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.

Poland: Switzerland-based Holcim has acquired precast concrete producer HM Factory. HM Factory supplies precast concrete products manufactured in Poland to the Scandinavian export market. It employs 70 people across its operations.

Holcim’s Europe regional head Miljan Gutovic said “HM Factory is a perfect complement to our existing operations, offering multiple technological and raw material synergies. I look forward to welcoming the employees of HM Factory, whose expertise will be invaluable in accelerating green growth, especially in highly efficient modular construction.”

Bolivia: Construction of an upcoming 237,000m³/yr precast concrete plant in Uru Uru, Cercado Province, commenced on 13 December 2022. The plant will cost US$2.22m and have the capacity to produce 23,000 concrete paving blocks per day.

China: A team at Southeast University has developed an alternative concrete that contains 8% cement. It uses coral reef limestone fragments and biodebris with an upper particle size of 53mm as fine aggregate. The researchers concluded that the material proved suitable for use in precast concrete paving slab production.

Costa Rica: Holcim Costa Rica has acquired the heavy precast unit of Productos de Concreto for US$3.35m. The La Nación newspaper has reported that the company also increased its stake in prefabricated construction company Tecnología de Construcción to 100% from 49%. The latter deal's value was US$774,000.

Holcim Costa Rica's corporate affairs manager José Alfredo Alpízar Guzmán said that these latest acquisitions complement the producer's existing abilities to supply its customers.

India: Finland-based Betolar has launched its first concrete products manufactured using Geoprime on the Indian market. Geoprime is an additive designed for use in cement-free concrete production with ash and ground granulated blast furnace slag (GGBFS). The new concrete product range consists of precast blocks, paving slabs and tiles, and is currently on display at World of Concrete India in Mumbai, Maharashtra.

Betolar's India managing director Abhishek Bhattacharya said "We are happy to introduce our first products to our customers for the Indian markets. We have now moved from laboratory tests into the production phase, and can show concretely how well this solution works. It is great to hear the feedback from the concrete industry in the region to our sustainable solution. Decarbonisation of the concrete industry is a very current and important topic."

India: Three new Indian concrete companies have separately secured agreements for the use of Finland-based Betolar’s Geoprime alkali-activated slag and fly ash additive. Reuters News has reported that the companies are Balaiji Cement Products, Shiv Tiles and SNEH Precast. Engineering company Godrej & Boyce has also signed a letter of intent with the supplier for pilot production of concrete blocks, paving slabs and other elements.

Betolar expects producers to achieve global concrete production volumes of 250,000t/yr of concrete containing Geoprime by 2023.

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."

Italy: BHS-Sonthofen has acquired planetary concrete mixer producer Eurostar Concrete Technology. The Germany-based group says that Eurostar Concrete Technology’s planetary concrete mixers will diversify its own product portfolio, increasing its equipment and service flexibility.

Eurostar Concrete Technology’s mixers have batch capacities of up to 6000l. Their applications include precast concrete blocks and pipes production, as well as the production of special concrete for environmental purposes and use in the glass industry.

BHS-Sonthofen’s managing director Dennis Kemmann said “For plant manufacturers and sales partners, the expansion means an even more attractive product portfolio at a high technological level and with robust drive technology.”

Romania: Xella Romania has sold its Macon precast concrete operations to Romcim, a subsidiary of Ireland-based CRH. The operations being sold served the civil engineering and transport infrastructure end markets in Romania. The price of the divestment has not been disclosed.

Christophe Clemente, chief executive officer of Xella Group, said, "The sale of Macon's precast concrete division will sharpen Xella's profile in the autoclaved aerated concrete (AAC) and construction market and will allow us to focus our resources on the development of sustainable and efficient walling solutions for the building industry.”

Xella Romania acquired Macon Group in 2018. The addition added AAC as well as precast concrete, lime and terracotta operations. Parent company Germany-based Xella says that the acquisition made its subsidiary the largest AAC producer in Romania. The precast concrete business line is managed by Simbeton and operates two production facilities in Deva and Oradea.
