Life Cycle Assessment of Typical Rubber-Plastic Sponge Production in China

Abstract:

As a kind of high-grade flexible insulation and energy-saving material, rubber-plastic sponge insulation material is produced by taking butadiene-acrylonitrile rubber and polyvinyl chloride as main materials, together with auxiliary materials such as fire retardant, plasticizer, foaming agent and filler, through production processes as weighing stock, pre-smelting, mixing, extrusion, foaming and cutting and packaging. By taking 1m³ rubber-plastic sponge 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 2,100MJ/m³, 74.9kg CO₂ equivalent/m³, 0.356kg SO₂ equivalent/m³, 0.244kg NMVOC/m³ and 0.0642kg PM2.5 equivalent/m³ respectively. This paper provides reference for enterprise's cleaner production and consumer's green material selection by making life cycle assessment for rubber-plastic insulation material, quantifying the environmental load of the product, identifying the environment hot spots in product life cycle and illustrating the environment compatibility of product.
