Saudi Arabia: Al Kifah Ready-Mix & Blocks (KRB) has announced the upcoming launch of its ConGreen reduced-CO₂ concrete products range at the Big 5 Saudi construction summit on 28 – 31 March 2022. ConGreen concretes replace clinker with lower-carbon materials such as pozzolan and use Canada-based Carbon Cure Technologies’ embedded recycled CO₂ technology to reduce its carbon footprint by up to 30% compared to conventional ordinary Portland cement (OPC) concretes. In addition to this, KRB says that ConGreen concretes also provide improved workability and pumpability properties, as well as being highly durable, with high passing and finishability. They have very low rapid chloride permeability (RCP), water absorption and water permeability properties and low heat of hydration.

General Manager Nigel Harries said “We are committed to driving energy efficiency and addressing the global emission challenges. We aim to help build a better community and environment-friendly facilities by producing high-quality concrete, such as ConGreen, that has a reduced environmental impact and is characterised by its high performance, durability and sustainability, with a low carbon footprint as compared with standard concrete.”

Spain: HeidelbergCement is starting the Neuclicem carbon capture use and storage (CCUS) project at its integrated Arrigorriaga plant near Bilbao. Local electricity company Volbas and the Tecnalia Research & Innovation centre are participating in the initiative. The project intends to look at a process based on the mineralisation of alkaline waste, such as residual construction waste or steel slag, by accelerated carbonation using CO₂ from the flue gas at the plant. The resulting materials will then be used as additives in cement production or to reduce the use of clinker. The scheme will study its viability of the process on an industrial scale.

The Neuclicem project has an estimated duration of 14 months. Its results are intended to prepare the way for scaling up to a subsequent industrial prototype. The project is partially financed by Ihobe, an environmental management division of the regional Basque government.

Germany: Rohrdorfer and Austria-based Andritz Group are in the process of installing a 2t/day CO₂ separation plant on the roof of the former’s Rohrdorf cement plant in Bavaria. The pilot plant will capture CO₂ from the plant’s emissions for use by the regional chemicals industry. The Ingenieur newspaper has reported that it will cost Euro3m and is scheduled for commissioning before June 2022. It is the first installation of its kind at a German cement plant.

Rohrdorfer’s plant and process engineering manager Helmut Leibinger said “We must begin to see CO₂ as a product of value rather than a problem. With CO₂ as a carbon source, Germany can protect the climate and at the same time become less dependent on oil and natural gas. In addition, value creation and jobs will remain in the country.”

New Zealand: Golden Bay Cement has obtained two hydrogen-fuelled cement trucks produced by Hyzon. TR Group leased the vehicles to the cement company.

Golden Bay Cement said “These two zero emission green trucks signal the future, and are just another step we take to a smaller carbon footprint across our business.”

Switzerland: Vigier Ciment is operating a self-charging electric dump truck at its limestone and marl quarry in Biel. The 45t truck’s regenerative braking system recharges its 600kwh lithium battery on the downhill trip from the quarry to the primary crusher. Its 65t capacity more than doubles its weight when laden, easily enabling it to recover charge for the return trip. Each trip generates an estimated 10kwh of surplus energy. In ordinary use, this would equate to 77Mwh/yr. It saves 50,000 – 100,000l/yr of diesel and eliminates an estimated 196t/yr of CO₂. Green Car Reports has reported that Kuhn Schweiz built the dump truck, based on Japan-based Komatsu’s HB model truck. It is the world’s largest electric vehicle.

Benelux/France: Cementir Holding has introduced its Futurecem limestone calcined clay cement into the Benelux and French cement markets. Futurecem cement applies Cementir Holding’s patented processes to substitute over 35% of clinker in cement with limestone and calcined clay, preserving the cement’s strength and quality while reducing its carbon footprint by 30% compared to ordinary Portland cement (OPC).

Cementir Holding previously rolled out Futurecem cement in Denmark in 2021. In 2022, it plans to launch InBind high performance concrete (HPC) and ReCover ultra-high performance concrete (UHPC) to expand its range of HPC and UHPCs using Futurecem technology.

Eddy Fostier, managing director of Cementir Holding’s Belgian subsidiary CCB, said “Thanks to the joint efforts of the group and CCB teams, Futurecem technology is the main pillar for CCB’s low carbon transition within the Group roadmap. This product technology is matching customer needs, highlighted through a specific survey carried out across the most relevant market areas and applications.” Fostier concluded “I’m fully convinced that Futurecem will play a relevant role in the decarbonisation of the construction industry, where cement and concrete are essential building materials both in the present and in the future.”

US: Titan America’s Essex cement distribution facility at the Port of Newark, New Jersey, has made its first dispatches of Type IL Portland limestone cement (PLC) to New Jersey and the New York Metropolitan Area. The producer said that the Essex terminal is due to complete its transition to 100% reduced-CO₂ cement dispatches in 2022. Titan America says that it is the leading supplier of Type IL PLC on the US domestic market.

Sales Manager Joe Tedesco said “We see an increase in demand as infrastructure money is budgeted by transportation agencies requiring construction with the use of lower-carbon cement.”

US: Denmark-based life sciences investment company Novo Holdings says that it has invested US$65m in bio-based clinker-free cement producer Biomason. Biomason uses microorganisms to grow its Biocement cement, without heating or CO₂ emissions. The producer is in its Series C round of financing. Novo Holdings previously invested in its Series B financing round.

Japan: Mitsubishi Heavy Industries Engineering has won the Ministry of Economy, Trade and Industry’s highest prize for contributions to industrial decarbonisation, the Minister’s Award, for its development and commercialisation of its CO₂ capture system. The system is based on KS-21 solvent technology, developed in partnership with Kansai Electric Power, and the company’s Advanced KM CDR Process capture model. Mitsubishi Heavy Industries Engineering has successfully supported cement industry customers in implementing the system.

Belgium: Cemex has joined the Cambridge Institute for Sustainability Leadership (CISL)’s Corporate Leaders Group Europe in order to lead the corporate transition to a climate neutral economy. The company joins a cross-sectoral body of members from across the EU.

Cemex’s Europe, Middle East and Africa regional president Sergio Menendez said “With its Future in Action programme, Cemex is committed to leading on the road to carbon neutrality. We are proud to join forces with the CISL’s Corporate Leaders Group Europe and other global companies to accelerate the decarbonisation of the built environment. We look forward to working together with the Corporate Leaders Group Europe to help us all achieve our shared climate action goals in Europe.”
