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.

Guatemala: Cemex has secured its electricity supply for its Guatemalan operations until 2027 through the signing of a renewable power purchase agreement with Enel Green Power. Enel Green Power will supply an estimated 164GWh of renewable energy under the agreement, enabling Cemex to operate one of its Guatemalan cement facilities using 100% renewable energy.

“Transitioning to renewable energy sources is an integral part of our climate action strategy,” said Cemex South, Central America and the Caribbean president Jesús González. “We remain committed to becoming a net-zero CO₂ company and are taking decisive steps to achieve this goal.”

Sweden: HeidelbergCement says that it will establish a 1.8Mt/yr carbon capture and storage (CCS) plant at its Slite cement plant in Gotland. It aims to achieve full-scale capture of the plant’s CO₂ emissions by 2030. In conjunction with the CCS plant project, Cementa will increase the share of biomass in the Slite plant’s fuel mix.

Chair Dominik von Achten said “Just a few days ago, we published new sustainability targets, underlining the importance of carbon capture, utilisation and storage (CCUS) as one key lever to almost halve our CO₂ footprint by 2030 compared to 1990, and achieve Net Zero by 2050 at the latest.” He continued “Slite CCS is the largest CCUS project yet in our group and the cement industry, and a model for what will be achievable with CCUS also beyond 2030. As this initiative contributes considerably to the climate ambitions of Sweden, and is a unique project for us in terms of scale, we are keen to make it happen.”

Germany: Cemex has inaugurated the Carbon Neutral Alliance at its integrated Rüdersdorf cement plant. The initiative is intended to accelerate the development of the site into the world’s first carbon-neutral cement facility by 2030. Jörg Steinbach, Brandenburg’s Minister of the Economy, Fernando A Gonzalez, the chief executive officer of Cemex, the Mexican ambassador to Germany and representatives from Sasol attended the event.

The Carbon Neutral Alliance comprises a network of over 20 private and public organisations, dedicated to industrial decarbonisation. Among the technologies being introduced at Rüdersdorf include a waste heat recovery project scheduled for the summer of 2022, the development of renewable energy generation and a scheme to produce aviation fuel onsite in coordination with Sasol and Enertrag.

In 2020 Cemex announced its decarbonisation target of reducing its CO₂ emissions by 40% by 2030 compared to 1990 levels. This target is expected to be achieved in Europe in 2022. By 2030, Cemex intends to reduce emissions at its European sites by 55%, in line with European Union's new strategy to reduce CO₂ emissions. Cemex has also announced its goal to achieve net-zero carbon emissions in concrete by 2050.

Germany: HeidelbergCement has replaced its existing revolving credit line with a new syndicated credit line based on the Loan Market Association’s sustainability-linked loan principles (SLLP). HeidelbergCement says that key performance indicators of its progress towards sustainability objectives will determine the credit line’s credit margin, adjusted according to its CO₂ emissions per tonne of cementitious material and alternative fuel (AF) substitution rate. HeidelbergCement says that its ‘solid financial base’ enabled it to reduce the syndicated credit line to US$2bn from US$3bn, and to avoid financial covenants.

Chief financial officer René Aldach said “With the conclusion of the new syndicated credit line, we have taken the first step towards sustainable financing. In addition, we were able to improve the terms and conditions compared with the previous credit line.”
