The Chemistry of Construction
- Cement clinker
Ground with gypsum into blended cement, 1,709 tonnes a year from the Cells that make it - Quicklime
1,677 tonnes a year, produced for $37.74 per tonne against a conventional price of $60 to $75 - Calcined clay
Supplementary cementitious material, fired at 800 degrees Celsius - Fired brick
2,289 tonnes a year, with the Crushing and Milling Plant and the Solar Drying Kiln - Pure carbon dioxide
A clean process stream, captured as a product, and the release step of the Carbon Capture Cell - Activated carbon
47 tonnes a year of water filter grade, steam activated from the char of the Pyrolysis Reactor in resource recovery
