Japan: Taiheiyo Cement has installed three BWZ bucket elevators and a Louise TKF drag chain conveyor supplied by the Hong Kong-based subsidiary of Aumund at its new power plant at Ofunato. The cement producer uses both biomass and coal at the plant.

Two elevators and the drag chain conveyor are used to transport palm kernel shells (PKS) and palm empty fruit bunches (EFB), which are used as alternative fuels in the power plant. Each has a capacity of up to 150t/hr. The conveying concept is designed so that the different materials are kept apart and enter the silo buffer tanks separately. The third bucket elevator is used for coal handling. It is a gravity discharge type BWZ-S elevator with a capacity of up to 35t/hr.

Russia: Siberian Cement Holding Company (SibCem) subsidiary Iskitimcement produced 454,000t of cement in the first half of 2020, up by 7.8% year-on-year from 421,000t in the first half of 2019. Cement shipments over the period were 447,000t, up by 7% from 418,000t.

Iskitimcement said that its CEM-I Ordinary Portland Cement (OPC) was its most in-demand product, constituting 53% of total production at 243,000t. Its new CEM-II Portland slag cement, launched on 28 April 2020, achieved production volumes of 4000t (1%). It said that the coronavirus outbreak caused a slowdown in June 2020, resulting in a 7% year-on-year drop in demand compared with June 2019. Managing director Vladimir Skakun said, “The general weakening of economic activity, the fall in oil prices and the exchange rate of the national currency and a decrease in the incomes of Russians are causing concern.”

The company completed the installation of a closed-circuit dynamic separator and bag filter produced by Germany-based Christian Pfeiffer into the Iskitimcement plant’s grinding unit 6 in June 2020. To date, the equipment has produced 114,000t of ultra-fine cement towards an annual target of 480,000t.

Philippines: Eagle Cement has shared plans for the installation of a fifth mill at its 7.1Mt/yr integrated cement plant in San Ildefonso, Bulacan Province at a cost of US$30m. Business World News has reported that the upgrade will raise the plant’s capacity to 8.6Mt/yr. President and chief executive officer John Paul Ang said, “Our strong financial position will allow us to weather this health crisis battering the economy without giving up major components of our expansion plans.”

Eagle Cement said that it “ramped up production” following the national coronavirus lockdown in June 2020 in order “to support the government’s push for accomplishing critical infrastructure projects.” It is currently working towards the launch of an online customer portal for placing and tracking cement orders.

Argentina: Employees of two companies hired by LafargeHolcim subsidiary Holcim Argentina to carry out maintenance work at its suspended 2.4Mt/yr integrated Malagueño plant in Córdoba Province have taken up residence at the Hotel Uruguay in the resort town of Villa Carlos Paz, causing the hotel to lock down because they did not have the proper certification from the Centro de Operaciones de Emergencias (COE) provincial coronavirus lockdown authority.

The El Diario de Carlos Paz newspaper has reported that the workers, from Olavarría and San Nicolás, Buenos Aires Province, planned to remain locked down in the hotel for fourteen days. Due to their lack of COE certification, Villa Carlos Paz security locked down the hotel while coronavirus tests are carried out. Holcim Argentina manager of corporate affairs Belén Dagher said, “Following our application in June 2020, the COE and the Municipality of Malagueño gave us the authorisation for the arrival of the workers. The companies hired the hotel, and negative coronavirus tests for all workers were sent to the relevant authorities.” He added, “We are making a special space for them to stay at the plant.”

Holcim Argentina is carrying out essential maintenance work on the Malagueño plant, which is scheduled to reopen in mid-to-late 2020.

India: Ambuja Cement has modernised its logistics operations by digitising its supply chain to “improve visibility, deliver quality customer service and optimise cost.” The Economic Times newspaper has reported that the company has integrated all aspects of raw material, fuel and equipment supply and product deliveries on a single online platform in order to “enhance overall efficiency and productivity.” Company director Martin Kriegner said additionally that the digitisation will aid in, “fuel mix optimisation and strategic sourcing, helping to mitigate rising input costs.”

Ambuja Cement’s 3.0Mt/yr greenfield expansion to its integrated 1.5Mt/yr Marwar Munda, Rajasthan plant is scheduled for commission by 1 January 2021. The company has a master supply agreement with ACC aimed at maximising the consistency of cement supply to the Rajasthan market once the new 4.5Mt/yr plant becomes operational.

France: UK-based Carbon8 Systems has announced plans for the commercial implementation of its carbon capture and use (CCU) system at Vicat’s Montalieu integrated cement plant in France. It follows successful demonstration projects at cement plants in the UK and Canada.

The company’s CO₂ntainer product will be deployed directly onsite at the plant and integrated into Vicat's existing industrial processes. It will capture CO₂ directly from the plant's flue gas emissions and use this as part of its Accelerated Carbonisation Technology (ACT) process. This accelerates the carbonation of cement bypass dust into lightweight aggregates. In its first phase of operation it will process and convert up to 12,000t of cement bypass dust.

Tanzania: Huaxin Cement subsidiary African Tanzanian Maweni Limestone has ignited the kiln and begun trial production of clinker at its newly upgraded 0.75Mt/yr Maweni Limestone clinker plant. Huaxin Cement acquired the subsidiary in May 2020 and begun upgrading the kiln line on 1 June 2020, in spite of the fact that only 14 Huaxin Cement management team colleagues remained in the country due to the company withdrawing staff to China prior to the coronavirus lockdown.

Huaxin Cement says that it will not upgrade the plant’s grinding unit “for various reasons.” The company said, “subject to the epidemic prevention and control situation, the company will send an excellent management team to implement advanced cement process technology and management. We are committed to turning Maweni Limestone into a benchmark industrial enterprise in Tanzania and promoting the local cement industry to achieve quality.”

Zimbabwe: PPC Zimbabwe has announced that it has entered into a preliminary agreement with a Zimbabwe-based energy investor “with technical partners in South Africa” that will build and operate the company’s planned 32MW solar power plant in Matabeleland South. 16MW will power PPC Zimbabwe’s cement production and the rest will be fed in the national electricity grid, according to the Herald newspaper. The unit will be located adjacent to PPC Zimbabwe’s 0.5Mt/yr integrated Colleen Bawn plant.

US: Vicat subsidiary National Cement has received a fine of US$148,000 from the Alabama Department of Environmental Management (ADEM) for exceeding mercury emissions regulations over a 123-day period between May 2019 and February 2020 at its integrated Ragland plant in Alabama. The Daily Home newspaper has reported that unexpectedly high mercury levels in coal and other raw materials burned as fuel during that time caused the breach, which the company immediately reported to ADEM.

National Cement president Spencer Weitman said, “The issue took several months to fix.” Multiple upgrades and operational changes solved the issue, including installation of a US$400,000 mercury absorption carbon injection system. ADEM said, “National Cement did not economically benefit from the emissions violations.”

In January 2020 National Cement began work on construction of a new US$250m kiln line, due for completion in 2022.

Pakistan: Power Cement says it has started commercial operation of its new 7700t/day clinker production line at its Nooriabad plant. It completed the procurement and installation of machinery for the new line in mid-2019. It was supplied by Denmark’s FLSmdith.
