Finland: The VTT Technical Research Centre of Finland and Finnsementti have revealed work on the Decarbonate project to test a 12m electrically-heated rotary kiln. Other partners on the initiative included Nordkalk and UPM. Precalcination was tested as well as the projection of quick lime. The eventual goal is to use electricity from renewable sources to power the kiln and then capture the CO₂ released for utilisation.

The Decarbonate project has been exploring CO₂ capture and utilisation concepts that can be commercialised. It has run for two years since late 2019 and has funding of Euro1.2m. It has also looked at oxyfuel and electrolysis experiments.

Poland: Cemex Poland has established a new 50kW solar power plant at its Pruszków ready-mix concrete production plant in Masovian Voivodeship. The company says that it is planning other investments to retrofit renewable energy systems into its operations across Poland.

Materials director Michał Grys said “Cemex is actively addressing the climate challenge by decarbonising our processes. The key to realising our ambitious goals is finding and implementing new low-emission products as well as more sustainable technologies and construction solutions.” He added “Photovoltaic farms are another investment by Cemex Poland in renewable energy sources. Currently, much of the electricity used in our aggregate quarries, cement plants and many concrete plants comes from renewable sources."

Mexico: Cemex has received validation from the Science-Based Targets Initiative (SBTi) for its 2030 global CO₂ emissions reduction targets. The validation attests that the targets conform with the Paris Agreement’s well-below 2°C global warming limit. Under its Future in Action programme, Cemex aims to reduce its cement’s carbon footprint to 40% compared to 1990 levels and achieve 55% renewable energy use by 2030. The company says that it has the global cement industry’s most ambitious 2030 targets.

CEO Fernando Gonzalez said “Climate action is the biggest challenge of our times. Cemex is taking decisive action to address it by defining ambitious emissions reduction targets in line with the SBTi, and executing against those targets.” He added “We commit to continue leading the industry in climate action not only because it creates value, but more importantly because it is the right thing to do. Cemex is building a better future, and that future must be sustainable.”

India: Udaipur Cement Work plans to increase its reliance on renewable power with the installation of a new 4.15MW solar power plant at its cement plant in Udaipur, Rajasthan. When operational, the installation will increase the Udaipur plant’s solar power capacity by 42% to 14.3MW. The producer says that its entire solar power apparatus will facilitate a reduction in CO2 emissions of 14,000t/yr. In the 2020 and 2021 financial years, the producer consumed 13,000MWh of solar power, reducing CO2 emissions by 10,000t.

India: UltraTech has made a commitment to transition to 100% renewable energy use by 2050. The Aditya Birla subsidiary has joined the global RE100 group of companies committed to energy decarbonisation. Asian News International has reported that the producer is already targeting 34% renewable energy use by 2024 from 13% in 2020. It more than doubled its consumption of renewable energy between 2018 and 2020. UltraTech Cement is additionally targeting a CO2 emissions reduction to 462kg/t of cement. It is the first Indian producer to instigate sustainability target-linked financial commitments.

Pakistan: DG Khan has connected its upgraded Hub cement plant and power infrastructure to the national grid. The Pakistan Observer newspaper has reported that the facilities generate 40MW of power via a 10MW waste heat recovery (WHR) plant and 30MW coal-fired power plant. China National Building Material (CNBM) subsidiary Sinoma Energy Conservation provided engineering, procurement and construction (EPC) services for both power plants.

Turkey: Builders have declared a one-day ‘strike’ on 2 September 2021 to protest against high cement prices. The Turkish Builders Confederation (IMKON) told the government that, though the prices of all commodities rose following the onset of the Covid-19 pandemic, the cement price rise is disproportionate, according to the Dünya newspaper. Producers responded that they have recorded sharp increases in input prices. Electricity costs rose by 64% year-on-year in July 2021, while coal costs more than doubled over the same period.

Spain: Construction work has started on 6.2MW solar plant that will supply electricity to Cementos Cosmos’ Toral de los Vados integrated plant in León. Commissioning is scheduled by February 2022. The photovoltaic plant will include over 11,400 solar panels in an area of around 10 hectares. It will meet 15% of the plant’s electricity demands. Spain-based solar specialist EIDF (Energía, Innovación y Desarrollo Fotovoltaico) is supplying the unit at a previously reported cost of Euro4m.

Iran: Alireza Razm Hosseini, the Minister of Industry, Mine and Trade, says that the government will prioritise electricity supplies to the cement and steel sectors. He admitted that recent power rationing to industrial users had reduced production levels but that demand had not changed, according to the Islamic Republic News Agency (IRNA). The ministry is currently working with the Ministry of Energy to resolve the problem. Cement and steel producers were previously ordered in early July 2021 to stop production for up to three weeks due to insufficient electricity supplies.

Iran: Cement and steel producers have been ordered to stop production for up to three weeks due to insufficient electricity supplies. A spokesman for the electricity industry said that the cut in supply was now necessary after heavy industrial customers had failed to observer a voluntary request, according to the Fars News Agency. Electricity supplies will be reduced to 10% of normal levels during the period.
