Emission of Trace Organics From Municipal Solid Waste Incinerators—Rationale of National Guidelines in the Federal Republic of Germany

Abstract

In the Federal Republic of Germany a working party has developed recommendations for dealing with the dioxin problems posed by waste incineration. According to these recommendations limit values for dioxin emissions are neither necessary nor practical. However, from the point of view of preventive environmental protection, dioxin emissions should be further reduced as far as is possible with present-day technology. The TA Luft (Technical Instructions for Maintaining Air Quality) contains stipulations and advice on this. The most significant of the solid residues from waste incinerators are the filter ashes as they have a high dioxin content. The working party of Länder (states) has compiled a catalogue of recommendations for the disposal of filter ashes. The transport of solid residues from solid waste incinerators is controlled under the Abfallgesetz (Waste Act) and regulations passed in connection with this act and under the Gefahrgutverordnung Strasse—GGVS (Regulation on the transport of dangerous freight by road). The latter stipulates at what level of dioxin certain transport conditions must be respected. The new Gefahrstoffverordnung—GefStoffV (Regulation on dangerous substances) prohibits substances containing dioxin in concentrations above a certain level from being placed on the market. It does not apply to residues from solid waste incinerators.
