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.”

Spain: 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. Thus, Cementos Molins aims to achieve an accident-free workplace, to source 55% of its electricity consumption renewably, to increase its alternative fuel (AF) substitution rate to 40% and reduce its cement’s clinker factor to 68%, to halve particulate matter emissions and cut nitrous oxides (NO_x) and sulphur oxides (SO_x) emissions by 40% and 10% respectively and to have signed official agreements with all host communities and employ women in over 23% of management positions.

Chief executive officer Julio Rodríguez said “Sustainability is the cornerstone of our strategy here at Cementos Molins, and today we are delighted to announce the specific targets that we have set out in our 2030 Sustainability Roadmap. The targets and their corresponding action plans - the result of the hard work and dedication of the Cementos Molins team, together with our stakeholders – will help drive our company forward in actively tackling climate change.” He added “We are deeply committed to achieving zero emissions and building a better world for everyone.”

Spain: 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.

China: Hebei province will screen out a total of 1000 existing factories for replacement with less-polluting alternatives under the Chinese government’s 14th Five Year Plan, which covers the period up to the end of 2025. The Xinhua News Agency has reported that factories, including cement plants, will undergo upgrades in order to conform to the plan’s emissions restrictions or close down. The province currently has a total of 233 green factories. Under the 13th Five Year Plan, which concluded in 2020, it reduced its installed cement production capacity by 12Mt/yr.

Germany: 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.”

France: 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.

US: Inhabitants of Ravena, New York, have reported a ‘gritty, sticky, dusty’ residue in areas of the town to mayor Bill Misuraca. The residents described the apparent dust spill as ‘more stubborn to remove’ than on previous occasions.

LafargeHolcim US, which operates the Ravena cement plant in the town, contacted the mayor about the issue, stating “We take all concerns and complains about the plant very seriously and aim to operate in a manner that causes zero harm to employees, contractors, customers, and most of all, local residents, in keeping with our core values.” It added "The plant will be working with the New York Department of Environmental Conservation (DEC) to collect data on the type and source of these materials."
