Germany: Cemex has inaugurated the Carbon Neutral Alliance at its integrated Rüdersdorf cement plant. The initiative is intended to accelerate the development of the site into the world’s first carbon-neutral cement facility by 2030. Jörg Steinbach, Brandenburg’s Minister of the Economy, Fernando A Gonzalez, the chief executive officer of Cemex, the Mexican ambassador to Germany and representatives from Sasol attended the event.

The Carbon Neutral Alliance comprises a network of over 20 private and public organisations, dedicated to industrial decarbonisation. Among the technologies being introduced at Rüdersdorf include a waste heat recovery project scheduled for the summer of 2022, the development of renewable energy generation and a scheme to produce aviation fuel onsite in coordination with Sasol and Enertrag.

In 2020 Cemex announced its decarbonisation target of reducing its CO₂ emissions by 40% by 2030 compared to 1990 levels. This target is expected to be achieved in Europe in 2022. By 2030, Cemex intends to reduce emissions at its European sites by 55%, in line with European Union's new strategy to reduce CO₂ emissions. Cemex has also announced its goal to achieve net-zero carbon emissions in concrete by 2050.

Austria/Canada: Canada-based Solex Thermal Science has been selected by Austria-based Cemtec for a mineral cooling project based in Central Europe. As part of the agreement, Solex will deliver a customised plate-based moving bed heat exchanger (MBHE) that will be used to indirectly cool a milled, mineral-based powder that’s similar to cement. The unit is expected to be delivered by the summer of 2022.

Solex says that the use of a welded plate-channel design allows the powder to flow by gravity within a vertically orientated exchanger and between banks of stainless-steel plates. A heat transfer fluid passes within the plates to cool the material by conduction. The use of indirect heat transfer technology, combined with customised plate spacing, provides the necessary residence time to eliminate caking within the unit while also ensuring consistent temperature profiles at the outlet.

“We are excited to bring our decades of thermal engineering experience to this collaboration with Cemtec,” said Gerald Marinitsch, Global Director, Industrials for Solex Thermal Science. “We are confident that our MBHE technology will provide a reliable, real-world solution to this unique and important cooling application.”

Cemtec is a specialist in providing wet and dry grinding technologies for many types of bulk materials and minerals including the cement sector. Solex Thermal Science develops indirect heat exchange technology for the heating, cooling and drying of free-flowing granular materials such as solid granules, pellets, beans, seeds and particles.

India: Jindal Group has signed a memorandum of understanding with the state government of Chhattisgarh for the establishment of its planned Raigarh cement plant. The Times of India newspaper has reported that the plant will have an integrated capacity of 2.5Mt/yr, in addition to a further 2.5Mt/yr in clinker capacity. It will also operate a 12MW waste heat recovery (WHR) plant.

China: Huaxin Cement has signed a capital injection agreement with Huangshi State-owned Assets Company to acquire a 5.2% stake in the latter for US$150m. The producer says that it will strengthen its cooperation with Huangshi State-owned Assets Company in order to accelerate development of its non-cement business. It said that the transaction will also improve its innovation capabilities, helping it to achieve a low-carbon transformation. Huangshi State-owned Assets Company indirectly owns a 16% share of Huaxin Cement.

China: Anhui Conch Cement has engaged Conch IT Engineering for software platform supply and maintenance services for some of its subsidiaries. The supplier will provide design and technical services for the production process control system software, a sales and product dispatch system, production data uploading and a quality management system for clinker production lines, grinding units, aggregate, commodity concrete and technology modification projects. The value of the work is US$36m.

Vietnam: Vietnam National Cement Association (VNCA) members exported 15.5Mt of cement in the first five months of 2022, down by 14% year-on-year from 16.2Mt in the corresponding period of 2021. The value of the cement and clinker was US$693m, up slightly from US$690m.

In May 2022, Vietnam exported 1.5Mt of cement and clinker, with a value US$92m, down by 52% in volume and up by 29% in value year-on-year.

Canada: Workers at St Mary’s Cement’s Port-Daniel-Gascons cement plant have voted in favour of taking strike action in a dispute over matters including wages and pensions. Local press has reported that workers and the company, a subsidiary of Brazil-based Votorantim Cimentos, will sit in negotiations on 13 and 14 June 2022. Employees previously rejected a ‘final and comprehensive’ offer from the company earlier in May 2022.

Saudi Arabia: Southern Province Cement has completed technical studies and commenced construction of a new 5000t/day line at its Jazan cement plant. The company will also build the infrastructure for another 5000t/day line at the site. Reuters new has reported that, together, the lines will replace the plant’s existing production lines.

Egypt: Misr Beni Suef recorded sales of US$23.5m in the first quarter of 2022, up by 70% year-on-year from US$13.8m in the first quarter of 2021. The producer recorded a net profit of US$2.57m, up by 28% year-on-year from US$2.01m.

Zimbabwe: Lafarge Zimbabwe’s cement volumes fell by 55% year-on-year in the first quarter of 2022. The company restarted grinding units at its Manresa grinding plant in February 2022 following a roof collapse in October 2021. In a trading update, Lafarge Zimbabwe said that the disruption impacted its profit in the quarter. The producer took the opportunity to decommission one of its ball mills for replacement with a new vertical roller mill in mid-2022.

Chief executive officer Geoffrey Ndugwa said “The company is confident that volumes will recover and grow as the availability of cement stabilises, especially after the new vertical roller mill start-up in the second quarter of 2022.”
