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.”

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.

US: Lafarge North America has reported that its Paulding, Ohio, plant achieved 99% alternative fuel (AF) substitution in its cement production, up from 95% in past years. The operator said that the fuel change saved 205,000t of CO₂ emissions in 2021.
