Belgium: Holcim Belgium has received an environmental permit for the kiln upgrade for its 100% decarbonisation of its Obourg cement plant. Agency Belgium News has reported that the upgraded kiln will employ a 'new incineration concept' to enable it to replace limestone with alternative raw materials. It will reduce the plant's thermal needs by 40% and its CO2 emissions per tonne of clinker by 30%. Construction will commence in late 2023. The kiln replacement will support a carbon capture installation as part of the GO4ZERO project.
The first phase of the GO4ZERO project is running from 2022 to 2025, and commands total investments of over Euro350m.
