Portugal: Semapa subsidiary Secil is spending Euro86m on modernising its Outão cement plant in Setúbal. The Dinheiro Vivo has reported that the work will turn the facility into ‘the most sustainable cement plant in Europe,’ according to the company. It will reduce CO2 emissions by 20%, end fossil fuel use and establish waste heat recovery to supply 30% of the plant’s electrical power needs. The government has granted the ‘Project of National Interest’ Euro14.5m in funding. The project will also expand the cement plant’s capacity by 30% to 1.3Mt from 1.0Mt.
Chief executive officer Carlos Abreu said "We have the ambition of reaching carbon neutrality in 2050 and this project is a step in that direction. Others will follow." He added "The Asian and American blocs are not always facing that direction, but the path is made by walking... and we will get there." Regarding the timing of the project, Abreu said "Secil was a very brave company here. The project was decided in 2019 before the pandemic broke out... We kept it, despite the fact that knowing that the pandemic was going to be, and is being, very difficult, but we believe that we had no other alternative."
Cemex to install supercritical CO2 waste heat recovery plant at Prachovice cement plant in the Czech Republic
09 June 2021Czech Republic: Mexico-based Cemex plans to install a 2MW waste heat recovery (WHR) plant using supercritical CO2 (sCO2) at its Prachovice cement plant. The unit is intended to provide up to 8% of the plant’s electricity requirements.
The producer is part of a consortium studying new sCO2 WHR systems. The EU Horizon 2020 Industrial Heat to Power fund awarded Euro14m in financial backing to the consortium. The project is intended to demonstrate a cheaper and more flexible method of waste heat valorisation compared to the steam or organic rankine cycle approaches conventionally used in WHR.
Plant director Karol Czubara said, “The new sCO2 technology has a smaller footprint and higher operational flexibility than conventional power plant cycles, which produce power from turbines using water or steam.”
Pakistan: Bestway Cement has provided details of its upcoming 7200t/day-capacity Paikhel cement plant in Mianwali district, Punjab province. China-based Sinoma International Engineering Company will supply engineering, procurement and construction for the plant. The plant will have a 9MW waste heat recovery (WHR) plant.
India: Penna Cement has filed for an initial public offering (IPO) worth US$212m. It plans to offer US$34m-worth of shares for sale and to issue equity shares worth US$177m. United News of India has reported that part of the money raised will fund capital expenditure (capex) investments worth US$58m. The company’s plans consist of a second line at its Krishnapatnam grinding plant in Andhra Pradesh, an upgrade of raw materials and clinker grinding at its integrated Talaricheruvu plant in Andhra Pradesh, and new waste heat recovery (WHR) units at its Talaricherevu plant and its integrated Tandur plant in Telangana. It additionally plans to repay previous loans.
Switzerland: LafargeHolcim subsidiary Holcim Schweiz’s Eclépens cement plant generated 443,000kWh of energy via its waste heat recovery (WHR) plant in April 2021. The company said that the energy was enough to power 1000 households for the month. The figure brings the plant’s four-month 2021 total energy generation to over 1,000,000kWh. The producer said that the positive trend puts it on course to achieve its annual target of 4,000,000kWh in 2021.
Pakistan: Lucky Cement and China-based China Sinoma Energy Conservation have signed a deal to upgrade the waste heat recovery (WHR) units on both production lines at the integrated Pezu cement plant. When the project is completed it will increase the output to 14MW from 10MW at present. No value for the order has been disclosed. Sinoma supplied the plant’s original WHR units in 2017.
DG Khan Cement returns to profit as sales rise in first nine months of 2021 financial year
27 April 2021Pakistan: DG Khan Cement recorded a consolidated net profit after tax of US$18.5m in the first nine months of the 2021 financial year, compared to a US$12.0m loss in the corresponding period of the 2020 financial year. Net sales rose by 8% year-on-year to US$213m from US$198m. Cement sales volumes fell by 5% to 4.09Mt from 4.32Mt.
The company praised Pakistan’s ‘smart lockdown’ as a mitigating factor of the damaging effects of the coronavirus outbreak. Clinker production was 94% of capacity, compared to 101% in the first nine months of 2020. Total kiln operational days fell by 8% to 813 from 883. Depending on on-going outbreak conditions, the company forecast continued momentum gains in housing and infrastructure. It expects to commission a new waste heat recovery (WHR) power plant in the fourth quarter, reducing costs.
Prism Johnson commissions waste heat recovery plant and solar power plant at Prism cement plant
31 March 2021India: Prism Cement has established a 12MW waste heat recovery (WHR) plant and 10MW solar power plant at its 6.1Mt/yr-capacity integrated Prism cement plant in Satna, Madhya Pradesh. The plant’s total WHR capacity now totals 22MW, with a total of 23MW solar power capacity. The measures are part of the producer’s sustainability initiatives, by which it aims to reduce its reliance on non-renewables.
Cemex Zement establishes Carbon Neutral Alliance to achieve net zero emissions at Rüdersdorf cement plant
18 March 2021Germany: Mexico-based Cemex subsidiary Cemex Zement has set up an innovation acceleration partnership called Carbon Neutral Alliance to support its work to achieve net zero CO2 emissions at its Rüdersdorf cement plant by 2030. The association will work to develop industrial-scale demonstration projects in line with the company’s Future in Action programme. Its scope will include carbon capture and storage (CCS), the transformation of captured CO2 into building materials, synthetic fuels and green hydrocarbons, hydrogen production and waste heat recovery (WHR). Cemex plans to share the knowledge gained by the alliance across its global cement network.
Managing director and Rüdersdorf plant manager Stefan Schmorleiz said, "It is expected that CO2 will be further processed to convert to new forms of energy and materials for use locally by industrial, residential, and transport sectors. Together with our partners, we will take feasibility studies through to economic solutions to decarbonising cement production.”
Ramco Cements plans capacity expansion
15 March 2021India: Ramco Cements says that its 16Mt/yr installed production capacity will increase to 20Mt/yr during its 2022 financial year that starts in April 2021 with the completion of a new plant at Kurnool in Andhra Pradesh and a third production line at its Jayanthipuram plant. The original plan to complete the work by the end of March 2021 was delayed by the coronavirus pandemic, according to the Hindu newspaper. The new integrated plant at Kurnool will have a clinker capacity of 2.25Mt/yr and a cement production capacity of 1Mt/yr. The third production line at the Jayanthipuram plant will have a production capacity of 1.5Mt/yr, increasing the plant’s total to 4.5Mt/yr.
The producer also plans to complete Phase 3 of the installation of a waste heat recover (WHR) unit at the Jayanthipuram plant. Phase 1 (9MW) was commissioned in September 2020, Phase 2 (9MW) in February 2021 and Phase 3 (9MW) is scheduled for after the third line is complete. So far the first two stages have reduced the cement plant’s power consumption from a thermal power plant by 15MW. The project has cost around US$30m.
Ramco Cements has spent US$345m out of its planned US$470m capital expenditure in the 2021 financial year, which ends on 31 March 2021.
