Cement sector CO2 emissions double in 20 years
23 June 2022World: The total volume of CO2 emissions released during cement production have more than doubled over the past 20 years, a study has revealed. In 2021 CO2 emissions from the manufacture of cement came to 2.6Bnt, more than 7% of all emissions, according to Robbie Andrew, a greenhouse gas emissions scientist at the CICERO Center for Climate Research in Norway and the Global Carbon Project. In 2001 the CO2 emissions from cement production were just 1.2Bnt.
Driven by China, the global cement sector’s CO2 emissions have now more than tripled in the 30 years since 1992, recently increasing by 2.6% a year. The drivers are not just that more cement is being made, but that the CO2 intensity of production has risen by 9.2% per tonne, according to the International Energy Agency. This is due to a switch from production in mature markets to developing ones, with China again a dominant factor.
Fauji Cement’s sustainability initiatives slash 215,000t of CO2 emissions in 2022 financial year
20 June 2022Pakistan: Fauji Cement says that its sustainability initiatives across its three cement plants reduced CO2 emissions by 215,000t in the 2022 financial year. The Pakistan Today newspaper has reported that clinker factor reduction in reduced-CO2 products such as Askari Green cement and Pamir cement eliminated 89,900t-worth of emissions, 42% of total reductions. Waste heat recovery (WHR) plants eliminated 79,400t of emissions (37%), solar power plants eliminated 31,500t (15%), alternative fuel (AF) substitution eliminated 8030t (3.5%) and reforestation eliminated 600t (2.5%).
Ciments Calcia to increase rail transport
09 June 2022Belgium/France: Ciments Calcia plans to transition 60% of its truck transport of cement in Belgium and France to rail. The company says that the shift will eliminate 5% of its CO2 emissions. 400 rail cars currently distribute cement from Ciments Calcia’s 10 production sites. The producer said that the planned increase became possible due to logistics solutions developer Everysens’ transport digitisation software.
US: The US Department of Energy has granted Solidia Technologies US$2.1m in funding for the development and testing of carbonation methods for its Solidia Cement. Solidia will research synthetic supplementary cementitious materials (SCMs) production methods using direct CO2 capture and utilisation.
CEO Russell Hill said “We are proud to partner with the US Department of Energy to continue innovating and ultimately deliver on our mission to provide commercially viable decarbonisation technologies and sustainable solutions for the global construction and building materials industries. The funding will advance our carbon capture, utilisation and storage (CCUS) technologies and synthetic SCMs that can be easily integrated into Portland cement-based concrete formulations, offering manufacturers a solution that is sustainable environmentally and economically.”
Mannok’s sales rise in 2021
16 May 2022UK: Mannok recorded sales of Euro270m in 2021, up by 16% year-on-year from Euro233m in 2020. The company’s earnings before interest, taxation, depreciation and amortisation (EBITDA) fell by 17% to Euro25.8m from Euro31.1m. The group attributed this to substantial cost absorption beginning in mid-2021. Energy prices rose by 66% year-on-year, while the cost of carbon emissions trading scheme (ETS) credits more than doubled to Euro80/t at the end of the year.
Mannok said that demand for its products remains resilient, supported by stronger cost recovery. It added that a levelling out in energy prices has driven stronger profitability in the first quarter and April of 2022.
Switzerland: Jura Cement has commissioned a regenerative thermal oxidation system at its Wildegg plant. The air pollution control system, supplied by Dürr, was installed to meet anticipated lower gas emission limits for carbon monoxide, hydrocarbons, and ammonia (NH3).
Pakistan: Lucky Cement plans to install a 34MW solar power plant at its Pezu power plant in Khyber Pakhtunkhwa. The Balochistan Times newspaper has reported that the 48GWh/yr installation will be equipped with a 5.59MWh Reflex energy storage system. Both the power plant and energy system will be the country’s largest when commissioned. Fossil fuel generation will remain online, but be shut down in the daytime, saving 26,600t/yr of CO2 emissions.
Germany: Rohrdorfer and Austria-based Andritz Group are in the process of installing a 2t/day CO2 separation plant on the roof of the former’s Rohrdorf cement plant in Bavaria. The pilot plant will capture CO2 from the plant’s emissions for use by the regional chemicals industry. The Ingenieur newspaper has reported that it will cost Euro3m and is scheduled for commissioning before June 2022. It is the first installation of its kind at a German cement plant.
Rohrdorfer’s plant and process engineering manager Helmut Leibinger said “We must begin to see CO2 as a product of value rather than a problem. With CO2 as a carbon source, Germany can protect the climate and at the same time become less dependent on oil and natural gas. In addition, value creation and jobs will remain in the country.”
Cementos Molins targets 20% CO2 emissions reduction by 2030
16 February 2022Spain: Cementos Molins has committed to a 20% reduction in its CO2 emissions between 2020 and 2030. The company has set out its strategy in its 2030 Sustainability Roadmap. The roadmap covers five areas: health and safety, energy and climate change, the circular economy, nature and the environment, and corporate social responsibility.

Catalan court orders closure of LafargeHolcim España’s Montcada i Reixac cement plant
10 February 2022Spain: The Catalonia government has received a court order to close down LafargeHolcim España’s Montcada i Reixac cement plant in Barcelona. The Spanish Collection newspaper has reported that the plant failed to conform to new environmental regulations. LafargeHolcim España has appealed the decision.
The Montcada i Reixac plant currently employs 300 people. A union involved in the issue said that the alleged breach is formal rather than substantive and that an administrative error by the regional government caused the plant to breach the regulations.
