Antimony (Sb) in urban and industrial waste and in waste incineration
The sources of antimony (Sb) in municipal waste and the consequences of the presence of antimony in input of waste incinerators were investigated. It is concluded that more than 50% of the antimony is originating from all types of flame retardants and that about 35% of the antimony stream is coming from flame retardants from consumer electronics. The remainder is coming from metal and miscellaneous applications of antimony. There is a tendency to decrease the application of halogenated products (and thus of antimony) in flame retardants. Also the other fields of application of antimony show a decreasing trend. There are no indications that a substantial increase of the concentration of antimony in the feed to municipal waste incinerators will occur in the near future. During the incineration process, the antimony compounds are only found in the bottom ash and in the fly ash. No volatile Sb compounds are present in the flue gas. This means that efficacious particle removal systems are sufficient for a complete Sb removal during incineration.
