Problem
Conventional Portland cement production, a 200-year-old process, accounts for 8% of global greenhouse gas emissions, releasing 2.2 billion tons of CO2 annually. This is due to the burning of fossil fuels to achieve reaction temperatures of 2600 °F (1450 °C) and the CO2 emitted directly from the chemical reaction itself.
Solution
Chement is developing a zero-emissions cement manufacturing technology that replaces highly-polluting coal-fired kilns with an electrochemical process powered by renewable electricity. This method uses the same raw materials but requires less energy and emits less CO2. The technology also facilitates carbon capture that is cheaper and easier than carbon capture in conventional cement production.
Target Audience
The primary target audience includes companies in the construction and building materials industries seeking to reduce their carbon footprint, as well as governments and organizations focused on sustainable infrastructure development.
Features
- Electrochemical process powered by renewable electricity, eliminating the need for fossil fuels
- Utilizes the same raw materials as traditional cement production
- More energy-efficient than conventional methods
- Enables easier and cheaper carbon capture of unavoidable process emissions
