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.

France: Hoffmann Green Cement Technologies has inaugurated its pilot plant at Bournezeau, Vendée. The 50,000t/yr unit will manufacture cement products using metakaolin and blast-furnace slag, according to the L'Usine Nouvelle magazine. It says it will produce cement with reduced CO₂ emissions up to 250kg/t using a flash-calcined process down from 900kg/t in the normal clinker production process. The project had investment of Euro10m.

France: Hoffmann Green Cement Technologies’ pilot plant at Bournezeau, Vendée is set to start commercial production of low-carbon cement products in January 2019. Construction of the 50,000t/yr unit is due to be completed in October 2018 with its inauguration scheduled for late November 2018, according to Batiactu. The plant will employ 10 workers initially and this will rise to 15 – 20 as production ramps up.

The producer intends to make cement products using metakaolin and blast-furnace slag. If the pilot plant is a success it then intends to raise funds to build a 0.5Mt/yr plant.
