Nigeria: BUA Cement plans to use loans worth US$500m towards the construction of two new 3Mt/yr cement plants in Sokoto State. When operational, the new plants will increase the producer's installed capacity by 55% to 17Mt/yr. Local press has reported that BUA Cement plans to run both cement plants using solar power, and to produce cement using alternative fuel (AF). Additionally, the producer will use a portion of the funding to replace part of its diesel-fuelled cement truck fleet with new natural gas-fuelled models.

Of a total US$500m in financing secured by BUA Cement on 5 June 2023, the International Finance Corporation (IFC) lent US$161m (32%) and African Development Bank, Africa Finance Corporation and the German Investment Corporation jointly lent US$245m (49%), with the remainder advanced by institutional investors.

India: JSW Cement has signed a US$50m sustainability-linked loan agreement with BNP Paribas Singapore. The Hindu BusinessLine newspaper has reported that the producer plans to use the funds for capital expenditure projects aimed to more than double its production capacity to 50Mt/yr from 17Mt/yr. Current plans include US$388m in investments in the construction of a 2.5Mt/yr integrated cement plant in Madhya Pradesh and a 2.5Mt/yr grinding plant in Uttar Pradesh.

The latest loan from BNP Paribas is the second of its kind taken by the group, following a US$48.5m sustainability-linked loan from Japan-based MUFG Bank in October 2022.

Sweden: Nordkalk has produced lime at its Koping lime plant using 30% biofuel as alternative fuel (AF). The producer now aims to increase the substitution rate to 50%. Nordkalk subsidiary Kalkproduktion Storugns recently began trialling 100% liquid biofuel substitution in continuous operations at its Larbro lime plant. ENP Newswire has reported that both projects are part of a CO₂ emissions reduction initiative in partnership with the Swedish Energy Agency and Umea University.

Denmark: Aalborg Portland and US-based Fidelis New Energy have signed a letter of intent to collaborate on the onshore storage of captured CO₂ from the cement producer's Aalborg cement plant in North Jutland. The partners will convey captured CO₂ from the plant to Fidelis New Energy's upcoming Norne Carbon Storage Hub at East Port of Aalborg via a pipeline. The pipeline is scheduled for commissioning ahead of the launch of the Aalborg cement plant's upcoming carbon capture system in 2030. The system will capture 400,000t/yr of CO₂ from the plant's flue gases.

Fidelis New Energy's Norne Carbon Storage Hub is due to commence operations in 2026. It will have a handling capacity of 4Mt/yr of CO₂, with the possibility of subsequently expanding to 8Mt/yr.

Philippines: Holcim Philippines introduced Holcim Optima, a blended Portland limestone cement (PLC), on the Philippine market on 8 June 2023. The Business Mirror newspaper has reported that Holcim Optima cement offers 10% reduced CO₂ emissions compared to ordinary Portland cement (OPC).

President and CEO Horia Adrian said that Holcim Optima cement 'delivers the same strength, workability and durability as OPC and remains compatible with other cement additives such as slag and fly ash. The new product is best used in large building projects and available in bulk.' Adrian added "It is a timely product for the Philippines, as infrastructure building accelerates and green demand grows."

Egypt: Heidelberg Materials subsidiary Suez Cement has invested US$16m in upgrading its operations towards increased alternative fuel (AF) use since 2010. The producer uses AF in the burners and kilns of all three of its cement plants, at Helwan, Kattameya and Suez. Meanwhile, Suez Cement has invested US$60m in dust control measures over the same period. Other on-going investments include US$25m in the construction of a waste heat recovery (WHR) plant at the Helwan cement plant. The company is committed to reaching a 24% reduction in its CO₂ emissions between 2019 and 2030.

Technical director Omar Khorshid said “We are committed to pursue initiatives to broaden our range of innovative and eco-friendly building solutions, advance operational efficiency through digitalisation and strengthen customer engagement for better business results and more positive impact."

Taiwan: Taiwan Cement Corporation aims to diversify its business away from cement by increasing its sales from energy storage and vehicle charging. It aims to derive over 50% of its revenues from other activities besides cement by 2025. The Taipei Times newspaper has reported that the producer will continue to produce 80Mt/yr of cement. The company said that the reason behind its planned diversification is its responsibility to help reduce global net CO₂ emissions.

Chair Nelson Chang said “Carbon reductions must be fast and efficient, and the use of solar and other green energy resources in producing cement is not enough to offset carbon emissions. That means Taiwan Cement has to press ahead and develop carbon capture techniques that would help mitigate the negative impact of cement production on the environment.”

UK: SigmaRoc subsidiary CCP has launched Greenbloc Standard, Ultra and Premium. The new designations correspond to 50%, 80% and 100% cement substitution. Professional Builder News has reported that Using Greenbloc Standard reduces structures’ CO₂ emissions by 77% compared with structures built with conventional ordinary Portland cement (OPC)-based blocks. For an average semi-detached house, this is equivalent to 2.7t of CO₂.

CCP general manager Phil Rotheram said “The expansion of our Greenbloc range continues our commitment to sustainable alternatives to our product offering as we fully commit to the challenges of removing embodied carbon from the built environment.”

Greenbloc Ultra featured in a gold medal-winning garden at the RHS Chelsea Flower Show 2023 in May 2023.

Canada: The district council of Capital Regional District (CRD) says that it expects to resume sending biosolids to Lafarge Canada's Richmond cement plant in early June 2023. This follows a reported reduction in production at the unit in 2023 and 2022, according to the Times Colonist newspaper. The 1.1Mt/yr cement plant previously used biosolids supplied by the CRD as an alternative fuel in its cement production. However, during the current hiatus the biosolids have been sent to landfill instead.

The Richmond cement plant is the site of the CO₂MENT carbon capture and utilisation project. The project proceeded to its third phase, which consists of a capture capacity expansion and the installation of a liquefaction plant, in May 2023.

UK: CRH subsidiary Tarmac has pledged its support to the Route to Net Zero initiative to decarbonise the UK's logistics sector. Under the initiative, companies involved in transportation will implement changes aimed at achieving net zero CO₂ emissions by 2050. Tarmac already transports 9Mt/yr of materials around the UK by rail.

Tarmac's logistics director Graham Waters said “Signing up to Logistics UK’s Route to Net Zero pledge marks a further step for our business, underscoring our commitment to eliminating carbon emissions from our extensive UK-wide logistics networks and accelerating this process through collaboration with our haulier partners and the wider industry."
