Swiss researchers combine DAC with cement production
In Switzerland, cement is one of the most in-demand building materials of our time. Every year, around four billion tonnes are produced. Cement production is energy-intensive, and greenhouse gases are emitted during the process – particularly during the thermal decomposition of limestone, the most important natural raw material for cement.
In a new study, ETH researchers show that these emissions could be significantly reduced if cement production were combined with a technology for the direct removal of CO₂ from the atmosphere, known as Direct Air Capture (DAC).
