China: China Resources Building Materials Technology (CRBMT) subsidiary Tianyang Cement has concluded a ‘full-process intelligent cement plant’ pilot at its 2.81Mt/yr Baise cement plant in Guangxi Province. Tianyang Cement said that the pilot entailed an upgrade that has more than doubled Baise cement plant’s production volumes and reduced its CO₂ emissions per tonne of cement by 24%. Tianyang Cement says that automation has reduced the plant’s unplanned shutdowns by 56% and improved product quality.

Zimbabwe: Lafarge Zimbabwe’s cement volumes fell by 55% year-on-year in the first quarter of 2022. The company restarted grinding units at its Manresa grinding plant in February 2022 following a roof collapse in October 2021. In a trading update, Lafarge Zimbabwe said that the disruption impacted its profit in the quarter. The producer took the opportunity to decommission one of its ball mills for replacement with a new vertical roller mill in mid-2022.

Chief executive officer Geoffrey Ndugwa said “The company is confident that volumes will recover and grow as the availability of cement stabilises, especially after the new vertical roller mill start-up in the second quarter of 2022.”
