摘　　要：为现有瓷质餐具包装的环境友好性提供理论数据,文章以一套瓷质餐具为例,采用生命周期评价(LCA)方法,对瓦楞纸箱、发泡聚苯乙烯生产过程的原料能源消耗,运输物质消耗及向环境的排放物进行计算和特征化分析并进行环境影响评价,总环境影响潜力为EIL=0.25。结果表明:其对环境的影响主要产生于包装产品的运输过程,主要影响了资源消耗和全球变暖等环境影响类型。减小其产生的环境影响,产品生产厂家应就近选择包装供应商,生产厂家就近销售,在各地设置分厂分销产品。To provide the theoretical data of environmentally friendly, the existing packaging of ceramic tableware was studied. According to the method of Life cycle assessment(LCA),computing and characterization analysis the environmental effect load was 0.25 eq.(/pa)for one packaging. Its come from the energy consumption of the raw material for corrugated boxes and expanded polystyrene production process and the transportation material consumption and emissions to the environment. The results show that the main environmental impacts caused by the consumption and global warming which were produced by transport. To reduce the environmental impact, product manufacturers should choose the nearest packaging suppliers and nearest sales, and set up branch in various distributions.
