Russia: Eurocement says that its subsidiary Peterburgcement’s Slantsy cement plant in Leningrad Oblast is undergoing an upgrade in order to co-process 100,000t/yr of alternative fuel (AF) in its cement production. The group claims that the upgrade will improve the efficiency of the 1.9Mt/yr plant and reduce its consumption of natural gas by 25%. The purported cost of the upgrade is US$1.77m.

Eurocement previously implemented the same technology at another of its cement plants in the Republic of Mordovia.

US: CalPortland has appointed Hamed Maraghechi as its Director of the Central Research Laboratory. He will be based at the CalPortland Center of Technical Excellence in southern California where he will conduct new research and testing related to issues such as carbon reduction and sequestration to help the company achieve its commitment to lowering greenhouse gases. He will also oversee all advanced analytical services for customers and for internal operations, in this newly created position.

Maraghechi holds a PhD in Civil and Environmental Engineering with a materials focus from the Pennsylvania State University, a master’s degree in Civil and Environmental Engineering from the University of Hawaiʻi at Mānoa and a master’s degree in Polymer Engineering from the University of Tehran in Iran. He was most recently a senior scientist at Fortera working on the design and development of low CO₂ cement and concrete formulations. Prior to Fortera, he worked as a scientist at Boral IP Holdings and the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland.

Turkey: OYAK Cement has detailed its progress towards net zero CO₂ cement production in its Integrated Report 2021. The report's focus is sustainability and digitalisation. Under itsCement 4.0 CO₂ emissions reduction initiative, OYAK Cement has proceeded with efficiency improvements at its cement plants.

OYAK Cement is committed to net zero CO₂ cement production by 2050 and reductions in line with the Paris Agreement to limit global climate change to 1.5°C by 2030.The producer is collaborating withthe Science-Based Targets Initiative (SBTi) to realise its emission reduction goals.

US: The Global Cement and Concrete Association (GCCA) hosted chief executive officers (CEO)from across the global cement industry at its CEO Gathering in Atlanta, Georgia, on 9 June 2022. The event explored the best ways for the sector to progress towards net zero CO₂ emissions. Speakers included: UN special advisor on climate Selwin Hart, US Department of Energy assistant secretary for fossil energy and carbon management in the Brad Crabtree, architecture firm Gensler CEO Diane Hoskins, Chair of Oil and Gas Climate Initiative (OGCI) executive chair Bjorn Otto and climate economist Gernot Wagner.

GCCA CEO Thomas Guillot said “To achieve net zero and enable the delivery of the sustainable built environment of the future, there needs to be ongoing engagement and deeper collaboration between our industry and government in the years ahead. Targeted government policy will be vital to removing barriers and to expediting our industry’s decarbonisation plans.”

Canada: Progressive Planet Solutions has successfully produced a new supplementary cementitious material (SCM) called PozDE from diatomaceous earth. The company says that it developed PozDE using calcium bentonite-containing diatomaceous earth from the Red Lake mine in Kamloops, British Colombia. The SCM’s seven-day and 28-day strength activity index (SAI) values are 101% and 120% those of ordinary Portland cement (OPC) respectively, while its water demand is lower at 98%.

Chief operating officer Ian Grant said “It is uncommon to see SCMs exceed the 7-day strength of the control Portland, so we are excited to see better strength while indicating lower water demand."

Europe: The European cement association Cembureau has expressed its disappointment in the outcome of European Parliament votes on the EU Emissions Trading Scheme (ETS) and Carbon Border Adjustment Mechanism (CBAM). The parliament voted against an amended proposal to introduce a carbon border tax and to phase out ETS allowances from 2028 to 2034, against a previous proposal of 2025 – 2030. Groups including The Greens – European Free Alliance voted against the proposed legislation as they believed it did not go far enough.

Cembureau chief executive officer Koen Coppenholle said “The EU cement industry needs a strong CBAM to support our decarbonisation efforts and fight carbon leakage. Both draft European Parliament texts on ETS and CBAM contain significant improvements on some key issues – such as CBAM’s watertightness or industrial innovation – which are essential to support our transition to carbon neutrality.” Coppenholle continued “We encourage MEPs to resume negotiations as soon as possible and reach a reasonable compromise on the remaining divisive issues, thereby providing a predictable regulatory framework for the industry.”

US: Prometheus Materials has successfully developed cement-free blocks from a material produced by biomineralising cyanobacteria. Dezeen News has reported that the American Society for Testing and Materials (ASTM) has approved the materials for construction applications.

Director Wil V Srubar III said "Coral reefs, shells and even the limestone we use to produce cement today show us that nature has already figured out how to bind minerals together in a strong, clever and efficient way. By working with nature to use existing microalgae to bind minerals and other materials together to create new types of sustainable biocomposite building materials, we can eliminate most, if not all, of the carbon emissions associated with traditional concrete-based building materials."

India: UltraTech Cement has entered into a collaboration with Finland-based Coolbrook to implement the latter’s roto dynamic heater (RDH) electric kiln technology in Indian cement plants. RDH technology uses renewable power to heat kilns to up to 1700°C.

UltraTech Cement managing director Kailash Jhanwar said “UltraTech is a forerunner in utilising renewable energy in its manufacturing operations. We are constantly looking at opportunities to improve process efficiency and reduce greenhouse gas emissions from our operations.” Jhanwar concluded “We believe that our collaboration with Coolbrook will help to further accelerate the decarbonisation of our operations.”

Coolbrook executive chair Ilpo Kuokkanen said “India is one of the most important potential markets for Coolbrook, as we want to make a global impact on CO₂ emission reductions. Cooperation with India’s largest cement producer UltraTech is a significant step in our strategy to decarbonise heavy industry processes globally. UltraTech is also an excellent addition to our comprehensive and responsive partnership ecosystem spanning across leading industrial actors, academic institutions, and the public sector.”

Belgium/France: Ciments Calcia plans to transition 60% of its truck transport of cement in Belgium and France to rail. The company says that the shift will eliminate 5% of its CO₂ emissions. 400 rail cars currently distribute cement from Ciments Calcia’s 10 production sites. The producer said that the planned increase became possible due to logistics solutions developer Everysens’ transport digitisation software.

UK: The UK Department for Business, Energy and Industrial Strategy (BEIS) has granted Carbon Clean Euro701,000 under its Carbon Capture, Utilisation and Storage (CCUS) Innovation 2.0 programme. Carbon Clean says that it will partner with energy engineering company Doosan Babcock and Newcastle University to develop carbon capture systems which apply non-aqueous solvent (NAS) and rotating packed bed (RPB) technology together for the first time. The partners seek to overcome the challenges of scale and cost in order to advance the widespread deployment of CCUS systems.

The CCUS Innovation 2.0 programme is part of the UK government’s Euro1.17bn Net Zero Innovation Portfolio scheme.
