摘要
采用物质流分析方法,分析了中国废旧轮胎的流动和代谢情况,并提出了优化对策.结果表明:2011~2019年,废旧轮胎产生量呈逐年增长趋势,年均增长率为4.56%,主要来自重型载货汽车.中国废旧轮胎呈现产生量高、回收利用率低的典型特征,材料回收是主要的资源化形式,资源化路径以再生胶生产工艺和胶粉制备工艺为主,热裂解工艺增长显著.废旧轮胎资源化工艺材料利用率较高,未被利用的材料主要以橡胶颗粒物和有机气体等废物形式排入环境,集中于再生胶生产工艺.本研究针对废旧轮胎产生、回收和资源化利用等方面提出管理对策建议,以支撑废旧轮胎资源化产业可持续管理工作.
Material flow analysis(MFA)was used to quantitatively analyze the material flow and metabolism of waste tire treatment in China.Some strategies for optimizing the management status of waste tires were also proposed.The results show that waste tire generation in China presented continuous growth from 2011 to 2019.The generation was mainly from the heavy-duty trucks.Waste tire recycling in China had typical characteristics with large volume generation and low recycling rate.Material recycling was the primary recycling form and reclaimed rubber production was the most crucial recycling pathway.The recycling technologies of waste tires had a high material utilization rate.The released materials in the recycling processes were discharged in the form of rubber particles and organic gas emissions.Reclaimed rubber production was also the primary source of these released materials.Based on the results of material flow analysis,this paper proposed some countermeasures and suggestions associated with the generation,collection,and recycling stages,which were expected to support the optimization of sustainable management of the waste tire recycling industry in China.
