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: The Portland Cement Association (PCA) has told the Department of Energy’s Advanced Manufacturing Office (AMO) that federal policy and support is vital to accelerate the deployment of technologies that can decarbonise the local industrial sector. In its comments to the office, the PCA said that it shares the Biden-Harris Administration’s goal of carbon neutrality by 2050 through its own Roadmap to Carbon Neutrality, which lays out a pathway to achieve this across the cement-concrete-construction value chain by 2050. However, it warned that without strong federal support the AMO’s timeline to reach carbon neutrality across industry was unrealistic due to the “significant technical, legal and economic challenges regarding technologies like carbon capture utilisation and storage (CCUS), and others including hydrogen fuel and kiln electrification.”

“Federal policy must accelerate the significant technology, funding, and market innovation needed for rapid decarbonisation while preserving economic growth and international competitiveness,” said Sean O’Neill, senior vice president of government affairs at the PCA. “The adoption of CCUS is key to achieving deep decarbonisation in the cement industry.”

The PCA added that with the right federal and state policies, CCUS could become scalable within 10 years but infrastructure, policy, permitting and funding challenges remain. It suggested that tax incentive reforms and the use of Department of Energy loan programmes could accelerate early investment and adoption of CCUS.

The use of hydrogen fuels and kiln electrification was mentioned but these technologies are seen as being at least 15 – 20 years away. The association said that hydrogen remained very expensive and there was little current infrastructure for the transport and storage of hydrogen. More research and development is required to start evaluating the efficacy of kiln electrification.

Nigeria: Lafarge Africa, Holcim’s subsidiary in Nigeria and South Africa, says that it acheived record full-year results in 2021. Its net sales were US$705m, up by 27% year-on-year from US$554m in 2020. Meanwhile, its recurring earnings before interest, taxation, depreciation and amortisation (EBIT) rose by 43% to US$157m from US$110m.

CEO Khaled El Dokani said "Our 2021 performance showed significant improvement.” He added “We are equally pleased with the progress we are making on sustainability. Our use of affordable clean energy and agro-ecology footprint are in accordance with our net zero pledge journey."

In 2022, the company forecast ‘good demand momentum’ as it continues to maximise volume opportunities across its markets, while actively managing costs. During the year, it also plans to consolidate its sustainability efforts.

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.”

US: Cemex USA has begun selling Portland limestone cement produced at its Brooksville, Florida, and Demopolis, Alabama, plants across the Southeastern US. The producer says that the cement retains the durability of ordinary Portland cement or is more durable while reducing CO₂ emissions by 10%. Cemex USA aims to increase its PLC production at the plants, and possibly to begin producing it at other US cement plants, in early 2022.

President Jaime Muguiro said "At Cemex, we acknowledge that climate action is one of the most important issues facing our world, and we are committed to being part of the solution. Our company has ambitious emission-reduction targets, and by offering lower carbon products that deliver brilliant performance like PLC, we can continue to work toward those goals while encouraging customers to join us in the journey."

Indonesia: Indonesia Power says that it has processed coal fly ash and bottom ash from its Adipala power plant into building materials, including cement-free ready-mix concrete, concrete blocks, paving slabs and refractory casts. The energy company also supplies ash to mine reclamation and water neutralisation projects, according to LKBN Antara News. In total, it reused 135,000t of ash by-products in 2021. The company generates 85,000t/yr fly ash and bottom ash.

Sinar Tambang Arthaestari has previous targeted Indonesia Power’s ash products for use in its cement production.
