US: GCC plans to fully convert production at its 0.35Mt/yr Trident Plant in Montana to Portland Limestone Cement (PLC) in early 2022. The cement producer estimates that the plant’s production change will reduce its CO₂ emissions by almost 25,000t/yr.

“We believe that our industry must continue to provide the homes, roads and infrastructure that shape our world while, simultaneously, addressing the challenge of climate change,” said Ron Henley, president of GCC’s US division. “PLC is one piece of the puzzle to reduce greenhouse gases. Concrete made with PLC is a resilient material that easily meets the needs of our customers for generations to come.” He added that GCC signed the Global Cement and Concrete Association’s (GCCA) net zero pledge earlier in 2021.

India: Ambuja Cements has commenced commercial production at its new 3Mt/yr Marwar cement plant in Nagaur, Rajasthan. The plant has and an additional 2Mt/yr of grinding capacity. The Orissa Diary newspaper has reported that the producer invested US$316m in its construction. The Marwar cement plant increases Ambuja Cement’s installed capacity by 20% to 29.7Mt/yr.

Managing director Neeraj Akhoury said “Ambuja has ambitious growth plans to expand its capacities in India, and the Marwar plant is a step in that direction. We are very proud that it is a ‘green plant’ designed to meet our ambition for a sustainable future. The plant has deployed all modern equipment and technology to produce cement in a more environmentally friendly manner. It has a waste heat recovery (WHR) system that converts waste heat derived during the production process into energy.”

US: California Governor Gavin Newsom has signed a bill requiring the California Air Resources Board (CARB) to develop a plan by mid-2023 for the state’s cement producers to achieve net zero emissions of greenhouse gases by the end of 2045 at the latest. A 40% reduction compared to 2019 levels would also be required by the end of 2035 with interim targets set beforehand. CARB will also be obliged to ‘define a metric for greenhouse gas intensity,’ monitor emissions data, set a baseline to measure emissions reduction progress, evaluate measures to support market demand and financial incentives to encourage the production and use of low-carbon cement amongst other actions.

Thailand: SCG Packaging has taken a US$148m four-year loan from Bank Ayudhya. The loan is subject to environmental, social and governance (ESG) criteria and key performance indicators. The loan’s interest rate is tied to the company's sustainability performance targets, namely reducing greenhouse gas emissions, managing water resources and increasing the sales portion of its Green Choice label products and services. Bank Ayudhy will serve as sustainability coordinator, with the ability to adjust it down annually if sustainability goals are met.

India: UltraTech has made a commitment to transition to 100% renewable energy use by 2050. The Aditya Birla subsidiary has joined the global RE100 group of companies committed to energy decarbonisation. Asian News International has reported that the producer is already targeting 34% renewable energy use by 2024 from 13% in 2020. It more than doubled its consumption of renewable energy between 2018 and 2020. UltraTech Cement is additionally targeting a CO2 emissions reduction to 462kg/t of cement. It is the first Indian producer to instigate sustainability target-linked financial commitments.

Italy: The Italian cement association Federbeton has launched its comprehensive plan for cement industry decarbonisation in line with the EU’s European Green Deal target of a 55% reduction in CO₂ emissions between 1990 and 2030 and carbon neutrality by 2050. The strategy entails Euro4.2bn of total new investments andEuro1.4m/yr of extra operating costs across the industry. This will cover the adoption of transition technologies and the large-scale application of carbon capture and storage (CCS). The association says that while some such actions, such as alternative fuel (AF) substitution,are immediately available, others require further development. The sector’s primary fuel is petcoke, mainly imported from the Gulf of Mexico. As such, Federbeton has identified the 100% replacement of all fossil fuels with ‘low-carbon impact’ alternatives as a means of reducing the industry’s carbon footprint by 12% achievable in the short term. Renewable green hydrogen use can cut a further 3% of CO₂ emissions, an energy transition to renewable sources can cut 5%, clinker factor reduction can cut 10%, alternative raw materials in clinker can cut 6%, CCS can cut 43%, supply chain and logistics changes can cut 16% and the optimisation of construction can cut the remaining 5%.

President Roberto Callieri said “The cement and concrete supply chain wants to be one of the protagonists of the ecological transition.” He added “Only with adequate and immediate support tools will it be possible to prevent the impoverishment of the industrial fabric, preserve the competitiveness of the supply chain and prevent relocation. Last but not least, a new environmental culture must be shared, based on dialogue and no longer on the preconceived opposition to any choice of industry.”

US: LafargeHolcim US says that the integrated 2Mt/yr Midlothian plant in Texas will become the first cement plant in the country to fully convert to Portland Limestone Cement (PLC) production. The unit will switch to producing the company’s OneCem product, a blended cement manufactured with up to 15% of finely ground limestone. The move is intended to help LafargeHolcim US and its customers meet sustainable construction goals and lower carbon emissions.

“This is an important, but not unique, step for us. We were the first to produce OneCem, a PLC product, in one of the fastest-growing metro areas in the country, and fuel our industry’s step towards a zero carbon future,” said Patrick Cleary, senior vice president of sales, LafargeHolcim US Cement.

The company is promoting OneCem as an alternative to Ordinary Portland Cement in terms of concrete workability, set time, durability and strength development. It can be incorporated into a broad spectrum of applications that will support foundational structures. The product is available in the Western and Southern regions of the US and the company plans to ‘rapidly’ expand production.

Mexico: Cemex has partnered with Sweden-based Volvo to develop a zero-emissions cement fleet. The implementation will extend to mobile construction equipment, trucks, productivity solutions, and uptime services. A Cemex European site will host trials of the technologies.

Head of global sustainability Vicente Saiso said “Working together with a leading global company in electromobility construction equipment and trucks such as Volvo will strengthen our efforts to address climate change and reduce our carbon footprint to reach net zero by 2050. We are excited to collaborate and develop a roadmap to introduce electric trucks and equipment throughout our operations.”

Germany: The German Cement Works Association (VDZ) has lobbied national and European Union governments for ‘appropriate and reliable’ framework conditions for the industry’s to realise its sustainability objectives. Its Environmental Data of the German Cement Industry 2020 report set out the sector’s agenda under three overlapping headings: climate neutrality by 2050, preservation of primary raw materials and air pollution control. The VDZ said that government support for the necessary ‘unprecedented’ reduction in CO₂ emissions will be especially vital in the area of renewable power and the creation of a functioning CO₂ infrastructure.

VDZ president Christian Knell said “The often bureaucratic and complex processes involved in approval procedures and applications for funds to finance necessary investments are a cause for concern.”

China: Anhui Conch has signed a CO₂ trading agreement with Shanghai Environmental Energy Exchange (SEEE). The deal takes place within the context of Shanghai’s CO₂ trading pilot scheme. Anhui Conch says that it will not only facilitate the promotion of carbon allowance asset scheduling and carbon asset market transactions, but also provide accreditation and CO₂ management system certification. It says that SEEE will help it to better assume the role of a leading enterprise in the ‘dual-carbon’ field of the cement industry.

Anhui Conch says that it is focusing on developing a full-process carbon footprint monitoring system. It has begun researching the utilisation possibilities of captured carbon with academic partners.
