This paper provides a detailed analysis of the waste footprint and waste treatments at subnational level, for Brussels, Flanders, and Wallonia. The paper details the waste footprint components into direct waste from households (disposed in bins), indirect waste generated upstream in the supply chains and induced by household consumption and waste materials from the degradation of in-use stocks. For each component, we analysed the contribution of waste types, products consumed and location where the waste was generated, as well as the associated treatments.

The results show that Flanders had the highest total waste footprint in absolute terms; Brussels the highest direct waste in capita terms and Wallonia the highest indirect waste and stock depletion in capita terms. In each region, almost 78 ± 2% of the regional waste footprints were attributed to the consumption of food products, manufactured products and restaurants and accommodation services. For each region, around 45 ± 4% of the indirect waste was generated within its boundaries, 16 ± 9% in other regions and 39 ± 5% out of Belgium. Incineration was the predominant waste treatment type of the regional waste footprint, followed by recycling. Landfill was the second widely applied treatment for indirect waste. Results constitute key information relevant to enhance the waste data monitoring practices at regional level with effects at national level. We unveiled the waste footprint and associated treatments inherent to the interregional and international linkages. Results are also useful resources to substantiate waste management and circular economy policies, enacting on waste prevention and reduction, ecodesign and product lifetime extension.

本文对布鲁塞尔，法兰德斯和瓦隆大区的国家以下地区的废物足迹和废物处理进行了详细分析。本文详细介绍了废物足迹组成部分，这些废物成分包括家庭直接废物（放置在垃圾箱中），供应链上游产生的间接废物，这些间接废物是由家庭消费和使用中的存货降解引起的废物造成的。对于每个组成部分，我们分析了废物类型，消耗的产品和产生废物的地点以及相关处理的贡献。

结果表明，就绝对值而言，法兰德斯的总废物足迹最高。以人均计算，布鲁塞尔是最高的直接废物，而按人均计算，瓦隆是最高的间接废物和库存消耗。在每个地区，将近78±2％的地区废物足迹归因于食品，工业产品以及饭店和住宿服务的消费。对于每个区域，其边界内产生了大约45±4％的间接废物，其他区域产生了16±9％，比利时以外的地方产生了39±5％。焚化是区域废物足迹的主要废物处理类型，其次是回收。垃圾掩埋是第二种广泛应用的间接废物处理方法。结果构成关键信息，有助于加强区域一级的废物数据监测做法，并在国家一级产生影响。我们揭露了区域间和国际联系固有的废物足迹和相关处理方法。结果对于证实废物管理和循环经济政策，制定废物预防和减少，生态设计和延长产品寿命也很有用。
