Sources: (1) Registrations according to EU Regulation 259/93 on shipments of waste, (2) Payment of subsidies for recovery of waste oil, (3) ISAG reports 1996 and 1997, (5) Elsam, (6) The figure for special treatment covers that the quantity is in storage. (7) Kommunekemi A/S, (8) Calculations by the Danish Environmental Protection Agency. The difference between total quantity of waste hermetically closed nickel-cadmium batteries (120 tonnes) and the amount collected for recycling (95 tonnes) is due to the fact that the batteries are not collected separately, but comprised by the general collection of waste, (9) Under the terms of Statutory Order no. 660 of 24th September 1986 on asbestos from the Ministry of Labour, asbestos is divided into three categories: I) dust emitting asbestos, II) asbestos that may emit dust, and III) non-dust emitting asbestos. Only asbestos of the first category is hazardous waste, but reports to the ISAG comprise asbestos of both categories I and II.
