Abstract:
A three-tiered approach to classification of incinerator bottom ash (IBA) from grate furnace installations incinerating non-hazardous waste under the proposed new EU regulations for hazard assessment of waste with reference to the new chemicals legislation has been established and applied to European IBA, based on 95 percentile values of composition data obtained for up to 1700 bottom ashes from 9 European countries. Tier 1 is a screening based on gross characteristics of the waste, Tier 2 is a conservative assessment based on total composition data, whereas Tier 3 is a more precise assessment of the hazardous properties and substances not eliminated in Tiers 1 and 2, based on leaching data and chemical speciation modelling. With a few reservations for properties for which no test methods currently exists, the results indicate that European IBA at 95 percentile level will be non-hazardous when applying this procedure to the proposed revised classification rules.
