Abstract

Recently, the amount of waste generated in Korea has been increasing, and there have been difficulties disposing of it. As an energy-intensive and raw-materials-oriented industry, the cement industry is facing challenges including overcoming the climate crisis and achieving carbon neutrality. Co-processing was suggested as a solution, but the environmental effects of this have not been specifically studied in Korea. In this study, the effects of using alternative resources (limestone, silica stone, iron ore, and gypsum) and fuel on greenhouse gas (GHG) emissions in the cement industry in Korea were analyzed. GHGs generated from mineral mining were compared to GHGs of alternative resources. The reduction in GHGs by using alternative fuel was calculated via the amount of heat from waste instead of that from bituminous coal. Co-processing can reduce approximately 106.9 kg of CO 2 in one ton of cement. The cost savings were estimated to be about USD 3815 million. In addition, the lifespans of landfills would be extended by 7.55 years.
