基于生命周期评价法模型的废旧轮胎翻新的环境效益评价

Environmental Benefit Assessment of End-of-Life Tire Refurbishment Based on the Life Cycle Assessment(LCA)Model

对废旧轮胎进行翻新是减少资源消耗和环境污染,促进产业循环经济发展的重要手段。本文选择全钢巨胎为研究对象评价了废旧轮胎翻新的环境效益。研究发现,在全钢巨胎生产过程中,原材料投入是环境影响的主要来源。如果按全球平均水平(6.00%)进行翻新,环境总影响将减少4.20%,而按照北美平均水平(47.00%)进行翻新,环境总影响将减少32.90%。这表明,在全钢工程轮胎生产中引入废旧轮胎回收工艺具有较强的环境友好性。鉴于目前我国对废旧轮胎翻新的重视不足,本研究还给出了相应的政策建议。

This paper selects radial off-the-road(OTR)tiresas the subject of study and evaluate the environmental benefits of the tire refurbishment process.The study reveals that,in the production cycle of radial OTR tires,the major sources of environmental impact are the input of raw materials.If tire refurbishing were conducted at the global average rate of 6.00%,the total environmental impact would be reduced by 4.20%.Conversely,if conducted at the North American rate of 47.00%,the reduction in environmental impact could reach 32.90%.This suggests that integrating used tire recycling processes into the production of radial OTR tires has significant environmental advantages.Given the inadequate attention to tire refurbishment in China,the study further provides pertinent policy recommendations.
