Enhanced Landfill Mining targets the zero-waste valorisation of landfills by converting waste to energy and materials. During pre-treatment heterogeneous waste is separated into different fractions. Refuse Derived Fuel is a largely organic fraction, from which an energy-rich syngas can be produced by gasification. A promising technology for this is high temperature plasma, allowing (1) the destruction of tars and 2) the collection of inorganic constituents in a molten slag that can be valorised after cooling, typically as construction material. To simulate the interaction of gas and slag in the plasma reactor, a pseudo-kinetic FactSage-based model was developed, assuming local thermodynamic equilibrium between part of the gas and slag phases. The interaction level was accounted for by varying the amount of slag that equilibrates with the gas. The valorisation potential of the gas and slag phases was evaluated in terms of the heat of combustion and the mineralogy after cooling, respectively.
