US: Holcim has commissioned 10 Hyliion Hypertruck ERX electric trucks in its Oklahoma and Texas cement and concrete operations. The cement producer says that the trucks reduce CO₂ emissions by 89% when using renewable natural gas compared to conventional diesel vehicles.

Holcim US aggregates and construction materials CEO Jay Moreau said “This agreement with Hyliion underscores the direction Holcim is taking around the globe to reach our sustainability and environmental goals. By integrating sustainable technologies like electric vehicles into our operations, such as those of Hyliion, we are able to build on our promise of making greener cities, reducing emissions and driving the circular economy.”

Germany: The Ministry for Economy and Climate Protection has presented HeidelbergCement with its German Climate and Environment Innovation Prize (IKU) for its ReConcrete-360° concrete recycling process. The process retrieves hardened cement paste from waste demolition concrete for use in place of limestone in clinker and cement production. The recycled material can also bind CO₂ to act as a carbon sink.

Global research and development Wolfgang Dienemann said “With ReConcrete-360°, we have succeeded in developing a limestone substitute from demolished concrete that also allows us to use the carbon-containing exhaust gases from cement production. A small revolution with a big impact: In Germany alone, the CO₂ savings potential of this process is 10Mt/yr. The IKU award underlines that we can be proud of our pioneering innovation.”

Italy: Buzzi Unicem’s net sales grew by 17.2% year-on-year to Euro800m in the first quarter of 2022 from Euro682m in the same period in 2021. Its cement and ready-mixed concrete sales volumes rose by 2.9% to 6.36Mt and 6% to 2.69Mm³ respectively. The group reported growing sales volumes in Central Europe, Poland, the Czech Republic and the US but it noted a slowdown in Italy. Sales volumes were also disrupted in Ukraine and Russia due to the ongoing war between the countries. The group added that its prices were ‘markedly’ up in all markets where it operates to offset rising prices of raw materials and energy.

The company said that in Ukraine it was forced to suspend nearly all of the production and commercial activities at both of its plants when Russia invaded the country. In Russia it said that retaliatory economic sanctions led by the US and European Union had led to a “significant revision of the country's growth prospects.” Local sales volumes significantly slowed down in March 2022 after hostilities started but local operations still managed to report some growth in sales even in spite negative currency exchange effects. Buzzi Unicem said that, “Due to the sanctions imposed on Russia by the European institutions, we decided to immediately withdraw from any operational involvement in the activities carried out by the subsidiary OOO SLK Cement in Russia. Consequently, further strategic initiatives in the country will be suspended.”

Denmark: GE Renewable Energy has invested in a minority stake in COBOD International. The companies said that the investment will build on their existing relationship since 2019.

GE Renewable Energy advanced manufacturing technology leader Matteo Bellucci said “This agreement, which will further strengthen our ability to use COBOD’s 3D printing technology and competences in the renewable energy space, is another sign of our commitment to help drive the energy transition by investing in technology that promotes a more sustainable, circular design strategy and helps to create local jobs.” He continued “Since we started cooperating with COBOD, the company has continued to improve their technical competence and innovative solutions, reinforcing the benefits of solidifying the relationship between our companies.”
