US: Icon Build has nearly completed the construction of the upcoming Wolf Ranch new neighbourhood in Georgetown, Texas, using its 14m-wide 5t Vulcan 3D printer. Denmark-based architecture firm Bjarke Ingels Group designed the award-winning development, which will be entirely 3D printed using Icon Build’s high-printability Lavacrete concrete. CNN has reported that that the method of construction addresses on-going local labour and materials shortages.

Icon Build CEO Jason Ballard said "The US faces a shortfall of approximately 5m new homes, so there is a profound need to rapidly increase supply without compromising quality, beauty or sustainability, and that is exactly the strength of our technology.”

UAE: Saint-Gobain Weber has installed a new system at its Abu Dhabi mortars plant to recover dust from its crusher and re-inject it into the plant’s raw materials stream. This is part of a package of upgrades to lower the Abu Dhabi plant’s consumption of virgin materials, which also reduced its generation of waste by 4380t/yr between 2019 and 2023. The L’Usine Nouvelle newspaper has reported that other investments included the electrification of the plant’s forklift fleet.

Saint-Gobain reduced its Scope 1 and 2 CO₂ emissions by 14%, its non-recycled waste by 78% and its water footprint by 10% in the Middle East between 2017 and 2023.

Canada: Lafarge Canada has signed an agreement with power provider TransAlta to recover and process fly ash from the site of the latter's decommissioned Edmonton coal-fired power plant. The project will use Ash-TEK's Ponded Ash Beneficiation System (PABS) fly ash beneficiation technology. The processed ash will then be able to replace up to 25% of cement in low-CO₂ concrete production.

TransAlta previously secured with Lafarge Canada for the supply of renewable power to its Exshaw, Alberta, cement plant in February 2022.

Vietnam: Trung Hieu Development Corporation has secured a five-year contract to use Betolar’s alkali-activated slag and fly ash-based concrete additive Geoprime. Trung Hieu Development Corporation plans to source the materials for Geoprime from local industrial side streams. Dow Jones Institutional News has reported that the move will eliminate 80% of raw materials CO₂ emissions across its 120,000t/yr-worth precast concrete production capacity.

Betolar's Head of Asia Juha Pinomaa said "Vietnam is the world's third largest cement producer and fourth largest cement consumer, with 85Mt/yr. We estimate that the Vietnamese market represents significant commercial potential for us in the coming years due to the huge potential for cement replacement.” He concluded “We can promote the local circular economy and accelerate Vietnam's sustainable development efforts by directly offering cement-free alternatives. The Vietnamese steel and energy industry generates large amounts of steel slag and fly ash as side streams, which can be used for Geoprime-based concrete."

Mexico: The Mexican Ready-Mix Concrete Industry Association (AMIC) says that European natural gas shortages and disruptions to the supply of oil, chemicals and other goods as a result of the conflict in Ukraine may cause a rise in the cost of global cement production.

AMIC president Ana Laura Burciaga said "Having a conflict that delays the arrival of these products can make them more expensive because they would have to be obtained from more expensive sources due to shortages.” Burciaga continued "The area where the conflict is taking place was a major supplier of gas and we are concerned that this will have repercussions, especially in terms of a price increase when we have just suffered a very significant one of a magnitude we had not seen for many years."
