable for use in building insulating components. The range includes lightweight concretes Insularis Supra and Insularis Infra. Due to its low bulk density, Insularis Infra currently requires special case-by-case or project-related approval for use in Germany. The company said that it produces Insularis concretes from a mix of recycled and natural raw materials. It added that Insularis is itself 100% recyclable.

China: Anhui Conch’s operating revenue grew by 8.7% year-on-year to US$12.5bn in the first half of 2021 from US$11.5bn in the same period in 2020. However, its net profit fell by 7% to US$2.32bn from US$2.49bn. The group blamed this on rising raw material prices and ‘fierce’ competition. Anhui Conch reported that its production and sales volumes of cement and clinker increased by 11.5% to 208Mt. By region, sales grew in east, central and south China but fell in the west.

The group said that one clinker production line and two cement grinding units for Hunan Yunfeng Cement had been commissioned during the first half of 2021. Construction work on two grinding projects based in Haimen and Ganzhou also started. Outside of China, work on the group’s Qarshi project in Uzbekistan progressed to the installation of equipment.
