Paper Title
Comparative LCA on Using Solid Recovered Fuels as Co-Firing Substitute in Cement Plant

Abstract
The study examines the global warming potential of cement clinker production in Taiwan using Life Cycle Assessment (LCA) software, OpenLCA v2.1.1. Solid Recovered Fuel (SRF) respectively as alternative fuel. The comparison of cement company’s base scenario is done with the proposed scenarios to draw LCA results. The LCA result shows that cement production has significant environmental impacts due to fossil fuel burning and import of raw materials. The clinkerization of limestone has the highest carbon footprint, i.e., 0.4166 tons of CO2e per ton of fuel. Therefore, using SRF or other biomass fuels as co-firing materials in the calcination of limestone clinker in the cement industry can help reduce greenhouse gas emissions and mitigate impacts and damages to the ecosystem.
