At a local Government level there have been many interventions and changes made to household waste collection services to meet new regulatory requirements. These changes include separate collection of recyclable and organic materials. This paper has used a time series model to quantify the success of interventions introduced by a LA. The case study was a medium sized UK LA, Charnwood Borough Council (CBC), the research analyses monthly data of quantities of recyclates, garden waste for composting and residual waste for landfill disposal. The time series model was validated with a five year data set and used to measure the impacts of the various changes to identify which intervention was the most successful, while controlling for season and number of working days. The results show the interventions analysed both had abrupt and permanent positive impacts on the yield of recyclable materials, and a corresponding negative impact on the residual waste. The model could be added to the National data base to help LAs to compare interventions and to understand which schemes encourage householder participation and improve recycling performance.
在地方政府层面，为满足新的监管要求，对家庭垃圾收集服务进行了诸多干预和变革。这些变革包括对可回收材料和有机材料进行分类收集。本文采用时间序列模型来量化一个地方当局所推行干预措施的成效。案例研究对象是英国一个中等规模的地方当局——查恩伍德自治市议会（CBC），该研究分析了可回收物数量、用于堆肥的花园垃圾以及用于填埋处置的残余垃圾的月度数据。时间序列模型通过一个五年数据集进行了验证，并用于衡量各种变革的影响，以确定哪种干预措施最为成功，同时控制季节和工作日数量。结果表明，所分析的干预措施对可回收材料的产量均产生了突然且持久的积极影响，对残余垃圾则产生了相应的负面影响。该模型可添加到国家数据库中，以帮助地方当局比较不同的干预措施，并了解哪些方案能够鼓励居民参与并提高回收绩效。
