Abstract

The escalating generation of construction and demolition waste (C&DW) owing to the rapid increase in population and the per capita generation (PCG) index as an urban development metric has triggered numerous research endeavors aimed at formulating effective mechanisms and strategies to manage this waste stream. This study aims to assess the efficacy of economic instruments in promoting C&DW reuse and diverting waste from sanitary landfills using the System Dynamics (SD) tool and scenario simulations spanning the period 2020 to 2040 in the municipality of Serra, Espírito Santo (ES). Our findings reveal that the PCG index exerts a staggering 84-fold greater influence on C&DW generation compared to that of population growth. Additionally, we observe that the implementation of a public policy, such as a landfill tax, can substantially augment aggregate recycling by 124 times when comparing the highest tax rates (6%) to the lowest tax rates (2%). Nevertheless, even under the best-case scenario, our analysis demonstrates a potential rise of 76,000 tons of illegal dumping, leading to an approximate cost increase of 10 million dollars for C&DW management until 2040. To enhance future investigations, we suggest the inclusion of penalties and subsidies in the model to comprehensively evaluate their impact on C&DW management alongside the taxation applied to landfill disposal. This multifaceted approach can provide valuable insights for devising more effective waste management strategies.
基于系统动力学的建筑与拆除废弃物管理经济评价模型——以塞拉斯市为例
由于人口的快速增长和城市发展指标的人均产生量(PCG)指数,建筑和拆除废物(C&DW)的产生量不断增加,引发了许多旨在制定有效机制和策略来管理这一废物流的研究工作。本研究旨在利用系统动力学(SD)工具和情景模拟,评估经济工具在促进C&DW再利用和从卫生垃圾填埋场转移废物方面的功效,时间跨越2020年至2040年,位于Espírito Santo (ES)的Serra市。我们的研究结果表明,与人口增长相比,PCG指数对C&DW产生的影响要大84倍。此外,我们观察到,当将最高税率(6%)与最低税率(2%)进行比较时,公共政策(如垃圾填埋税)的实施可以将总回收率大幅提高124倍。然而,即使在最好的情况下,我们的分析表明,非法倾倒可能增加76,000吨,导致到2040年的生化武器管理成本增加约1,000万美元。为了加强未来的调查,我们建议在模型中包括罚款和补贴,以全面评估它们对垃圾填埋场处理的税收影响。这种多方面的方法可以为制定更有效的废物管理战略提供宝贵的见解。
