Nepal: The Nepal Electricity Authority (NEA) has agreed to supply ten industrial users, including cement producers, with an additional 151MW of electricity as part of a drive to increase domestic consumption. The cement producers concerned include Maruti Cement, Huaxin Cement, Hongshi Shivam Cement and Arghakhanchi Cement, according to the Republica newspaper. The other industrial users are mostly steel producers. In addition another 111MW is in the final stages of being allocated by the NEA to seven other industrial plants and a further 99MW has been identified for further distribution to industrial users. The government-supervised power supplier and distributor has identified around 500MW of wasted electricity supply due to low domestic consumption and a lack of transmission lines.

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.
