UK: Cemex UK has invested in a new Canning Conveyor conveyor system at its Swinderby sand and gravel quarry in Lincolnshire. The 1.6km-long system will convey extracted materials to a new processing plant. The new plant will double the quarry’s aggregates production capacity. The system includes a 20t hopper feeder and a radial stockpile, also supplied by Canning Conveyor. The company producer says that the new equipment will cut 50% of the operations’ CO2 emissions by eliminating diesel-powered dumpster use and saving 300,000l/yr of fuel, in line with Cemex’s Future in Action sustainability programme. It will also reduce dust and noise at the quarry. The investment is due for completion in early 2023.

Namibia: Limestone mining hours at Cheetah Cement were reduced by the Ministry of Labour, Industrial Relations and Employment Creation on 19 August 2022. In a notice issued by the ministry, the company was ordered to stop operational activities in its quarry site between 18:00 and 06:00 due to insufficient lighting at the site. The same notice also temporarily suspends the use of forklift machines inside the factory until they are serviced to a satisfactory level.

“The notice is in full force from 19 August 2022 until all corrective measures are effected to the occupational and health safety officers of the ministry,” stated the notice.
Cheetah Cement’s Public Relations O fficer, Tabby Moyo, said that the suspension for overnight mining would not affect the company, as mining during daylight hours provides sufficient raw materials for production, adding that any other irregularities indicated in the notice will be resolved as soon as possible.

This is the second time that Cheetah Cement has been issued a notice by the Ministry of Labour, Industrial Relations and Employment Creation due to non-compliance of labour laws relating to the health and safety of employees. In May 2022, the factory was closed for 11 days when the factory was instructed to rectify issues in its cement mill, packing plant, warehouse and workshop.

Kyrgyzstan: Kant Cement has begun excavating the Severnaya Gryada limestone deposit near to its Kant cement plant.

Kant Cement currently replaces a part of the limestone in the plant’s cement production with 65,000t/yr of fly ash.
