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.

UK: Breedon Group has acquired concrete block producer Broome Bros., construction firm Minster Surfacing and concrete block and aggregates producer Robinson Quarry Masters. Breedon Group said that the businesses will strengthen its presence around Doncaster in South Yorkshire, in Antrim, Northern Ireland, and 'from the Midlands to London.'

CEO Rob Wood said “Many of our transactions come to us through our local knowledge and personal engagement with the owners. As a result, our active mergers and acquisitions pipeline has continued to yield high quality, earnings-enhancing opportunities that will enable us to progress our sustainable growth strategy." He added "Each of these independent family-run businesses is aligned with our vertically-integrated operating model, providing further opportunity to pull through upstream building materials while extending our downstream footprint to deliver profitable growth.”

Business Live News has reported that the group has also completed its transition to the London Stock Exchange from the AIM exchange. Breedon Group said that this will enhance its corporate profile by helping to attract greater international investment.

Belgium: The EU Innovation Fund has awarded Euro4.5m to a consortium consisting of Lhoist, gas provider Fluxys Belgium, concrete products company Prefer and carbonation technology developer Orbix. The collaborators are working on a project called CO2ncrEAT. The project will carbonate steel sector by-products with captured CO₂ from Lhoist's Hermalle lime plant to produce alternative building materials. CO2ncrEAT will be the first project to employ Orbix's innovative technique for the purpose. Fluxys Belgium's pipeline technology will convey the Hermalle plant's emissions over a distance of 2km to a Prefer concrete blocks plant.

The consortium said that it will use 12,000t/yr of CO₂ to produce 100,000t/yr of reduced-CO₂ concrete blocks. The use of alternative raw materials in the blocks will further reduce their carbon footprint by 8000t/yr.

Lhoist Western Europe managing director Vincent Deleers said “The project fits perfectly with our willingness to actively develop CO₂ capture and sequestration technologies that are essential to the sustainability of our industry. We are delighted that our work on innovative solutions has been recognised by the European Innovation Fund and we look forward to working with our partners to bring CO2ncrEAT to the next level.”

Ecuador: Encapsulation in concrete served to destroy 110t of cocaine in Ecuador during the first nine months of 2022. The figure corresponds to 61% of cocaine seized by authorities during the period. Local press reported that the mixed slurry forms strong precast concrete elements, from which the cocaine is impossible to extract. Encapsulation accelerates destruction of the drug by a factor of 20 compared to incineration, with removal rates of up to 1500kg/hr.

Ecuadorian cocaine seizures at ports alone increased by 42% year-on-year throughout 2022, necessitating the operational improvements in disposal methods.

India: Siam Cement Big Bloc Construction Technologies has bought 60,000m³ of land at Ramosadi in Gujarat's Kheda District. The concrete producer informed the BSE Exchange that it plans to build an autoclaved aerated concrete (AAC) panel and block plant at the site.

India: CK Birla Group’s fibre cement roofing subsidiary HIL has agreed to acquire Fast Build Blocks for US$8.22m in a ‘slump sale.’ Fast Build Blocks produces autoclaved aerated concrete (AAC) blocks in Cuttack, Odisha. Press Trust of India News has reported that HIL is using the acquisition to establish a leadership position in the Eastern Indian market.

US: Prometheus Materials has successfully developed cement-free blocks from a material produced by biomineralising cyanobacteria. Dezeen News has reported that the American Society for Testing and Materials (ASTM) has approved the materials for construction applications.

Director Wil V Srubar III said "Coral reefs, shells and even the limestone we use to produce cement today show us that nature has already figured out how to bind minerals together in a strong, clever and efficient way. By working with nature to use existing microalgae to bind minerals and other materials together to create new types of sustainable biocomposite building materials, we can eliminate most, if not all, of the carbon emissions associated with traditional concrete-based building materials."

Indonesia: Indonesia Power says that it has processed coal fly ash and bottom ash from its Adipala power plant into building materials, including cement-free ready-mix concrete, concrete blocks, paving slabs and refractory casts. The energy company also supplies ash to mine reclamation and water neutralisation projects, according to LKBN Antara News. In total, it reused 135,000t of ash by-products in 2021. The company generates 85,000t/yr fly ash and bottom ash.

Sinar Tambang Arthaestari has previous targeted Indonesia Power’s ash products for use in its cement production.

UK: Cemex UK has launched ReadyBlock Zero, a zero carbon concrete block, on the UK market. The product joins the company’s Vertua reduced-CO₂ product range. Cemex UK achieved zero carbon production by means of offsetting. It said that ReadyBlock Zero will help builders to meet the UK’s government’s Future Homes Standard, which requires a 75 – 80% CO₂ emissions reduction in all newly built homes.

Cemex’s Europe regional urbanisation solutions director of asphalt, paving and building products Carl Platt said “We have developed the UK’s first carbon neutral concrete block to help housebuilders get ahead of the game when it comes to building low carbon homes that meet and exceed government guidelines and changes to building regulations. We want to make life easier for housebuilders to make simple sustainable choices that make large scale impacts on the often complex road to net zero. Concrete blocks are the most common structural component in the construction of UK homes, so by switching to zero carbon blocks, ReadyBlock Zero presents a huge opportunity for housebuilders to make significant carbon reductions.”

India: SCG International India has announced the launch of a joint venture with autoclaved aerated concrete block producer Bigbloc Construction. The joint venture will produce and sell lightweight concrete panels. It expects to commission a new 2.6Mm³/yr concrete panel plant in Gujarat in 2022. Bigbloc Construction holds the majority 52% stake in the venture.
