India: 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.

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.”

US: The California State Senate has voted in favour of a bill to implement the US’s most advanced statutory framework for cement industry decarbonisation by 74 votes to two. The statute provides for the implementation of lifecycle CO₂ emissions reporting for cement produced in the state at an estimated cost of US$220,000/yr. The California Air Resources Board will then implement a ‘programme developed as a result of identified strategies’ at an ‘unknown but significant cost.’ The aim of the strategy will be to facilitate a 40% reduction in cement production’s CO₂ emissions between 2019 and 2030 and the attainment of net zero cement production by 2045.

US: The US Department of Energy has selected Central Plains Cement to receive US$5m-worth of funding to realise its plans for a cryogenic carbon capture (CCC) installation at its Sugar Creek, Missouri, cement plant. Contify Energy News has reported that the system will initially have a capacity of 30t/day of CO₂, with a view to eventually capturing 95% of the plant’s flue gas’ CO₂ content. The Eagle Materials subsidiary will receive US$5m in funding from the US Department of Energy for the project. The sum is part of a raft of a total US$45m-worth of grants to help towards decarbonising heavy industry and natural gas power. Chart Industries will carry out the work.

Chart Industries CEO and President Jill Evanko said that the company’s CCC model increases cement production costs by just 24%, compared to 38% - 130% for other types of system. She added “We are delighted that public and private entities recognise Chart as a leader in carbon capture technologies and products; we view this award as well as our third quarter 2021 commercial activity as meaningful steps and accelerators toward capturing - pun intended - a significant share of our anticipated US$6bn total addressable market for carbon and direct air capture in 2030.”

The St Louis Post newspaper has reported that Holcim US’s Ste-Genevieve, Missouri, cement plant is also among facilities chosen to receive funding for carbon capture and storage (CCS) installations.

Mexico: Cemex has received validation from the Science-Based Targets Initiative (SBTi) for its 2030 global CO₂ emissions reduction targets. The validation attests that the targets conform with the Paris Agreement’s well-below 2°C global warming limit. Under its Future in Action programme, Cemex aims to reduce its cement’s carbon footprint to 40% compared to 1990 levels and achieve 55% renewable energy use by 2030. The company says that it has the global cement industry’s most ambitious 2030 targets.

CEO Fernando Gonzalez said “Climate action is the biggest challenge of our times. Cemex is taking decisive action to address it by defining ambitious emissions reduction targets in line with the SBTi, and executing against those targets.” He added “We commit to continue leading the industry in climate action not only because it creates value, but more importantly because it is the right thing to do. Cemex is building a better future, and that future must be sustainable.”

Russia: Holcim Russia has committed to realising a 15% CO₂ emissions reduction in its cement production between 2019 and 2030 to 475kg/t from 561kg/t. It plans to further reduce its cement’s CO2 emissions to 453kg/t by 2050, and to implement further measures to ensure its net carbon neutrality at that time.

Corporate relations director Vitaly Bogachenko said “The company's goal is to drastically reduce carbon emissions, and there are two working solutions for this. The first is the use of alternative fuels (AF) obtained from different types of waste: residues of municipal solid waste after sorting and extraction of all useful fractions from them, used tyres and others. The presence of biomass in them makes such fuels carbon neutral, so emissions during production are significantly reduced. The second solution is to replace carbon intensive raw materials. For example, instead of limestone, we use slags. The 'recipe' for cement is completely different: thanks to the new composition and the lower temperature during the firing process, the carbon footprint in the production of cement is reduced.”

Benelux: Belgium-based building supplies chain EcoBati has signed a distribution agreement with France-based Hoffmann Green Cement Technologies. The producer will supply its H-Iona clinker-free cement for EcoBati to sell online and in its shops in Belgium, Luxembourg and the Netherlands.

Hoffmann Green Cement Technologies owners Julien Blanchard and David Hoffmann said "Signing a distribution agreement with an international specialist in ecological materials shows the competitive edge and relevance of our H-Iona cement within the context of the fight against global warming. We are therefore delighted with the signing of this partnership that allows us to benefit from the EcoBati network’s strategic retail outlets and provide a response to the exponential demand for sustainable cement. We intend to sign more such partnerships in the future in order to spread our responsible vision of the construction sector and contribute to the environmental transition."

India: Udaipur Cement Work plans to increase its reliance on renewable power with the installation of a new 4.15MW solar power plant at its cement plant in Udaipur, Rajasthan. When operational, the installation will increase the Udaipur plant’s solar power capacity by 42% to 14.3MW. The producer says that its entire solar power apparatus will facilitate a reduction in CO2 emissions of 14,000t/yr. In the 2020 and 2021 financial years, the producer consumed 13,000MWh of solar power, reducing CO2 emissions by 10,000t.

UK: The Mineral Products Association (MPA) has announced the successful completion of a trial of cement production using a net-zero fuel mix consisting of hydrogen and refuse-derived fuel (RDF) at Hanson’s Ribblesdale, Lancashire, cement plant. The RDF in the mix consists of meat and bone meal (MBM) from the food industry and glycerol from biodiesel production.

Increased alternative fuel (AF) substitution is one of seven key levers in the MPA’s Roadmap Beyond Net Zero emissions reduction strategy. The association says that the fuel will eliminate 180,000t/yr of CO₂ emissions from the Ribblesdale plant’s operations when fully implemented. The project received Euro3.71m in government funding.

Hanson’s environmental sustainability manager Iain Walpole said “We are delighted to be involved with this world-leading project, which is a further example of our commitment to cutting CO₂ emissions.” He added “It will also contribute to our ambition of supplying net zero carbon concrete by 2050.”

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.
