Mexico: Holcim Mexico has launched ISO14044-compliant full-lifecycle Environmental Product Declarations (EPDs) for its ready-mix concrete range. The company says that the EPDs will help designers and builders to inform their materials selection processes. The Redacción newspaper has reported that data from five cement plants contributed to the declarations.
Concrete and aggregates director Manuel Sirtori congratulated the team for "demonstrating leadership by promoting transparency and reducing emissions in the construction industry."
Power to Green Hydrogen consortium commissions green hydrogen plant at Cemex España’s Lloseta cement plant
15 March 2022Spain: A consortium consisting of Cemex España, energy suppliers Enagás and Redexis, renewable power and infrastructure company Acciona and 30 other partners has commissioned Europe’s first solar power-to-green hydrogen plant at the site of Cemex España’s Lloseta cement plant on Majorca. The EU contributed Euro10m to the approximately Euro50m project. Euro3.75 million came from the Balearic Islands Autonomous Community government and Euro2.5m from the Spanish Institute for Energy Diversification and Saving (IDAE) of the Ministry of the Ecological Transition. The project will generate 300t/yr of hydrogen, eradicating 20,700t/yr of CO2. The hydrogen will primarily fuel city buses in Palma, as well as air conditioning units in public and private buildings there.
China: Geely will include electric cement truck battery pack change facilities in its roll out of 5000 vehicle battery change stations across China. Carscoops News has reported that the stations will be able to remove vehicles’ 3.2t, 280kWh battery packs in five minutes and fully recharge them in an hour. Cement truck drivers will be able to access the service via a simple QR code scan.
Entsorga supplies solid recovered fuels storage, feeding and dosing systems to Indocement Tunggal Prakarsa
11 March 2022Indonesia: Entsorga has dispatched two Spider bridge cranes and two Pelican feeding and dosing systems for the construction of two new solid recovered fuel (SRF) storage, feeding and dosing systems at Indocement Tunggal Prakarsa’s 11.9Mt/yr Citeureup cement plant in Bogor Regency. The systems will have a total capacity of 50t/hr. An advanced supervision system will monitor and control their 24-hour operation. The Italy-based supplier says that both lines are highly automated and will reduce both CO2 emissions and fuel consumption.
CEO Francesco Galanzino “The systems will help the cement plant to maintain its 2030 sustainability commitments, in line with the policies of HeidelbergCement who is a real first mover in the path toward sustainability. Such project it is a very important step in a Country where environmental policies are in their early stage.”
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.
Cementir Holding launches Futurecem limestone calcined clay cement in the Benelux and France
04 March 2022Benelux/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.”
