Abstract: Various examples are provided related to manufacturing portland cement with thermal plasma. In one example, a method includes providing a raw kiln feed to a plasma arc gasification kiln; and forming clinker by heating the raw kiln feed in the plasma arc gasification kiln. The raw kiln feed can be heated with a plasma plume supplied with argon gas to a temperature in a range from about 1800°C to about 3000°C. In another example, a system includes a kiln feed system and a plasma arc gasification kiln that receives raw kiln feed from the kiln feed system and heats the raw kiln feed with a plasma plume to form clinker. The system can include a clinker processing system configured to process the formed clinker to produce portland cement.

Abstract: The present disclosure provides for devices, systems, and methods of separating PFAS compounds from wastewater leachate. After separation, the PFAS compounds can be rendered less harmful. The present disclosure provides for devices, systems, and methods that uses aeration-induced foaming to isolate PFAS from landfill leachate into a concentrated, volume reduced liquid (coalesced foam), which can be separated and treated.
