摘要
选择规范PAS2050作为石化产品碳足迹研究的基础方法依据,以某企业生产的沥青产品为评价对象,对该企业的沥青产品碳足迹进行研究,温室气体核算时间范围为2014年1—12月。分别对原料获取阶段、运输阶段、生产阶段、配送阶段和使用阶段的碳排放情况进行研究,得到原料获取阶段、运输阶段、生产阶段、配送阶段和使用阶段的碳排放系数分别为0.208,3.901×10^(-3),0.057 85,0.117,2.570 8t/t,最终得出该企业生产的沥青产品碳足迹为2.957 5t/t。在沥青全生命周期各阶段中,沥青使用过程的温室气体排放量最大,占全部排放量的86.92%。降低沥青环境影响的主要措施是将沥青循环利用,减少使用过程的温室气体排放。
Carbon footprints of asphalt products were studied by PAS2050 standard method.The time boundary for greenhouse emission evaluation is limited in 2014.The examined stages included the raw material acquisition,production,transportation,distribution and end-using.The results indicated that the carbon emission coefficient for each stage is 0.208,3.901×10^(-3),0.057 85,0.117,2.570 8 t/t of asphalt.The carbon footprint of asphalt product is 2.957 5 t/t.The maximum emission of greenhouse gas is in the end-using stage of asphalt,taking over 86.92% of the total emission in whole life cycle.The main measures for reducing the environmental impact of the asphalt are reduction of greenhouse emission in end-using stage and asphalt recycle utilization.
