UK: UK-based startup Cocoon has raised €4.9m in pre-seed funding to develop technology that repurposes byproducts from electrified steel furnaces into a ‘near-identical replacement’ for blast furnace slag, according to the company. The modular technology integrates into existing steel-making processes without disrupting operations or requiring high capital expenditure, reports UK Tech News. Cocoon targets a 50% replacement of cement in concrete, aiming to reduce emissions for producers. Initial tests are underway at a steel plant in northern England, followed by another in the US.

Cocoon CEO Eliot Brooks said "We’re turning a byproduct with little use into a valuable product that the market badly needs and can be easily integrated into existing supply chains. By repairing a broken link in the circular economy, Cocoon provides steel makers with a new revenue stream while meeting the low-carbon material needs of the concrete industry. For every 1t of Cocoon’s slag-based cementitious material used, 1t of CO₂ can be avoided."

Brooks hopes Cocoon's climate technology will be integrated into a pilot plant by late 2025.

South Korea: Ssangyong C&E has exported 30,000t of low-carbon limestone cement (Type IL) to the US, its first such shipment following three years of research and development, according to AJU News. The product reportedly has a reduced clinker content and maintains the same physical performance as general cement. The producer plans to export 200,000t to the US in 2024 and 600,000t in 2025.

A Ssangyong C&E official said "Currently, our country's national standards stipulate that mixed cement only uses slag, fly ash and pozzolan. In order to reduce carbon emissions in the future, conditions must be created where various types of eco-friendly cement, including limestone cement, can be used."

UK: Following a successful trial in mid 2024, Aggregate Industries will deploy the ‘first electric cement truck in the UK’, according to the company, with more to follow. The trucks will be based at the Cauldon cement plant, alongside the company’s existing fleet of 60 trucks. The vehicles are equipped with a 600kW motor to deliver both bulk and bagged cement. Aggregate Industries has partnered with Lomas Distribution, its contracted haulier for the UK domestic market.

Gareth Durnall, general manager at Lomas Distribution, said "We are excited to work together with Aggregate Industries in adopting sustainable practices."

Steve Curley, Aggregate Industries’ managing director of cement division, said "Introducing electric trucks in our operations marks a pivotal shift towards efficiency and sustainability and is all part of our ongoing effort to decarbonise the business and contribute to our own net zero Strategy."

UK: Aggregate Industries has appointed Tom Murphy as Carbon Capture Utilisation and Storage (CCUS) Project Manager at the Cauldon Cement Plant in Staffordshire. He will play a leading role in managing the introduction of a carbon capture unit at the site.

Murphy joins the subsidiary of Holcim from Tata Chemical Europe where he was the Plant Manager for a first-of-a-kind post combustion carbon capture plant. Prior to that, he worked as an Energy Chemical Engineer for Tata and as a Research Engineer for the Materials Processing Institute. He holds an undergraduate degree in chemical engineering from the University of Manchester.

The CCUS project at the Cauldon Cement Plant is part of the wider Peak Cluster partnership, which was formed by cement and lime producers around the Derbyshire Peak District region and aims to cut collective annual carbon emissions by 3Mt/yr by 2030. More than 0.6t/yr is targeted to be cut at Cauldon. The project is being led by Progressive Energy. It aims to capture and transport CO₂ emissions from Cauldon and other partner plants before sequestering them beneath the eastern Irish Sea in one of the storage options which the project has access to, including the Liverpool Bay CCS or the Morecambe Net Zero project.

China: China Energy Engineering (CEEC) has announced the completion of reliability testing for ‘CarbonBox’, Asia's ‘largest direct air capture device by capacity’, according to the company. Developed jointly by a CEEC subsidiary and Shanghai Jiao Tong University, CarbonBox can reportedly capture over 600t/yr of CO₂. This technology will help to contribute to the production of green methanol and aviation fuel. The device aims to reduce the traditionally high energy consumption and costs associated with direct air capture devices.

A recent report by the Administrative Centre for China’s Agenda 21 and two other institutes revealed that China is advancing in CCUS deployment, with nearly 100 planned and operational projects.

Germany: The University of Trier is transforming post-consumer materials into ‘ecological’ cement through a new research project that aims to find sustainable alternatives for the construction industry. The project involves using low-CO₂ industrial post-consumer materials as alternative cement binders, such as sludge from gravel and sand mining, as well as dust from quartzite extraction. The research will run for two years and is supported by the German Federal Environment Foundation.

Canada: Finland-based Wärtsilä will provide a hybrid-electric propulsion system for an 11,000t-capacity limestone carrier, commissioned by CSL Group with China-based CCCC Shanghai Equipment Engineering and Jingjiang Nanyang Shipbuilding. The order supports CSL Group’s decarbonisation strategy by optimising engine and battery load and reducing fuel consumption.

The vessel is scheduled for delivery to CSL Group in 2026 and will initially operate on a hybrid diesel and battery system, transitioning to full electric power by 2031 to reduce carbon emissions by 90%, according to CSL Group. Wärtsilä will supply the whole hybrid electric propulsion system, including generators, DC hub, energy management system, main propulsion e-motors, bow thruster e-motors and battery solution.

The director of Electrical & Power Systems at Wärtsilä Marine, Torsten Büssow, said "Wärtsilä is committed to making decarbonised shipping possible, so we are delighted to be supporting CSL with solutions that enhance the sustainability of their fleet. This is a short sea shipping vessel that will operate with a lot of manoeuvring and variable load profiles, and electrification and hybridisation systems are the most efficient for such vessels."

Australia: Calix has been awarded a US$10m grant from the Australian government’s Carbon Capture Technologies Program to build a commercial demonstration electric calciner for ‘near zero emissions’ lime and cement production. The grant covers up to 50% of the expenditure, contingent on meeting project milestones.

The project will utilise the Leilac technology to capture up to 20,000t/yr of CO₂ from the cement and lime manufacturing processes. The project will create two revenue streams via a ‘near zero emissions’ lime product, as well as up to 15,000t/yr of captured CO₂ being sold to the SM1 project for green methanol production.

In the second phase of the project, production will be expanded to include the processing of cement raw meal to a ‘near zero emissions’ clinker product, with captured CO₂ supplied for use.

Nigeria: Lafarge Africa has launched ECOPlanet Unicem, the country's first low-carbon multipurpose cement, from its Mfamosing plant in Cross River State. The new product is reportedly designed with over 30% reduction in CO₂ emissions. ECOPlanet will be available nationwide by the end of 2024.

Cameroon: Cimpor has inaugurated its new plant in Kribi, Cameroon. Following investments in Côte d'Ivoire, Cimpor embarked on this greenfield project in February 2020, integrating the ‘world's first’ operational flash calcined clay production line, launched on 29 October 2023.

Cimpor Cameroun now has an output of 1.2Mt/yr of cement and 0.4Mt/yr of calcined clay. Cimpor's calcined clay production technology - ‘deOHclay’ – reportedly saves up to 80% in CO₂ emissions, up to 35% in electricity consumption and up to 40% in thermal energy consumption per tonne. Compared to a plant with a similar capacity, this technology could reduce CO₂ emissions by around 0.2Mt/yr, according to the company. The new plant will reduce the country’s dependence on imports to meet local cement needs.
