| الوصف: | The economic model of the construction sector is becoming more circular by emphasizing sustainability at all stages from the design, the production phase, the installation, the use, the removal and finally its transport to landfill. This work analyses the influence of added polyurethane foam waste from refrigerated industry on the technical properties (bulk density, water vapor permeability, and reaction to fire performance). The environmental properties were also measured through a comparative Life Cycle Analysis (LCA) between the traditional gypsum ceiling tile and a new organic one. The re-use of polyurethane waste in ceiling tiles causes technical improvements. The most relevant improvements noticed are the decrease in the density (28%), reduction in thermal conductivity (27%) and A1 classification for fire reaction. The comparative (LCA) between both tiles shows that the new product that incorporates polyurethane waste has significant improvement in CO2 (14%) and lower use of energy during the manufacturing process (14%). The following impact categories were also reduced: 9% in the case of the acidification of the ground and water, 9% for eutrophication and 31% reduction for non-hazardous waste. This work intends to reduce the carbon footprint and increase the sustainability of polyurethane gypsum products. © The Authors, published by EDP Sciences. |
