US: Charah Solutions has signed a contract with Associated Electric Cooperative (AECI) to receive bottom ash, fly ash and boiler slag from its Thomas Hill Energy Center coal-fired power plant in Missouri until 2026. Charah Solutions will recycle the by-products to produce supplementary cementitious products and redistribute these through its MultiSource materials network. The network consists of 40 locations across the US.

President and CEO Scott Sewell said "We are delighted to partner with AECI to manage their ash marketing needs at Thomas Hill while supplying our concrete producers with the high-quality material they need."

Spain/Norway: A team from Cartagen Polytechnic and Ostfold University College has demonstrated that Cementos La Cruz could reduce the cost of its concrete production by Euro1.45/m3, or Euro29,000/month by curing concrete with captured CO₂. EuropaPress has reported that the use of CO₂ would reduce the amount of cement required by 7 – 8%. This in turn would remove an estimated 4.6% of CO₂ from the concrete’s production.

Australia: A paper published in the journal Resources, Conservation and Recycling has reported that concrete made with treated slag is 8% stronger than standard slag concrete and 17% stronger than concrete made with conventional aggregates. A Royal Melbourne Institute of Technology (RMIT) team produced treated slag concrete using slag that had absorbed phosphate, magnesium, iron, calcium, silica and aluminium during use in wastewater treatment. Researcher Biplob Pramanik said, “The things that we want to remove from water are actually beneficial to concrete.” Pramanik said that the findings have promising implications for the water and concrete sectors within the circular economy.
