Carbon emission analysis and evaluation of engineering refurbished tire based on life cycle

构建了基于生命周期分析的工程翻新轮胎碳排放模型,提出了工程翻新轮胎生产阶段、运输阶段、使用阶段和再利用4个阶段碳排放的理论计算模型及计算方法,提出了工程翻新轮胎净碳盈余、碳削减模型及碳削减率等碳排放评价指标,定量分析了工程翻新轮胎生产阶段、运输阶段及使用阶段的碳排放清单,分析了二次翻新、燃烧分解、机械粉碎、燃烧发电、低温粉碎等5种典型再利用阶段的碳排放-削减清单,并进行了各阶段的碳排放对比分析及评价.结果表明:工程翻新轮胎生产阶段的碳排放最大,运输阶段的碳排放最小,二次翻新的碳排放削减效果最好,燃烧分解、低温粉碎的碳排放削减效果最差.

The carbon emission models of engineering refurbished tire were constructed based on life cycle analysis,and the theoretic calculation model and the calculation method of carbon emission were proposed for four stages of engineering refurbished tire with production,transportation,usage and recycle.The carbon emission evaluation indexes of pure carbon surplus,carbon subduction model and carbon subduction rate of engineering refurbished tire were given,and the carbon emission lists at production,transportation and usage stages of engineering refurbished tire were quantitatively analyzed.The carbon emission-subduction lists of five recycling stages of second refurbishment,combustion decomposition,mechanical smash,power generation by combustion and low temperature smash were analyzed,and the comparing analysis and evaluation of carbon emissions at different stages were performed.The results show that the carbon emission of engineering refurbished tire is maximal at production stage and is minimal at transporting stage.The carbon emission subduction efficiency of second retreading is the best,while those of combustion decomposition and low temperature smash are the worst.
