Waste collection and transport can generate up to 70% of the total costs of the system. Separated collection of recyclables implies additional costs for which the sale of recycled waste often does not compensate, but there is increased pressure to reach the long-term recycling objectives set by law. The proper estimation and monitoring of waste collection costs are essential to define the most cost-effective waste collection system. The aim of this study is to propose and implement a management tool to determine waste collection costs for different waste collection schemes. Based on input data, such as waste quantity and composition, the number of waste bins, the location of collection points, the type of collection vehicle, crew, collection route, etc., the developed tool can calculate the time and costs of waste collection (per vehicle, collection point or tonne of collected waste). This tool uses Excel spreadsheets and it was tested on a district in the central area of the city of Kragujevac to calculate the costs of waste collection for two scenarios: Collecting all waste as mixed waste, and collecting separately recyclables and residual waste. The developed tool can be useful for municipal solid waste management companies, since it allows benchmarking and variance analysis.
垃圾收集和运输成本可能占到整个系统总成本的70%。可回收物的分类收集意味着额外的成本，而回收垃圾的销售往往无法弥补这些成本，但要实现法律规定的长期回收目标，压力也在不断增大。对垃圾收集成本进行恰当的估算和监测，对于确定最具成本效益的垃圾收集系统至关重要。本研究的目的是提出并实施一种管理工具，以确定不同垃圾收集方案的成本。基于诸如垃圾数量和成分、垃圾桶数量、收集点位置、收集车辆类型、工作人员、收集路线等输入数据，所开发的工具能够计算垃圾收集的时间和成本（按每辆车、每个收集点或每吨收集垃圾计算）。该工具使用Excel电子表格，并在克拉古耶瓦茨市中部地区的一个区进行了测试，以计算两种情况下的垃圾收集成本：将所有垃圾作为混合垃圾收集，以及分别收集可回收物和残余垃圾。所开发的工具对城市固体废物管理公司可能有用，因为它可以进行基准对比和差异分析。
