Chile: Melón has filed an Environmental Impact Statement with the authorities in Santiago for a project to extract pozzolana at a site at Culiprán in Melipilla. The deposit has total reserves of 20Mt and an extraction rate of 0.4Mt/yr is anticipated, according to Minería Chilena. Pozzolana from the site would be used to supply Melón’s cement plants at La Calera and Ventanas

Norway: Germany-based MAN Energy is supplying a compressor system for a carbon capture and storage (CCS) unit being built at Norcem’s Brevik cement plant. The scope of supply includes an RG 63-7 type electrically-powered compressor train. The steam generators cool the CO₂ mixture between the compressor stages and generate steam that is in turn used for capture. The project will be the first to use the ‘Carbon Capture Heat Recovery’ technology (CCWHR) developed by MAN and Aker Carbon Capture. This new process allows the heat emerging from the compressor system to be recovered and used as steam to meet approximately one third of the total heat demand from the Aker Carbon Capture plant. Consequently, MAN says that the system solution demands less energy compared with conventional carbon-capture technologies.

Alexander Sobolyev, Head of Standardisation & Solutions at MAN Energy Solutions, said: "As part of the Norcem project, the digital-twin-based engineering approach of MAN Energy Solutions has led to concrete optimisations. The dynamic process simulation showed that originally planned system components, including heating, valves and additional pipes for safe plant operation, were not required. The time taken for a cold start of the plant can thus be reduced from around 12 hours to 20 minutes – an important characteristic as quick-start capability is always a central criterion for renewable energies."

Zambia: Zambezi Portland Cement is facing fresh legal proceedings over its ownership. The Lusaka Times newspaper reports that proceedings at the Court of Appeal are ongoing against businessman Phesto Musonda. Musonda, a former director of the company, allegedly attempted to take control of part of the company’s plant in September 2021. Unrest has also been reported at the cement producer’s plant with youths throwing stones at workers.

The current owners of Zambezi Portland Cement, the Ventriglia family, previously won a 10-year battle of control of the company against businessman Rajan Mahtani. In 2018 the High Court of Zambia awarded the family full ownership of the business.

Germany: Holcim Germany has published environmental reports for 2020 focused on each of its cement plants. The subsidiary of Switzerland-based Holcim has decided to target its reports on local issues by issuing separate reports for each of its four integrated plants in the country, at Beckum, Höver, Lägerdorf and Dotternhausen respectively. Each report covers national developments for the sector and the company. Local data is then included as well as data on connected cement grinding and concrete plants. The reports can be downloaded from Holcim Germany’s website.

Malawi/Zambia: Huaxin Cement says it has completed its acquisition of Lafarge Zambia and Lafarge Cement Malawi. In late December 2021 the Chinese cement producer completed the equity delivery conditions for Lafarge Cement Malawi. This follows a similar process for Lafarge Zambia in late November 2021.

In June 2021 Huaxin Cement said it had agreed to spend US$150m on purchasing a 75% stake in Lafarge Zambia and US$10m on acquiring Pan African Cement from Lafarge Cement Malawi. The former operates two integrated cement plants in Zambia with a combined production capacity of 1.5Mt/yr. The latter operates a 0.25Mt/yr grinding plant at Blantyre in Malawi. Following the completion of the takeover Huaxin Cement now intends to increase its cement grinding capacity in Malawi by 0.25Mt/yr.
