Chile: Unacem has completed its acquisition of Spain-based Cementos La Unión’s Chilean cement business. The value of the asset, including assumed debts, was US$23m. The business consists of the 0.3t/yr San Antonio grinding plant and two ready-mix concrete plants with a total capacity of 336,000m² /yr.

Germany: Scientists at the University of Kassel in Hessen have launched a study into the use of ash from waste incinerators in precast concrete production. The Hessische Allgemeine newspaper has reported that a waste-to-energy plant in Kassel will provide the ash for concrete production in partnership with local companies Kimm Baustoffe and Gebäudeke Baustoff-Recycling. The study aims to produce pre-cast concrete elements containing at least 30% ash, beginning with paving slabs and noise barriers.

Project leader David Laner said that ash has the potential to help lower concrete’s carbon footprint. He said “So far, it has been put to lesser-value uses; we make a product out of it - upcycling instead of downcycling.”

Canada: Habitats for Humanity has again partnered with Lafarge Canada for its annual affordable housing fundraiser in Kingston, Ontario. This year, the partners will attempt to raise US$21,700 over 27 days to support the construction of sustainable housing in Eastern Canada. Lafarge Canada has pledged 80m3 of its ECOPact reduced-CO₂ concrete to the project.

Eastern Canada regional head of environment and sustainability Rob Cumming said "Our sustainability goals overlap safe housing with reduced climate impact.” He added "We are excited about this first milestone and are looking forward to the future supply of our ECOPlanet solutions.”

Azerbaijan: Cement companies increased the total volume of cement produced in the first eight months of 2021 by 1.5% year-on-year to 2.2Mt from 2.17Mt in the corresponding period of 2020. Meanwhile, ready-mix concrete production increased sharply, by 39% to 1.7Mt from 1.3Mt.

On-going large-scale state construction projects the new territories East of Zangazur and Karabakh are anticipated to increase full-year cement production in 2021 and into subsequent years.
