Beneficial use of waste relies on efficient systems for collection and separation. In Sweden, a bring system involving recycling centres for collection of bulky, electr(on)ic and hazardous waste has been introduced. A significant share of this waste is incorrectly sorted, causing downstream environmental implications. At present, however, there is a lack of affordable and accurate monitoring methods for providing the recycling centres with the necessary facts for improving the sorting of waste. The aim of this study was therefore to evaluate the usability of a simplified and potentially more suitable waste monitoring method for recycling centres. This method is based on standardised observations where the occurrence of incorrect sorting is monitored by taking digital pictures of the waste which then are analysed according to certain guidelines. The results show that the developed monitoring method could offer a resource-efficient and useful tool for proactive quality work at recycling centres, involving continuous efforts in developing and evaluating measures for improved sorting of waste. More research is however needed in order to determine to what extent the obtained results from the monitoring method are reliable.
废物的有益利用依赖于高效的收集和分离系统。在瑞典，引入了一种涉及回收中心的收集系统，用于收集大件、电子和危险废物。这些废物中有很大一部分分类不正确，对下游环境造成影响。然而，目前缺乏经济实惠且准确的监测方法，无法为回收中心提供改进废物分类所需的事实依据。因此，本研究旨在评估一种简化且可能更适合回收中心的废物监测方法的可用性。该方法基于标准化观察，通过拍摄废物的数字照片来监测不正确分类的发生情况，然后根据某些指南对照片进行分析。结果表明，所开发的监测方法可以为回收中心的主动质量工作提供一种资源高效且有用的工具，需要不断努力开发和评估改进废物分类的措施。然而，需要进一步的研究来确定监测方法获得的结果在多大程度上是可靠的。
