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

Flender begins Voerde logistics centre expansion
17 December 2021Germany: Flender has launched the construction of a new 8000m2 storehouse at its Voerde, North Rhine-Westphalia, logistics centre. Along with the lease of an additional building from project developer Panattoni, the project will expand Flender’s total storage footprint by 19,000m2. The supplier says that the new facilities will reduce the Voerde centre’s CO2 by optimising its transport routes.
Flender CEO Andreas Evertz said "I am very happy that the expansion of our site in Voerde will allow us to centralise our logistics activities, bringing us another step closer to our goal of operating in a completely carbon neutral fashion by 2030. With the new warehouse space, we are making our logistics processes sustainable and thus reducing a significant part of the previous transport routes and the associated CO2 emissions.”
ThyssenKrupp to upgrade Ciments Calcia’s Airvault cement plant
07 December 2021France: Germany-based ThyssenKrupp has won a contract for the installation of a new 4000t/day clinker line at Ciments Calcia’s Airvault cement plant in Poitou-Charentes. The supplier expects the new line to double the plant’s clinker capacity while also reducing its CO2 emissions. It is intended to replace the two existing lines at the site.
ThyssenKrupp will supply a 1200t/hr double-shaft hammer crusher, a longitudinal blending bed, a 370t/hr Quadropol QMR² 45/23 type vertical roller mill and a 10,000t tangential blending silo to process raw materials for the line. A single-string, five-stage Dopol type cyclone preheater with integral calciner will be supplied that is suitable to use with alternative fuels, with the possibility of conversion to oxyfuel in future. ThyssenKrupp plans to preassemble the preheater, reducing anticipated construction time ‘by several months.’ The plant also includes a Polytrack clinker cooler, a solid recovered fuel (SRF) preparation line and dedusting systems. Commissioning is scheduled for mid-2024.
No value for the project has been disclosed by Ciments Calcia or ThyssenKrupp. However, Ciments Calcia previously announced a proposed investment of Euro300m in January 2021.
US: The Environment Protection Agency (EPA) has fined Lehigh Cement’s Mason City plant in Iowa US$198,000 for alleged violations of the Clean Air Act. The agency alleges that the company exceeded Clean Air Act emissions limits, failed to submit required reports to the state and failed to conduct required testing of equipment. The EPA also determined that air pollution from the facility may affect nearby overburdened communities. Under the terms of the settlement with the EPA, Lehigh Cement is required to conduct additional air emissions testing to demonstrate ongoing compliance with the Clean Air Act.
