This contribution aims at elucidating the highly complex field of waste management under international administrative law. Addressing the issue from the perspective of the relevant Swiss public actors on the international plane rather than under the aspect of conflict resolution, the author starts by outlining both the challenges of the topic at hand as well as different aspects of extraneity. Subsequently, the analysis focusses on four issues: the identification of the applicable norms; the public actors; their competences; and the different instruments at their disposal (norms, plan, decision, contract, and factual measure (acte matériel/Realakt). In the author's view, the multiple dimensions- internal, European and international- of waste management should be acknowledged. In addition, the advent of a green economy may also spur new legal approaches. Experts on administrative law should take these developments into account, which will render a purely national approach to waste management moot: internationalisation and Europeanisation affect not only the substantive law, but also administrative procedure.
