A new study entitled ’Towards a business case for CO2 mineralisation in the cement industry’ revealed that – through techno-economic modelling – the notoriously hard-to-abate cement industry could see a reduction in carbon dioxide equivalent (CO2e) emissions and additional profit by incorporating CO2 mineralisation.
According to best estimates, the cement industry is responsible for approximately 7% of anthropogenic CO2e emissions and, in 2015, the Paris climate agreement emphasised the need for signatories to limit CO2e emissions and strive for a temperature rise of 1.5C.
The challenge of reducing these emissions in the cement industry stems from the majority (60%) of its emissions being process-inherent, meaning that to lower emissions either the entire process must be replaced by more sustainable alternatives or the emissions generated through the process must be captured and stored.
