Ireland/France: Ecocem will showcase its Advanced Cement Technology (ACT) at the Buildings and Climate Global Forum in Paris on 7-8 March 2024. The French Government and United Nations Environment Programme (UNEP) will host the event, supported by the Global Alliance for Buildings and Construction (Global ABC). It aims to advance the climate outcomes of the United Nations Climate Change Conference (COP28) in 2023. Ecocem joins global policy-makers, industry stakeholders and international organisations as the event’s sole international cement technology company exhibitor.

Managing director Donal O'Riain said "The Buildings and Climate Global Forum is happening at a crucial moment for the planet. Urgent and deep decarbonisation of construction materials is essential to achieving the 2015 Paris Agreement targets.” He continued “Ecocem’s ACT low carbon technology can decarbonise the cement sector on a trajectory consistent with 1.5°C of global warming, the first major industry sector to achieve this feat. But we must now mobilise resolutely, rapidly and globally to deploy this technology. The first ambition should be a 50% reduction in CO₂ emissions from cement by 2030. Technology is no longer the barrier."

UAE: Emirates Steel Arkan has concluded a partnership for the deployment of Finland-based Magsort’s technology in steel slag processing at its Al Ain cement plant. ZAWYA News has reported that the partners expect the technology to help reduce the plant’s limestone and fuel consumption. This will reduce its CO₂ emissions by 15%.

Emirates Steel Arkan CEO Saeed Ghumran Al Remeithi said "Green solutions such as this will help decarbonise the sector's value chain."

US: The Department of Transportation has announced a US$5m initiative to investigate the use of steel slag in cement and concrete. This will take the form of a collaboration between the Department of Transportation and a selected US-based steel producer and university partner. The initiative seeks to reduce CO₂ emissions in the production of building materials. Prospective participants may view the grant opportunity here.

Transport secretary Pete Buttigieg said "We're proud to make this funding available to help develop the next generation of construction materials so that the future of our transport infrastructure is more resilient, more sustainable and made in America.”

Robert Hampshire, deputy assistant secretary for research and technology and chief science officer, said “This funding initiative will develop and advance innovative materials and technologies that support the nation’s goals to decarbonise the transportation sector by 2050, strengthen resilience of the nation’s transportation infrastructure, and address adverse environmental impacts created by the transportation system.”

Türkiye: Titan Cement International (TCI) has acquired concession rights to the Vezirhan pozzolana quarry in East Marmara. The quarry will help TCI to expand its low-carbon cement production capacity. By 2030, the company aims to reduce its CO₂ emissions by 35% from 1990 levels, and include 50% green products in its portfolio.

Titan Group Eastern Mediterranean regional director Christos Panagopoulos said “Access to Vezirhan quarry’s strong reserves potential and high-quality material will allow Titan to further broaden the portfolio of low-carbon cementitious products available to its customers. The quarry has access to a deep port and railway transport, facilitating both land and seaborne distribution across Titan's global locations.”

Group chief sustainability and innovation officer Leonidas Canellopoulos said “Being future-ready for a net zero world is more than just an ambition for Titan, and the acquisition of concession rights in Vezirhan is part of our solid roadmap that entails over 100 initiatives, covering the entire scope of our geographic operations and span of our value chain.”

Spain: Cementos Portland Valderrivas' Alcalá de Guadaíra plant has secured environmental clearance to use more alternative raw materials and alternative fuels (AF) in its cement production.

The company said "This achievement is a further boost to our sustainable work practices, respecting the environment and contributing to combatting climate change."

North America: A new coalition for the scaling and deployment of low-carbon building materials, the creation of new clean cement and concrete jobs and the promotion of environmental justice launched earlier in January 2024. Called the Decarbonized Cement and Concrete Alliance (DC2), it comprises alternative cement developers Biomason, Brimstone, Chement, Fortera and Terra CO₂, sequestration company Blue Planet Systems, circular concrete producer CarbonBuilt, biogenic limestone producer Minus Materials, hydrothermal processing technology developer Queens Carbon and electrified cement production technology developer Sublime Systems. DC2’s areas of engagement in policy will include tax credits, standards, ecolabeling and subsidisation, in line with the US Department of Energy’s Pathways to Commercial Liftoff: Low-Carbon Cement strategy.

CarbonBuilt’s government and community affairs manager Sal Brzozowski said “DC2’s platform of robust policy, standards and incentives to scale innovative solutions will not only accelerate deep decarbonisation, but also transform the concrete industry from one of the world’s largest CO₂ emitters to one of the world’s largest carbon sinks.”

Switzerland: Swiss cement shipments dropped by 10% year-on-year to 3.7Mt in 2023, from 4.1Mt in 2022. Shipments declined across all quarters, including by 10% quarter-on-quarter in the third quarter. Cement with a reduced clinker factor grew to account for 96% of shipments from 95%, and rail shipments rose to 38%. Ready-mixed concrete plants received 73% of shipments, and building sites 21%.

The Swiss cement association, Cemsuisse, said that it anticipates continued uncertainties and high import pressures in 2024.

Spain: Cementos La Cruz plans to build a new unit to produce reduced-CO₂ cement at its 1.5Mt/yr Abanilla grinding plant in Murcia. In a video posted on YouTube, the producer said that the new unit will produce cement using supplementary cementitious materials (SCMs) derived from industrial waste streams. Additionally, it will source 100% of its electricity consumption from biofuel-fired generators. Cementos La Cruz has secured Euro4.5m in European Union funding for the project.

General director Juan Luis Porrúa said that cement from the upcoming unit will have a specific carbon footprint below 200kg/t, and will eliminate over 400,000t of CO₂ emissions from Spanish construction in its first 10 years of operation.

Switzerland/UAE: The COP28 UAE Presidency named École Polytechnique Fédérale de Lausanne (EPFL) among its Energy Transition Changemakers in the Heavy Emitting Sectors category. EPFL won the prize for its LC3 limestone calcined clay cement, which replaces 50% of clinker content with calcined kaolinite clay and limestone. LC3 cement reduces CO₂ emissions by 40% compared to ordinary Portland cement (OPC), and is a readily available solution that can be scaled worldwide. EPFL noted the special importance of LC3 cement for CO₂ reduction efforts in developing countries, and sees it as having the potential to eliminate 500Mt/yr of global CO₂ emissions by 2030. In a post to LinkedIn, the LC3 Project said that nine plants around the world currently produce LC3 cement, with a further 20 planned before 2025.

India: Adani Group says that it will power 60% of its cement production using renewable energy by 2028. In a post on X, the group noted that its Adani Cement business uses fly ash or slag in cement production at 90% of its plants.
