Urban waste management plays an important role in providing secondary raw materials for packaging waste recycling. To assess measures for this provision, material flows of packaging waste for 2006–2020 in Vienna were modeled and evaluated by the separate collection rate and sorting rate. Results showed increasing separate collection rates for the years 2006-2020 for plastic bottles (20%-35%), aluminum beverage packaging (10%-22%), and beverage cartons (10%-18%) achieved by commingled collection and more collection points. Values for other aluminum (6%-5%) and ferrous metal packaging (18%-16%), however, decreased. Glass packaging increased slightly (53%-55%) and paper packaging remained constant (56%). The sorting rate of metal packaging increased significantly due to bottom ash sorting. To increase the provision of secondary raw materials, better communication with consumers and the improvement of technical sorting of mixed waste and bottom ash should be implemented. Door-to-door collection of beverage cartons, metals, and plastics should be carefully tested and evaluated before implementation.

城市垃圾管理在为包装垃圾回收提供二次原料方面发挥着重要作用。为了评估这项规定的措施，我们对 2006-2020 年维也纳包装废物的物质流进行了建模，并通过单独收集率和分类率进行了评估。结果显示，2006-2020 年塑料瓶 (20%-35%)、铝制饮料包装 (10%-22%) 和饮料纸盒 (10%-18%) 通过混合收集等实现了单独收集率的提高收集点。然而，其他铝 (6%-5%) 和黑色金属包装 (18%-16%) 的价值有所下降。玻璃包装略有增长（53%-55%），纸包装保持不变（56%）。由于底灰分选，金属包装的分选率显着提高。增加二次原料供应，加强与消费者的沟通，改进混合垃圾和底灰的技术分类。饮料纸盒、金属和塑料的上门收集在实施前应仔细测试和评估。
