Cement: A Really Hard Problem

Cement production significantly contributes to global CO2 emissions, accounting for 8% of total emissions. The process of making clinker, a key component of cement, releases a large amount of CO2. While concrete can absorb some CO2 over time, it is insufficient to offset emissions. Efforts to reduce cement's carbon footprint include using alternative energy sources, reducing clinker content, and incorporating industrial waste. Innovative companies like Solidia are developing new methods to use CO2 in cement production, making it more efficient and environmentally friendly. However, the cement industry is resistant to change, and new technologies must prove commercially viable to be adopted.
