摘要
采用投入产出分析方法和目标规划方法,以某建陶企业为代表,建立了建筑陶瓷产业投入产出模型及低碳优化模型,利用投入产出模型计量和预估了建筑陶瓷产业关键环节碳排放和产品碳足迹;应用低碳优化模型对建筑陶瓷企业的产品计划进行了低碳优化.结果表明,建筑陶瓷企业年二氧化碳排放量达182 543.9 t,单位产品碳排放量多于国外先进水平10%以上;影响建筑陶瓷产业二氧化碳排放的关键环节为烧成和喷雾干燥过程,烧成和喷雾干燥过程排放的二氧化碳占总排放的80%以上;3种建筑陶瓷产品中,坯砖、抛光砖、釉面砖的万平米产量碳足迹依次为150.2、168.0、159.6 t.建筑陶瓷企业经低碳模型优化后可以在保证同样利润的同时降低5.4%的碳排放,也可以在保证碳排放相同的条件下使利润提高5.6%.
Input-output model and low carbon programming model on building ceramic industry were established.Carbon dioxide emissions of key steps and carbon footprint of products were calculated and predicted using the input-output model.While products planning was optimized using the low carbon programming model.The results showed that CO2 emission in the enterprise reached 182 543.9 t a year and CO2 emission per unit product was 10% more than advanced level in the world.80% of the total CO2 was emitted during the processes of firing and drying.As a result,we should focus on these two steps in order to reduce carbon dioxide emission of building ceramic industry.Carbon footprint of blank tile,polished tile,and glazed tile were 150.2 t,168.0 t,159.6 t respectively.Optimized by the low carbon model,The ceramic enterprise could reduce carbon dioxide emission by 5.4% while not sacrificing any profit,and also could obtain profit 5.6% higher than before while unrise the carbon dioxide emission.
