A critical assumption of studies assessing comparatively waste management options concerns the constant average cost for selective collection regardless the source separation level (SSL) reached, and the neglect of the mass constraint. The present study compares alternative waste management scenarios through the development of a desktop model that tries to remove the above assumption. Several alternative scenarios based on different combinations of energy and materials recovery are applied to two imaginary areas modelled in order to represent a typical Northern Italian setting. External costs and benefits implied by scenarios are also considered. Scenarios are compared on the base of the full cost for treating the total waste generated in the area. The model investigates the factors that influence the relative convenience of alternative scenarios.
评估比较垃圾管理方案的一个关键假设是,无论达到的源头分类水平(SSL)如何,选择收集的平均成本保持不变,而且忽略了质量约束。本研究通过开发一个台式模型来比较替代垃圾管理方案,该模型试图消除上述假设。基于不同的能源和材料回收组合,应用了几种替代方案,以两个虚拟区域为模型,以代表典型的意大利北部环境。还考虑了方案所涉及的外部成本和收益。根据处理该区域产生的全部废物的总成本对方案进行了比较。该模型研究了影响替代方案相对便利性的因素。
