Abstract: Various examples related to portland cement manufacturing using municipal solid waste incineration (MSWI) ash are provided. In one example, a method includes providing a raw kiln feed including MSWI to a kiln, forming ash-amended clinker (ACK) by heating the raw kiln feed in the kiln, and preparing ash-amended cement (AAC) from the ACK. The MSWI bottom ash can make up about 5% by mass or less of the raw kiln feed. The ACK can have a chemical composition that meets ASTM C150/ASTM C595, and the AAC can include arsenic, barium, copper, and lead consistent with defined Soil Cleanup Target Levels. In another example, a system includes a kiln, a kiln feed system that supplies raw kiln feed including MSWI bottom ash to the kiln, and a finish mill that grinds ACK formed by heating the raw kiln feed in the kiln to form AAC.
