FLSmidth to supply 11,500t/day kiln line for Shree Cement’s upcoming Nawalgarh cement plant
12 October 2021India: Shree Cement has hired FLSmidth to supply a 11,5000t/day kiln line for its planned Nawalgarh, Rajasthan, cement plant. The line will consist of a six-stage preheater and a three-support kiln. The supplier will also deliver an OK vertical roller mill, which it says has a 5 – 10% lower energy consumption than a standard vertical roller mill. The project focuses on sustainable productivity and emissions control. Shree Cement has opted for JetFlex burners to give the lowest possible nitrous oxide emissions for various fuel types.
Shree Cement managing director Prashant Bangur said “Based on the experience of working with FLSmidth on the installation of a 9,000t/day pyro system at the Raipur, Chhattisgarh, cement plant earlier this year, we felt confident about approaching Carsten Riisberg Lund and his team regarding the Rajasthan project.” He added “Being recognised as a Sustainability Champion by the World Economic Forum is a testament of our emphasis on sustainability at every stage of our operations. The new line will push that agenda even further in terms of lowering the benchmarks on energy consumption and emissions, and thereby reducing our environmental footprint.”
FLSmidth also supplied a second OK mill for Shree Cement’s operations in Kolkata, West Bengal.

Cimpor to establish solar power plants at its cement plants
06 October 2021Portugal: Cimpor has announced plans for the establishment of 1MW solar power plants at each of its three cement plants in Portugal. The Dinheiro Vivo newspaper has reported that the measure comes under a planned Euro130m investment package in upgrades to its cement operations before 2030. The plans include the expansion of the solar power plants to a total capacity of 10MW by 2025. Additionally, the producer will install two waste heat recovery (WHR) plants with a combined capacity of 8MW at its Alhandra and Souselas cement plants. The company is aiming to reduce its indirect CO2 emissions by 30%. It also has an alternative fuel (AF) substitution rate target of 70% by 2030 - compared to 3% in 2020, when it used 150,000t of AF.
Cimpor has previously invested a total of Euro7.2m in dedicated sustainability-related measures.
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.”
Californian governor commits to net-zero cement CO2 strategy by 2045
29 September 2021US: 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.

Federbeton publishes cement industry decarbonisation strategy
22 September 2021Italy: 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.”
LafargeHolcim US to convert Midlothian plant to Portland Limestone Cement production
15 September 2021US: 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.
