Regular weekly collection
Buildings equipped with a hazardous waste storage are placed on a regular weekly pick-up. Users are asked to bring their full containers to these areas and exchange them for empty containers. For safety reasons, only containers approved by Hazardous Waste Management can be stored in those rooms.
Periodic collection is usually arranged when a large clean-up of chemical waste is required or scheduled by a building director as part of a yearly building sweep. This type of collection is mostly reserved for laboratory chemicals and require special packaging.
