This study examines the effects of incorporating polyurethane foam waste into gypsum-based ceiling tiles. It compares its economic performance and eco-efficiency with conventional alternatives. Methodologically, Life Cycle Cost Analysis (LCCA) quantifies total life cycle costs, followed by Eco-Efficiency Assessment (EE), considering results from both Life Cycle Assessment (LCA) and LCCA. Our findings reveal a compelling 5.91% cost advantage for the novel precast, driven by enhanced production capacity resulting from shorter drying times. The economic benefits of this approach are underscored by a detailed breakdown of cost savings in production phases. Furthermore, the EE remarks a substantial 7.5% boost, emphasizing the positive environmental impact achieved through reduced resource consumption and lower emissions combined with lower life-cycle costs. These results highlight the economic viability and eco-efficiency of polymeric waste-integrated gypsum ceiling tiles for environmental sustainability. The specific percentage improvements in cost and eco-efficiency provide a quantitative basis for understanding the advantages of adopting these innovative materials. 2214-5095 http://hdl.handle.net/10259/9307 10.1016/j.cscm.2024.e03052 Building material Circular economy Eco-efficiency Assessment Gypsum ceiling tile Life Cycle Cost Analysis Polyurethane foam waste Eco-efficiency and economic assessment of gypsum-based precast with polymeric waste: A case study
