Switzerland: 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."

UK: Hanson UK has launched a recycling business line to process construction and demolition waste. The business will supply recycled materials for use in Hanson UK’s operations.

CEO Simon Willis said “Promoting circularity by recycling, reusing and reducing the use of primary raw materials is crucial to reaching net zero. The development of a separate recycling business line will allow us to provide the most sustainable products to our customers through circularity and innovation, to enable building more with less. It is another significant step towards achieving our aim of being the industry leader in the supply of sustainable, circular products.”

Europe: The Environmental Coalition on Standards (ECOS) has welcomed the EU’s new Empowering Consumers Directive. Under the directive, EU member states must enact laws preventing companies from labelling their products with climate claims based on offsetting. ECOS called the law a ‘significant measure against greenwashing.’ It called on the EU to further ensure that products neither rely on carbon credits, nor on contributions to sustainability projects, in calculating their impacts.

ECOS programme manager Elisa Martellucci said “The EU has taken aim at greenwashing. Climate neutrality claims based only on carbon offsetting are ambiguous and misleading for consumers because they are not linked to concrete efforts to combat the climate crisis. Instead, they rely on flawed carbon accounting practices that ‘write off’ greenhouse gas emissions. The amazing carbon emissions vanishing act is many companies’ dream – but emissions do not magically disappear. Policymakers have taken a strong stance against this deceptive practice.”

Europe: Norway-based Capsol Technologies says that it has signed contracts for two new feasibility studies for carbon capture installations at ‘large cement plants’ in the EU. If successful, the plants will proceed to the installation of Capsol Technologies’ CapsolEoP carbon capture systems. Nordic Daily News has reported that the technology reduces the energy consumption of carbon capture by 50%, and lowers its costs by 25%, according to the supplier.

The new contracts bring Capsol Technologies’ number of cement industry carbon capture contracts to four, and its total contracts to nine, with a potential CO₂ capture capacity of 10Mt/yr.

CEO Jan Kielland said "We are pleased that our solution is gaining attention, as demonstrated by an increasing number of incoming requests for sales engineering and engineering studies, and look forward to being a major contributor in the path to net zero for cement.”

India: Ratings agency ICRA says that the cement industry in India will reach a renewable energy reliance of 40% across its operations in the 2025 financial year. The Hitavada newspaper has reported that this will involve the construction of 537MW-worth of new renewable power capacity. During the 2023 financial year, which ended on 31 March 2023, producers used 35% renewable energy. ICRA said that they can expect to make costs savings of US$240m/yr from 2025 through the scale-up of renewables, including solar, wind and waste heat recovery. This would correspond to a 15 – 18% reduction of estimated energy costs for the 2025 financial year.

Over the same two-year period, ICRA forecast blended cements to rise to 81% of cement sales in the 2025 financial year, from 78% in the 2023 financial year.

Germany: Engineering company GEA has installed a carbon capture pilot plant at the Phoenix Zementwerke cement plant in Beckum, North Rhine-Westphalia. The supplier will now conduct testing over ‘several’ months, but said that it is confident that the cement plant is suitable for an installation to capture over 90% of its CO₂ emissions. GEA’s carbon capture systems run on energy from waste heat recovery, with minimal to zero extra electrical input.

Phoenix Zementwerke managing director Marcel Gustav Krogbeumker said “We consider carbon capture a very exciting technology. Thanks to GEA's decades of experience in emissions control, I am very positive that together we can develop and implement a solution."

France: Hoffmann Green Cement Technologies reported revenues of Euro1.68m during the first half of 2023, more than triple those recorded in the first half of 2022 (Euro544,000). The producer’s sales volumes of its clinkerless cement also more than tripled, to 7340t. It says it is on course to achieve its full-year 2023 target of 24,000t. The commissioning of its H2 plant in France raised the company’s installed production capacity by 250,000t.

Co-founders Julien Blanchard and David Hoffmann said "Thanks to the daily work of all our teams, we are accelerating the marketing of our innovative clinker-free cement in a construction market with demand for truly carbon-free solutions. Considering the seasonality of our sales, we intend to intensify the transformation of our order book into sales during the second half of 2023.”

Pakistan: The board of directors of Lucky Cement has approved US$37.1m-worth of investments in the construction of renewable energy infrastructure at the company’s Karachi and Pezu cement plants. The producer plans to build a 6.3MW solar power plant and a 28.8MW wind power plant at the Karachi plant in Sindh and a 2.5MW solar power plant at the Pezu plant in Khyber Pakhtunkhwa. Pakistan Company News has reported that the board also empowered Lucky Cement to evaluate its participation in the equity of its diversified industrial manufacturing subsidiary, Lucky Core Ventures.

US: Sublime Systems’ Sublime Cement reduced-CO₂ cement has received an ASTM C1157 designation. InterestingEngineering News has reported that this enables builders to use it in various projects in line with international building codes. Sublime Systems’ cement consists of lime and silica produced by electrolysis using non-carbonate calcium compounds.

CEO Leah Ellis said "Our aim is to make a profound and lasting impact on global CO₂ emissions. The ASTM C1157 designation is a validation of our efforts to integrate low-carbon innovation into quality construction materials."

Germany: IKN and KIMA Process Control are planning to work together on optimising energy recuperation and reducing the carbon footprint in clinker production by integrating machine learning software. The collaboration is intended to combine the expertise of KIMA Process in process automation and IKN as a process expert and equipment supplier for clinker production. The synergy should lead to more streamlined and efficient operations and highly reliable top-quality equipment.

In a statement the companies said, “We are excited about the potential of this collaboration to reshape the landscape of clinker production control and setting new benchmarks in the cement industry.”
