Life cycle assessment (LCA) methodology was used to determine the optimum municipal solid waste (MSW) management strategy for Eskisehir city. Eskisehir is one of the developing cities of Turkey where a total of approximately 750tons/day of waste is generated. An effective MSW management system is needed in this city since the generated MSW is dumped in an unregulated dumping site that has no liner, no biogas capture, etc. Therefore, five different scenarios were developed as alternatives to the current waste management system. Collection and transportation of waste, a material recovery facility (MRF), recycling, composting, incineration and landfilling processes were considered in these scenarios. SimaPro7 libraries were used to obtain background data for the life cycle inventory. One ton of municipal solid waste of Eskisehir was selected as the functional unit. The alternative scenarios were compared through the CML 2000 method and these comparisons were carried out from the abiotic depletion, global warming, human toxicity, acidification, eutrophication and photochemical ozone depletion points of view. According to the comparisons and sensitivity analysis, composting scenario, S3, is the more environmentally preferable alternative. In this study waste management alternatives were investigated only on an environmental point of view. For that reason, it might be supported with other decision-making tools that consider the economic and social effects of solid waste management.
生命周期评估(LCA)方法被用于确定埃斯基谢希尔市的最佳城市固体废物(MSW)管理策略。埃斯基谢希尔是土耳其的发展中城市之一,每天产生的垃圾总量约为750吨。由于产生的城市固体废物被倾倒在一个没有衬垫、没有沼气收集等设施的无管制倾倒场,因此该市需要一个有效的城市固体废物管理系统。因此,制定了五种不同的方案作为当前废物管理系统的替代方案。这些方案考虑了废物的收集和运输、材料回收设施(MRF)、回收利用、堆肥、焚烧和填埋过程。使用SimaPro7库来获取生命周期清单的背景数据。选择埃斯基谢希尔的一吨城市固体废物作为功能单元。通过CML 2000方法对替代方案进行了比较,并从非生物耗竭、全球变暖、人体毒性、酸化、富营养化和光化学臭氧消耗的角度进行了这些比较。根据比较和敏感性分析,堆肥方案S3是更环保的替代方案。在本研究中,仅从环境角度对废物管理替代方案进行了调查。因此,它可能需要其他考虑固体废物管理的经济和社会影响的决策工具的支持。
