Abstract
Glass wool is the roll felt product produced by melting and fiberizing glass and then adding adhesive for curing processing. It is well-shaped, thermally insulated and corrosion resistant and has low volume density, low thermal conductivity, good acoustic absorptivity and stable chemical properties. By taking 1t glass wool as the functional unit, this paper quantitatively obtains that the impact of the product on primary energy demand, greenhouse effect, acidification potential, photochemical ozone formation potential and respirable inorganics is 1.12×105MJ/t, 8×103kg CO2 equivalent/t, 84.1kg SO2 equivalent/t, 3.21kg NMVOC/t and 15.5kg PM2.5 equivalent/t respectively. This paper provides reference for enterprise's cleaner production and consumer's green material selection by making life cycle assessment for glass wool insulation material, quantifying the environmental load of glass wool product, identifying the environment hot spots in product life cycle and illustrating the environment compatibility of product.
