India: A shortage of limestone in the Jammu and Kashmir union territory since December 2021 has resulted in cement plant workers being laid off in Udhampur district. The local sector has lobbied the regional government to supply limestone from state-controlled quarries to fix the situation, according to Asian News International. One cement plant employee interviewed by the news agency said that his plant had laid off around 80 workers from a total of 200 due to the shortage.

Tanzania: Tanga Cement’s full-year results show a 9% year-on-year rise in sales to US$99.5m in 2021 from US$91.7m in 2020. Its net profit was US$1.5m, as against a US$903,000 loss in 2020.

The Kenyan Wall Street newspaper has reported that the company replaced a kiln shell at its Tanga cement plant and outsourced mining operations at its quarry during the year.

Switzerland: Environmental activists have occupied a forest on private land next to the Gabenchopf quarry that supplies limestone to Holcim Schweiz’s Siggenthal cement plant. The activists are protesting about a planned expansion to the quarry, according to the Blick newspaper. Police have described the mood of the activists as ‘peaceful.’ The occupation follows a similar protest against expansion of another Holcim-owned quarry at Mormont, Vaud, in 2021.

India: Shiva Cement's board of directors has approved the launch of a shareholders' vote over plans to increase its Odisha cement plant's capacity by 2Mt/yr. The plan also involves the expansion of the same plant's clinker capacity by 3Mt/yr and the installation of a 12MW waste heat recovery (WHR) plant. In addition to this, the company is seeking to open two new limestone mines with a combined capacity of 1.9 - 3.1Mt/yr at Khatkurbahal, also in Odisha. The company has received Ministry of Environment, Forest and Climate Change approval for all of the plans.

US: A court has instructed Continental Cement to pay a worker who acted as an employee representative during Mine Safety and Health Administration (MHSA) inspections at its Hannibal, Missouri, quarry. The Insurance Journal newspaper has reported that the producer reduced the worker's pay as a mobile equipment operator by a total of US$388 over a period of days in March and April 2020. In addition to paying the worker, Continental Cement must pay a US$17,500 fine to the US Treasury for violation of the Mine Safety and Health Act. It is also required to expunge any adverse information related to the whistleblower complaint from the employee's personnel record and to post information on miner's rights in employee areas.

MSHA district manager Robert Simms said "The MSHA investigation found Continental Cement clearly discriminated against the worker for serving as the miners' representative. Federal discrimination laws exist to protect workers from penalties for serving as safety and health representatives while on the job." Simms concluded "The judge's decision sends the message that retaliation is a costly mistake for employers."

Switzerland: Vigier Ciment is operating a self-charging electric dump truck at its limestone and marl quarry in Biel. The 45t truck’s regenerative braking system recharges its 600kwh lithium battery on the downhill trip from the quarry to the primary crusher. Its 65t capacity more than doubles its weight when laden, easily enabling it to recover charge for the return trip. Each trip generates an estimated 10kwh of surplus energy. In ordinary use, this would equate to 77Mwh/yr. It saves 50,000 – 100,000l/yr of diesel and eliminates an estimated 196t/yr of CO₂. Green Car Reports has reported that Kuhn Schweiz built the dump truck, based on Japan-based Komatsu’s HB model truck. It is the world’s largest electric vehicle.

UK: Northern-Ireland-based Cookstown Cement plans to invest around Euro14m on environmental and process upgrades to its integrated 0.45Mt/yr plant in Cookstown. The company is managed and co-owned by David Millar, a sales director with Lafarge, according to the Belfast News Letter newspaper. Holcim announced the sale of its cement business in the region in late January 2022. Cookstown Cement has acquired a cement plant, a limestone quarry in Cookstown, a shale quarry in Dungannon and a terminal at Belfast Harbour.

Croatia: Volunteers from Cemex collaborated with the Agricultural and Veterans’ Cooperative Lintar and local school pupils to harvest 6.5t of olives from the site of its rehabilitated Split quarry in Split-Dalmatia. The company says that the winter crop produced 900l of olive oil.

Cemex’s Europe, Middle East and Africa corporate affairs, sustainability and environmental resources manangement vice president Andrew Spencer said “We recognise that our industry has consequences for the environment, but Cemex is working hard to actively counteract climate change and this drive is present through all aspects of our business. In our cement and aggregate quarrying operations across Europe, we restore and recultivate our sites to provide optimal conditions that are managed well to deliver for biodiversity.” He added “Our vision is of a successful, sustainable Cemex that makes a positive contribution to people and the environment.”
