India: Dalmia Bharat announced that its subsidiary, Dalmia Cement (Bharat), has entered into a share subscription and shareholders agreement to acquire a 26% stake in Truere Surya for US$5.3m. Truere Surya will establish a solar power project in Tamil Nadu, aligning with Dalmia Bharat’s goals to become carbon negative by 2040.

The solar project will have a capacity of 128MW. Completion of the transaction is anticipated within 4 - 6 months, pending customary conditions.

Japan: Taiheiyo Cement, ITOCHU, Nippon Steel, Mitsubishi Heavy Industries, INPEX, Taisei, and ITOCHU Oil Exploration have been chosen by the Japan Organisation for Metals and Energy Security (JOGMEC) to lead the engineering design work for key carbon capture and storage (CCS) initiatives. This selection marks a step towards Japan's ambitious goals to achieve carbon neutrality by 2050 and a 46% reduction in greenhouse gas emissions from financial year 2013 (FY13) levels by FY30.

The project encompasses front end engineering design (FEED) and appraisal drilling as critical next steps following a comprehensive feasibility study conducted in FY23. This prior study involved detailed assessments of CO₂ separation, capture, transportation and storage processes. The CCS initiative involves shipping CO₂ captured at Nippon Steel’s Kyushu Works in the Oita area and Daiichi Cement's Kawasaki plant, part of the Taiheiyo Cement Group, to designated storage sites.

Spain: Votorantim Cimentos will construct a solid recovered fuel (SRF) production plant at its subsidiary Cementos Cosmos’ plant in Oural, aiming to produce up to 0.15Mt/yr of alternative fuel, reports Digital Economia newspaper. The facility, spanning 5800m², will utilise non-recyclable industrial byproducts and various discarded materials from the local community such as plastic, paper and wood, to partially fuel the combustion in its cement kilns. The plant, currently in the public exhibition phase, will start production at 60% capacity, producing 85,000t/yr of alternative fuel. Plans include ramping up to full capacity to produce roughly 0.15Mt/yr. The new plant will create 15 jobs.

Votorantim Cimentos has not detailed the investment in the new facility, although the budget presented to the local council amounts to €12m.

Philippines: Republic Cement's resource recovery group, Ecoloop, has diverted 21.4 billion plastic sachets in 2023, equating to 110,000t of discarded materials utilised as alternative fuel in cement co-processing. This marks a 30% reduction in CO₂ emissions per ton of cement, according to The Philippine Star newspaper.

Ecoloop director Angela Edralin-Valencia said "This achievement represents a significant amount of materials diverted from landfills and bodies of water, such as oceans and urban waterways and further underscores Republic Cement’s commitment to environmental stewardship and circular economy principles."

Ireland: New regulations effective from 1 September 2024 require all state-funded building projects in Ireland - including roads, schools, and hospitals - to use low-carbon cement. The directive prohibits the use of CEM I cement, mandating a minimum of 30% replacement of clinker with low-carbon alternatives for public projects.

UK: A new study by the Mineral Products Association (MPA), supported by Innovate UK, has found that incorporating reclaimed clays and finely ground brick powder into cement production can reportedly lower the embodied CO₂ by up to 3%. The materials are used as calcined clay in the cement production process. The project aims to offer a viable alternative to fly ash and ground granulated blast-furnace slag, as resources diminish due to the steel industry's decarbonisation efforts.

MPA director Diana Casey said "Using discarded bricks and reclaimed clays will not only lower carbon and reduce the amount of materials sent to landfill but has the potential to create a whole new market if these clays become widely used in the construction industry, helping to retain economic value in the UK, secure jobs and attract investment."

UK: Material Evolution will launch the UK's ‘largest ultra-low carbon cement plant’ in Wrexham in October 2024, reports the Construction Enquirer. The new facility will produce 150,000t/yr of a cement that emits up to 85% less embodied CO₂ than Ordinary Portland Cement (OPC), according to the company. Material Evolution is the driving force behind the €9m Mevocrete project, funded by government-led Innovate UK, and utilises byproducts from the steel industry. Business co-founder Liz Gilligan said that Material Evolution aims to remove one gigatonne of carbon by 2040, while replacing OPC as the ‘go-to’ product for UK construction. The company plans to replicate and scale its production across the UK and Europe.

Chief science officer at Material Evolution and co-lead of the ‘Mevocrete’ project, David Hughes, said "Cement is a binder and what we’re looking at here is creating a net zero embodied carbon cement which is inherently more durable, which means our houses, infrastructure and transport highways would be transformed on mass industry scale, really tapping into a local and national picture of a net zero environment.”

New Zealand: Neocrete has entered a partnership with major cement manufacturers, including Cemex, Heidelberg Materials, CRH, Titan, Cementos Argos and Ultratech Cement to promote its new Activator product aimed at reducing the amount of cement required in concrete. The product uses volcanic ash or residual ash from industrial processes to cut the amount of cement required by 40% to 50%, according to the company. Neocrete aims to replace cement completely, resulting in carbon-free concrete, by 2027. The new product will be submitted for life cycle assessment once a new pilot plant in Mt Wellington is operational. The plant is valued at US$2m and will produce 0.12Mt/yr of cement, to meet 10% of New Zealand’s demand.

Co-founder Zarina Bazoeva said "We don't need to produce the whole volume of cement. We activate the concrete chemically with a small catalyst at 3kg compared to 100kg of cement. So, we can scale fast."

Switzerland: Holcim has entered a partnership with Kibag and Oxara for the production and distribution of Oxacrete Oulesse, a cement-free binder developed by Oxara. This new product reportedly aims to supply up to 10% of Switzerland's annual concrete market. Oxacrete Oulesse is made with materials from deconstruction, offering a low-carbon alternative to traditional cement.

Philippines: First Gen will supply electricity from geothermal sources to Holcim Philippines plants in Mindanao. Under the agreement, First Gen subsidiary Energy Development will provide 22% of the energy needs for Holcim's manufacturing facilities in Bunawan, Davao City, and Lugait, Misamis Oriental. This partnership is enabled by the Mindanao introduction of the retail competition and open access programme, allowing significant power consumers to select their electricity suppliers. Earlier in August 2024, Holcim announced an electricity supply agreement with Alsons Power to supply 80% of the energy needs for the two facilities.

First Gen president and chief operating officer Francis Giles Puno said "We are pleased to partner with Holcim Philippines to grow viably while decarbonising. It's not an easy journey to decarbonise and provide for a regenerative future. This requires collaboration not just through supplying power, but also through solutions that maximise and optimise electricity requirements and working to find a pathway towards net zero."
