Brazil: Votorantim Cimentos plans to open a limestone grinding plant at Nobres. in Mato Grosso state to produce agricultural lime. The unit will have a production capacity of 0.7Mt/yr, according to the Valor newspaper.

Kenya/South Africa: Kenya’s ARM Cement is fighting moves by minority investors in South Africa’s Mafeking Cement to buy it out for a nominal sum. ARM Cement is attempting to sell its 70% stake in the company for around US$3m as part of its administration process, according to the Business Daily newspaper. Mafeking Cement owns limestone reserves in north-west South Africa and ARM Cement originally took a stake in the company to raise investment and eventually build a cement plant.

However, the minority investors have invoked parts of the shareholders’ agreement and filed a court application in South Africa that, if successful, would allow them buy out ARM Cement’s stake for a nominal price less than US$1. ARM Cement’s administrators PricewaterhouseCoopers have taken steps to counter the move.

Taiwan: Taiwan Cement has reassured the public about the quality and safety standards of its cement and other products. It follows fraud charges being issued to a former government official for supplying raw materials mixed with industrial waste to the cement producer, according to the Taipei Times. Taiwan Cement says it is conducting inspections on all raw materials, including taking random samples of the top and bottom layers of delivery trucks from suppliers.

Lai Chin-kun, a former Hualien County Council speaker, secured local government contracts for his family’s companies to dispose of industrial waste, including industrial byproducts and inorganic debris from electroplating, optoelectronics and display panel manufacturers and pulp paper processing companies. Another family company won a contract with Taiwan Cement in 2010 to supply limestone, clay, sand and other raw materials required for cement production.

Prosecutors allege that when supplying raw materials to Taiwan Cement, Lai instructed company drivers to fill the bottom half of the trucks with industrial waste and place natural materials, such as clay, sand and limestone, on the top half to fool inspectors. Lai reportedly made US$14.1m from the scheme from 2010 to 2015.

Sweden: Cementa’s Skövde plant working on project to optimise its grinding process and reduce the clinker factor of the cement it produces.

Products from the trial are now being tested at a laboratory.
