France: Ireland-based Ecocem has entered into a new agreement with Saint-Gobain's France-based concrete subsidiary POINT.P. Under the agreement, Ecocem will supply its ACT alternative cement for use in POINT.P's precast and ready-mix concrete production. Ecocem said that the partnership is an opportunity for it to develop and market new low-carbon binders.

Ecocem executive director Olivier Guise said "This partnership with POINT.P is a natural extension of the alliance announced with the Saint-Gobain Group in October 2022. The shared objective is to accelerate the widespread deployment of low-carbon cements in France, both in the ready-mix concrete and precast concrete markets. By paving the way for the replacement of current traditional cements with ACT technology, our partner POINT.P has a real opportunity to meet its ambitious carbon reduction targets by 2030. We are firmly committed to this partnership and to working with a partner who shares our ambitions for rapid decarbonisation of the construction industry."

Ecocem is 25% owned by France-based Saint-Gobain.

Denmark: Finland-based Betolar has supplied its Geoprime additive for its maiden construction project in Denmark. Its customer IBF used the additive to produce low-cement paving stones for a 1.5 hectare expansion to the lorry park at the Port of Aalborg. The stones consisted of an 84mm-thick cement-free base made of Geoprime material, with a 6mm-thick cement-based concrete top. The supplier said that the use of Geoprime reduced the project's cement consumption by 90%. This more than halved the carbon footprint of the work.

Betolar's chief commercial officer Ville Voipio said "This shows that the circular economy solution we have developed, which utilises industrial side streams, also works in large construction projects. We have been doing development work with IBF for a long time. Now there is a product on the Danish market that radically cuts emissions compared to traditional products."

Denmark is committed to eliminating 70% of its annual CO₂ emissions between 2020 and 2030.

Japan: A team at the University of Tokyo has developed cement-free alternative concrete from ultra-fine sand and fly ash. NHK has reported that the process uses recyclable alcohols and has lower CO₂ emissions compared to concrete production using ordinary Portland cement. Research with industrial partners into possible construction sector applications is underway. Partnerships with Japanese ready-mixed concrete producers are reportedly also under discussion.

Egypt: France-based Saint-Gobain has obtained outright ownership of mortars producer United Paints and Chemicals (Drymix). Saint-Gobain paid US$25m for the acquisition, according to Business News Africa. Drymix operates the 240,000t/yr ‘6th of October City’ mortar plant in Giza Governorate.

Saint-Gobain operates two other building materials plants in Egypt, in Alexandria and Monufia Governorates.

France: Lafarge France is participating in a 76-unit housing development project called Recygénie, at Gennevilliers in Hauts-de-Seine. Lafarge France will supply the project with 100% recycled concrete for use in facades, interior walls and roof slabs. It produced 2000t of 100% recycled 'clinker' at its Altkirch cement plant in Haut-Rhin during a suspension of ordinary clinker production in 2022. It has produced 1600m³ of recycled concrete to date. The concrete won the New Materials Prize at L'Usine Nouvelle's Sustainable Industry Awards 2023.

The Recygénie housing project is due for delivery in late 2024.
