Canada: Heidelberg Materials says that its integrated Delta cement plant in British Columbia has switched to exclusively producing its EcoCem Portland limestone cement (PLC). EcoCem PLC is a Portland limestone cement that contains up to 15% limestone and generates approximately 10% less CO₂ compared to other Portland cements. It has equivalent performance to ASTM and CSA standards for Type I/II Portland cement in strength and durability, and can be used in any application where Portland cement Type I is normally used.

Prior to the full transition to PLC production, the plant had already taken steps to reduce its CO2 emissions by using alternative fuels. The Delta cement plant has been in operation since the 1970s.

US: The United States Geological Survey has reported that the US consumed 40.5Mt-worth of cement shipments in the first five months of 2023. This corresponds to a 4.3% year-on-year fall from five-month 2022 volumes of 41.5Mt. Blended cement, primarily Type IL Portland limestone cement (PLC), accounted for 37% of shipments, compared to 16% in the corresponding period of 2022. Total demand rose by 4.3% year-on-year and by 19% month-on-month to 10.2Mt in May 2023. Imports of cement and clinker totalled 10.5Mt. The leading source of imported cement and clinker were Türkiye, which supplied 3.34Mt (32%), Canada, which supplied 1.58Mt (15%), and Vietnam, which supplied 1.3Mt (13%).

US production of clinker dropped by 2.1% to 29.5Mt in the first five months of 2023, from 30.1Mt a year earlier.

Nigeria: Lafarge Africa has applied to the Standards Organisation of Nigeria (SON) to use the product name Roadcem for its CEM-II Portland limestone cement (PLC) when sold in bulk. The Nigeria Tribune newspaper has reported that Lafarge Africa supplies PLC in bulk for use as a soil stabiliser in roadbuilding. It sells supplies the product bagged to retailers as Classic PLC.

SON certified Lafarge Africa's PLC under its Mandatory Conformity Assessment Programme.

US: Heidelberg Materials North America inaugurated its 2.4Mt/yr Mitchell cement plant in Indiana on 14 July 2023. The plant is equipped with a 3600 bag/hr rotary packer, and also boasts a 154,000t-capacity clinker storage dome. It will produce Heidelberg Materials North America's EcoCem Portland limestone cement (PLC), alongside other products. The producer said that the new plant will help to address US cement supply chain constraints amid a planned US$110bn infrastructure overhaul.

Heidelberg Materials North America president and chief executive officer Chris Ward said "The plant will reduce CO₂ emissions per tonne of clinker by almost 30%, mainly through operating on natural gas. Our investment in the Mitchell facility helps us lower our carbon footprint, while serving the growing demand for more sustainable products in this key market.”

Philippines: Holcim Philippines introduced Holcim Optima, a blended Portland limestone cement (PLC), on the Philippine market on 8 June 2023. The Business Mirror newspaper has reported that Holcim Optima cement offers 10% reduced CO₂ emissions compared to ordinary Portland cement (OPC).

President and CEO Horia Adrian said that Holcim Optima cement 'delivers the same strength, workability and durability as OPC and remains compatible with other cement additives such as slag and fly ash. The new product is best used in large building projects and available in bulk.' Adrian added "It is a timely product for the Philippines, as infrastructure building accelerates and green demand grows."

US: Eagle Materials reported sales of US$2.1bn in 2022, up by 15% year-on-year from 2021 levels. The producer's earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 19% to US$782m. Its cement sales rose by 7% to US$1.1bn due to increased prices, despite a drop in volumes. Throughout the year, the company increased its production of Portland limestone cement (PLC).

President and CEO Michael Haack said "Looking ahead, we anticipate continued attractive fundamentals in our markets, despite headwinds relating to higher interest rates and affordability constraints in single-family residential construction. Among the favourable demand factors we expect will affect our results in future periods are projected funding increases for infrastructure projects and healthy demand for heavy industrial projects and multi-family residential construction. We remain well-positioned to capitalise on these conditions, given our geographical footprint across the (Central) US Heartland and fast-growing Sun Belt (Southern US) and our financial strength and flexibility."

Portugal: The first batch of clinker has been manufactured on the new upgraded production line at Secil’s Outão plant. Construction and start-up teams from ThyssenKrupp Polysius reached the milestone in mid-April 2023 after a heating period of 72 hours. Germany-based ThyssenKrupp Industrial Solutions was appointed by Secil to work on the Clean Cement Line project in 2020. It said it was going to modify the existing rotary kiln and preheater tower, install a new calciner and add a new grate cooler. Once finished it will produce Portland limestone cement (PLC). It is scheduled for commissioning in mid-2023.

Italy-based CTP Team was contracted in mid-2020 to supply and install a 29MW waste heat recovery (WHR) unit for the project. It planned to use an organic rankine cycle (ORC) unit using a 7.2MW turbine supplied by Turboden.

Italy-based Bedeschi also revealed in early April 2023 that it was in the cold commissioning phase for a new pipe conveyor at the plant to handle different kinds of alternative fuels. The conveyor has a diameter of 250mm and conveying length of 350m and will transport alternative fuels at a rate of 300m³/hr.

Greece: Titan Cement Group’s sales rose by 33% year-on-year to Euro2.28bn in 2022, while its earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 20% to Euro331m. The producer sold 17.2Mt of cement, up by 2% year-on-year from 16.8Mt. Its USA sales rose by 34% to Euro1.31bn, its Southeastern Europe sales rose by 33% to Euro386m, its Greece and Western Europe sales rose by 22% to Euro326m, its Eastern Mediterranean sales rose by 48% to Euro256m and its Brazil-based joint venture Apodi’s sales rose by 38% to Euro115.9m. During the year, the group commenced exports of Type IL Portland limestone cement (PLC) from its Samsun, Türkiye, cement terminal to the US.

Group chair Marcel Cobuz said “The great performance results highlight the group's ability to adapt to market conditions and to activate effective growth strategies, driving positive financial performance mainly in US and Europe, where we serve the majority of our customers and have close to 90% of our sales. They also underscore the group’s resilience, adaptability and commitment of all our great teams to transform the group commercially and technologically while digitising our customer journey and decarbonising aggressively, delivering long-term value to all our stakeholders.”

Portugal: Secil says that it will commission its Outão cement plant's new line, called a Clean Cement Line, in mid-2023. The line will produce Portland limestone cement (PLC).

Jornal de Negócios News has reported that this will increase the producer's consumption of limestone, for which its already partly relies on imports. Secil has submitted an application to expand its limestone mines, entitled New Quarry Plan, to the Portuguese Environment Agency. Under the plan, Secil will connect it Vale de Mós A and Vale de Mós B quarries. It will thereby secure sufficient supply to become entirely reliant on mined limestone in its cement production. The plans also leave a 27 hectare 'plateau' at the site, which will be available for other uses.

Italy: Holcim announced its acquisition of Nicem, Italy's ground calcium carbonate market leader. The group said that it plans to use Nicem's ground calcium carbonate as raw material in production of its ECOPact and ECOPlanet reduced-CO₂ cement and concrete range.

Holcim's Europe regional head Miljan Gutovic said “Nicem complements our existing operations perfectly and allows us to further leverage our expertise in green formulation, opening a new source of alternative materials to decarbonise our ready-mix concrete. I look forward to welcoming the employees of Nicem to the Holcim family, whose valuable expertise will help us accelerate green growth.”
