CarbonBuilt’s reduced-CO2 concrete block technology win three Fast Company Innovation by Design prizes

24 August 2023

US: Carbon Built’s proprietary technology for the production of reduced-CO2 concrete blocks won awards across three categories at the Fast Company Innovation by Design Awards 2023. The product won the Circular Design, Materials and Sustainability prizes. Carbon Built’s technology enables existing concrete block plants to use common alternative raw materials to produce blocks with 70 – 100% lower CO2 emissions than ordinary Portland cement-based blocks.

Block-Lite to retrofit CO2-curing system at Flagstaff concrete block plant

21 August 2023

US: Block-Lite plans to install a system to cure concrete blocks using direct air capture (DAC)-sourced CO2 at its Flagstaff, Arizona, concrete block plant. The upgrade will implement CarbonBuilt’s low-CO2 concrete production technology and AirCapture’s modular DAC technology, across five or six capture units. Direct air capture will thus remove 500 – 600t/yr of CO2 from the atmosphere, while process changes will reduce CO2 emissions from the Flagstaff plant by over 2000t/yr. The project has attracted fundraising from the 4 Corners Carbon Coalition (4CCC), with a goal of US$50,000. The Arizon Daily Sun newspaper has reported that Block-Lite plans to supply its first shipment of low-CO2 blocks to a 50-home development by Habitat for Humanity in Flagstaff.

Betolar and Consolis Parma to develop reduced-CO2 hollow concrete slabs

27 June 2023

Finland: Betolar has signed a cooperation agreement with concrete producer Consolis Parma to develop reduced-CO2 hollow concrete slabs. The development process will implement Betolar's Geoprime binder into Consolis Parma's concrete production. Consolis Parma is committed to halving its CO2 emissions between 2021 and 2035.

Consolis Parma's Technology Director Juha Rämö said “The use of alternative new binder combinations and additives that ensure the efficiency of the manufacturing process are key factors in achieving our climate goals. We are actively seeking new channels to address these challenges. The cooperation with Betolar is an important new partnership for us."

CCP expands Greenbloc reduced-cement concrete block range

02 June 2023

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.

Breedon Group completes three acquisitions and lists on the London Stock Exchange

19 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.

SRM Institute of Science and Technology patents paving block containing waste printed circuit board

02 February 2023

India: A team at SRM Institute of Science and Technology has patented a new concrete paving block produced using fibres from waste printed circuit board (WPCB). The refuse-derived material will replace some sand and clay in the concrete mix. SRM Institute of Science and Technology said that India generates 2Mt/yr of electronic waste (e-waste), and additionally imports this type of waste from other countries. Besides being non-biodegradable, WPCB is contaminated with colouring chemicals.

The developers said "The steadily rising volume of electronic waste poses a serious hazard to human health and the environment."

Prefer and others secure Euro4.5m in EU funding for development of carbon negative concrete blocks

19 January 2023

Belgium: The EU Innovation Fund has awarded Euro4.5m to a consortium consisting of Prefer, gas provider Fluxys Belgium, lime producer Lhoist 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.

Prefer managing director Raphaël Grimont said “As market leader, we must ensure the sustainability of our business by offering innovative and eco-friendly products to our customers. With the CO2ncrEAT project, our building materials will be produced through a sustainable and efficient process and based on local, circular raw materials. The Prefer masonry block of tomorrow will retain all the advantages of the traditional block, with the difference that it will benefit from a negative carbon footprint. We are proud to develop this exceptional project together with key industrial partners, while benefitting from the trust of the European, Belgian and Walloon authorities.”
