Utilization of Municipal Solid Waste Incineration (MSWI) Landfill Real Flue Gases Mixed with KR-Slag for CO2 Sequestration - Pilot Scale Demonstration

Municipal solid waste is being produced in large quantities, in keeping with a dramatic population increase and the growth of industrialization. Most of this waste is sent to landfills in South Korea. However, current treatment methods, including incineration and recycling is limited owing to insufficient landfill space and the generation of leachates and soil contamination. This study seeks to determine the degree of influence of several main factors, such as the optimum temperature, solid-to-water ratio and CO₂ concentration, on the process of accelerated carbonation of the landfill flue gases (7% concentration) mixed with KR slag.  This paper presents the experimental results obtained from a pilot scale demonstration of landfill real flue gases mixed with KR slag. This demonstration was performed with the capacity of 20 tons/hour.
