Classification of waste as
hazardous or non-hazardous

(Site in Swedish here) Latest update: 2018-01-18

 

GENERAL INFORMAITON

The information that appeared on this webb page earlier can be found here. The previous information is, however, still largely valid and up tp date even if the rules regarding the actual calculations have been changed radically during the years 2014-2018. The main reason for this is that the legislation for labelling of chemical substances have changed.

An account of how classification might be carried out according to the legislation that is presently in force can be found in the report "Classification of residues from combustion and incineration as hazardous or non-hazardous waste". It is in Swedish but has a brief summary in English. There is also a concomitant tool for calculations. Both documents can be found below under the heading REFERENCES. The work was financed by  the Ash Programme at Energiforsk - the Swedish Energy Research Centre, Avfall Sverige – the Swedish Waste Management Association, and the Swedish Energy Agency.    

New legislation regarding ecotoxic properties have been issued, EU-regulation 2017/997, and they will come into force on July 5th, 2018.

Anyone in the European Union in possession or in custody of waste is obligated to know how it is classified, i. e. if it is hazardous or non-hazardous. The primary responsibility for this rests with the entity that is generating the waste. The classification has significance for the handling and management of the waste, and in come cases - and in some countries - this also includes the disposal.

Classification of incinerator ash and similar wastes is, however, somewhat of a "mission impossible" in view of the very complex chemical form. This is why a special method has been developed. There are reasons to believe that such classifications are cautious even if the uncertainty is high. An important such reason is that certain trace elements are bonded in the form of solid solution. Such bonding has been dealt with in the report on stabilization of lead, see below as well as on documents included in the old webb page.

The reason for compiling the new classification report is to make it possible for many to make classifications themselves, and this includes various consultants that can be of help with such work. Tekedo has supported many companies in Sweden with classification, and also helped organizations abroad in a few cases.
