Pakistan: Cement producers in Pakistan sold 44.3Mt of cement in the first 10 months of the 2022 Pakistani financial year, which runs from 1 July 2021 to 30 June 2022, down by 8.2% year-on-year from 48.3Mt in the corresponding period of 2021.Members of the All Pakistan Cement Producers Association (APCMA) record domestic deliveries of 39.5Mt, down by 1.8% from 40.2Mt, and exports of 4.8Mt, down by 40% from 8.02Mt.

The association said that political and economic uncertainty in March 2022 had stalled construction sector investments. It called on the government to help to increase sales and reduce the cost of cement production.

US: The state governments of Arizona, Maryland and Vermont have approved the use of Portland limestone cement (PLC) in public construction projects. The rule changes bring the total number of states in which PLC may be used in this way to 44.

The Portland Cement Association (PCA) has welcomed the decision. The association said "Widespread acceptance of PLC marks a significant step to reducing the carbon footprint of concrete construction and advancing the goals laid out in the PCA Roadmap to Carbon Neutrality."

Mexico: The local government in Santiago de Anaya has revealed that Cementos Fortaleza is planning to build a second production line at its integrated El Palmar plant in Hidalgo. The project is expected to cost US$210m, according to the El Sol de Mexico newspaper. Cementos Fortaleza currently operates a 1Mt/yr plant at the site.

Sweden: UK-based Samson Materials Handling is supplying an Eco Hopper product for installation at the Port of Slite in Gotland. The hopper will be designed to receive clinker, limestone, coal and refuse-derived (RDF) fuel pellets. These materials will be unloaded at the quay area via crane grabs. The hopper will then discharge direct to trucks via a telescopic chute.

The Eco Hopper installation under normal operating conditions and based on the client’s grab sizes and cycle time, will achieve peak discharging rates of: 353t/hr - based on clinker with a bulk density of 1.4 t/m³; 454t/hr - based on limestone with a bulk material density range of 1.8 t/m³; and 420t/hr - based on RDF Pellets with a bulk material density of 0.6 t/m³.

The Eco Hopper product design concept comprises of a specialised reception hopper unit incorporating Integral filter arrangement with a reverse jet filter media cleaning system which returns all material back in to the material stream. In addition, the inlet system of the hopper is based on the Samson Flex-Flap design which reduces the volume of air necessary to control dust both from the opening grab and displaced air from material falling into the inner hopper below. This contributes to the reduction of airflow reducing filter and power requirements of the equipment.

Commissioning and operator training will be provided by Aumund Group Field Services.

Germany: Holcim Deutschland says that the preliminary test phase of a new CO₂ separation unit at its Höver cement plant in Lower Saxony has delivered positive results. Plant manager Stephan Hinrichs said that the company was “delighted” with the results so far. In late 2021 Cool Planet Technologies and Hereon signed a memorandum of understanding with Holcim Deutschland to deliver a carbon capture system for a carbon capture and storage (CCS) trial at the plant based on Hereon’s PolyActive membrane technology.

The next stage of the project will start in August 2022 and it will last until late 2024. This will include a one-year active test phase, in which the system is to be examined in long-term operation, planned to start in September 2023. If the results are good enough then the carbon capture unit will be expanded step-by-step so that after the final expansion stage it can separate around 90% of the CO₂ emissions and deliver high-purity CO₂ in liquid form for sequestration or further use. The ultimate aim of the project is to demonstrate performance, economy and operational behaviour on a larger scale in order to check whether the technology can be used at both Höver and other cement plants. Continued funding for the scheme is dependent on an application to the Competence Centre on Climate Change Mitigation in Energy-Intensive Industries (KEI) as part of the Decarbonisation in Industry program.
