Górażdże Cement to invest Euro261m in carbon capture and waste concrete recycling at Górażdże cement plant
05 October 2023Poland: Górażdże Cement has announced an investment of Euro261m in planned sustainability upgrades to its Górażdże cement plant in Opole Voivodeship, the Polish News Bulletin newspaper has reported. The Heidelberg Materials subsidiary plans to build a carbon capture installation, a green energy source and a facility to recycle construction and demolition waste for use in its cement production.
Tarmac and Cambridge Electric Cement participate in trial melt of Cement 2 Zero carbon neutral cement project
03 October 2023UK: The Cement 2 Zero project has successfully concluded its first trial melt of recovered cement paste in an electric arc furnace at the Materials Processing Institute’s Teesside campus. The project uses the paste as flux for electric steel recycling. Cambridge Electric Cement (CEC) has demonstrated that the ‘slag’ from this process can be ground into fine clinker that, when mixed with gypsum and supplementary cementitious materials (SCMs), produces net zero CO2 cement. The Cement 2 Zero project to produce CEC’s cement at an industrial scale launched in March 2023, with US$7.85m in funding from UK Research and Innovation. Tarmac will grind the clinker from the project’s trial melts for testing in order to obtain certification and specification as a usable cement product.
UAE: Cemex UAE and UltraTech Cement UAE have signed an agreement to collaborate on the development of waste concrete recycling in the UAE, according to Dow Jones Institutional News. The cement producers say that their partnership will help to reduce CO2 emissions from construction, in line with the UAE’s 2050 net zero commitment.
EU: The EU launched the transitional phase of its carbon border adjustment mechanism (CBAM) on 1 October 2023. Parties that import cement - and five other commodities - into the EU must now show the embodied CO2 emissions of their products.
The transition comes ahead of the full implementation of the CBAM in January 2026. At this point, those importing cement into the region will have to pay for the embodied CO2 of their products in order for them to enter the EU Common Market. Producers within the EU already pay for a proportion of emissions under the auspices of the EU Emissions Trading Scheme (ETS).
The intention of the CBAM is to reduce the risk of 'carbon leakage' as the costs of making cement rise in the EU due to changes in the ETS. While cement producers, as heavy CO2 emitters, are currently shielded from the full cost of their emissions, the number of free allowances they receive is set to fall substantially by 2026. At the same time, the cost of emitting a tonne of CO2 under the ETS, currently Euro80-90/t on the open market, is widely expected to rise.
India: JSW Cement is conducting a pilot project in the use of electric vehicles for cement transportation. The producer has introduced five Murugappa electric cement trucks into its fleet in Andhra Pradesh and Karnataka. It expects these to eliminate 150t/yr of CO2 emissions from its logistics operations.
Daijiworld News has reported that CEO Nilesh Narwekar said “The pilot project is an important milestone in making our future much greener and more purposeful.” He added “Based on the success of these pilot trials, we will scale-up the integration of these trucks across our cement operations in India.”
Honduras: Cementos Argos Honduras has commissioned a 1.6GWh/yr solar power plant at its Choloma grinding plant in Río Blanquito. Grupo Argos’ energy subsidiary Celsia built the plant, which consists of 2160 photovoltaic modules. The La República newspaper has reported that the installation cost US$1.2m. It will supply 25% of the Choloma grinding plant’s energy consumption, and reduce its total CO2 emissions by 23%.
Cementos Argos Honduras CEO Luis Eduardo Tovar said "This partnership marks a significant milestone in our efforts to address climate change and revitalise our ecosystems, while generating significant impact in communities with new employment and investment opportunities.”
Cemex achieves environmental impact labelling coverage across main products in its most important markets
21 September 2023Mexico: Cemex said that it has successfully implemented labelling showing the environmental impacts of all of its main products across its ‘most important markets.’ Depending on prevailing practices in each market, products’ packaging either displays an Environmental Product Declaration (EPD) or Cemex’s own third-party validated CERO2 designation.
General director Fernando González Olivieri said “We are committed to being the leading partner in sustainable construction for our clients. In this way, our clients have environmental impact information that they can use to develop sustainable construction.” He added “We continue to expand our portfolio of sustainable products, allowing our clients to effectively design and manage the carbon footprint of their construction projects.”
James Whitelaw to head Hanson UK’s new recycling line
20 September 2023UK: James Whitelaw will take on the role of managing director in Hanson UK’s newly-established recycling business line. He will be responsible for identifying opportunities to grow organically using the company’s existing capabilities and for integrating new acquisitions.
Whitelaw has held management roles in Hanson UK since 2001 and most recently served as aggregates managing director.

Coolbrook completes RotoDynamic Heater pilot test
20 September 2023Netherlands: Finland-based Coolbrook has completed the first test phase of the large-scale pilot of its RotoDynamic Heater (RDH) at the Brightlands Chemelot Campus in Geleen, Netherlands. The engineering company says that this has validated the RDH’s technical pathway up to industrial heat generation at temperatures suitable for cement plants. By developing and launching the technology, Coolbrook says that it will rely on a ‘comprehensive partnership ecosystem,’ including market leaders in technology and industry. It says that the RDH has the potential to eliminate 2.4Bnt/yr of CO2 emissions – 30% of global industrial CO2 emissions and 7% of all global CO2 emissions.
CEO Joonas Rauramo said “Sharing our partners’ and customers’ sense of urgency to achieve net zero, we take determined actions to execute our strategy and progress towards the commercial launch of our electric technology. We are proceeding with first commercial agreements, while continuing to build our organisation and supply chain for industrial scale operations.”
Holcim invests in Neustark
20 September 2023Switzerland: Holcim has invested in CO2 mineralisation technology developer Neustark. Neustark aims to remove 1Mt of atmospheric CO2 by 2030 and sequester it in recycled construction and demolition waste. The company’s technology achieved Gold Standard certification as a method of CO2 removal in March 2022. Holcim says that its investment advances its group commitment to putting clean technologies to work towards achieving net zero.
Holcim’s Europe regional head Miljan Gutovic said "At Holcim, we are working to decarbonise building for a net zero future, and Neustark's technology helps us reach this goal. After the successful demonstration of Neustark's solution in Switzerland, we are ready to scale up this carbon removal technology globally."
