Switzerland: The Cement Sustainability Initiative (CSI) has published a technology review on current and anticipated developments that can be used to mitigate CO2 emissions in cement production. The report includes 52 individual papers on existing technologies and seven additional summary papers
The CSI initiated a review of its original technology papers, which were originally developed in 2009, when the sector issued the first ever low-carbon technology roadmap in partnership with the International Energy Agency (IEA), following the United Nations Framework Convention on Climate Change (UNFCCC) Paris Agreement. The European Cement Research Academy (ECRA) and a stakeholder consultant processes have also supported the project.
Key technological fields covered in the current review include: thermal energy efficiency, electric energy efficiency, use of alternative fuels, materials and biomass, reduction of the clinker content in cement, new binding materials, CO2 capture and storage (CCS), and CO2 use (CCU). The report also includes an assessment of the level of possible implementation, the challenges and costs of these technologies in future scenarios for 2030 and 2050.
“The publication of these revised and new technical papers sets robust foundations for the overall exercise of updating our 2009 roadmap. It is also a major step in the implementation of commitments made by the cement sector in Paris through the Cement Low Carbon Technology Partnerships initiative (LCTPi) and it demonstrates that the business is more than ever focused on supporting the implementation of the Paris Agreement,” said Philippe Fonta, managing director of the CSI.
The CSI and IEA plan to share the initial results of the updated global technology roadmap for the cement sector at COP 23 in Bonn, Germany.
