In paragraph 5 of decision BC-13/17, the Conference of the Parties to the Basel Convention requested the Secretariat to prepare, for consideration of the Open-ended Working Group at its eleventh meeting, a document compiling information on existing activities that address waste containing nanomaterials and identifying issues related to waste containing nanomaterials that may be relevant to work under the Convention and on options for further work that may be carried out under the Basel Convention related to waste containing nanomaterials within the scope of the Convention, avoiding duplication with activities relating to the matter in other forums.
Since then, the Conference of the Parties has reiterated its request to the Secretariat, through the decisions BC-14/14, BC-15/16 and BC-16/13, to continue compiling the information related to activities aimed at addressing issues related to waste containing nanomaterials, including case studies about and best practices relating to the management of waste containing nanomaterials submitted by the Parties and others.
