Germany: Holcim, E.ON Energy Infrastructure Solutions and Orcan Energy have launched a large-scale waste heat recovery project at Holcim’s Dotternhausen cement plant to capture 10MW of unused heat from kiln exhaust gases. The recovered heat will supply internal processes, potential district heating networks and power generation via Orcan Energy’s eP1000 Organic Rankine Cycle (ORC) system. E.ON is responsible for the planning, construction, financing operation and maintenance of the plant as part of an Energy-as-a-Service model. This is intended to present no initial investment costs for Holcim.

Holcim South Germany plant manager Dieter Schillo said “This project marks an important milestone on our path to decarbonising cement production. The smart use of industrial waste heat not only reduces our Scope 2 emissions, but also strengthens our role as a pioneer in sustainable building materials.”

Germany: Holcim Germany has published environmental reports for 2020 focused on each of its cement plants. The subsidiary of Switzerland-based Holcim has decided to target its reports on local issues by issuing separate reports for each of its four integrated plants in the country, at Beckum, Höver, Lägerdorf and Dotternhausen respectively. Each report covers national developments for the sector and the company. Local data is then included as well as data on connected cement grinding and concrete plants. The reports can be downloaded from Holcim Germany’s website.

Germany: A Zollernalb, Baden-Württemberg resident who mounted legal action against Tübingen Council in June 2019 over LafargeHolcim subsidiary Holcim Süddeutschland’s use of waste glass in cement production at its 1.1Mt/yr integrated Dotternhausen plant has submitted ‘extensive reasoning’ for the challenge. The Schwarzwälder Bote has reported that Holcim Süddeutschland allegedly did not complete the proper tests before introducing glass to cement production at Dotternhausen in late 2017. The claimant ‘noticed a rise in heavy metal levels.’

At a subsequent council meeting, a Holcim Süddeutschland employee bore witness to the presence of a defective bag filter. By receiving glass ground to grains of a certain fineness, the claimant alleges that Holcim Süddeutschland was able to bypass federal waste regulations necessitating contaminant checks. They said the company was ‘taking citizens for idiots.’
