CPV code 90524400 designates Collection, transport and disposal of hospital waste in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
90524400 is a leaf code — the most specific level of its branch — so it can be used directly as the main CPV code of a contract notice. If it does not quite fit, check the neighbouring codes under 90524000 (Medical waste services).
