Finland: VTT Technical Research Centre subsidiary Carbonaide has concluded its seed funding round, having raised funds worth Euro1.8m. Lakan Betoni, which produces precast and ready-mix concrete, led the funding, along with utilities provider Vantaa Energy. Carbonaide will use the funds to build an industrial pilot plant for its carbon neutral precast concrete product at an existing precast concrete plant in Hollola. The plant will bind captured CO₂ in the product at atmospheric pressure. The process generates 50% lower CO₂ emissions than precast concrete production using ordinary Portland cement (OPC). Suitable raw materials include ground granulated blast furnace slag (GGBFS), green liquor dregs and bio-ash. In trial production, the use of GGBFS gave Carbonaide's concrete a negative carbon footprint of -60kg/m³.

Other sources of loans and in-kind contributions included Finnish state innovation fund Business Finland.

UK: The UK government has committed to investments worth Euro22.8bn in early deployments of carbon capture technology. It will announce a shortlist of new projects for deployment later in March 2022.

The government said "This unprecedented level of funding for the sector will unlock private investment and job creation across the UK, particularly on the east coast and in the North West of England and North Wales. It will also kick-start the delivery of subsequent phases of this new sustainable industry in the UK."

Ireland-based Ecocem responded to the budget with a call for funding for more short-term areas besides carbon capture. It said these will be essential in order for the UK cement and concrete industry to reach its 45% decarbonisation target by 2030. The slag-based cement products company called for funding for low-clinker technologies which have already been developed and can be rolled out at scale before 2030, until carbon capture becomes a 'scalable, viable option.'

India: Construction is underway on a section of National Highway 66 in Maharashtra which is being built of concrete made from ground granulated blast furnace slag (GGBFS) and slag cement. India Today News has reported that the Central Road Research Institute developed the technology, in partnership with the National Institute for Transforming India Aayog and the Council of Scientific and Industrial Research.

US: Research by the United States Geological Survey (USGS) estimates that local sales of iron and steel (ferrous) slags were 15Mt in 2022 with a value of around US$795m. This is a slight decrease from the 15.7Mt reported in 2021. 49% of the volume sold in 2022 was blast furnace slag and this accounted for the majority of the total value of the slag. Steel slag produced from basic oxygen and electric arc furnaces accounted for the remainder of sales. Around 2Mt of slag was imported for consumption.

The USGS said that slag was processed by 25 companies servicing active iron and steel facilities or reprocessing old slag piles at about 123 processing plants in 33 states, including facilities that import and grind unground slag to sell as ground granulated blast furnace slag (GGBFS). It added that domestic GGBFS remained in limited supply in 2022 because granulation cooling was available at only two active US-based blast furnaces and only one local plant produced pelletised slag in limited supply. It noted that granulated blast furnace slag was only ground domestically by cement companies.
