Montenegro: State-owned energy supplier Elektroprivreda Crne Gore (EPCG) has proposed the gradual shutdown of its Pljevlja coal-fired plant and its replacement with a new cement plant. The company said that such a plant would eliminate Montenegro’s 750,000 – 800,000t/yr of cement imports.
The first stage of the Pljevlja power plant’s shutdown will only commence once a replacement power facility is online. Currently, the plant supplies 40% of the country’s energy. Its closure is part of Montenegro’s plan to accede to the EU as soon as 2025.
Mexico: Cemex’s total dispatches of its Vertua reduced-CO2 concrete in Mexico reached 284,000t in 2021. After launching the product in its home country on 8 December 2020, the company supplied it to 3820 sites throughout 2021. Cemex says that it enters 2022 with 1580 orders outstanding.

China: Huaxin Cement and Hunan University have started a pilot production line that uses flue gas from a cement production line to manufacture concrete bricks. The process, being tested at the Huaxin Wuxue Industrial Park in Hubei Province, absorbs CO2 from the flue gas and uses the heat of the gas to cure the bricks, according to the Xinhua News Agency. The average compressive strength of the bricks is above 15MPa. It is estimated that a production line with a brick output of 100m/yr could absorb 26,000t/yr of CO2.
