China: Eaton and Langham hotels have collaborated with Green Island Cement to transform 8t of oyster shells into a sustainable cement alternative, sourcing 80% of the required limestone for cement.

Amie Lai Gor, general manager of sustainability at Great Eagle Holdings, parent company of the two hotels, said "We brought together like-minded partners to repurpose oyster shells as a sustainable raw material alternative for cement production. Our goal is to encourage more hotels and restaurants to participate, diverting more discarded oyster shells from landfills through upcycling.”

Raymond Cheung Wai-man, division manager at Green Island Cement, highlighted past challenges of separating the shells from impurities like mud and residual meat, which initially deterred the project.

Lai Gor added that future plans include working with local universities to assess the carbon reduction potential of substituting limestone with oyster shells in cement production. Despite the higher costs—tenfold compared to traditional limestone—Cheung believes that scaling up could significantly lower expenses.

Latvia/Lithuania: Capsol Technologies has won a contract to carry out two CapsolGo carbon capture demonstration campaigns at the Brocēni cement plant in Latvia and the Akmenės Cementas cement plant in Lithuania. Both plants are owned by Germany’s Schwenk Zement. Following a feasibility study earlier in 2024, the demonstrations will run from the fourth quarter of 2024 to the fourth quarter of 2025 and will showcase the CapsolEoP capture technology.

Philipp Staggat, chief product officer of Capsol Technologies, said "CapsolEoP offers lower energy consumption with higher CO₂ concentration than competitive technologies, and the capture cost for cement owners is reduced further as it doesn't require external steam supply. We are looking forward to demonstrating our technology on Schwenk's cement plants.”

CEO of Akmenės Cementas, Arturas Zaremba added "In collaboration with our clients and stakeholders, we are dedicated to addressing these challenges. The implementation of CapsolEoP technology at our Latvian and Lithuanian plants is a testament to our commitment, marking a significant stride towards the goal of capturing over 1.5Mt/yr of CO₂.”

Mexico: A second industrial byproducts processing line has been inaugurated at the Cemento Cruz Azul plant in Tepezalá, Aguascalientes. The new facility, which cost US$8.5m, will create 100 jobs and convert over 66,000t/yr of post-consumer materials into energy for the cement plant's processes.

Víctor Manuel Velázquez Rangel, president of the board of directors of Cooperativa Cruz Azul, said "This is the result of joint work, teamwork and a shared vision with the State Government, which has always been concerned about the carbon footprint, sustainability and the environment. With this project we leave testimony of our great commitment and demonstrate that innovation and technology can go hand in hand with the preservation of the environment."

Canada: Canada-based carbon capture, utilisation and storage (CCUS) company Carbon Upcycling has been admitted to the Portland Cement Association (PCA). This new membership aims to support industry efforts to achieve carbon neutrality. The US Department of Energy previously announced over US$1.2bn in funding for PCA member companies to launch decarbonisation projects under recent federal initiatives. Carbon Upcycling has been developing a commercial CCS system at CRH’s cement plant in Mississauga.

PCA president and CEO Mike Ireland said "We are thrilled to have Carbon Upcycling join us as a member of the PCA, given our shared commitment to sustainability. Their efforts are helping the cement industry increase circularity and advance the industry's commitment to achieving carbon neutrality."

CEO of Carbon Upcycling Apoorv Sinha said "The most effective and credible pathway to decarbonising the cement industry is through strategic partnerships and collaboration with long-time industry leaders in the infrastructure sector. Joining the PCA underscores our commitment to advance sustainable practices and substantially reduce carbon emissions. We look forward to forging a low-carbon, resilient future with our fellow members."

Austria: Alpacem will invest €50m to modernise its Wietersdorf plant, including a new cement grinding plant, reportedly capable of saving up to 21,000t/yr of CO₂ and reducing electricity consumption, according to the Kronen Zeitung. The plant is scheduled for completion and commissioning in 2027. In the future, a new cement silo plant will also be built in the Görtschitztal valley, directly connected to the railroad.

Florian Salzer, technical director at Alpacem Zement Austria said "With this new project, we are investing in a sustainable future and laying the foundations for energy-efficient and environmentally conscious cement grinding."

Managing director Lutz Weber added "Alpacem has a clear goal: CO₂-neutral production by 2035. To achieve this ambitious goal, we need a package of measures and a concrete path."

Philippines: Holcim Philippines will invest US$6.5m to upgrade its La Union plant and increase the use of alternative fuels and raw materials to 40%. The project will be implemented by Sinoma CBMIPH Construction and will be completed by late 2025, reports the Manila Bulletin.

Nicolas George, Holcim Philippines president and CEO, said the investment aims to reduce CO₂ emissions, promote recycling, support local waste management and provide income for northern Luzon farmers, who will supply biomass residues as alternative fuels.

General manager Zeng Youbing of Sinoma CBMIPH Construction said “This marks the third collaboration between Sinoma CBMIPH and Holcim Philippines since 2021. We are honoured to contribute to Holcim Philippines' decarbonisation and sustainability goals.”

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.

India: Thiruvananthapuram city Corporation has conducted a trial run of its refuse-derived fuel (RDF) plant at Sanmathi Park, Chala. The plant processes up to 1t/day of legacy waste, which is hard to segregate, to produce fuel for cement plants. The plant processes 40kg of materials per 15-minute cycle. Currently, non-recyclable materials are sent to Tamil Nadu cement plants. The government plans to establish at least one RDF plant per district as a permanent solution.

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."

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.
