The current practice of the University is to treat individual department as a chemical waste producer. There are currently 21 departments who have been registered as “producers”. With proper registration being made, chemical waste can be collected with proper containers provided by Enviropace Ltd, ie the licensed chemical waste collector, and disposed of in compliance with the Regulation. Chemical waste stores are used to store these chemical wastes centrally as a temporary measure prior to the eventual collection by Enviropace Ltd. Should user departments have any chemical waste to be disposed of which does not have a chemical waste ID no., user departments could complete a New Chemical Waste Information Form (FMO TS12 access via downloadable forms) and send to FMO. Upon receipt of the information, FMO will check with Enviropace Ltd. whether the chemical waste in question can be accepted by Enviropace Ltd or not. If any chemical waste is refused to be accepted by Enviropace Ltd, user department should seek advice from HSEO.
