Nigeria: Finland-based Wärtsilä has secured a contract to supply a 70MW dual-fuel power plant for the upcoming 3Mt/yr Line 4 of its Sokoto cement plant. The power plant is scheduled for commissioning alongside the line before 2023. BUA Cement previously ordered a dual fuel plant for the Sokoto cement plant’s Line 3, which is also scheduled for commissioning alongside that line, in November 2021.

Chair Abdul Samad Rabiu said “BUA Cement is happy and pleased with the progress that Wartsila made with the construction of the power plant we initially purchased for our BUA Cement Sokoto Line 3. We believe Wärtsilä will bring the same level of efficiency, technical expertise and professionalism to bear in ensuring that this new power plant for the 3Mt/yr BUA Cement Sokoto Line 4 will be completed on schedule by the end of 2022 as we look towards bringing BUA’s total capacity in its Sokoto plant to 8Mt/yr by early 2023 and across all its plants to 17Mt/yr by the same time.”

India: The total new waste heat recovery (WHR) unit capacity of cement producers is expected to reach 175MW in the two years ending on 31 March 2022. Rating agency ICRA has valued the total investment in new WHR units over the period as up to US$230m, according to the Press Trust of India. A market report by ICRA reports that power generation using WHR costs around US$0.02/kWh compared to US$0.7/kWh from a captive coal power plant. Cement companies that replace 25% of total power capacity with WHR can potentially save around 15% from existing power costs.

Paraguay: Cartes Group subsidiary Cementos Concepción says that construction of its San Lázaro, Concepción, cement plant is 70% complete and on track for a commissioning date in August 2022. The La Nación newspaper has reported that the total investment value of the project is US$200m. President José Ortiz said that two issues had been overcome in staying on schedule, namely the Covid-19 outbreak and low flow of the river on which the new plant will be situated, both of which presented logistical problems. Work also continues on the establishment of a dedicated power plant for the plant at Vallemí.

Mozambique: Chinese West International Holding subsidiary Dugongo Cement has inaugurated its 2.0Mt/yr integrated Matutuine cement plant in Maputo province. The unit had an investment of US$330m, according to the Mozambique News Agency. The site includes a captive 36MW charcoal-fired power station and a residential complex for some of its 300 permanent staff.

President Filipe Nyusi said, “The Dugongo Cement plant will improve the economy of the cement industry, because it will reduce the import of inputs such as clinker."

India: The cement sector’s consumption of fly ash has reportedly collapsed since March 2020. The Financial Express newspaper has reported that the sector previously used over 25% of the ash from coal-fired power plants. The Association of Power Producers says that the suspension of cement production during coronavirus lockdown prevented the more of the country’s coal plants than usual from reaching the required 100% utilisation (for plants over three years old) in the 2021 financial year. In the 2020 financial year, 47 of 101 plants utilised 100% of their fly ash. Other uses beside cement production include brick and tile production, roadbuilding and land reclamation.

US: Energy company Luminant has awarded Charah Solutions a fly ash management contract extension for its Miami Fort and Zimmer coal-fired power plants in North Bend and Moscow, Ohio. Charah Solutions says that it will pass on the ash for use in concrete production. It will continue to manage the onsite landfill and impoundment operations under its existing contract with Luminant, including material loading, hauling and disposal of approximately 180,000t/yr. In addition, Charah Solutions will be responsible for the beneficiation and utilisation of approximately 400,000t/yr of fly ash. The contract ends in 2027, when both power plants are expected to close.

President and chief executive officer Scott Sewell said “We have been proud to partner with Luminant on its sustainability efforts for many years and are delighted to extend our relationship at these Ohio sites through 2027. We have dramatically reduced the need to landfill fly ash at Miami Fort and Zimmer through our on-going partnership, saving Luminant both expense and valuable landfill space while lowering their risk.” He added “As a result of this expanded agreement, Charah Solutions will continue to provide a reliable supply of high-quality fly ash to ready mix concrete producers in the Midwest, Northeast and deep South through our MultiSource network.”

US: Salt River Materials subsidiary Phoenix Cement Plant is working with ST Equipment & Technology (STET) on a fly ash separation system at a power plant in Utah. The cement producer previously secured a contract with a power plant in the state for the supply of fly ash to its Clarkdale cement plant in Yavapai county, Arizona. STET is supplying the separation equipment, engineering and commissioning services, and an exclusive technology operating license for Salt River Materials. Operations are schedule to start in mid-2021.

Pozzolan business senior vice president Dale Diulus said "Salt River Materials and STET have been working closely to develop a commercially effective beneficiation process improving the quality of the fly ash." He added "We look forward to many years of fly ash sales into the southwestern US markets."

Nigeria: Dangote Cement has recorded sales of US$2.52bn in 2020, up by 16% year-on-year from US$2.18bn in 2019. Earnings before interest, taxation, depreciation and amortisation (EBITDA) increased by 21% to US$1.17bn from US$965m. Total cement sales volumes rose by 8% to 25.7Mt from 23.7Mt and Nigerian cement sales rose by 13% to 15.9Mt from 14.1Mt. Highlights for the year included the start of clinker exports from the Apapa terminal and the commissioning of the Onne cement terminal in Nigeria. The group also commissioned a gas power plant in Tanzania.

Chief executive officer Michel Puchercos said, “Despite the impact of the Covid-19 pandemic, 2020 was a record year for Dangote Cement across the board. Several firsts made 2020 a productive year such as our maiden clinker shipment, maiden bond issuance and successful buyback programme. We increased our capacity by 3Mt/yr in Nigeria, commissioned our two export terminals and commissioned our gas power plant in Tanzania. All this was achieved whilst we focused on protecting our people, customers, and communities from the impact of the pandemic.”

Indonesia: Semen Baturaja has signed a memorandum of understanding with Huadian Buket Asam Power. Under the agreement, the producer will supply the power company with limestone for its flue gas desulfurisation (FGD) process in exchange for fly ash, bottom ash and gypsum. The agreement will last two years until March 2023.

The cement producer’s managing director Sumsal Saifudin said, “This collaboration is a form of synergy between the two companies to improve competitiveness, which is much-needed in facing an increasingly competitive industrial environment, by taking advantage of opportunities for the creation of new revenue streams and cost transformation.”

Oman: Oman Cement has issued an engineering, procurement and construction (EPC) tender to build a power plant at its proposed integrated plant at the Port of Duqm. The Muscat Daily newspaper has reported that the plant will have a clinker production capacity of 5000t/day and is expected to cost US$250m.
